Exam NGFW-Engineer Topic 1 Question 109 Discussion

Actual exam question for Palo Alto Networks's NGFW-Engineer exam
Question #: 109
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

A link group for HA link monitoring is built from data-plane interfaces that represent forwarding links, which includes Layer 3, Layer 2, and virtual wire interfaces, while TAP interfaces are excluded because they are receive-only and do not provide a meaningful link state for upstream connectivity monitoring.
