VRRP does not support preemption.
VRRP cannot track interfaces or objects.
A VRRP group has one master router and one or more backup routers.
The virtual IP address for the VRRP group must be different from active and standby IP addresses.
VRRP provides redundancy for the IP address of a router or for a virtual IP address shared among the VRRP group members.
A VRRP group has one master router and one or more backup routers.
VRRP provides redundancy for the IP address of a router or for a virtual IP address shared among the VRRP group members.
Which one of the following GLBP functions answers ARP requests?
AVF
AVG
Active
MVP
AVG
What are two functions of the standby router in an HSRP group? (Choose two.)
to monitor the operational status of the HSRP group
to physically forward packets that are sent to the MAC address of the virtual router
to reply with the virtual router MAC address in the event an ARP request is received
to quickly assume packet-forwarding responsibility if the active router becomes inoperable
to contend for the active router role with all other routers in the group in the event the active fails
to monitor the operational status of the HSRP group
to quickly assume packet-forwarding responsibility if the active router becomes inoperable
Refer to the exhibit. What action does the command standby 1 track Serial0/0/0 on router R1 perform?
It links the default gateway virtual address 192.168.21.10 to the IP address 192.168.31.1 on interface Serial0/0/0.
It links the default gateway virtual address 192.168.21.10 to the IP address 192.168.42.2 on interface Serial0/0/0.
It tracks the state of the Fa0/0 interface on R1 and brings down the priority of standby group 1 if the interface goes down.
It tracks the state of the Serial0/0/0 interface on R1 and brings down the priority of standby group 1 if the interface goes down.
It tracks the state of the Serial0/0/0 interface on R1 and brings down the priority of standby group 1 if the interface goes down.
Which statement is true about the gateway redundancy protocols ?
GLBP allows multiple routers to participate in a virtual router group that is configured with a virtual IP address. One member is elected to be the active router for the group and the other routers are passive until the active router fails.
By making use of a single virtual IP address and multiple virtual MAC addresses, GLBP provides load balancing over multiple routers (gateways) . All routers in the virtual router group participate in forwarding packets.
By making use of a single virtual IP address and multiple virtual MAC addresses, HSRP provides load balancing over multiple routers (gateways). All routers in the virtual router group participate in forwarding packets.
By making use of a single virtual IP address and multiple virtual MAC addresses, VRRP provides load balancing over multiple routers (gateways). All routers in the virtual router group participate in forwarding packets.
By making use of a single virtual IP address and multiple virtual MAC addresses, GLBP provides load balancing over multiple routers (gateways) . All routers in the virtual router group participate in forwarding packets.
Refer to the exhibit. Based on the provided configuration, which routers are the master and the backup virtual routers for the hosts that are connected to the VRRP group 1?
Router R1 is the master for all hosts, and router R2 is the backup for all hosts in the group.
Router R1 is the master for Host1 and Host2. Router R2 is the master for Host3 and Host4.
Router R1 is the master for Host3 and Host4. Router R2 is the backup for Host3 and Host4.
Because of incorrect configuration of the default gateway on the hosts, none of the routers is the master for the VRRP group.
Router R1 is the master for Host1 and Host2. Router R2 is the master for Host3 and Host4.
Two routers are configured for an HSRP group. One router uses the default HSRP priority. What priority should be assigned to the other router to make it more likely to be the active router?
1
100
200
500
200
Refer to the exhibit. Which statement is true about best practice and the exhibited network design?
The Layer 2 VLAN number should be mapped to the Layer 3 subnet for ease of use and management.
The HSRP active router for VLAN 55 and VLAN 60 should be the same switch.
A Layer 2 access port should be placed between the access switches.
The uplink between the access switches and the distribution switches should be trunk links.
The Layer 2 VLAN number should be mapped to the Layer 3 subnet for ease of use and management.
What are two characteristics of Gateway Load Balancing Protocol (GLBP) operation? (Choose two.)
GLBP will attempt to balance traffic on a per-router basis by the use of the round-robin algorithm.
GLBP will attempt to balance traffic on a per-host basis by the use of the round-robin algorithm.
The active virtual forwarder (AVF) is assigned a virtual MAC address and forwards packets sent to that MAC address.
The active virtual gateway (AVG) is the backup for the AVF.
GLBP members communicate with each other through hello messages sent every 3 seconds to the multicast address 224.0.0.104.
GLBP will attempt to balance traffic on a per-host basis by the use of the round-robin algorithm.
The active virtual forwarder (AVF) is assigned a virtual MAC address and forwards packets sent to that MAC address.
