350-401 Practice Question: Runs the following command on Router R7: R7# show…
A network engineer runs the following command on Router R7:
R7# show mpls ldp capabilities
LDP Capabilities: Dynamic Capability: advertised Typed Wildcard FEC: advertised MTU Signaling: advertised P2MP: not advertised MPLS OAM: advertised LDP Graceful Restart: advertised Helper mode: enabled Restart mode: enabled Reconnect time: 120 sec Recovery time: 180 sec
Based on this output, which capability is NOT supported by this router?
⚠ Common exam trap
Cisco often tests the ability to read the 'show mpls ldp capabilities' output literally, where the trap is that candidates assume all capabilities are supported by default or confuse 'not advertised' with a misconfiguration rather than a lack of feature support.
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
✓
P2MP (Point-to-Multipoint)
The output shows 'P2MP: not advertised', which explicitly indicates that Point-to-Multipoint (P2MP) capability is not supported on this router. All other listed capabilities, including LDP Graceful Restart, MTU Signaling, and Dynamic Capability, are shown as 'advertised' and therefore supported.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
LDP Graceful Restart
Why it's wrong here
LDP Graceful Restart is advertised with helper and restart modes enabled, plus reconnect and recovery timers, so it is supported. P2MP is the sole capability marked "not advertised"; Graceful Restart would be the answer if its line showed "not advertised".
- ✗
MTU Signaling
Why it's wrong here
MTU Signaling is listed as advertised, so it is supported. The output's only "not advertised" entry is P2MP, which is the capability genuinely absent; MTU Signaling would be the answer only if the line read "not advertised".
- ✓
P2MP (Point-to-Multipoint)
Why this is correct
The output lists P2MP as "not advertised", meaning the router does not signal Point-to-Multipoint LDP capability to its peers. Every other capability shown, including Typed Wildcard FEC and LDP Graceful Restart, is advertised, isolating P2MP as the unsupported one.
- ✗
Dynamic Capability
Why it's wrong here
Dynamic Capability is advertised, so the router supports it. Only P2MP carries "not advertised" in this output, making it the unsupported capability; Dynamic Capability would be correct only if its status line read "not advertised".
