An enterprise DevOps team is designing the GKE deployment architecture for two upcoming microservices:

1. A stateless HTTP API service that experiences sudden, unpredictable load spikes and requires hands-off node infrastructure management with zero operational overhead for cluster upgrades.
2. A specialized network security monitoring daemon that requires elevated Linux privileges (`CAP_SYS_ADMIN`) and direct access to the host node network namespace (`hostNetwork: true`).

Which GKE deployment and cluster configuration strategy correctly fulfills both application requirements while adhering to Google Cloud recommended best practices?

Deploy the stateless HTTP API service to a GKE Autopilot cluster, and deploy the network security daemon to a GKE Standard cluster with a dedicated node pool.

Deploy both microservices to a single GKE Autopilot cluster using separate Kubernetes namespaces and custom pod security standards.

Deploy both microservices to a single GKE Standard cluster using Spot VM node pools for both workloads to minimize operational costs.

Deploy the HTTP API service to GKE Standard using a Horizontal Pod Autoscaler (HPA) configured to scale the node pool VM instance count, and deploy the daemon to GKE Autopilot.

Cevabı ve açıklamayı göster

Cevap: Deploy the stateless HTTP API service to a GKE Autopilot cluster, and deploy the network security daemon to a GKE Standard cluster with a dedicated node pool.

Cevap

Deploy the stateless HTTP API service to a GKE Autopilot cluster, and deploy the network security daemon to a GKE Standard cluster with a dedicated node pool.

The correct strategy separates the workloads based on GKE operational boundaries. GKE Autopilot provides fully managed node provisioning, scaling, and maintenance for stateless workloads without infrastructure management overhead. However, Autopilot restricts host network binding (`hostNetwork: true`) and elevated Linux capabilities (`CAP_SYS_ADMIN`). Consequently, the privileged monitoring daemon must be deployed to a GKE Standard cluster where node configuration and pod security settings can be customized.

Adım Adım Çözüm

Evaluate the operational and security constraints of GKE Autopilot.

GKE Autopilot manages all node infrastructure, provisioning, and OS patching, making it ideal for stateless web workloads. However, to maintain cluster security, Autopilot blocks capabilities such as hostNetwork: true, hostPort, and elevated Linux capabilities like CAP_SYS_ADMIN.

Security boundaries in GKE Autopilot prevent workloads from modifying host node networking or kernel capabilities.

Evaluate requirements for the privileged monitoring daemon.

The network security daemon requires host network namespace access and CAP_SYS_ADMIN privileges, which are supported in GKE Standard node pools where administrators have full control over node configurations and pod security contexts.

GKE Standard allows custom node pool management and unrestricted Pod Security Standards when explicitly configured.

Synthesize the cluster architecture selection.

Combining GKE Autopilot for the hands-off HTTP API service and GKE Standard for the privileged security daemon satisfies all operational and technical requirements.

This workload segregation respects GKE feature boundaries while following Google Cloud architectural guidelines.

A developer has created a Google Kubernetes Engine (GKE) cluster to host an application. Before running `kubectl` commands to manage workloads on the cluster, the developer must retrieve cluster access credentials and configure the local command-line environment. Which `gcloud` command should the developer run to update the local `kubeconfig` file with these credentials?

gcloud container clusters get-credentials my-cluster --zone us-central1-a

gcloud config set container/cluster my-cluster

gcloud container node-pools describe my-cluster --zone us-central1-a

gcloud compute instances describe my-cluster-node --zone us-central1-a

Cevabı ve açıklamayı göster

Cevap: gcloud container clusters get-credentials my-cluster --zone us-central1-a

Cevap

Execute `gcloud container clusters get-credentials my-cluster --zone us-central1-a` to automatically populate the local kubeconfig file with cluster endpoints and security credentials.

Executing `gcloud container clusters get-credentials` authenticates against the specified GKE cluster and writes the required certificate authority data, cluster endpoint, and user token into the local `kubeconfig` file. This establishes the active context needed for `kubectl` to communicate with the cluster API server.

