Sample Questions for Nokia 4A0-112 Exam Preparation

Question 1

Consider the exhibit.

4A0-112 Exam Question 1 Exhibit 1

All routers are running IS-IS with IPv6 support enabled. Based on the topology shown, and the route tables of routers R3 and R4, which of the following statements is TRUE?

AThere is no route leaking configured on router R1 or router R2.

BRoute leaking is configured on router R1 but not on router R2.

CRoute leaking is configured on router R2 but not on router R1.

DRoute leaking is configured on both routers R1 and R2.

Correct : D

Based on the IPv6 route table output for R3 and R4, we can see that the routers have remote routes listed as 'Remote ISIS', indicating that the route is being advertised from a different area (area 49.01 or 49.02). This is a sign of route leaking, where routes from one area are being shared across areas.

The routes from R3 (level-1 router) are being advertised to R4 (level-1 router), and vice versa, with ISIS as the protocol. This implies that there is route leaking configured to allow information to pass between areas.

Question 2

Consider the exhibit.

4A0-112 Exam Question 2 Exhibit 1

All routers are running IS-IS with IPv6 support enabled. Based on the topology shown, and the route tables of routers R3 and R4, which of the following statements is TRUE?

AThere is no route leaking configured on router R1 or router R2.

BRoute leaking is configured on router R1 but not on router R2.

CRoute leaking is configured on router R2 but not on router R1.

DRoute leaking is configured on both routers R1 and R2.

Correct : D

From the route tables of R3 and R4, we can see that remote routes are present, with R3 and R4 both having routes referencing routers in different areas (Area 49.01 and 49.02). These remote routes are characteristic of route leaking, which is the process of sharing routes between different IS-IS areas.

R3 has routes for R1, R2, and R4, which are in Area 49.01, suggesting that R1 and R2 have advertised their routes to R3, possibly due to route leaking.

R4 has similar routes for R2 and R3, indicating that R2 might have advertised its routes to R4.

This sharing of routes between areas is indicative of route leaking being configured on both R1 and R2, allowing these routes to be shared across the areas.
