Cisco 300-615 Exam - Topic 2 Question 87 Discussion

Actual exam question for Cisco's 300-615 exam

Question #: 87
Topic #: 2

"A network engineer troubleshoots an issue at a Cisco data center environment with these conditions:

* The data center has Cisco Nexus 9000 Series Switches running the vPC setup.

* The gateway of the servers is an HSRP IP address between the VLAN interfaces configured on both Cisco Nexus switches.

* Some of the client application servers are implementing fast-path forwarding for the return traffic.

* Those servers are sending the return traffic to the VLAN interface MAC address instead of the HSRP MAC address.

The network engineer discovers that some traffic is dropped because it passes the vPC peer link to be forwarded out the vPC interface. What must be configured on the vPC switches to resolve the issue?

Apeer-switch

Bpeer-gateway

Carp synchronize

Dspanning-tree

I disagree, spanning-tree shouldn't be involved here at all.

Surprised this issue even came up with HSRP in play.

Peer-switch is a must for vPC setups, no doubt!

I thought arp synchronize was the way to go?

Definitely need to configure peer-gateway for this setup.

I’m pretty certain that "peer-gateway" is what we need to configure to handle the traffic correctly, but I wish I had reviewed that section more thoroughly.

I feel like "peer-switch" could be relevant, but I can't recall the exact implications of enabling it.

This situation sounds familiar; I think we had a practice question about traffic forwarding in vPC setups. I might lean towards "arp synchronize" since it deals with MAC address issues.

I remember studying about vPC configurations, but I'm not entirely sure if "peer-gateway" is the right choice here.

Okay, let me think this through. The traffic is being dropped because it's passing the vPC peer link, so we need to configure something to handle that. I'm leaning towards the arp synchronize option, but I'll double-check the other choices too.

Hmm, the key seems to be the fast-path forwarding on the servers sending traffic to the VLAN interface MAC instead of the HSRP MAC. I think the peer-gateway option might be the way to go here.

This looks like a tricky one. I'll need to carefully read through the details to understand the issue and the possible solutions.

This seems like a common vPC issue. I'm pretty sure the peer-gateway command is the right solution to make the vPC switches act as a single gateway for the HSRP group.

Hmm, this is a tricky one. The company wants to move to AWS without re-architecting the application, which limits our options. I'll need to think through the trade-offs of each solution to find the one that best meets all the requirements.

I'm a bit confused by the terminology here. What exactly is a "realm" in the context of Real Application Security? I'll need to review my notes to make sure I understand the concepts.

I'm not totally sure about this one. I'll have to review my notes on the theory of constraints to try to figure out the best answer.

I bet the network engineer wishes they had a 'magic wand' to fix this issue. But 'peer-gateway' is the way to go.

Okay, I see the servers are using the VLAN interface MAC instead of the HSRP MAC. 'Peer-gateway' should help with that.

I agree with Cassandra, because peer-gateway allows the vPC switch to act as the gateway for the servers.

I agree with Willie, because peer-gateway allows the vPC peer switches to act as the active gateway for packets that are addressed to the HSRP IP address.