Adım Adım Çözüm

Identify the CLI tool required to authenticate kubectl with a GKE cluster.

The gcloud container component provides cluster credential integration.

kubectl requires an active context entry containing the cluster API server endpoint and authorization certificate.

Select the exact command designed to fetch cluster credentials.

`gcloud container clusters get-credentials` updates `~/.kube/config`.

This command generates authentication entries so kubectl commands seamlessly talk to the GKE control plane.

An enterprise IoT solutions provider is designing a Google Kubernetes Engine (GKE) cluster architecture to host two distinct workloads. The first workload is a specialized edge telemetry receiver that requires custom Linux kernel parameters (sysctl settings) configured directly on the underlying node OS. The second workload is a stateless, fault-tolerant data transformation pipeline that processes incoming message queues and must run at the lowest possible infrastructure cost. The operations team aims to minimize management complexity while meeting all technical requirements. Which cluster architecture recommendation best fulfills these requirements?

Deploy a single GKE Standard cluster. Create one node pool with standard Compute Engine instances for the edge telemetry workload to support custom kernel parameters, and create a separate node pool utilizing Spot VMs for the stateless data transformation pipeline.

Deploy a single GKE Autopilot cluster for both workloads, configuring pod security settings to allow the edge telemetry workload to apply sysctl kernel modifications at runtime.

Deploy a GKE Standard cluster configured with a single node pool of Spot VMs to host both the edge telemetry receiver and the data transformation pipeline.

Deploy a GKE Standard cluster using standard instances, and configure the Horizontal Pod Autoscaler (HPA) to provision new Compute Engine nodes whenever worker node CPU usage exceeds limits.

Cevap: Deploy a single GKE Standard cluster. Create one node pool with standard Compute Engine instances for the edge telemetry workload to support custom kernel parameters, and create a separate node pool utilizing Spot VMs for the stateless data transformation pipeline.

Cevap

Deploy a single GKE Standard cluster with a standard node pool for the telemetry receiver and a Spot VM node pool for the stateless transformation pipeline.

The solution correctly identifies that custom Linux sysctl kernel configurations necessitate GKE Standard because GKE Autopilot restricts host OS kernel modifications. Additionally, using a dedicated Spot VM node pool for the stateless transformation pipeline optimizes costs without risking the stability of the telemetry receiver.

Adım Adım Çözüm

Analyze the operational boundary between GKE Autopilot and GKE Standard.

GKE Autopilot manages the underlying infrastructure and restricts node-level OS modifications, including custom sysctl parameters. Therefore, GKE Standard is required for the telemetry receiver workload.

GKE Autopilot enforces strict security posture and node management boundaries that prevent custom host OS kernel configuration.

Evaluate node pool cost-optimization strategies for the stateless workload.

Spot VMs provide significant cost savings (up to 60-91% off standard pricing) and are ideal for fault-tolerant, stateless batch workloads that can handle instance preemptions.

Segmenting workloads into separate node pools allows tailored instance selection and cost optimization per workload profile.

Synthesize the cluster architecture design.

A GKE Standard cluster with two dedicated node pools (Standard VMs for telemetry; Spot VMs for stateless processing) satisfies technical and budget constraints.

This setup maintains cluster operational efficiency while respecting underlying node OS customization and fault tolerance boundaries.

A cloud engineer needs to configure automated cost-control actions triggered by Cloud Billing budget alerts using a serverless event architecture. Arrange the following deployment steps in the correct chronological order required to set up this workflow.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct sequence starts with granting the appropriate IAM permissions on the Cloud Billing account, followed by creating the destination Cloud Pub/Sub topic, configuring the Cloud Billing budget linked to that Pub/Sub topic, and finally deploying the Cloud Function subscriber to handle automated remediation logic.

The correct order establishes prerequisite security permissions first, provisions the messaging infrastructure second, binds the billing budget alert policy to the Pub/Sub endpoint third, and implements the serverless consumer logic fourth. This sequence ensures all dependency relationships (permissions -> Pub/Sub topic -> budget binding -> event consumer) are satisfied without workflow errors.

