Use AWS Snowball to transfer a full backup, then manually apply transaction logs.

Answer

Set up a VPN connection and use Oracle GoldenGate for replication.

Answer

Export the database to flat files, upload to Amazon S3, and import into RDS.

Question 3

A company wants to modernize a legacy monolithic application by decomposing it into microservices. The application handles HTTP requests and uses a MySQL database. The company needs to decouple the microservices and improve scalability. Which AWS services should be used?

Accepted Answer

Amazon SQS for decoupling and Amazon Aurora MySQL for data.. Option C is correct because SQS decouples microservices and Aurora is a scalable MySQL-compatible database. Option A is wrong because S3 is not a queue. Option B is wrong because DynamoDB is NoSQL. Option D is wrong because Kinesis is for real-time streaming, not decoupling.

Answer

Amazon S3 for decoupling and Amazon RDS for MySQL.

Answer

Amazon SQS for decoupling and Amazon DynamoDB for data.

Answer

Amazon Kinesis Data Streams for decoupling and Amazon RDS for MySQL.

Question 4

A company is migrating a multi-tier web application to AWS. The application uses sticky sessions (session affinity). The company wants to use an Application Load Balancer (ALB). How should the architect configure the ALB to support sticky sessions?

Accepted Answer

Enable stickiness on the target group and set a cookie expiration duration.. Option D is correct because ALB supports sticky sessions by enabling stickiness on the target group and setting a duration. Option A is wrong because NLB does not support cookies for stickiness. Option B is wrong because stickiness is set on target group, not listener. Option C is wrong because stickiness is a feature of the load balancer, not an external service.

Answer

Configure the ALB listener to use a custom header for session affinity.

Answer

Use a Network Load Balancer (NLB) and enable proxy protocol.

Answer

Place an Amazon ElastiCache cluster in front of the ALB to store session data.

Question 5
