CLCOR Infrastructure And Design Practice Question
When designing an NTP deployment for a Cisco Collaboration environment, what is the best practice for time synchronization across CUCM nodes?
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
✓
Point all CUCM nodes to the same external NTP stratum 1 or 2 servers.
CUCM nodes must point to the same reliable external Stratum 1 or 2 NTP servers to ensure call logs and security certificates remain synchronized.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Point all CUCM nodes to the same external NTP stratum 1 or 2 servers.
Why this is correct
Consistency is vital to prevent database replication failures.
- ✗
Configure NTP only on the publisher node.
Why it's wrong here
All nodes require direct synchronization to a master time source.
- ✗
Point each CUCM node to a different NTP server for redundancy.
Why it's wrong here
This leads to time drift between nodes, causing database errors.
- ✗
Use the publisher as the NTP server for all subscriber nodes.
Why it's wrong here
While possible, it creates a single point of failure and lacks external stratum accuracy.
