A voice rule uses Lowest Cost with load balancing disabled and a jitter SLA threshold of 15 ms. Members A (cost 5) and B (cost 50) are both routing eligible. A remains alive but its jitter rises to 25 ms; B still passes the SLA. Which member should this rule choose for new matching sessions?

Choose the single best answer.

A.The physical interface must immediately go down.
B.All traffic types must be blocked on A.
C.A fails the voice target, leaving B as the passing path.
D.A must stay preferred because its cost is lower.

Show the answer and explanation

✓ Correct answer

A fails the voice target, leaving B as the passing path.

Quality eligibility is evaluated before cost preference for this rule. An alive link can fail jitter without a physical outage. Other traffic or configured fallback can still use it; the voice result is not a blanket ban on the interface.
