Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 90

A network administrator is configuring an application-aware firewall between inside zones to an outside zone on a WAN Edge router using vManage GUI. Which kind of inspection is performed when the `inspect` action is used?

Answer options

• A. Layer 7 inspection for TCP and Layer 4 inspection for UDP
• B. stateful inspection for TCP and stateless inspection of UDP
• C. IPS inspection for TCP and Layer 4 inspection for UDP
• D. stateful inspection for TCP and UDP

Correct answer: D

Explanation

The correct answer is D because the `inspect` action enables stateful inspection for both TCP and UDP protocols, allowing the firewall to track the state of active connections. The other options incorrectly describe the types of inspection performed, such as stateless inspection or limiting inspection to only one protocol type.
