Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable 'Sinkhole' and specify the IP address for the sinkhole.
Why this is correct
Sinkholing is essential to identify infected clients.
- ✗
Configure 'DNS over HTTPS' to force all traffic through the firewall.
Why it's wrong here
DoH is a separate protocol and does not directly configure security profiles.
- ✓
Select the categories to block under the 'DNS Categories' tab.
Why this is correct
Selecting categories is required for the DNS Security engine to know what to block.
- ✗
Create a 'DNS Proxy' object for every zone.
Why it's wrong here
DNS Proxy is for DNS service management, not DNS security policy.
- ✗
Enable 'Packet Capture' for all DNS traffic.
Why it's wrong here
This is not required for DNS security protection.
