ACSP Virtual Router Redundancy (VRRP) 4

Question 1

A network administrator wants to use two VRRP groups on the same VLAN to achieve load balancing. How is this accomplished?

Accepted Answer

Create two VRRP groups with different VRIDs; make each router master of one group

Answer

Load balancing with VRRP is achieved by running two VRRP groups with different VRIDs, configuring each router as master of one group, and splitting hosts between the two virtual gateways.

Question 2

Which multicast address does VRRPv2 use to send advertisement messages?

Accepted Answer

224.0.0.18

Answer

VRRPv2 sends advertisement packets to the multicast group 224.0.0.18 using IP protocol number 112.

Question 3

On an Aruba switch, which of the following is the correct sequence to add VRRP tracking for an uplink interface?

Accepted Answer

Define track object → apply track object to VRRP group with priority decrement

Answer

The correct process is to first define the tracking object (e.g., track interface or IP SLA), then reference it in the VRRP group configuration with a priority decrement value.

Question 4

What IP protocol number is used by VRRP packets?

Accepted Answer

112

Answer

VRRP uses IP protocol number 112, which identifies VRRP packets at the network layer.

Question 5

In a VRRP deployment on Aruba switches, what is the effect of configuring a very short advertisement interval?

Accepted Answer

It reduces the master-down interval, enabling faster failover detection

Answer

A shorter advertisement interval reduces the master-down timer calculation, allowing backup routers to detect master failure more quickly and take over faster.
