Exam NGFW-Engineer Topic 1 Question 67 Discussion

Actual exam question for Palo Alto Networks's NGFW-Engineer exam
Question #: 67
Topic #: 1
A Palo Alto Networks firewall has the following interfaces configured:
* ethernet1/1 (Layer 3)
* ethernet1/2 (TAP)
* ethernet1/3 (Layer 2)
* ethernet1/4 (virtual wire)
An administrator needs to create a link group to monitor upstream connectivity for high availability (HA) failover.
Which set of interfaces can be added to the link group?

Suggested Answer: D Vote an answer

Basic Concept: HA link monitoring uses production forwarding interfaces. HA links themselves are not monitored as production links, and TAP is not a forwarding path.
Why D is Correct: Layer 3, Layer 2, and virtual wire interfaces can be included in link groups because they carry live traffic.
Why A is Wrong: ethernet1/1, ethernet1/2, ethernet1/4 is an HA-related setting or behavior, but it is not the specific HA link, LACP pre-negotiation option, or upgrade sequence required here.
Why B is Wrong: ethernet1/1, ethernet1/2, ethernet1/3 is an HA-related setting or behavior, but it is not the specific HA link, LACP pre-negotiation option, or upgrade sequence required here.
Why C is Wrong: ethernet1/2, ethernet1/3, ethernet1/4 is an HA-related setting or behavior, but it is not the specific HA link, LACP pre-negotiation option, or upgrade sequence required here.
