Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Block volume performance can be scaled independently of storage capacity by adjusting Volume Performance Units (VPUs).
Why this is correct
Users can select different performance tiers or adjust VPUs to scale IOPS and throughput.
- ✗
Block volumes can only be attached to a single compute instance across multiple regions simultaneously.
Why it's wrong here
Block volumes cannot be attached across multiple regions; cross-region requires replication or backups.
- ✗
Block volume backups are always full backups and incremental backups are not supported.
Why it's wrong here
OCI Block Volume supports both full and incremental backups.
- ✓
Block volume backups can be copied across different OCI regions.
Why this is correct
Cross-region backup copying is supported for disaster recovery.
- ✓
You can resize a block volume online without detaching it from the compute instance.
Why this is correct
Online resizing allows increasing volume capacity without rebooting or detaching the instance.
