Question 1

A company is migrating a legacy application to AWS. The application runs on Windows Server and uses a shared file system for storage. The company wants to modernize the application by using a managed file storage service that is POSIX-compliant and can be accessed by multiple EC2 instances concurrently. Which TWO AWS services meet these requirements? (Choose TWO.)

Accepted Answer

Amazon FSx for Lustre. Option B (Amazon EFS) and Option D (Amazon FSx for Lustre) are both POSIX-compliant file systems that can be accessed concurrently by multiple EC2 instances. Option A (Amazon S3) is object storage, not POSIX-compliant. Option C (Amazon EBS) is block storage that can be attached to one instance at a time (unless using multi-attach, but that is limited). Option E (Amazon S3 Glacier) is archival storage.

Answer

I3

Question 8

A company is migrating a legacy application that uses TCP on port 8080 to AWS. The application must be accessible from the internet. The company wants to use an Application Load Balancer. What must the company do to ensure the load balancer can accept traffic on port 8080?

Accepted Answer

Create a listener for port 8080 on the ALB.. Option D is correct because ALB supports custom ports; you create a listener for port 8080. Option A is wrong because ALB does not require a specific security group port; you can configure any port. Option B is wrong because you cannot change the ALB's default ports; you add a listener. Option C is wrong because ALB itself does not need a public IP; it uses a DNS name.

Answer

Configure the security group to allow inbound traffic on port 80 and 443 only.

Answer

Change the ALB's default port to 8080.

Answer

Assign an Elastic IP address to the ALB.

Question 9

A company is migrating a web application to AWS and wants to use Amazon ECS with Fargate. The application needs to store session state. Which AWS service should the company use for session state management?

Accepted Answer

Amazon ElastiCache for Redis. Option B is correct because Amazon ElastiCache for Redis is commonly used for session state management in containerized applications. Option A is wrong because Amazon DynamoDB can also be used, but ElastiCache is more commonly recommended for session state. Option C is wrong because Amazon S3 is not suitable for low-latency session state. Option D is wrong because Amazon RDS is for relational databases, not session state.

Answer

Amazon S3

Answer

Amazon DynamoDB

Answer

Question 11

A company is migrating a critical application to AWS and needs to ensure it meets a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 5 minutes. The application runs on EC2 with an EBS volume. Which configuration should the company use?

Accepted Answer

Multi-AZ deployment with synchronous replication between two instances.. Option D is correct because Multi-AZ with synchronous replication provides low RTO and RPO. Option A is wrong because a single EC2 instance does not provide failover. Option B is wrong because EBS Snapshots have higher RPO. Option C is wrong because an Auto Scaling group alone does not handle stateful recovery.

Answer

Single EC2 instance with EBS snapshots every 5 minutes.

Answer

Two EC2 instances in an Auto Scaling group with a warm standby.

Answer

EC2 instance with Elastic Disaster Recovery service.

Question 12
