Cevabı ve açıklamayı göster

Cevap: Go global in minutes; Trade fixed expense for variable expense

Cevap

The correct benefits demonstrated are going global in minutes and trading fixed expense for variable expense.
The logistics provider eliminates upfront hardware costs by trading fixed expense for variable expense under the cloud's pay-as-you-go model. Furthermore, deploying the fleet-tracking application to multiple global regions in minutes demonstrates the ability to go global in minutes.

Adım Adım Çözüm

1
Analyze the first requirement: the logistics provider wants to eliminate large upfront capital expenditures on physical hardware.
This maps to the benefit 'Trade fixed expense for variable expense', as paying only for what is consumed replaces large fixed upfront costs.
AWS allows organizations to pay for resources on-demand, which reduces capital expenditures (CapEx) in favor of operating expenditures (OpEx).
2
Analyze the second requirement: the provider wants to deploy its application across several international regions within minutes to minimize latency.
This maps to the benefit 'Go global in minutes' because of AWS's expansive global infrastructure footprint.
AWS enables rapid multi-region deployment, allowing applications to be close to users with minimal latency.

Cevap: Amazon DynamoDB; Amazon Redshift

Cevap

Amazon DynamoDB and Amazon Redshift
Amazon DynamoDB is a NoSQL key-value database designed to handle high-throughput workloads with single-digit millisecond latency, making it the correct choice for user session state data. Amazon Redshift is a fully managed data warehouse designed specifically to handle complex analytical queries over petabytes of structured data for business intelligence reporting.

Adım Adım Çözüm

1
Analyze the first requirement: a database to store and retrieve user session state data with single-digit millisecond latency at any scale.
Identify that a fully managed NoSQL key-value database like Amazon DynamoDB is optimized for high-throughput, low-latency session store workloads.
Relational databases (like Amazon RDS) do not scale as easily or cost-effectively for millions of concurrent key-value lookups with sub-10ms response times.
2
Analyze the second requirement: a data warehouse solution to run complex analytical queries over petabytes of historical data.
Identify that Amazon Redshift is the dedicated AWS service for data warehousing and Online Analytical Processing (OLAP) at scale.
Standard databases are meant for transaction processing (OLTP) and perform poorly under heavy analytical queries across petabytes of historical data.

A logistics company is hosting a dispatch coordinate management system on Amazon EC2 instances within a Virtual Private Cloud (VPC). A security administrator needs to implement a network security design that meets two criteria:

1. Block a list of specific malicious IP addresses at the subnet boundary before the traffic reaches any resources.
2. Automatically allow return traffic for any authorized inbound connections to the EC2 instances without needing to configure outbound rules.

Which of the following configurations should the administrator implement to meet these requirements? (Select TWO.)

Cevabı ve açıklamayı göster

Cevap: Apply a Network Access Control List (Network ACL) at the subnet level with deny rules to block the malicious IP addresses.; Apply a Security Group at the instance level to allow inbound traffic, relying on its stateful nature to automatically permit return traffic.

Cevap

Apply a Network Access Control List (Network ACL) at the subnet level with deny rules to block the malicious IP addresses, and apply a Security Group at the instance level to allow inbound traffic, relying on its stateful nature to automatically permit return traffic.
The correct strategy combines a subnet-level Network Access Control List (Network ACL) to explicitly block malicious IP addresses (since Network ACLs support deny rules at the subnet boundary) and an instance-level Security Group to control application access (since Security Groups are stateful and automatically permit return traffic for established connections without needing outbound rule configuration).

Adım Adım Çözüm

1
Analyze the requirement to block specific IP addresses at the subnet boundary.
Identify that Network Access Control Lists (NACLs) operate at the subnet level and support explicit deny rules.
Security Groups do not support deny rules and operate at the instance level, so NACLs must be used to block IPs at the subnet boundary.
2
Analyze the requirement to automatically allow return traffic for established connections.
Identify that Security Groups are stateful and automatically track connection states to allow return traffic.
Network ACLs are stateless and require explicit configuration of outbound rules for return traffic, whereas Security Groups automatically handle return traffic.

