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

✓

They are defined at the headend router with a destination and color.

SR-TE policies are stateful at the headend, use segment lists for path steering, and can be associated with a color for traffic engineering.

Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.

✓
They are defined at the headend router with a destination and color.
Why this is correct
Correct: Headend defines policy.
✓
They use explicit segment lists to encode the path.
Why this is correct
Correct: Segment lists define the path.
✗
They require RSVP-TE signaling to maintain state.
Why it's wrong here
SR-TE uses segment routing, not RSVP.
✓
They can be used to steer traffic onto a specific path for service-level agreement (SLA) compliance.
Why this is correct
Correct: SR-TE enables SLA-based traffic engineering.
✗
They require per-flow state at intermediate routers.
Why it's wrong here
Intermediate routers just forward based on labels; state only at headend.
