A configuration consisting of

15\text{ GB}

of Amazon DynamoDB storage and

500{}000

AWS Lambda requests per month

The configuration containing Amazon DynamoDB and AWS Lambda requests is correct because both of these service allocations fall under the 'Always Free' category. They do not expire after 12 months, and the requested amounts (

15\text{ GB}

and

500{}000

requests) remain under the monthly free limits of

25\text{ GB}

and

1\text{ million}

requests respectively.

A financial services startup is deploying two workloads on Amazon EC2. The first is a core transaction ledger database that must run continuously with predictable performance and cannot tolerate any service interruptions. The second is a high-throughput, containerized credit-scoring batch analysis job that is stateless, can be safely paused and resumed, and is scheduled to run overnight. Which two of the following EC2 pricing models should the company select to minimize costs for these workloads?

Geçerli olan tümünü seçin

Savings Plans to host the core transaction ledger database to benefit from reduced rates for a consistent amount of compute usage.

Spot Instances to run the credit-scoring batch analysis to take advantage of spare EC2 capacity at steep discounts.

On-Demand Instances to run the credit-scoring batch analysis to prevent any interruption or termination of the overnight jobs.

Dedicated Hosts to run the credit-scoring batch analysis to ensure complete physical isolation and the lowest possible hourly compute rate.

Reserved Instances to host the credit-scoring batch analysis with a 3-year commitment to maximize cost savings for the batch workloads.

Cevabı ve açıklamayı göster

Cevap: Savings Plans to host the core transaction ledger database to benefit from reduced rates for a consistent amount of compute usage.; Spot Instances to run the credit-scoring batch analysis to take advantage of spare EC2 capacity at steep discounts.

Cevap

Savings Plans should be used for the core transaction ledger database to benefit from reduced rates for consistent usage, and Spot Instances should be used for the credit-scoring batch analysis to utilize spare compute capacity at a lower cost.

The correct pricing strategy uses Savings Plans for the continuous, steady-state transaction database, which provides a significant discount over On-Demand rates in exchange for a commitment to consistent compute usage. For the credit-scoring batch analysis, Spot Instances are the optimal choice because the job is stateless and can tolerate interruptions, allowing the company to run it at a fraction of the cost using spare capacity.

Adım Adım Çözüm

Analyze the requirements for the first workload (core transaction ledger database).

The workload runs continuously, requires predictable performance, and cannot tolerate interruptions.

This steady-state, continuous database workload is ideal for commitment-based discount models like Savings Plans or Reserved Instances to minimize cost.

Analyze the requirements for the second workload (credit-scoring batch analysis).

The workload is containerized, stateless, runs overnight, and can tolerate interruptions (paused and resumed).

Because the workload is fault-tolerant and flexible, Spot Instances are the most cost-effective choice, offering up to a 90% discount by utilizing spare EC2 capacity.

Combine the optimal pricing models to select the two correct choices.

Select the option for Savings Plans for the database, and the option for Spot Instances for the batch job.

This combination achieves the lowest cost while meeting the technical requirements of both workloads.

Cevap: Paying only for the compute resources consumed during active simulation runs, aligning operational expenses with actual usage.; Reducing waste by automatically scaling down compute capacity when simulations are not active.

Cevap

Paying only for the compute resources consumed during active simulation runs, aligning operational expenses with actual usage, and reducing waste by automatically scaling down compute capacity when simulations are not active.

The correct options are the statements regarding paying only for the compute resources consumed during active simulation runs and reducing waste by automatically scaling down compute capacity when simulations are not active. Paying only for active use aligns expenses with actual demand, and using elasticity to scale down prevents paying for idle compute time.

Adım Adım Çözüm

Analyze the business scenario and current challenges.

The startup runs sporadic simulation workloads and has a high amount of idle capacity (on-premises servers sized for peak demand sitting idle).

Understanding the baseline operational challenges helps target the specific economic benefits of the AWS Cloud that address them.

Evaluate how AWS pricing models apply to sporadic workloads.

AWS pay-as-you-go pricing allows paying only for what is used (operating expenses) rather than buying servers upfront (capital expenses).

This directly maps to the economic benefit of matching operational costs to usage.

Evaluate how AWS scaling features apply to idle resources.

Leveraging elasticity allows resources to scale up during simulations and down to zero during idle periods, eliminating waste.

This directly maps to the economic benefit of elasticity and cost optimization in the cloud.

SolarPulse, a solar energy analytics company, currently operates an on-premises data center. The company experiences significant seasonal fluctuations in data processing needs, with demand peaking during the summer months. To prevent downtime, they provisioned their on-premises infrastructure to handle this peak load, leaving resources underutilized for the rest of the year. They are planning to migrate their workloads to AWS. Which of the following best describes the cloud economics benefit that directly addresses SolarPulse's underutilization issue?

Elasticity, which enables the dynamic scaling of resources to match demand, minimizing cost waste during low-demand periods.

Scalability, which allows the company to permanently increase its fixed capacity to accommodate future year-round growth.

Transitioning to a fixed cost model using upfront capital expenses (CapEx) to secure volume discounts.

Relying on On-Demand billing to maintain maximum provisioned capacity continuously at a lower rate.

Cevap: Elasticity, which enables the dynamic scaling of resources to match demand, minimizing cost waste during low-demand periods.

Cevap

Elasticity, which enables the dynamic scaling of resources to match demand, minimizing cost waste during low-demand periods.

