Palo Alto Networks NGFW-Engineer Exam - Topic 2 Question 16 Discussion

Actual exam question for Palo Alto Networks's NGFW-Engineer exam

Question #: 16
Topic #: 2

Which configuration in the LACP tab will enable pre-negotiation for an Aggregate Ethernet (AE) interface on a Palo Alto Networks high availability (HA) active/passive pair?

ASet Transmission Rate to ''fast.''

BSet passive link state to ''Auto.''

CSet ''Enable in HA Passive State.''

DSet LACP mode to ''Active.''

Show Suggested Answer

Suggested Answer: C

In a High Availability (HA) active/passive pair configuration, when setting up an Aggregate Ethernet (AE) interface, enabling the 'Enable in HA Passive State' option allows the interface to participate in LACP (Link Aggregation Control Protocol) even when the system is in the passive state. This ensures that the pre-negotiation of the LACP link occurs, allowing the link aggregation to be ready as soon as the firewall becomes active.

A) Set Transmission Rate to "fast." is not the right answer. That's just about the LACP transmission rate, not HA pre-negotiation.

D) Set LACP mode to "Active." is a good option, but it doesn't specifically address the HA passive state requirement.

C) Set "Enable in HA Passive State." is the correct answer. This enables pre-negotiation for the AE interface on the HA passive device.

I thought "Auto" for passive link state was a good option, but now I'm questioning if it really impacts the pre-negotiation process.

I’m leaning towards A, but I’m not confident. I know transmission rates can affect performance, but I’m not sure if it’s the key for pre-negotiation.

I remember practicing a similar question, and I feel like setting the LACP mode to "Active" is important, but I can't recall if it directly relates to pre-negotiation.

I think the answer might be C, but I'm not entirely sure if "Enable in HA Passive State" is the right choice for pre-negotiation.

I feel pretty confident that C is the right answer here. Enabling LACP in the HA passive state seems like the way to get pre-negotiation working.

Setting the passive link state to "Auto" sounds like it could be related to pre-negotiation, but I'm not totally sure. I'll have to think it through.

I'm a bit confused on the difference between "fast" and "active" LACP modes. I'll need to review those details before deciding.

Okay, let's see. I think the key is to enable pre-negotiation for the HA active/passive pair. I'm guessing C might be the right answer.

Hmm, this seems like a tricky LACP configuration question. I'll need to think through the options carefully.
