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
✓
The call is blocked
RSVP is a resource reservation protocol. If the path cannot support the required bandwidth, the call is rejected by the system.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The call is placed but with a lower quality codec
Why it's wrong here
RSVP does not automatically downgrade the codec during a failed reservation.
- ✗
The call is put on hold until bandwidth is available
Why it's wrong here
RSVP does not queue call requests.
- ✗
The call proceeds, but marks the packets with Best Effort
Why it's wrong here
RSVP enforcement prevents the call from proceeding rather than downgrading QoS.
- ✓
The call is blocked
Why this is correct
If resources cannot be reserved, the call attempt will be denied.
