Cisco Practice Final Study Set 3

An administrator is troubleshooting an adjacency issue between two OSPFv3 routers. Which two neighbor states indicate a stable adjacency between the routers? (Choose two.)

-2way -full

Refer to the exhibit. What are three results for the DR and BDR elections for the given topologies? (Choose three.)

-R1 is DR for segment A. -R3 is BDR for segment A. -R5 is BDR for segment B.

Which wildcard mask would be used to advertise the 192.168.5.96/27 network as part of an OSPF configuration?

0.0.0.31

Fill in the blank. In RSTP, BPDU frames are sent every ________ seconds by default.

2

Fill in the blank. By default, EIGRP is able to use up to _____________percent of the bandwidth for EIGRP messages on an EIGRP-enabled interface.

50

On what type of OSPF router is interarea route summarization configured?

ABRs

Refer to the exhibit. A network administrator has configured OSPFv2 on the two Cisco routers as shown. The routers are unable to form a neighbor adjacency. What should be done to fix the problem?

Change the IP address on S0/0 of router R2 to 192.168.20.2.

Refer to the exhibit. Which address will R1 use as the source address for all OSPFv3 messages that will be sent to neighbors?

FE80::1

Refer to the exhibit. Suppose that routers B, C, and D have a default priority, and router A has a priority 0. Which conclusion can be drawn from the DR/BDR election process?​

If the DR fails, the new DR will be router B.

Fill in the blank. What is the acronym of an IGP, link-state, classless routing protocol besides IS-IS?

OSPF

Refer to the exhibit. On which router or routers would a default route be statically configured in a corporate environment that uses single area OSPF as the routing protocol?

R0-A

Refer to the exhibit. What can be concluded about network 192.168.1.0 in the R2 routing table?

This network was learned through summary LSAs from an ABR.

Which OSPFv3 function works differently from OSPFv2?

authentication

What address type will OSPFv3 use to form adjacencies to neighboring routers?

the link-local address of the interface

What is one reason to use the ip ospf priority command when the OSPF routing protocol is in use?

to influence the DR/BDR election process

What is the reason for a network engineer to alter the default reference bandwidth parameter when configuring OSPF?

to more accurately reflect the cost of links greater than 100 Mb/s

Fill in the blank. EIGRP keeps feasible successor routes in the ________________table.

topology

Which OSPF LSA type is only used in multiaccess and NBMA networks?

type 2

Which type of OSPF LSA represents an external route and is propagated across the entire OSPF domain?

type 5
