Huawei Exam H12-721 Topic 4 Question 91 Discussion

Actual exam question for Huawei's H12-721 exam

Question #: 91
Topic #: 4

Static fingerprint filtering function, different processing methods for different messages, the following statement is correct?

ATCP/UDP/custom service can extract fingerprints based on the payload (ie the data segment of the message)

BDNS packet extracts fingerprints for Query ID

CHTTP message extracts fingerprint for universal resource identifier URI

DICMP message extracts fingerprint by identifier

Show Suggested Answer

Suggested Answer: A, C

Note: By configuring a static fingerprint, the packets that hit the fingerprint are processed accordingly to defend against attack traffic. First, the TCP/UDP/custom service can extract fingerprints based on the payload (that is, the data segment of the packet); second, the DNS packet extracts the fingerprint for the domain name; and third, the HTTP packet is extracted for the Uniform Resource Identifier (URI). fingerprint.

I'm not sure about option B) DNS packet extracts fingerprints for Query ID, it seems a bit off to me.

I believe option C) HTTP message extracts fingerprint for universal resource identifier URI is also correct, as URI is a key component of HTTP messages.

My money's on A. TCP/UDP/custom service payloads are the bread and butter of fingerprint extraction. Gotta love those juicy data segments!

C seems like a good choice too, extracting fingerprints from HTTP messages based on URI.

I think B is also a valid option for extracting fingerprints from DNS packets.

Haha, I bet the answer is B. Extracting fingerprints from DNS Query IDs? That's a classic network security trick, like finding Waldo in a haystack!

I agree with Ora, because the payload contains the actual data being transmitted.

D seems like the right answer to me. ICMP messages have an identifier field that can be used to extract a fingerprint. The question is about different processing methods for different message types, and that fits the description.

I think the correct answer is C. HTTP message extracts fingerprint for universal resource identifier URI. The question is specifically asking about static fingerprint filtering, and HTTP headers like the URI are commonly used for that purpose.