Adım Adım Çözüm

Ensure IAM administrative access for Cloud Billing.

The engineer has permission to manage billing budget alerts and export configurations.

Without roles such as Billing Account Costs Manager or Billing Account Administrator, budget modifications and pub/sub sink settings cannot be saved.

Provision the Cloud Pub/Sub notification endpoint.

A Pub/Sub topic is established to receive automated JSON alert messages from Google Cloud Billing.

Google Cloud Billing budgets require an existing Pub/Sub topic identifier when attaching a programmatic notification channel.

Create the Cloud Billing budget and link the Pub/Sub topic.

Budget threshold rules are active and configured to publish messages to the Pub/Sub topic when spending targets are met.

Budget alert policies send events to the Pub/Sub topic only after explicit association in the billing console or gcloud command.

Deploy the event-driven subscriber logic via Cloud Functions.

An automated listener receives Pub/Sub event notifications and executes administrative actions to stop workloads or cap costs.

Budget notifications do not automatically stop resources by default; custom code in Cloud Functions/Run is required to parse notifications and invoke GCP APIs to enforce cost limits.

Cevabı ve açıklamayı göster

Cevap: gcloud container clusters get-credentials prod-app-cluster --region=us-central1

Cevap

The command `gcloud container clusters get-credentials prod-app-cluster --region=us-central1` must be executed to update the local kubeconfig file.

Executing the command `gcloud container clusters get-credentials prod-app-cluster --region=us-central1` authenticates to Google Cloud, retrieves the cluster endpoint certificates, and writes an authenticated context entry directly into the local `kubeconfig` file so that `kubectl` can target the cluster.

Adım Adım Çözüm

Identify why kubectl fails with a localhost:8080 error.

Recognize that kubectl defaults to localhost:8080 when no valid target API server context exists in the local ~/.kube/config file.

Before kubectl can target a remote GKE cluster, local credentials and context entries must be populated.

Determine the correct gcloud CLI command to populate cluster credentials.

Select `gcloud container clusters get-credentials` along with the cluster name and region flag.

This command generates security tokens, fetches cluster endpoint IPs, and constructs the current-context entry inside kubeconfig.

An organization operates a custom-mode Virtual Private Cloud (VPC) in Google Cloud. A network engineer is tasked with expanding the primary IP range of `subnet-east` to accommodate additional compute instances.

The current VPC subnet allocation and connected routes are configured as follows:
- `subnet-east` primary IP range: $10.80.12.0/23$ ( $10.80.12.0 - 10.80.13.255$ )
- `subnet-west` primary IP range: $10.80.14.0/23$ ( $10.80.14.0 - 10.80.15.255$ )
- `subnet-central` primary IP range: $10.80.8.0/23$ ( $10.80.8.0 - 10.80.9.255$ )
- On-premises network (via Cloud VPN): $10.80.0.0/21$ ( $10.80.0.0 - 10.80.7.255$ )

The engineer plans to expand `subnet-east` to a $/22$ prefix length to double its IP capacity. Which statement accurately describes the outcome and requirements for this expansion?

The expansion will fail because the only valid

The expansion will succeed if `subnet-east` is expanded to

10.80.10.0/22

, utilizing the unused IP addresses between `subnet-central` and `subnet-east`.

The expansion will succeed if `subnet-east` is expanded to

10.80.8.0/22

, because Google Cloud automatically re-aggregates adjacent subnets within the same VPC.

The expansion will fail because Google Cloud subnets can only be expanded if the original prefix length is

Cevap

The correct sequence starts with building and tagging the container image locally, pushing the image to Google Cloud Artifact Registry, updating the container image on the GKE deployment using kubectl set image, and finally verifying the deployment progress using kubectl rollout status.

The workflow follows standard container lifecycle and Kubernetes deployment practices: first creating the local container image, pushing it to Google Cloud Artifact Registry so GKE can access it, applying the image update to the deployment manifest via kubectl, and lastly inspecting the rollout status to confirm workload health.

