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 backup data was not encrypted.
Why it's wrong here
Encryption affects data security, not network configuration.
- ✗
The test was not conducted during business hours.
Why it's wrong here
Timing of the test does not cause configuration mismatch.
- ✓
The DR plan was not updated to reflect production changes.
Why this is correct
Changes in production should be replicated to the hot site; otherwise, incompatibility occurs.
- ✗
The hot site is too far from the primary site.
Why it's wrong here
Distance affects latency, not configuration compatibility.
