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, WFQ is available for flows a, 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?

Interface bandwidths allocated to flows a, b, c, and d are 10 Mbit/s, 20 Mbit/s, 30 Mbit/s, and 40 Mbit/s respectively.

Interface bandwidths allocated to flows a, b, c, and d are 50 Mbit/s, 50 Mbit/s, 0 Mbit/s, and 0 Mbit/s respectively.

Interface bandwidths allocated to flows a, b, c, and d are 40 Mbit/s, 30 Mbit/s, 20 Mbit/s, and 10 Mbit/s respectively.

Flows a, b, c, and d are discarded.

Which of the following statements are correct regarding MAC address of VRRP packet? (Choose two.)

The destination MAC is multicast MAC address.

The source address is virtual MAC address.

The destination MAC is broadcast MAC address.

The destination MAC is multicast MAC address.

The source address is virtual MAC address.

The source address is physical MAC address of Master.

Which of the following statements about the refreshing mechanism in the case of link switchover in a Smart Link group is false?

When the active link recovers from a fault, Flush packets are sent to refresh entries.

MAC and ARP entries are refreshed automatically against traffic.

The Smart Link group uses a new link to send Flush packets.

When the active link recovers from a fault, Flush packets are sent to refresh entries.

When recovering from a fault, the active link remains blocked and traffic is not switched back to it. In this way, traffic keeps stable.

Assume that the WRED policy for packets with the priority of AF21 is that the length of the queue for saving packets ranges from 35 to 40, and the discarding percentage is 50%. When a packet with the priority being AF21 arrives, which of the following statements are true? (Choose three.)

If the average length of the queue is smaller than 35, the packet is added to the queue.

If the length of the queue ranges between 35 and 40, the packet may be discarded with a possibility of 50%.

If the average length of the queue is greater than 40, the packet is discarded.

If the average length of the queue is smaller than 35, the packet is added to the queue.

If the length of the queue ranges between 35 and 40, the packet may be discarded with a possibility of 50%.

If the average length of the queue is greater than 40, the packet is added to the queue.

If the average length of the queue is greater than 40, the packet is discarded.

Which of the following statements are correct regarding the function of VRRP?

VRRP can improve the reliability of default gateway.

VRRP increase the convergence speed of routing protocol.

VRRP is mainly used for traffic balance.

VRRP can provide one default gateway for different network segments, it simplifies the gateway configuration for PC.

Which of the following statements are correct regarding priority in VRRP?

The IP address owner always uses 255 as its priority regardless its config priority.

The IP address owner always uses 0 as its priority regardless its config priority.

We can configure the priority as 0 to make the router never attend the Master election.

If a VRRP router changes from Master to Slave, it will send out a VRRP message with priority 0 in the network.

Which of the following statements about a backup router in a VRRP backup group are true? (Choose three.)

It receives VRRP packets from the master router and determines whether the master router is functioning properly.

It does not respond to the ARP requests sent from a virtual IP address.

It discards an IP packet whose destination IP address is a virtual IP address.

It receives VRRP packets from the master router and determines whether the master router is functioning properly.

It does not respond to the ARP requests sent from a virtual IP address.

It forwards an IP packet whose destination MAC address is a virtual MAC address.

It discards an IP packet whose destination IP address is a virtual IP address.

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 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 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.

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

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.

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.

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 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.
