Routing CCNA questions

Which 2 minimum parameters must be configured on an active interface to enable OSPFv2 to operate? (Choose two.)

• OSPF area

• OSPF MD5 authentication key

• IPv6 address

• OSPF process ID

• OSPF stub flag

R5 and R4 currently have flapping interfaces and the engineer wants OSPF to elect a different DR/BDR. Which set of configurations would help?

• R4 - int g0/0 > ip ospf priority 20

  R5 - int g0/0 > ip ospf priority 10

• R2 - int g0/0 > ip ospf priority 259

  R3 - int g0/0 > ip ospf priority 256

• R5 - int g0/0 > ip ospf priority 120

  R4 - int g0/0 > ip ospf priority 110

• R3 - int g0/0 > ip ospf priority 255

  R2 - int g0/0 > ip ospf priority 240

A router reserved these 5 routes from different routing information sources. Which 2 routes does the router install in its routing table? (Choose two.)

• RIP route

• iBGP route

• OSPF route 10.0.0.0/30

• EIGRP route

• OSPF route 10.0.0.0/16

If OSPF is running on this network, how does R2 handle traffic from Site B to 10.10.13.128/25 at Site A?

• It load-balances traffic out of Fa0/1 and Fa0/2

• It is unreachable and discards the traffic.

• It sends packets out of interface fa0/2

• It sends packets out of interface fa0/1

What action does the router take as it forwards a packet through the network?

• The router replaces the original source and destination MAC address with the sending router MAC address as the source and neighbor MAC address as the destination.

• 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 source and destination labels with the sending router interface label as a source and the next hop router label as a destination.

Which type of route does R1 use to reach host 10.10.13.10/32

• floating static

• host route

• default route

• network route

What is the metric of the route to the 192.168.10.33/28 subnet?

• 84

• 110

• 128

• 192

• 193

Which attribute does a router use to select the best path when two or more different routes to the same destination exist from two different routing protocols?

• DUAL algorithm

• metric

• administrative distance

• hop count

By default, how does EIGRP determine the metric of a router for the routing table?

• It uses the bandwidth and delay values of the path to calculate the route metric.

• It uses a default metric of 10 for all routes that are learned by the router.

• It uses a reference bandwidth and the actual bandwidth of the connected link to calculate the route metric.

• It counts the number of hops between the receiving and destination routers and uses that value as the metric.

Router R1 must send all traffic without a matching routing table entry to 192.168.1.1. Which configuration accomplishes this task?

• ip route default-route 192.168.1.1

• ip route 192.168.1.1 0.0.0.0 0.0.0.0

• ip route 0.0.0.0 0.0.0.0 192.168.1.1

• ip default-gateway 192.168.1.1
