ISC2 SSCP Exam - Topic 4 Question 59 Discussion

Actual exam question for ISC2's SSCP exam
Question #: 59
Topic #: 4
[All SSCP Questions]

When a station communicates on the network for the first time, which of the following protocol would search for and find the Internet Protocol (IP) address that matches with a known Ethernet address?

Show Suggested Answer Hide Answer
Suggested Answer: B

The RARP protocol sends out a packet, which includes its MAC address and a request to be informed of the IP address that should be assigned to that MAC address.

ARP does the opposite by broadcasting a request to find the Ethernet address that matches a known IP address.

ICMP supports packets containing error, control, and informational messages (e.g. PING).

UDP runs over IP and is used primarily for broadcasting messages over a network.

Really? I didn't know ARP was so important for IP addressing!

I always mix up ARP and RARP, but I agree, ARP is right.

Wait, isn't ICMP used for error messages?

I thought it was RARP at first, but ARP makes more sense.

It's definitely A, ARP is the one that does that!

UDP doesn't seem right either; it's more about data transmission. I feel like ARP is the best choice here.

ICMP seems like it could be related, but I don't think it does address resolution. It's more about error messages, isn't it?

I remember practicing a question like this, and I think RARP is used for the opposite, finding a MAC from an IP.

I think it's ARP because it resolves IP addresses to MAC addresses, right? But I'm not completely sure.

This seems like a straightforward question about the document that outlines the seller's decision-making process for a project bid. I'm pretty confident the answer is B, Opportunity assessment.

This seems like a straightforward question about ensuring advance payments for specific contract types. I think option A is the best approach - creating a dedicated agreement type and using the advance receipts required extension.

I'm actually torn between "vlan" and "ucs_vlans." I feel like it might depend on the context of the playbook we're using.
