Assume that there are four flows a, b, c, and d, the transmission rate of each flow is 50 Mbit/s, and the total bandwidth of the interface for flow transmission is 100 Mbit/s. In the case of congestion, PQ is available for flow a. WFQ is available for flows b, c, and d, with the weight proportion being 1:2:3:4. Which of the following statement about the interface bandwidth allocated to each flow is true? (Choose two.)

The interface bandwidth allocated to flow a is 100 Mbit/s.

The interface bandwidth allocated to flow a is 50 Mbit/s.

The interface bandwidth allocated to flows b is 10 Mbit/s and interface bandwidths allocated to flows c and d are 20 Mbit/s each.

The interface bandwidth allocated to flows b is 25 Mbit/s and interface bandwidths allocated to flows c and d are 12.5 Mbit/s each.

Question 233

Which of the following statements about the VRRP working process is false?

The router with the highest priority is elected as the master router.

The master router sends gratuitous ARP packets to inform connected devices or hosts of its virtual MAC address.

If the master router fails, the backup router with the highest priority is elected as the new master router.

To ensure fast convergence, a backup router immediately becomes the master router if the priority of the backup router is higher than the priority of the master router.

True

False

Question 239

Which of the following statements about the jitter and delay are true? (Choose three.)

The end-to-end delay is the sum of transmission delays, processing delays, and queuing delays along the packet forwarding path.

The variation in packet delay is called jitter.

The jitter depends on the delay. The lower the delay, the less the jitter.

The jitter is independent of the delay.

Packet A is scheduled first.

Packet B is scheduled first.

Packets A and B are scheduled at the same time.

Packets A and B are discarded.
