Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q239-Q244):NEW QUESTION # 239
A company currently stores 5 TB of data in on-premises block storage systems. The company's current storage solution provides limited space for additional data. The company runs applications on premises that must be able to retrieve frequently accessed data with low latency. The company requires a cloud-based storage solution.
Which solution will meet these requirements with the MOST operational efficiency?
A. Use Amazon S3 File Gateway Integrate S3 File Gateway with the on-premises applications to store and directly retrieve files by using the SMB file system.
B. Use an AWS Storage Gateway Volume Gateway with stored volumes as iSCSI targets.
C. Use an AWS Storage Gateway Tape Gateway. Integrate Tape Gateway with the on-premises applications to store virtual tapes in Amazon S3.
D. Use an AWS Storage Gateway Volume Gateway with cached volumes as iSCSt targets.
Answer: D
Explanation:
The company needs a cloud-based storage solution for frequently accessed data with low latency, while retaining their current on-premises infrastructure for some data storage. AWS Storage Gateway's Volume Gateway with cached volumes is the most appropriate solution for this scenario.
Detailed Explanation:
* AWS Storage Gateway - Volume Gateway (Cached Volumes):
* Volume Gateway with cached volumes allows you to store frequently accessed data in the AWS Cloud while keeping the most recently accessed data cached locally on-premises. This ensures low-latency access to active data while providing scalability for the rest of the data in the cloud.
* The cached volume option stores the primary data in Amazon S3 but caches frequently accessed data locally, ensuring fast access. This configuration is well-suited for applications that require fast access to frequently used data but can tolerate cloud-based storage for the rest.
* Since the company is facing limited on-premises storage, cached volumes provide an ideal solution, as they reduce the need for additional on-premises storage infrastructure.
* Why Not the Other Options?:
* Option A (S3 File Gateway): S3 File Gateway provides a file-based interface (SMB/NFS) for storing data directly in S3. While it is great for file storage, the company's need for block-level storage with iSCSI targets makes Volume Gateway a better fit.
* Option C (Volume Gateway - Stored Volumes): Stored volumes keep all the data on-premises and asynchronously back up to AWS. This would not address the company's storage limitations since they would still need substantial on-premises storage.
* Option D (Tape Gateway): Tape Gateway is designed for archiving and backup, not for frequently accessed low-latency data.

NEW QUESTION # 240
[Design Secure Architectures]
A company wants to share accounting data with an external auditor. The data is stored in an Amazon RDS DB instance that resides in a private subnet. The auditor has its own AWS account and requires its own copy of the database.
What is the MOST secure way for the company to share the database with the auditor?
A. Create an encrypted snapshot of the database. Share the snapshot with the auditor. Allow access to the AWS Key Management Service (AWS KMS) encryption key.
B. Copy a snapshot of the database to an Amazon S3 bucket. Create an IAM user. Share the user's keys with the auditor to grant access to the object in the $3 bucket.
C. Create a read replica of the database. Configure IAM standard database authentication to grant the auditor access.
D. Export the database contents to text files. Store the files in an Amazon S3 bucket. Create a new IAM user for the auditor. Grant the user access to the S3 bucket.
Answer: A
Explanation:
This answer is correct because it meets the requirements of sharing the database with the auditor in a secure way. You can create an encrypted snapshot of the database by using AWS Key Management Service (AWS KMS) to encrypt the snapshot with a customer managed key. You can share the snapshot with the auditor by modifying the permissions of the snapshot and specifying the AWS account ID of the auditor. You can also allow access to the AWS KMS encryption key by adding a key policy statement that grants permissions to the auditor's account. This way, you can ensure that only the auditor can access and restore the snapshot in their own AWS account.

NEW QUESTION # 241
A company hosts a multiplayer gaming application on AWS. The company wants the application to read data with sub-millisecond latency and run one-time queries on historical data.
Which solution will meet these requirements with the LEAST operational overhead?
A. Use Amazon RDS for data that is frequently accessed. Run a periodic custom script to export the data to an Amazon S3 bucket.
B. Use Amazon DynamoDB for data that is frequently accessed Turn on streaming to Amazon Kinesis Data Streams. Use Amazon Kinesis Data Firehose to read the data from Kinesis Data Streams. Store the records in an Amazon S3 bucket.
C. Store the data directly in an Amazon S3 bucket. Implement an S3 Lifecycle policy to move older data to S3 Glacier Deep Archive for long-term storage. Run one-time queries on the data in Amazon S3 by using Amazon Athena
D. Use Amazon DynamoDB with DynamoDB Accelerator (DAX) for data that is frequently accessed. Export the data to an Amazon S3 bucket by using DynamoDB table export. Run one-time queries on the data in Amazon S3 by using Amazon Athena.
Answer: D
NEW QUESTION # 242
A company is running a batch application on Amazon EC2 instances. The application consists of a backend with multiple Amazon RDS databases. The application is causing a high number of leads on the databases. A solutions architect must reduce the number of database reads while ensuring high availability.
What should the solutions architect do to meet this requirement?
A. Use Amazon ElastCache for Redis
B. Use Amazon ElastiCache for Memcached
C. Use Amazon Route 53 DNS caching
D. Add Amazon RDS read replicas
Answer: D
Explanation:
Explanation
This solution meets the requirement of reducing the number of database reads while ensuring high availability for a batch application that consists of a backend with multiple Amazon RDS databases. Amazon RDS read replicas are copies of the primary database instance that can serve read-only traffic. You can create one or more read replicas for a primary database instance and connect to them using a special endpoint. Read replicas can improve the performance and availability of your application by offloading read queries from the primary database instance.
Option B is incorrect because using Amazon ElastiCache for Redis can provide a fast, in-memory data store that can cache frequently accessed data, but it does not support replication from Amazon RDS databases.
Option C is incorrect because using Amazon Route 53 DNS caching can improve the performance and availability of DNS queries, but it does not reduce the number of database reads. Option D is incorrect because using Amazon ElastiCache for Memcached can provide a fast, in-memory data store that can cache frequently accessed data, but it does not support replication from Amazon RDS databases.

NEW QUESTION # 243
A company runs a containerised application on a Kubernetes cluster m an on premises data center The company is using a MongoOB drtabii tor dan atanige The company wants to migrate some of these environments to AWS but no code changes or deployment method changes ate possible at this time The company needs a solution mat minimizes operational overhead Which solution meets these requirements?
A. Use Amazon Elastic Kubernetes Service (Amazon EKS) with AWS fargate for compute and Amazon DocumentDB (with MongoOB compatfciMy) for data storage
B. Use Amazon Elastic Kubernetes Service (Amazon EKS) with Amazon EC2 worker nodes for compute and Amazon DynamoDB for data storage
C. Use Amazon Elastic Container Service (Amazon ECS) with Amazon EC2 worker nodes for compute and MongoOB on EC2 for data storage
D. Use Amazon Elastic Container Service (Amazon ECS) with AWS Fargate for compute and Amazon DynamoDB tor data storage
Answer: A
Explanation:
Amazon DocumentDB (with MongoDB compatibility) is a fast, reliable, and fully managed database service. Amazon DocumentDB makes it easy to set up, operate, and scale MongoDB-compatible databases in the cloud. With Amazon DocumentDB, you can run the same application code and use the same drivers and tools that you use with MongoDB. https://docs.aws.amazon.com/docu ... rguide/what-is.html
