NEW QUESTION # 106
A company hosts its web application on AWS using seven Amazon EC2 instances. The company requires that the IP addresses of all healthy EC2 instances be returned in response to DNS queries.
Which policy should be used to meet this requirement?
Answer: D
Explanation:
Use a multivalue answer routing policy to help distribute DNS responses across multiple resources. For example, use multivalue answer routing when you want to associate your routing records with a Route 53 health check. For example, use multivalue answer routing when you need to return multiple values for a DNS query and route traffic to multiple IP addresses. https://aws.amazon.com/premiumsupport/knowledge-center/multivalue-versus-simple-policies/
NEW QUESTION # 107
A company needs to provide a team of contractors with temporary access to the company's AWS resources for a short-term project. The contractors need different levels of access to AWS services. The company needs to revoke permissions for all the contractors when the project is finished.
Which solution will meet these requirements with the LEAST operational overhead?
Answer: B
Explanation:
AWS STS issues temporary credentials with automatically expiring permissions based on IAM roles. This eliminates the need to manually manage or deactivate IAM users.
"You can use AWS STS to grant temporary security credentials that automatically expire after a specified duration."
- Temporary Security Credentials
This is the least operational overhead and follows AWS best practices for short-term access.
NEW QUESTION # 108
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?
Answer: A
Explanation:
As they would like to retrieve the data with sub-millisecond, DynamoDB with DAX is the answer.
DynamoDB supports some of the world's largest scale applications by providing consistent, single-digit millisecond response times at any scale. You can build applications with virtually unlimited throughput and storage.

NEW QUESTION # 109
A company has a mobile chat application with a data store based in Amazon uynamoUb. users would like new messages to be read with as little latency as possible A solutions architect needs to design an optimal solution that requires minimal application changes.
Which method should the solutions architect select?
Answer: C
Explanation:
Explanation
https://aws.amazon.com/premiumsupport/knowledge-center/dynamodb-high-latency/ Amazon DynamoDB Accelerator (DAX) is a fully managed in-memory cache for DynamoDB that improves the performance of DynamoDB tables by up to 10 times and provides microsecond level of response time at any scale. It is compatible with DynamoDB API operations and requires minimal code changes to use1. By configuring DAX for the new messages table, the solution can reduce the latency for reading new messages with minimal application changes.
B: Add DynamoDB read repticas to handle the increased read load. Update the application to point to the read endpoint for the read replicas. This solution will not work, as DynamoDB does not support read replicas as a feature. Read replicas are available for Amazon RDS, not for DynamoDB2.
C: Double the number of read capacity units for the new messages table in DynamoDB. Continue to use the existing DynamoDB endpoint. This solution will not meet the requirement of reading new messages with as little latency as possible, as increasing the read capacity units will only increase the throughput of DynamoDB, not the performance or latency3.
D: Add an Amazon ElastiCache for Redis cache to the application stack. Update the application to point to the Redis cache endpoint instead of DynamoDB. This solution will not meet the requirement of minimal application changes, as adding ElastiCache for Redis will require significant code changes to implement caching logic, such as querying cache first, updating cache after writing to DynamoDB, and invalidating cache when needed.

NEW QUESTION # 110
A company wants to use Amazon S3 to back up its on-premises file storage solution. The company's on-premises file storage solution supports NFS, and the company wants its new solution to support NFS. The company wants to archive the backup files after 5 days. If the company needs archived files for disaster recovery, the company is willing to wait a few days for the retrieval of those files. Which solution meets these requirements MOST cost-effectively?
Answer: C
Explanation:
S3 File Gateway is the right gateway type because the on-premises workload needsNFS-based file accesswhile storing data in Amazon S3. AWS documentation states that File Gateway exposes NFS and SMB shares backed by S3 objects. For the archive requirement, the company is willing to wait days for retrieval, which aligns withS3 Glacier Deep Archive, AWS's lowest-cost archival storage class for long-term retention. A lifecycle policy can transition the data automatically after 5 days. Volume Gateway is block-oriented, not NFS file-based, and Tape Gateway is intended for backup applications that use virtual tapes rather than standard NFS file shares. Therefore, File Gateway plus an S3 lifecycle transition to Glacier Deep Archive is the most cost-effective design.