An enterprise is launching a new microservice on Amazon Elastic Container Service (Amazon ECS) that needs to write data to an Amazon DynamoDB table. Which configuration represents the most secure method for granting the microservice the necessary permissions?

Cevabı ve açıklamayı göster

Cevap: Associate an IAM role with the container task definition, granting it temporary security credentials with write access to the DynamoDB table.

Cevap

Associating an IAM role with the container task definition, granting it temporary security credentials with write access to the DynamoDB table.
Associating an IAM role with the ECS task definition is the recommended practice. It allows the microservice container to retrieve temporary security credentials automatically. This removes the need to store long-term, hardcoded access keys in the code or container environment, minimizing credential exposure.

Adım Adım Çözüm

1
Identify the entity requiring access (a containerized application on ECS) and the target resource (DynamoDB table).
An application running on an AWS compute service needs access to an AWS database service.
Access requirements dictate what type of IAM identity is most appropriate (e.g., role vs. user).
2
Apply the AWS security best practice of using temporary security credentials for applications running on AWS services.
An IAM role must be created and associated with the container task definition rather than creating an IAM user with long-term access keys.
Roles provide temporary credentials that rotate automatically, avoiding the security risk of exposing hardcoded long-term credentials.
3
Define the scope of customer responsibility under the AWS Shared Responsibility Model.
The customer is responsible for configuring access policies and assigning IAM roles to resources.

An enterprise is migrating a legacy, monolithic document management system to AWS. The application requires a storage solution that supports POSIX file permissions and file-locking capabilities. It must be concurrently accessed by a fleet of auto-scaling Linux EC2 instances across multiple Availability Zones, as well as on-premises servers via an existing AWS Direct Connect connection. The performance requirements dictate that throughput must scale dynamically and automatically with the workload's I/O activity, without requiring manual provisioning of throughput capacity. Which AWS storage solution best meets these requirements with the least operational overhead?

Cevabı ve açıklamayı göster

Cevap: Amazon Elastic File System (Amazon EFS) configured with Elastic throughput

Cevap

Amazon Elastic File System (Amazon EFS) configured with Elastic throughput
Amazon Elastic File System (Amazon EFS) is designed for shared file access across multiple Availability Zones and on-premises servers via AWS Direct Connect. By using Elastic throughput, throughput automatically scales in response to workload activity, eliminating the need to manage or provision throughput limits.

Adım Adım Çözüm

1
Identify the file system protocol and access requirements.
The application requires concurrent access across multiple Availability Zones and on-premises servers using a POSIX-compliant interface with file-locking capabilities.
This rules out block storage solutions like EBS (which are AZ-restricted and lack native cross-instance sharing) and object storage like S3 (which lacks full POSIX compliance).
2
Evaluate the scaling and performance management requirements.
Throughput must scale dynamically and automatically without manual intervention or provisioning.

Cevabı ve açıklamayı göster

Cevap: Amazon EC2 Instance Store; Amazon S3 Glacier Flexible Retrieval

Cevap

The correct options are Amazon EC2 Instance Store and Amazon S3 Glacier Flexible Retrieval.
Amazon EC2 Instance Store is correct because it provides temporary, high-speed block storage directly attached to the host computer, which is ideal for temporary scratch files or buffer data that does not need to survive instance stops. Amazon S3 Glacier Flexible Retrieval is correct because it is designed for low-cost archiving of historical data that is rarely accessed, offering retrieval options that take between a few minutes and a few hours.

Adım Adım Çözüm

1
Analyze the first requirement: low-latency, temporary block storage for files that do not need to persist when the EC2 instance stops.
Amazon EC2 Instance Store fits this scenario, as it is physically attached to the host computer and is ephemeral (data is lost when the instance is stopped or terminated).
Instance Store is optimized for temporary block storage and has no ongoing cost if the instance is running, unlike persistent block storage options.
2
Analyze the second requirement: low-cost archival storage for rarely accessed records retrievable within a few hours.
Amazon S3 Glacier Flexible Retrieval fits this scenario, as it is designed for low-cost archiving with retrieval options ranging from minutes to hours.
S3 Glacier provides highly durable and extremely cheap storage for inactive data compared to active storage classes or block storage.