Adım Adım Çözüm

Build and tag the application image locally.

A tagged container artifact exists locally ready for deployment repository upload.

Containerized workloads require a built image artifact prior to registry publishing.

Publish the image to Google Cloud Artifact Registry.

The image artifact becomes accessible to the GKE worker nodes.

GKE nodes pull container images from centralized cloud registries during pod scheduling.

Update the GKE workload image using kubectl set image.

GKE initiates a rolling update to replace existing pod replicas with the new container image version.

An administrator needs to relocate an existing Google Cloud project from a parent folder named `Staging` to another folder named `Production` within the organization resource hierarchy. The administrator already has the `Project Editor` role directly on the project being relocated, but the migration attempt fails with a permission denied error. Which administrative role or permission requirement explains why this move was denied?

The administrator requires permissions to detach the project from the source folder and attach it to the destination folder, requiring write permissions on both folders in addition to project update rights.

The Project Editor role grants sufficient authority on the project, but permissions inherited from the child project level automatically override parent folder policies to block folder-to-folder movement.

Moving projects between folders cannot be accomplished using predefined roles and strictly requires assigning the primitive Organization Owner role at the root organization node.

The project must first be unlinked from its central Cloud Billing Account because active billing account associations prevent moving projects between resource hierarchy folders.

Cevabı ve açıklamayı göster

Cevap: The administrator requires permissions to detach the project from the source folder and attach it to the destination folder, requiring write permissions on both folders in addition to project update rights.

Cevap

The administrator requires write/move permissions on both the source and target parent folders in addition to update permissions on the project itself.

To move a GCP project between folders in the resource hierarchy, an identity must hold rights on all affected nodes: project update permissions on the project being moved, as well as parent modification/move rights (such as `resourcemanager.projects.move` or Project Mover role) on both the source parent folder and the target parent folder.

Adım Adım Çözüm

Analyze resource hierarchy movement permission requirements

Identified that moving a GCP project affects three distinct hierarchy nodes: the project itself, the source parent folder, and the destination parent folder.

Google Cloud IAM evaluates access control at every affected level of the resource hierarchy.

Evaluate permissions granted by the Project Editor role

The Project Editor role grants `resourcemanager.projects.update` on the project, which satisfies the project-level requirement.

Editing the project configuration is only one part of relocating a resource.

Determine missing folder-level IAM permissions

The operation fails because the user lacks permissions to modify the project list of the source folder (removing the project) and the destination folder (adding the project).

Granting appropriate predefined roles (e.g., Project Mover or Folder Admin) at the source and destination folder levels fulfills the least-privilege requirement for moving projects.

Cevap

The correct sequence begins with drafting the local YAML role definition file with launchStage set to ALPHA, followed by creating the role at the organization level with gcloud iam roles create, testing the role assignment on a project via gcloud projects add-iam-policy-binding, and finally updating the role's launch stage to GA via gcloud iam roles update.

Declarative custom IAM role creation follows a structured lifecycle: defining the specification in YAML with an initial ALPHA stage, instantiating the role in GCP using gcloud iam roles create, testing permission effectiveness by binding the role to a test principal, and finally updating the role's launch stage to GA using gcloud iam roles update.

Adım Adım Çözüm

Define the custom role structure locally in YAML.

A valid YAML configuration file containing title, description, permissions list, and ALPHA launch stage.

gcloud CLI declarative role creation requires a pre-configured YAML file containing the permission payload.

Create the organization custom role via gcloud CLI.

The custom IAM role is instantiated at the organization resource level.

Creating the role makes its resource identifier available across child projects in the resource hierarchy.

Bind the role to a service account for integration testing.

The identity receives the defined permissions within the specific test project scope.

