What is a function of an end device configured with DHCPv6 guard?

Show Suggested Answer Hide Answer
Suggested Answer: C

The DHCPv6 Guard feature blocks reply and advertisement messages that come from unauthorized

DHCP servers and relay agents.

Packets are classified into one of the three DHCP type messages. All client messages are always

switched regardless of device role. DHCP server messages are only processed further if the device role

is set to server. Further processing of server messages includes DHCP server advertisements (for

source validation and server preference) and DHCP server replies (for permitted prefixes).

If the device is configured as a DHCP server, all the messages need to be switched, regardless of the

device role configuration.

Just to clarify, DHCPv6 guard is all about security, right?

Wait, are we sure about that? I thought clients could do more than just requests.

I think it's option D, only DHCP requests are allowed for clients.

I believe option D sounds correct since clients should only be sending DHCP requests, but I might be mixing it up with something else we covered.

I feel like I saw something similar in our study materials, but I can't recall if the guard allows any messages or just specific ones.

I remember practicing a question about DHCP roles, and I think if it's a client, it should only send requests, right?

I think DHCPv6 guard is meant to protect the network from rogue DHCP servers, but I'm not sure which option fits that best.

Okay, let me walk through this step-by-step. The question is asking about a document that details the bond sale process and timeline. The bond certificate is just the physical bond itself, so that's not it. The bond indenture is the legal contract, which is close but not exactly what they're asking for. That leaves the bond sale calendar as the best option. I'm feeling pretty confident about A as the answer.

Safety procedures make sense too, but I guess it depends on the context of the training session.

Alright, let me give it a try. I think I've got the right approach, but I'll double-check my work to make sure I don't miss anything.

I'm a bit confused about the best choice here. I can recall some key points from our study session, but none of the options seem to fit perfectly.
