1Z0-1072-26 Compute Practice Question
You are creating an instance configuration from an existing compute instance that has two secondary data block volumes attached in addition to its boot volume. What happens to the data block volumes when you use this instance configuration to create an instance pool?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Secondary block volumes are excluded from the instance pool configuration template; instance pools manage compute instances and boot volumes.
Instance configurations capture the instance metadata, shape, image, and boot volume settings. However, secondary block volume attachments are typically not cloned or automatically attached as independent writable block volumes for every new instance in the pool unless explicitly defined or managed via shared storage like File Storage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The instance pool creation fails because secondary block volumes are prohibited in instance pools.
Why it's wrong here
Creation does not fail, but secondary block volumes are not auto-cloned.
- ✗
The block volumes become shared network file systems across all pool members simultaneously in read-write mode.
Why it's wrong here
Block volumes cannot be attached in read-write mode to multiple instances simultaneously.
- ✗
Identical copies of the block volumes are automatically created and attached to every new instance in the pool.
Why it's wrong here
Instance pool instances do not automatically clone secondary block volumes for every member by default.
- ✓
Secondary block volumes are excluded from the instance pool configuration template; instance pools manage compute instances and boot volumes.
Why this is correct
Secondary block volume attachments are not part of standard instance pool creation templates.
