Nokia Exam 4A0-112 Topic 3 Question 8 Discussion

Actual exam question for Nokia's 4A0-112 exam

Question #: 8
Topic #: 3

Refer to the exhibit.

All routers in the diagram are running a link-state routing protocol. Before the link failure, all routers have operational adjacencies with each other and there is a BFD session between routers R1 and R3. After the link failure, which of the following affects the routing protocol's convergence time?

AThe value of the Ethernet hello timers on the switches.

BThe value of the routing protocol hello timers on routers R1 and R3.

CThe value of the BFD transmit interval, receive interval and multiplier settings on routers R1 and R3.

DThe time taken by the switches to detect that the physical ports are down.

Show Suggested Answer

Suggested Answer: B

The routing table manager (RTM) is responsible for selecting the best route when multiple routing protocols provide a route for the same destination prefix. It makes the decision on which route to add to the routing table based on the administrative distance, metric, and other criteria.

Seriously, guys? You're all overthinking this. The correct answer is obviously C, because Cisco loves their fancy acronyms like BFD. *chuckles* Next question: How many routers can dance on the head of a pin?

I think you might be right, C does seem like the most logical choice.

I'm gonna go with D, just to be different. Those switch detection times are always tricky, and the exam writers love to throw in a curveball like that. *winks* Gotta keep 'em on their toes, am I right?

I'm with Emogene on this one. The BFD settings are the key factor here. Who cares about those silly Ethernet hello timers or the switch detection time? This is a routing protocol question, after all.

Exactly, focusing on the BFD settings is essential for optimizing the routing protocol's convergence time.

Yeah, the BFD transmit interval, receive interval, and multiplier settings play a crucial role in detecting link failures quickly.

I agree, the BFD settings on routers R1 and R3 will definitely affect the routing protocol's convergence time.

Hmm, I'm not so sure. The BFD settings are important, but the time it takes the switches to detect the link failure could also play a big role. Gotta think this through carefully.

User 3: Both factors are important for routing protocol convergence. We need to consider them both.

User 2: I agree, but we shouldn't overlook the time it takes for the switches to detect the link failure.

C'mon, it's obviously C! Those BFD settings are crucial for fast convergence. I bet the exam writers are trying to trip us up with those other options.
