Discuss Cisco 300-715 Exam Topic 1 Question 116

Which two probes must be enabled for the ARP cache to function in the Cisco ISE profile service so that a user can reliably bind the IP address and MAC addresses of endpoints? (Choose two.)

Suggested Answer: D, E

Cisco ISE implements an ARP cache in the profiling service, so that you can reliably map the IP addresses and the MAC addresses of endpoints. For the ARP cache to function, you must enable either the DHCP probe or the RADIUS probe. The DHCP and RADIUS probes carry the IP addresses and the MAC addresses of endpoints in the payload data. The dhcp-requested address attribute in the DHCP probe and the Framed-IP-address attribute in the RADIUS probe carry the IP addresses of endpoints, along with their MAC addresses, which can be mapped and stored in the ARP cache.

Same here, B and D are the best options for ARP cache functionality.

Huey 6 months ago

I feel confident about B and D. They’re essential for endpoint identification.

Ivan 6 months ago

No way, A and E don’t fit. B and D are the clear choices.

Tu 7 months ago

I’m leaning towards A and E. NetFlow and RADIUS could be relevant too.

Deane 7 months ago

I agree, B and D make sense. They help with IP and MAC binding.

Gail 7 months ago

I think it's B and D. SNMP and DHCP are crucial for ARP.

Felix 7 months ago

RADIUS makes sense, but I’m not convinced about DHCP.

Paris 7 months ago

Yup, DHCP is a must!

Lashaunda 8 months ago

Wait, are you sure about that?

Cherilyn 8 months ago

I thought SNMP was also required?

Leatha 8 months ago

Definitely need DHCP and RADIUS for ARP cache.

Lashawn 8 months ago

Wait, isn't the answer B and D? SNMP and DHCP? I'm pretty sure that's it.

Margot 9 months ago

B and E, no doubt. SNMP and RADIUS are the probes you need. This is a piece of cake!

Devora 9 months ago

Hmm, I think the answer is B and E. SNMP and RADIUS. Makes sense to me.

Kerry 9 months ago

I practiced a similar question, and I think it was definitely DHCP and maybe RADIUS, but I’m not confident about RADIUS.

Arlene 9 months ago

I feel like NetFlow could be involved, but I don't think it directly relates to ARP cache functionality.

Alyce 9 months ago

I remember something about needing DHCP for IP address binding, but I can't recall the second probe.

Stefan 9 months ago

I think it might be DHCP and SNMP, but I'm not entirely sure about SNMP.

Odette 10 months ago

Alright, I'm feeling more confident about this now. I'll carefully consider each of the options and eliminate the ones that don't seem directly related to the ARP cache.

Minna 10 months ago

I think I've got a strategy here. I'll need to review my notes on the different probes and their functions to determine which two are most relevant for the ARP cache.

Cheryl 10 months ago

I'm pretty sure the answer is B and D. SNMP and DHCP, right?

Phil 10 months ago

B and E are the correct answers. SNMP and RADIUS are required for the ARP cache to function in the Cisco ISE profile service.

Dick 11 months ago

I'm a bit confused on this one. I'm not sure which probes are specifically required for the ARP cache to function in the Cisco ISE profile service.

Tatum 11 months ago

B and E for sure. SNMP and RADIUS are the way to go. Easy peasy!

Filiberto 11 months ago

Okay, let's see. I know the ARP cache is used to map IP addresses to MAC addresses, so I'll need to figure out which probes are involved in that process.

Aron 11 months ago

Hmm, this seems like a tricky one. I'll need to think carefully about the different probes and how they relate to the ARP cache.

Lenita 5 months ago

↳ replying to Aron

I’m leaning towards those two as well!

Van 6 months ago

↳ replying to Aron

So, SNMP and DHCP? Sounds right.

Raymon 6 months ago

↳ replying to Aron

DHCP makes sense for binding IPs and MACs.

Derick 6 months ago

↳ replying to Aron

Yeah, I agree. But what about DHCP?

Johnetta 10 months ago

↳ replying to Aron

I think SNMP is definitely one of them.