Cevap: Deploy the latency-sensitive game server workloads in an AWS Local Zone located in the target metropolitan area.; Deploy the central database across multiple Availability Zones in the nearest AWS Region.

Cevap

Deploying the latency-sensitive game server workloads in an AWS Local Zone located in the target metropolitan area, and deploying the central database across multiple Availability Zones in the nearest AWS Region.
Deploying game servers in AWS Local Zones allows the application to achieve single-digit millisecond latency close to users in metropolitan areas where there is no primary AWS Region. Deploying the database across multiple Availability Zones within the nearest AWS Region provides physical redundancy and automatic failover capability to protect against local data center disasters.

Adım Adım Çözüm

1
Analyze the requirement for single-digit millisecond latency in a metropolitan area without an AWS Region.
Identify AWS Local Zones as the infrastructure component designed to bring compute, storage, and database services close to major population centers for low-latency requirements.
Regions are geographically dispersed, and when a Region is not present in a metropolitan area, AWS Local Zones fill this gap.
2
Analyze the requirement for database high availability and disaster protection against data center failures.
Identify Multi-AZ deployment as the solution.
Availability Zones are physically isolated data centers within a Region with redundant power, networking, and connectivity, making them the standard choice for localized high availability.
3
Evaluate the distractors based on the roles of Edge Locations, Regions, and CloudFront.

Cevap: Trading upfront capital expenses (CapEx) for variable operating expenses (OpEx) that align costs directly with actual usage; Reducing overall costs by using elasticity to scale down compute resources automatically during periods of low overnight demand

Cevap

The correct options are: trading upfront capital expenses (CapEx) for variable operating expenses (OpEx) that align costs directly with actual usage, and reducing overall costs by using elasticity to scale down compute resources automatically during periods of low overnight demand.
The correct options describe two fundamental cloud economic pillars. First, transitioning to AWS changes spending from upfront capital investments (CapEx) to variable, usage-based operating expenses (OpEx). Second, leveraging elasticity allows the infrastructure to automatically scale down when demand drops overnight, eliminating payment for idle resources.

Cevap: AWS Fargate to deploy the containerized API microservice; AWS Lambda to execute the database logging utility code

Cevap

AWS Fargate to deploy the containerized API microservice, and AWS Lambda to execute the database logging utility code
The correct services are AWS Fargate and AWS Lambda. AWS Fargate is a serverless compute engine that runs containers without the customer needing to provision, configure, or scale virtual machines, which perfectly satisfies the continuous microservice requirement. AWS Lambda is a serverless compute service that automatically runs code in response to events (such as database changes) and scales dynamically, making it the most cost-effective and operationally efficient choice for short-lived logging tasks.

Adım Adım Çözüm

1
Analyze the containerized microservice requirement.
The microservice needs to run continuously and scale automatically without server management.
AWS Fargate matches this containerized serverless requirement because it manages the underlying infrastructure for container execution.
2
Analyze the database logging utility requirement.
The logging utility is short-lived, executes for only a few seconds, and is triggered by database events.
AWS Lambda is the ideal serverless choice for this because it executes code in response to events without running a persistent server.
3
Evaluate and eliminate incorrect compute choices based on operational responsibility and efficiency.
Amazon EC2 requires manual server configuration and OS patching, and running an EC2 instance continuously for occasional database triggers is cost-inefficient.
Eliminating options that violate the AWS Shared Responsibility Model or introduce unnecessary administrative and financial overhead aligns the architecture with AWS best practices.

Cevap

Deploying the workload across multiple Availability Zones in a single AWS Region provides physical separation between data centers while keeping data within the same national boundary, and AWS Local Zones can be used to run latency-sensitive applications closer to end-users in the remote metropolitan city, while maintaining a connection to the parent AWS Region.
The correct options correctly describe the functions of Availability Zones and Local Zones. Multiple Availability Zones within one Region provide redundant, physically isolated power and cooling domains to guarantee high availability while keeping data inside the same country to meet data residency rules. AWS Local Zones place compute and storage services close to metropolitan areas to satisfy low-latency demands for local users.

