350-501 Architecture Practice Question
Exhibit
interface GigabitEthernet0/0/0 ip address 192.168.1.1 255.255.255.0 mpls ip mpls ldp autocfg
Refer to the exhibit. Which statement is true about this configuration?
⚠ Common exam trap
Cisco often tests the distinction between `mpls ip` (which enables LDP and MPLS forwarding) and manual LDP configuration (which would require `mpls ldp neighbor`), leading candidates to incorrectly assume that LDP requires explicit neighbor statements.
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
✓
LDP is automatically enabled on the interface
The `mpls ip` command under interface configuration enables LDP on that interface, allowing it to automatically discover LDP neighbors and exchange label bindings. This command implicitly enables LDP without requiring manual neighbor configuration, which is the default behavior for label distribution in many MPLS deployments.
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 is manually configured
Why it's wrong here
Autocfg means automatic, not manual.
- ✗
MPLS VPN is enabled
Why it's wrong here
These commands do not enable VPN; VRF configuration is needed.
- ✓
LDP is automatically enabled on the interface
Why this is correct
The autocfg command enables LDP automatically.
- ✗
MPLS forwarding is disabled
Why it's wrong here
'mpls ip' enables MPLS forwarding.
