Question 55

A solutions architect is launching an Amazon EC2 instance with multiple attached volumes by modifying the block device mapping. Which block device can be specified in a block device mapping to be used with an EC2 instance? (Select TWO)

1. EBS volume
2. EFS volume
3. Instance store volume
4. Snapshot
5. S3 bucket

Correct Answer: 1, 3

Explanation: Each instance that you launch has an associated root device volume, either an Amazon EBS volume or an instance store volume.

You can use block device mapping to specify additional EBS volumes or instance store volumes to attach to an instance when it’s launched. You can also attach additional EBS volumes to a running instance.

You cannot use a block device mapping to specify a snapshot, EFS volume, or S3 bucket.

CORRECT: “EBS volume” is a correct answer.

INCORRECT: “EFS volume” is incorrect as described above.

CORRECT: “Instance store volume” is also a correct answer.

INCORRECT: “Snapshot” is incorrect as described above.

INCORRECT: “S3 bucket” is incorrect as described above.
