Link-state PDUs include an age field. Which of the following is FALSE?

Link-state PDUs include an age field. Which of the following is FALSE?

When link-state information reaches the maximum age on a router, the router will flood that information
to its neighbors.

The age value is updated as the information is flooded throughout the network and when it is in the
LSDB.

When a router detects that any of its link-state information has reached the maximum age, it will request
a new update from the source router.

Aging helps ensure that links, which are no longer part of the topology, will eventually get removed from
the LSDB.

It can reduce the topological database size.

It can reduce the number of Router LSAs.

It can reduce the size of the route table.

A static route has been configured on router R1 to reach the PC at 139.120.121.2. What else is required to
make the ping succeed?

A default route on router R2 to router R1.

A default route on router R1 to router R2.

A default route on the PC to router R2.

A static route on the PC to router R2 and a static route on router R2 to the PC.

Click on the exhibit.

All ports in the network are operationally up and have a speed of 1Gbps. Which of the following is TRUE?

Data traffic from network 192.168.1.0/24 to 192.168.3.0/24 will be forwarded through router R2.

The OSPF adjacency between router R1 and router R3 is operationally up.

Data traffic from network 192.168 3.0/24 to 192.168.1.0/24 will be forwarded from router R3 directly to
router R1.

The system interface of routers R1 and R3 must be included into OSPF for traffic to flow between the
192.168.1.0/24 and 192.168.3.0/24 networks.

Which of the following regarding the IS-IS PSNP is FALSE?

Which of the following regarding the IS-IS PSNP is FALSE?

PSNPs are used on point-to-point links to acknowledge the receipt of an LSP.

PSNPs are used by an IS-IS router to request LSP information from a neighboring router.

There are three types of PSNPs: Level 1, Level 2, and Level 1/2.

A PSNP lists some of the LSPs in the router's database.
Which of the following is NOT a field in the IPv6 header?

Which of the following is NOT a field in the IPv6 header?

Click on the exhibit.

In the topology shown, router R1 is an ASBR configured to export external routes to OSPF.
Assuming that there are no stub or NSSA networks, which of the following regarding LSAs is TRUE?

Only router R1 will generate Type 4 LSAs.

Routers R1.R3 and R6 will generate Type 4 LSAs.

Only router R3 will generate Type 4 LSAs.

Routers R3 and R6 will generate Type 4 LSAs.
Which of the following about IS-IS is FALSE?

Which of the following about IS-IS is FALSE?

IS-IS uses the concept of Level 1 and Level 2 routers to implement hierarchy.

A Level 1 router forwards traffic to other areas through the nearest Level 1/2 router.

An IS-IS router belongs to one or more areas.

All Level 2 routers belong to the same area.

Examine the physical topology of the IS-IS network, the metrics of the links and the levels of the routers. All
routers have a system address included in IS-IS.
Which of the following describes the route that router R4 will use to reach the system address of router R6?

Router R4 will have a route to router R6's system address with router R2 as the next-hop.

Router R4 will not have a route to router R6's system address, nor will it have a default route.

Router R4 will have a default route with router R2 as the next-hop.

Router R4 will have a default route with router R3 as the next-hop.

Click on the exhibit.

If router R2 re-distributes the IS-IS route 192.168.3.0/24 into OSPF, router R3 will receive two routes to
192.168.3.0/24 Assume that all IS-IS routers are L1/L2 capable and are in the same area.
What will be the preference of the two routes?

OSPF internal preference and IS-IS Level 1 internal preference.

OSPF external preference and IS-IS Level 1 external preference.

OSPF external preference and IS-IS Level 2 internal preference.

OSPF internal preference and IS-IS Level 1 external preference.