Adım Adım Çözüm

1
Analyze the high availability and data sovereignty requirement.
Identify that Availability Zones within a single Region provide physical redundancy (isolation from failures) while remaining within the same geographic/political border.
Availability Zones are designed with independent infrastructure (power, cooling, network) but reside in the same Region, satisfying both physical separation and local residency needs.
2
Analyze the low-latency metropolitan user requirement.
Identify that AWS Local Zones extend the parent Region to place AWS resources physically closer to metropolitan areas, achieving single-digit millisecond latency.
Edge locations are for content caching (CDN) rather than full database deployment, whereas Local Zones support running compute and database workloads closer to local end-users.
3
Evaluate and eliminate incorrect infrastructure options.
Eliminate options claiming automatic cross-region replication, database hosting in Edge Locations, or cross-country distribution of Availability Zones within a single Region.
These claims misrepresent the role and capabilities of Edge Locations, Availability Zones, and the AWS Shared Responsibility Model.

An IoT company deploys telemetry collection servers on Amazon EC2 instances within a custom subnet. The cloud practitioner configures a Network Access Control List (Network ACL) at the subnet level to allow inbound TCP traffic on port 8883 from the internet. Although the EC2 instances' Security Groups are configured to allow all outbound traffic, the external sensors are unable to receive acknowledgment responses from the servers. Which of the following configuration changes is required to resolve this issue and allow the acknowledgment traffic back to the sensors?

Cevabı ve açıklamayı göster

Cevap: Add an outbound rule to the subnet's Network ACL that allows traffic to the ephemeral port range of the external sensors.

Cevap

Add an outbound rule to the subnet's Network ACL that allows traffic to the ephemeral port range of the external sensors.
The correct option is correct because Network ACLs are stateless firewalls operating at the subnet level. They evaluate inbound and outbound rules independently. When inbound traffic is allowed on port 8883, the return traffic destined for the client's ephemeral ports will be blocked unless an outbound rule explicitly allows it. Security Groups, on the other hand, are stateful and do not block this return traffic.

Analyze the network security configuration and traffic behavior.
The inbound traffic reaches the EC2 instances successfully, but the outbound return traffic is blocked at the subnet boundary.
Since the Security Group is stateful, it automatically permits return traffic. The failure must be occurring at the Network ACL, which controls subnet-level traffic.
2
Apply the rule characteristics of Network ACLs vs. Security Groups.
Network ACLs are stateless. Therefore, allowing inbound traffic on port 8883 does not automatically allow the outbound return traffic.
An explicit outbound rule must be configured in the Network ACL to allow the return traffic (typically using ephemeral ports) back to the client.

A boutique clothing retailer plans to launch a seasonal marketing campaign. Instead of purchasing physical servers and networking hardware to host their promotional website in a local data center, the retailer deploys the website on AWS to pay only for the virtual resources they consume during the campaign. Which benefit of the AWS Cloud is best illustrated by this scenario?

Cevap: Trade capital expense for variable expense

Cevap

Trade capital expense for variable expense
The correct answer is the cloud benefit that describes shifting upfront hardware costs (capital expenses) to pay-as-you-go costs based on consumption (variable expenses). By using AWS resources only for the duration of the campaign, the retailer avoids the capital costs of buying servers.

Adım Adım Çözüm

1
Analyze the financial transition in the scenario
The retailer avoids purchasing physical servers (upfront capital expense) and instead uses AWS on-demand resources (pay-as-you-go variable expense).
To identify which cloud benefit directly maps to the shift from upfront hardware investment to operational usage billing.
2
Map the result to the 6 core AWS Cloud benefits
The action of paying only for active virtual resources during the campaign aligns with trading capital expense for variable expense.
To select the official AWS benefit definition that represents this specific optimization.