A cloud engineer is designing a custom-mode Virtual Private Cloud (VPC) network. The current setup includes a primary subnet in `us-central1` configured with a CIDR block of $10.10.1.0/24$ and another primary subnet in the same VPC configured with $10.10.2.0/24$ . Due to anticipated growth, the engineer needs to double the IP address capacity of the $10.10.1.0/24$ subnet without re-creating the subnet or disrupting existing workloads. Which CIDR range configuration update is valid and prevents IP range overlap?

Expand the subnet primary IP range to

10.10.0.0/23

Expand the subnet primary IP range to

10.10.1.0/23

Change the VPC mode from custom-mode to auto-mode to allow Google Cloud to automatically expand subnets.

Add a non-contiguous secondary CIDR range of

10.10.3.0/24

directly to the primary IP range of the subnet.

Cevap: Expand the subnet primary IP range to $10.10.0.0/23$ .

Cevap

Expand the subnet primary IP range to

10.10.0.0/23

Expanding the primary CIDR block of a custom-mode subnet requires keeping the range contiguous and aligned to proper binary network boundaries. Expanding

10.10.1.0/24

10.10.0.0/23

covers IP addresses from

10.10.0.0

10.10.1.255

, incorporating the original range, doubling capacity to

512

addresses, and avoiding collision with the existing

10.10.2.0/24

subnet.

Adım Adım Çözüm

Analyze the starting primary IP address range and target capacity expansion.

The subnet currently uses

10.10.1.0/24

(

256

IP addresses). Doubling capacity requires a

/23

prefix (

512

IP addresses).

Expanding a subnet primary CIDR block requires shifting to a smaller prefix length while remaining contiguous.

Evaluate valid

/23

network boundaries that include

10.10.1.0/24

/23

subnet boundary aligned on binary boundaries covers

10.10.0.0

10.10.1.255

(represented as

10.10.0.0/23

10.10.1.0/23

is not a valid network address base; the network address for this

/23

block is

10.10.0.0/23

Verify there is no IP range overlap with other subnets in the VPC.

10.10.0.0/23

covers

10.10.0.0

–

10.10.1.255

, which does not collide with the neighboring subnet at

10.10.2.0/24

Google Cloud VPC subnet expansion fails if the new expanded CIDR range overlaps with any pre-existing subnets in the network.

A cloud engineer is using the Google Cloud Pricing Calculator to model monthly operational costs for a mission-critical production workload running continuously 24/7 year-round. The architecture requires 20 Compute Engine instances for base application traffic and a 10 TB data layer that will be queried and updated multiple times per day. Which configuration strategy in the Google Cloud Pricing Calculator provides the most accurate and cost-effective estimate for this workload?

Specify 3-year Committed Use Discounts (CUDs) for the 20 Compute Engine instances and select Standard Cloud Storage for the frequently accessed 10 TB data layer.

Combine automatic Sustained Use Discounts (SUDs) with 3-year Committed Use Discounts (CUDs) for the Compute Engine instances, and select Archive Storage to minimize baseline storage costs.

Configure all 20 Compute Engine instances as Spot VM instances to maximize discount percentages, and select Coldline Storage for the active data layer.

Model the application layer using GKE Autopilot pods with Archive Storage for the active data layer, while assuming node management fees will cover data egress and storage access.

Cevap: Specify 3-year Committed Use Discounts (CUDs) for the 20 Compute Engine instances and select Standard Cloud Storage for the frequently accessed 10 TB data layer.

Cevap

Specify 3-year Committed Use Discounts (CUDs) for the 20 Compute Engine instances and select Standard Cloud Storage for the frequently accessed 10 TB data layer.

The correct strategy specifies 3-year Committed Use Discounts (CUDs) for the continuous 24/7 Compute Engine workload to lock in the maximum discount rate available in the Google Cloud Pricing Calculator. For the data layer accessed multiple times daily, Standard Cloud Storage is required because nearline, coldline, and archive tiers incur expensive data access and retrieval fees that outweigh their lower baseline at-rest storage costs.

Adım Adım Çözüm

Evaluate compute usage pattern and discount options in the Google Cloud Pricing Calculator.

