Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q1085-Q1090):

NEW QUESTION # 1085
[Design High-Performing Architectures]
A company has a business-critical application that runs on Amazon EC2 instances. The application stores data in an Amazon DynamoDB table. The company must be able to revert the table to any point within the last 24 hours.
Which solution meets these requirements with the LEAST operational overhead?

  • A. Use AWS Backup for the table.
  • B. Use an AWS Lambda function to make an on-demand backup of the table every hour.
  • C. Configure point-in-time recovery for the table.
  • D. Turn on streams on the table to capture a log of all changes to the table in the last 24 hours Store a copy of the stream in an Amazon S3 bucket.

Answer: C

Explanation:
Point-in-time recovery (PITR) for DynamoDB is a feature that enables you to restore your table data to any point in time during the last 35 days. PITR helps protect your table from accidental write or delete operations, such as a test script writing to a production table or a user issuing a wrong command. PITR is easy to use, fully managed, fast, and scalable. You can enable PITR with a single click in the DynamoDB console or with a simple API call. You can restore a table to a new table using the console, the AWS CLI, or the DynamoDB API. PITR does not consume any provisioned table capacity and has no impact on the performance or availability of your production applications. PITR meets the requirements of the company with the least operationaloverhead, as it does not require any manual backup creation, scheduling, or maintenance. It also provides per-second granularity for restoring the table to any point within the last 24 hours.

NEW QUESTION # 1086
A company is creating an application The company stores data from tests of the application in multiple on-premises locations The company needs to connect the on-premises locations to VPCs in an AWS Region in the AWS Cloud The number of accounts and VPCs will increase during the next year The network architecture must simplify the administration of new connections and must provide the ability to scale.
Which solution will meet these requirements with the LEAST administrative overhead'?

  • A. Create an AWS Direct Connect connection between the on-premises locations and a central VPC. Connect the central VPC to other VPCs by using peering connections.
  • B. Create a transit gateway Create VPC attachments for the VPC connections Create VPN attachments for the on-premises connections.
  • C. Launch an Amazon EC2 instance On the instance, include VPN software that uses a VPN connection to connect all VPCs and on-premises locations.
  • D. Create a peering connection between the VPCs Create a VPN connection between the VPCs and the on-premises locations.

Answer: B

Explanation:
A transit gateway is a network transit hub that enables you to connect your VPCs and on-premises networks in a centralized and scalable way. You can create VPC attachments to connect your VPCs to the transit gateway, and VPN attachments to connect your on-premises networks to the transit gateway over the internet. The transit gateway acts as a router between the attached networks, and simplifies the administration of new connections by reducing the number of peering or VPN connections required. You can also use transit gateway route tables to control the routing of traffic between the attached networks. By creating a transit gateway and using VPC and VPN attachments, you can meet the requirements of the company with the least administrative overhead.

NEW QUESTION # 1087
[Design Secure Architectures]
A developer needs to export the contents of several Amazon DynamoDB tables into Amazon S3 buckets to comply with company data regulations. The developer uses the AWS CLI to runcommands to export from each table to the proper S3 bucket. The developer sets up AWS credentials correctly and grants resources appropriate permissions. However, the exports of some tables fail.
What should the developer do to resolve this issue?

  • A. Ensure that DynamoDB streaming is enabled for the tables.
  • B. Ensure that point-in-time recovery is enabled on the DynamoDB tables.
  • C. Ensure that the target S3 bucket is in the same AWS Region as the DynamoDB table.
  • D. Ensure that DynamoDB Accelerator (DAX) is enabled.

Answer: B

Explanation:
Export Requirements:
To export data from DynamoDB to Amazon S3, point-in-time recovery (PITR) must be enabled for the tables. This feature creates a snapshot of the data, which is essential for exports.
Incorrect Options Analysis:
Option B: S3 buckets and DynamoDB tables do not need to be in the same region for exports.
Option C: DynamoDB streams are unrelated to the export functionality.
Option D: DAX accelerates reads but has no role in exports.

NEW QUESTION # 1088
A company will deployed a web application on AWS. The company hosts the backend database on Amazon RDS for MySQL with a primary DB instance and five read replicas to support scaling needs. The read replicas must log no more than 1 second bahind the primary DB Instance. The database routinely runs scheduled stored procedures.
As traffic on the website increases, the replicas experinces addtional lag during periods of peak lead. A solutions architect must reduce the replication lag as much as possible. The solutions architect must minimize changes to the applicatin code and must minimize ongoing overhead.
Which solution will meet these requirements?
Migrate the database to Amazon Aurora MySQL. Replace the read replicas with Aurora Replicas, and configure Aurora Auto Scaling. Replace the stored procedures with Aurora MySQL native functions.
Deploy an Amazon ElasticCache for Redis cluser in front of the database. Modify the application to check the cache before the application queries the database. Repace the stored procedures with AWS Lambda funcions.

  • A. Migrate the database to a MYSQL database that runs on Amazn EC2 instances. Choose large, compute optimized for all replica nodes. Maintain the stored procedures on the EC2 instances.
  • B. Migrate the database to Amazon DynamoDB, Provision number of read capacity units (RCUs) to support the required throughput, and configure on-demand capacity scaling. Replace the stored procedures with DynamoDB streams.
  • C. Deploy an Amazon ElastiCache for Redis cluster in fornt of the database. Modify the application to check the cache before the application queries the database. Replace the stored procedures with AWS Lambda functions.
  • D. Migrate the database to a MySQL database that runs on Amazon EC2 instances. Choose large, compute optimized EC2 instances for all replica nodes, Maintain the stored procedures on the EC2 instances.

Answer: A

Explanation:
Explanation
Option A is the most appropriate solution for reducing replication lag without significant changes to the application code and minimizing ongoing operational overhead. Migrating the database to Amazon Aurora MySQL allows for improved replication performance and higher scalability compared to Amazon RDS for MySQL. Aurora Replicas provide faster replication, reducing the replication lag, and Aurora Auto Scaling ensures that there are enough Aurora Replicas to handle the incoming traffic. Additionally, Aurora MySQL native functions can replace the stored procedures, reducing the load on the database and improving performance.


NEW QUESTION # 1089
A company runs an application on Amazon EC2 Instances in a private subnet. The application needs to store and retrieve data in Amazon S3 buckets. According to regulatory requirements, the data must not travel across the public internet.
What should a solutions architect do to meet these requirements MOST cost-effectively?

  • A. Deploy a NAT gateway to access the S3 buckets.
  • B. Deploy an S3 interface endpoint to access the S3 buckets.
  • C. Deploy an S3 gateway endpoint to access the S3 buckets.
  • D. Deploy AWS Storage Gateway to access the S3 buckets.

Answer: C

Explanation:
* Understanding the Requirement: The application running in a private subnet needs to store and retrieve data from S3 without data traveling over the public internet.
* Analysis of Options:
* NAT Gateway: Allows private subnets to access the internet but incurs additional costs and still routes traffic through the public internet.
* AWS Storage Gateway: Provides hybrid cloud storage solutions but is not the most cost-effective for direct S3 access from within the VPC.
* S3 Interface Endpoint: Provides private access to S3 but is generally used for specific use cases
* where more granular control is required, which might be overkill and more expensive.
* S3 Gateway Endpoint: Provides private, cost-effective access to S3 from within the VPC without routing traffic through the public internet.
* Best Solution:
* S3 Gateway Endpoint: This option meets the requirements for secure, private access to S3 from a private subnet most cost-effectively.
References:
* Amazon VPC Endpoints
* Gateway Endpoints
