A log-processing workload reads large files sequentially and prioritizes throughput. Which EBS volume type best matches this workload?

  1. A

    io2, because it is designed for intensive provisioned IOPS

  2. B

    st1, because it is designed for large sequential I/O

  3. C

    sc1, because it is a low-cost option for infrequently accessed data

  4. D

    gp2, because its performance scales with volume size and can burst

  1. A

    It is an option for supported io1 and io2 volumes.

  2. B

    It automatically coordinates concurrent writes from attached instances.

  3. C

    It requires compatible instances.

  1. A

    Detach the volume and attach it directly to an instance in the destination Availability Zone

  2. B

    Enable Multi-Attach and attach the volume to an instance in the destination Availability Zone

  3. C

    Create a snapshot, then create a volume from it in the destination Availability Zone

An EBS volume was created in one Availability Zone. Which instance can it attach to directly?

  1. A

    Attach it to any instance in the same AWS Region.

  2. B

    Attach it only to an instance in the same Availability Zone.

  3. C

    Attach it to an instance in another Availability Zone if the instance uses the same subnet.

  4. D

    Attach it to any instance after creating a snapshot.

You attach an EBS data volume to an EC2 instance, and you are not sure whether it already contains files. What is the safest next step?

  1. A

    Format the volume immediately, even if it might contain data.

  2. B

    Mount the volume without identifying the device or preparing it in the operating system.

  3. C

    Identify the device, create a file system only if needed, and mount it.

  4. D

    Create a snapshot before every mount, because snapshots are required for mounting.

A data-processing job reads large log files sequentially and prioritizes throughput. Which EBS volume type best matches this access pattern?

  1. A

    st1, because it is designed for large sequential I/O and throughput-oriented workloads.

  2. B

    io2, because it is designed for provisioned IOPS and intensive transactional I/O.

  3. C

    sc1, because it is designed for infrequently accessed data where storage cost is a priority.

  4. D

    gp2, because its performance scales with volume size and can burst.