Identify that a continuous 24/7 mission-critical workload operating over long horizons qualifies for Committed Use Discounts (CUDs), which yield higher cost savings than Sustained Use Discounts (SUDs) and cannot be stacked together.

CUDs commit to a specific amount of resource usage for 1 or 3 years, overriding automatic SUDs.

Assess storage class access requirements based on workload access frequency.

Determine that data accessed multiple times per day requires Standard Cloud Storage to avoid operational retrieval fees.

Coldline and Archive storage tiers have low at-rest pricing but high data retrieval fees, making them cost-prohibitive for active data.

Synthesize compute and storage choices to select the optimal calculator configuration.

Combine 3-year CUDs for VMs with Standard Cloud Storage for active data.

This combination achieves maximum valid compute savings while eliminating unexpected storage retrieval penalties.

A cloud security administrator at a biotechnology firm needs to grant a lead bio-informatician the required privileges to link a newly provisioned Google Cloud project, `genomics-pipeline-prod`, to the enterprise Cloud Billing Account. The administrator must strictly adhere to the principle of least privilege, ensuring the bio-informatician cannot manage payment details or alter billing account permissions. Which IAM role combination should be granted to the bio-informatician?

Billing Account User (roles/billing.user) on the Cloud Billing Account and Project Billing Manager (roles/resourcemanager.projectBillingManager) on the target project

Billing Account Administrator (roles/billing.admin) on the Cloud Billing Account and Owner (roles/owner) on the target project

Billing Account User (roles/billing.user) on the Cloud Billing Account only

Project Billing Manager (roles/resourcemanager.projectBillingManager) on the target project only

Cevabı ve açıklamayı göster

Cevap: Billing Account User (roles/billing.user) on the Cloud Billing Account and Project Billing Manager (roles/resourcemanager.projectBillingManager) on the target project

Cevap

Grant Billing Account User (roles/billing.user) on the Cloud Billing Account and Project Billing Manager (roles/resourcemanager.projectBillingManager) on the target project.

Linking a Google Cloud project to a Cloud Billing Account requires permissions on both entities. The predefined role Billing Account User (`roles/billing.user`) gives the permission `billing.resourceAssociations.create` on the billing account. The predefined role Project Billing Manager (`roles/resourcemanager.projectBillingManager`) gives the permission `resourcemanager.projects.createBillingAssignment` on the project. This combination grants the exact rights required without over-privileging the user.

Adım Adım Çözüm

Identify the minimum permission required on the Cloud Billing Account

The permission `billing.resourceAssociations.create` is needed, which is provided by the predefined role Billing Account User (`roles/billing.user`).

This allows the user to associate projects with the billing account without granting administrative access over payment settings or billing administration.

Identify the minimum permission required on the target Google Cloud Project

The permission `resourcemanager.projects.createBillingAssignment` is needed, which is provided by the predefined role Project Billing Manager (`roles/resourcemanager.projectBillingManager`).

This allows the user to link or unlink the billing account on that specific project without granting broad primitive roles like Owner or Editor.

Combine both permissions to achieve least privilege compliance

Pairing Billing Account User on the billing account with Project Billing Manager on the project provides exact, dual-side authorization required for project-billing linking.

Google Cloud requires explicit authorization on both resource entities (the billing account and the project).

An enterprise SaaS organization is architecting a Google Kubernetes Engine (GKE) environment to host two distinct workloads with strict operational requirements:

1. A high-throughput custom API gateway service that requires modifying specific OS kernel sysctl parameters (`net.core.somaxconn`) on the underlying cluster nodes.
2. A fault-tolerant, stateless asynchronous batch analytics engine designed to process non-critical queued jobs at minimal cost.

You need to plan a cluster architecture that meets these workload demands while minimizing operational expenditure. Which TWO architectural decisions should you execute?

Geçerli olan tümünü seçin

Deploy a GKE Standard cluster with a custom node pool where kernel sysctl settings can be customized for the API gateway workload.

