350-501 Architecture Practice Question
Which THREE are benefits of implementing MPLS-TE in a service provider core?
⚠ Common exam trap
Cisco often tests the misconception that MPLS-TE reduces routing table size or natively supports multicast, but these are not inherent benefits of the technology.
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
✓
Ability to guarantee bandwidth for specific traffic flows
MPLS-TE allows operators to reserve bandwidth along explicit paths using RSVP-TE signaling, ensuring that specific traffic flows receive guaranteed bandwidth. This is achieved through bandwidth reservation and admission control, which prevents oversubscription on TE tunnels.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reduction in BGP routing table size
Why it's wrong here
BGP table size is unaffected by MPLS-TE.
- ✓
Ability to guarantee bandwidth for specific traffic flows
Why this is correct
TE tunnels can be provisioned with bandwidth reservations.
- ✓
Load balancing across multiple paths
Why this is correct
TE can distribute traffic over multiple paths.
- ✓
Fast restoration using Fast Reroute (FRR)
Why this is correct
FRR provides sub-50ms protection.
- ✗
Native support for multicast
Why it's wrong here
MPLS-TE requires multicast extensions; not native.
