Refer to the graphic. R1 is unable to establish an OSPF neighbor relationship with R3. What are possible reasons for this problem? (Choose two.)
All of the routers need to be configured for backbone Area 1.
R1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3.
A static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established.
The hello and dead interval timers are not set to the same values on R1 and R3.
R1 and R3 are configured in different areas.

What is the effect when loopback interfaces and the configured router ID are absent during the OSPF Process configuration?
The lowest IP address is incremented by 1 and selected as the router ID.
The router ID 0.0.0.0 is selected and placed in the OSPF process.
No router ID is set, and the OSPF protocol does not run.
The highest up/up physical interface IP address is selected as the router ID.

When the active router in a VRRP group fails, which router assumes the role and forwards packets?
forwarding
standby
backup
listening
Which action does the router take as it forwards a packet through the network?
The router encapsulates the original packet and then includes a tag that identifies the source router MAC address and transmits it
transparently to the destination.
The router encapsulates the source and destination IP addresses with the sending router IP address as the source and the neighbor IP
address as the destination.
The router replaces the original source and destination MAC addresses with the sending router MAC address as the source and neighbor
MAC address as the destination.
The router replaces the source and destination labels with the sending router interface label as a source and the next hop router label as a
destination.
Refer to the exhibit. Which two prefixes are included in this routing table entry? (Choose two.)

Which virtual MAC address is used by VRRP group 1?
What is the purpose of using First Hop Redundancy Protocol on a specific subnet?
forwards multicast hello messages between routers
sends the default route to the hosts on a network
ensures a loop-free physical topology
filters traffic based on destination IP addressing

What is a benefit of VRRP?
It provides the default gateway redundancy on a LAN using two or more routers.
It provides traffic load balancing to destinations that are more than two hops from the source.
It prevents loops in a Layer 2 LAN by forwarding all traffic to a root bridge, which then makes the final forwarding decision.
It allows neighbors to share routing table information between each other.
