Discuss Dell D-SNC-DY-00 Exam Topic 1 Question 1

Refer to the exhibit.

The router ID has not been manually configured. What router ID is used for Switch 3?

A192.168.100.2

B192.168.100.0

C10.0.2.1

D10.0.1.1

Suggested Answer: D

In the absence of a manually configured router ID, OSPF typically uses the highest IP address on the switch's active interfaces. For Switch 3 in the exhibit, the highest IP address is 10.0.1.1 on Loopback 0. Therefore, 10.0.1.1 is used as the router ID for Switch 3.

I disagree, it should be 10.0.2.1 based on the subnet.

Scarlet 11 months ago

Wait, is it really 192.168.100.2? That seems off!

Scarlet 11 months ago

I thought it would be 10.0.1.1, but I guess not.

Pamella 11 months ago

Definitely going with 192.168.100.2!

Jacquline 11 months ago

The default router ID is usually the highest IP address.

Sean 12 months ago

I’m confused about the default behavior. Does it always pick the highest IP, or could it be something else like the loopback address?

Kenneth 12 months ago

I feel like I’ve seen something similar, but I can’t recall if it was about the highest IP or something else. Could it be 10.0.2.1 instead?

Chandra 12 months ago

I remember a practice question where we had to determine the router ID based on the highest IP address, so I might lean towards 192.168.100.2 if that's the highest.

Hassie 1 year ago

I think the router ID defaults to the highest IP address on the active interfaces, but I'm not completely sure if that's the case here.

Lavera 1 year ago

I'm a bit confused by this question. The exhibit doesn't seem to provide enough information for me to determine the router ID. I'll need to review my notes and try to apply the relevant concepts.

Sena 1 year ago

I think I know the answer, but I want to double-check my understanding before selecting an option. This is an important concept, so I want to make sure I get it right.

Britt 1 year ago

Okay, let's see. The question says the router ID has not been manually configured, so I need to figure out how the router ID is determined in that case.

Kenda 1 year ago

Hmm, this looks like a tricky one. I'll need to carefully analyze the information provided in the exhibit to determine the router ID used for Switch 3.

Verona 1 year ago

Ugh, I'm really struggling with this one. I'm not sure if it's about reading personality types, facial gestures, listening, or technical comprehension. I'll have to guess and hope for the best.

Junita 1 year ago

I'm pretty sure SSL uses asymmetric encryption, so I'll select that one. Symmetric encryption is also a possibility, but I'm less confident about that.

I agree with Latanya, 10.0.1.1 seems like the correct router ID for Switch 3

Benton 2 years ago

You know, I'm not even going to bother guessing on this one. I'm just going to go with my gut and pick A. It's probably wrong, but at least I'll have a chance at partial credit, right?

Ethan 2 years ago

Hmm, that makes sense. But I still think it's 192.168.100.2

Latanya 2 years ago

I believe it's 10.0.1.1 because of the network configuration

Misty 2 years ago

Haha, this is a trick question! The answer is clearly D, 10.0.1.1. I bet the exam writer is trying to confuse us with those other options.

Frederica 2 years ago

Hmm, I think it might be B, 192.168.100.0. That seems like a reasonable default if the router ID isn't set, right? I'm not too sure about this one, though.

Oh, really? I thought it was B, 192.168.100.0. Now I'm not sure.

Fernanda 2 years ago

↳ replying to Frederica

I think it's actually A, 192.168.100.2. That's the default router ID for Switch 3.

Ethan 2 years ago

I think the router ID for Switch 3 is 192.168.100.2

Merilyn 2 years ago

C'mon, everyone knows that the router ID is automatically assigned if not configured manually. The answer must be C, 10.0.2.1. Duh!

Gearldine 2 years ago

↳ replying to Merilyn

Thanks for the clarification. I understand now that the router ID for Switch 3 is 10.0.2.1. It makes sense.

Hayley 2 years ago

Yeah, that's right. The router ID for Switch 3 is indeed automatically assigned, which is 10.0.2.1.

Stanton 2 years ago

↳ replying to Merilyn

I agree, the router ID is automatically assigned if not configured manually. So the answer is C) 10.0.2.1.
