Correct answer & explanation

✓

Modify the EBS volume to increase its size while the instance is running, then extend the filesystem.

You can increase the size of an EBS volume while the instance is running, then extend the filesystem. Option A is correct. Option B is wrong because snapshots are for backup, not immediate space increase. Option C is wrong because reducing the volume size is not supported. Option D is wrong because creating a new volume and copying data requires downtime.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    Modify the EBS volume to increase its size while the instance is running, then extend the filesystem.

    Why this is correct

    EBS volumes can be increased online, and the filesystem can be extended without downtime.

  • ✗

    Reduce the size of the volume by modifying the volume configuration.

    Why it's wrong here

    EBS volume size cannot be reduced.

  • ✗

    Create a new larger EBS volume, attach it to the instance, and copy the data.

    Why it's wrong here

    Copying data while the system is running may cause inconsistencies.

  • ✗

    Create a snapshot of the volume and use it to create a larger volume, then attach and mount.

    Why it's wrong here

    This causes downtime during the migration.