Provision a dedicated node pool utilizing Spot VMs configured with taints and tolerations for the asynchronous batch analytics workload.

Deploy a GKE Autopilot cluster for the API gateway workload to eliminate node management while applying custom OS sysctl kernel configurations.

Provision a Spot VM node pool to host the primary stateful database instances supporting the SaaS platform.

Cevap: Deploy a GKE Standard cluster with a custom node pool where kernel sysctl settings can be customized for the API gateway workload.; Provision a dedicated node pool utilizing Spot VMs configured with taints and tolerations for the asynchronous batch analytics workload.

Cevap

Select GKE Standard for custom OS kernel sysctl modifications on the node pool, and utilize Spot VMs with taints and tolerations for stateless batch processing workloads.

Choosing GKE Standard enables necessary low-level node kernel modifications (sysctl settings) required by high-throughput network components. Additionally, implementing Spot VMs with proper taints and tolerations enables significant cost reductions for fault-tolerant, stateless batch workloads without exposing critical services to preemption risks.

Adım Adım Çözüm

Analyze the operational boundary requirements for custom OS kernel settings.

GKE Autopilot locks down node-level configurations. Custom sysctl parameters require GKE Standard node pools.

Only GKE Standard allows custom node configuration scripts and low-level kernel tuning.

Analyze the compute cost optimization strategy for the asynchronous batch engine.

Spot VMs provide high discount rates for interruptible, stateless workloads.

Taints and tolerations ensure only the batch processing pods schedule onto Spot VM nodes.

An industrial manufacturing company uploads high-resolution optical inspection images to Google Cloud Storage. Analysis of the data lifecycle reveals the following operational requirements:

- Newly created images are accessed continuously by automated quality assurance systems during the first 30 days.
- Between 31 and 90 days, images are queried infrequently (approximately once per month) for batch defect trend reporting.
- After 90 days, images are rarely accessed but must be kept for 3 years to comply with industrial safety audits.

You need to design a Cloud Storage lifecycle policy that optimizes total operational cost while avoiding premature transition fees and excessive retrieval charges. Which storage class transition strategy should you implement?

Create a bucket with the Standard storage class. Add a lifecycle rule to transition objects to Nearline storage after 30 days, and a second rule to transition objects to Coldline storage after 90 days.

Create a bucket with the Nearline storage class as default. Add a lifecycle rule to transition objects directly to Archive storage after 30 days.

Create a bucket with the Standard storage class. Add a lifecycle rule to transition objects directly to Archive storage after 30 days.

Create a bucket with the Coldline storage class as default. Add a lifecycle rule to transition objects to Archive storage after 90 days.

Cevabı ve açıklamayı göster

Cevap: Create a bucket with the Standard storage class. Add a lifecycle rule to transition objects to Nearline storage after 30 days, and a second rule to transition objects to Coldline storage after 90 days.

Cevap

The correct strategy starts with Standard storage to allow frequent QA reads during the first 30 days without incurring retrieval fees. Transitioning to Nearline after 30 days reduces storage costs while accommodating monthly batch reporting queries. Transitioning to Coldline after 90 days further reduces long-term retention costs for compliance while respecting the 90-day minimum duration policy of Coldline storage.

Adım Adım Çözüm

Analyze the access pattern and minimum duration requirements for the initial 30 days.

Images are continuously accessed during the first 30 days, requiring zero retrieval fees.

Standard storage class has no minimum storage duration and zero retrieval costs, making it the most cost-effective tier for frequently accessed active data.

Analyze the access pattern and minimum duration requirements for days 31 to 90.

Images are accessed once per month, fitting the Nearline access pattern.

Nearline storage is optimized for data accessed less than once a month and requires a 30-day minimum storage duration, matching the 30-day transition threshold.

Analyze the access pattern and minimum duration requirements after 90 days.

Images are rarely accessed over a 3-year compliance period, fitting the Coldline access pattern.

Coldline storage is optimized for data accessed at most once every 90 days and carries a 90-day minimum storage duration, matching the 90-day transition threshold.
