NetSec-Architect Practice Question: NGFW And Cloud Delivered Security Services Architecture
A security architect is configuring an Anti-Spyware profile on a Palo Alto Networks NGFW. The team wants to ensure that hosts infected with malware attempt-to-communicate with known Command-and-Control (C2) servers are automatically isolated. Which feature in the Anti-Spyware profile should be configured to achieve this redirection?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DNS Sinkhole
DNS Sinkholing allows the firewall to intercept DNS requests to malicious domains and redirect the infected client to a sinkhole IP address, identifying compromised internal hosts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
WildFire file forwarding
Why it's wrong here
WildFire forwards suspicious files for sandbox analysis, not for redirecting DNS-based C2 traffic.
- ✓
DNS Sinkhole
Why this is correct
DNS Sinkhole intercepts malicious DNS lookups and redirects the traffic to a designated sinkhole IP address for host identification.
- ✗
Packet Capture (Pcap)
Why it's wrong here
Packet capture records network traffic for forensic analysis, but does not actively isolate or redirect infected hosts.
- ✗
URL filtering category override
Why it's wrong here
URL filtering category overrides change how specific websites are categorized, not DNS traffic or C2 redirection.
