350-401 Practice Question: The default update interval for a Cisco IOS-XE…
What is the default update interval for a Cisco IOS-XE telemetry subscription when using update-policy periodic without specifying a value?

Why each option matters

Correct answer & explanation
✓
10000 milliseconds
The default periodic interval is 10000 milliseconds (10 seconds) if not explicitly configured.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
1000 milliseconds
Why it's wrong here
The default periodic interval on IOS-XE telemetry is 30000 milliseconds, not 1000. A one-second cadence is tempting because it matches the fastest practical polling rate for near-real-time monitoring, and would be chosen when sub-second visibility of interface counters is genuinely required.
- ✓
10000 milliseconds
Why this is correct
Omitting the value in an update-policy periodic subscription applies the platform default of 10000 milliseconds, satisfying the stem's unspecified-interval constraint. IOS-XE telemetry therefore pushes updates every ten seconds without explicit configuration, matching the documented default rather than a user-defined cadence.
- ✗
5000 milliseconds
Why it's wrong here
IOS-XE defaults the periodic update policy to 30000 milliseconds, so 5000 fails this scenario. Five seconds is tempting as it mirrors common SNMP polling intervals, and would be correct when balancing telemetry granularity against CPU and bandwidth overhead on a busy device.
- ✗
The command requires a value; there is no default.
Why it's wrong here
Periodic update-policy does accept a default interval when no value is supplied, so claiming the command requires one is false. It is tempting because many IOS-XE commands mandate explicit arguments, but the actual default is 30 seconds, which the subscription applies automatically.
