Huawei H12-821_V1.0 Exam - Topic 1 Question 42 Discussion

Which of the following statements regarding the stateful inspection firewall is true?
A) When the stateful inspection firewall checks packets, packets of one same connection are not correlated.
B) Because UDP is a connectionless protocol, so the stateful inspection firewall cannot match UDP packets with the status table.
C) The stateful inspection firewall only needs to match the first data packet against a rule, and the subsequent packets of the connection are matched directly in the state table.
D) The stateful inspection firewall needs to match the rules for each incoming packet.

A seems wrong, they do correlate packets in a connection.

I recall that stateful firewalls track connections, so option A seems incorrect. They definitely correlate packets from the same connection.

I practiced a similar question where the firewall's behavior was discussed, and I feel like option D is wrong since stateful firewalls usually don't check every packet against the rules.

I'm not entirely sure, but I remember something about UDP being tricky for stateful firewalls. Maybe option B is correct?

I think option C sounds familiar because it mentions matching the first data packet and then using the state table for the rest. That seems right.

I'm a bit unsure about this one. Is the WBS just for the overall project, or does it include the individual tasks as well? I'll need to review my notes to be sure.

Alright, I've got it. The issue is that PE1 can't see the VPNv4 routes because it only has an iBGP relationship with Router 1, which is a route reflector client. The solution is to configure Router 1 as a route reflector for PE1 under the VPNv4 address family. That should do the trick.

I'm a bit unsure about the difference between the http and ssl persistence options. I'll need to review those in more detail to make sure I select the right one for this scenario.

I recall something about insulation being problematic at lower temps too, but 25 F to 250 F feels off. I lean towards the higher range options.

Man, I'm glad I read through the options carefully. If I just saw 'stateful firewall' and picked the first answer, I would have been way off base. This stuff really requires understanding the core concepts.

Yeah, it's important to pay attention to the details. The stateful inspection firewall works differently than just matching rules for each incoming packet.

Option D sounds like it would be super inefficient. Matching every single packet against the full rule set? No way, that's not how a stateful firewall works at all.

Haha, option A is pretty funny. Of course the stateful firewall correlates packets of the same connection, that's the whole reason it's called 'stateful'!

I was a bit confused by option B. Just because UDP is connectionless, it doesn't mean the stateful firewall can't track and match UDP packets based on the connection state. That's kind of the whole point of stateful inspection!

Option C seems to be the correct answer. The stateful inspection firewall keeps track of the connection state, so it only needs to match the first packet against the rules, and then can quickly match subsequent packets in the state table.