The option describing elasticity is correct because elasticity represents the ability to dynamically scale resources to match actual demand. This addresses the problem of seasonal underutilization by scaling down resources when demand drops, ensuring the customer only pays for what is consumed.

Adım Adım Çözüm

Analyze the business scenario and identify the primary financial challenge.

SolarPulse experiences seasonal fluctuations in demand, leading to underutilized, idle infrastructure during off-peak months.

Understanding the workload characteristics helps determine which cloud economic principle applies.

Evaluate the cloud economic concept that addresses matching resource supply with varying demand.

Elasticity allows a company to automatically scale up resources during peak periods and scale them down during low-demand periods to eliminate paying for unused capacity.

This allows the workload to dynamically match resource consumption to actual demand, solving the underutilization problem.

Anahtar Kavram

Cevap: AWS Pricing Calculator to estimate the pre-deployment costs, and AWS Budgets to set up the monthly spend alert.

Cevap

AWS Pricing Calculator to estimate the pre-deployment costs, and AWS Budgets to set up the monthly spend alert.

The correct answer combines the AWS Pricing Calculator and AWS Budgets. The AWS Pricing Calculator allows users to input planned resource configurations to estimate costs before any resources are launched. AWS Budgets is then used to track actual costs against a custom limit and send email notifications when defined thresholds are crossed.

Adım Adım Çözüm

Identify the appropriate tool for predicting costs of unlaunched services.

The AWS Pricing Calculator is selected because it is designed to model and estimate AWS costs prior to resource creation.

The agency needs a pre-deployment cost estimate for resources they have not yet provisioned.

Identify the appropriate tool for configuring threshold-based spend alerts.

AWS Budgets is selected because it enables users to establish spending limits and receive notifications (such as emails) when costs exceed those limits.

The agency requires a proactive notification mechanism for when actual monthly spend exceeds a specific threshold.

Anahtar Kavram

Differentiating AWS cost estimation and budget alerting tools.

A financial technology company is launching a digital wallet application on AWS. Due to regulatory compliance, all financial transaction logs must be stored within a specific country's geographic borders. Additionally, the transaction database must remain operational even if an entire data center facility experiences a power failure. Which AWS infrastructure configuration best satisfies both requirements?

Deploy the database in a single Availability Zone within the designated country, and replicate transaction logs to multiple Edge Locations globally.

Deploy the database across multiple AWS Regions, using Edge Locations to host the active database instances in the designated country.

Deploy the application and database across multiple Availability Zones within a single AWS Region located in the designated country.

Deploy the database in a single AWS Region in a neighboring country, and use AWS Local Zones to cache the data locally.

Cevabı ve açıklamayı göster

Cevap: Deploy the application and database across multiple Availability Zones within a single AWS Region located in the designated country.

Cevap

Deploy the application and database across multiple Availability Zones within a single AWS Region located in the designated country.

Deploying the application and database across multiple Availability Zones within a single AWS Region in the designated country satisfies data residency laws by keeping all data within the country's geographic borders, while leveraging multiple isolated Availability Zones ensures high availability and resilience against facility-level outages.

Adım Adım Çözüm

Analyze the data residency requirement.

Select an AWS Region physically located within the designated country's borders.

AWS Regions are geographically isolated areas, and data does not leave a region unless explicitly transferred by the customer, ensuring compliance with local laws.

Analyze the high availability and resiliency requirement.

Deploy the database across multiple Availability Zones (AZs) within the chosen Region.

Availability Zones are isolated locations within a Region, designed to be independent in terms of power, cooling, and networking. This design protects the workload from single data center failures.

Anahtar Kavram

AWS Regions protect data residency while Availability Zones provide high availability within a Region.

An online multiplayer gaming studio is hosting its backend matchmaking service on AWS. The studio wants to achieve two objectives:

1. Run the matchmaking databases in a configuration that remains operational even if one physical data center site experiences a power outage.
2. Store game updates and patch files globally so players can download them with minimal latency.

Which two AWS global infrastructure features should the studio use to achieve these goals? (Select TWO.)

Geçerli olan tümünü seçin

Multiple Availability Zones

AWS Edge Locations

Multiple AWS Regions

AWS Outposts

AWS Local Zones

Cevabı ve açıklamayı göster

Cevap: Multiple Availability Zones; AWS Edge Locations

Cevap

To survive a data center outage, the database must be deployed across multiple Availability Zones. To cache and distribute game files globally with low latency, the studio must use AWS Edge Locations.

Deploying resources across multiple Availability Zones provides local redundancy because each zone is an isolated location with independent power and cooling within an AWS Region. AWS Edge Locations cache content globally, allowing users to download large patch files from locations closest to them rather than pulling from the origin server every time.

Adım Adım Çözüm

Analyze the first requirement: ensuring database operations remain functional during a local data center power outage.

Identify Availability Zones as the isolated infrastructure components within a Region designed to handle single-site failures.

Availability Zones consist of one or more discrete data centers with redundant power, networking, and connectivity, making them the primary tool for high availability within a region.

Analyze the second requirement: distributing large static files (game patches) globally with minimal latency.

Identify AWS Edge Locations as the caching network endpoints.

Edge Locations work with Amazon CloudFront to cache content closer to end-users globally, reducing latency and download times.

Anahtar Kavram

AWS Global Infrastructure components (Availability Zones for local resilience and Edge Locations for global content delivery)
