Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
3600 seconds
Why this is correct
The default NHRP holdtime on Cisco routers is 3600 seconds, matching the stem's request for the default value. This timer governs how long a cached NHRP mapping stays valid before expiry, so 3600 seconds is the correct default figure.
- ✗
1800 seconds
Why it's wrong here
NHRP's default holdtime is 7200 seconds, so 1800 is wrong for this stem. The value is tempting because 1800 seconds matches HSRP's default holdtime, and it is a valid configurable NHRP holdtime via ip nhrp holdtime, but it is not the default.
- ✗
7200 seconds
Why it's wrong here
7200 seconds is not the default.
- ✗
600 seconds
Why it's wrong here
NHRP's default holdtime is 7200 seconds, not 600. The 600-second figure is tempting because it resembles short protocol timers such as IKE or routing hello intervals, and ip nhrp holdtime accepts it, but it is not the default value.
