350-701 Practice Question: A company uses Cisco Umbrella for DNS-layer…
A company uses Cisco Umbrella for DNS-layer security. They want to block access to known malicious IPs that may be resolved by non-DNS traffic. Which feature should they enable?
⚠ Common exam trap
Cisco often tests the distinction between DNS-layer security (which only blocks based on domain names) and IP-layer enforcement (which blocks based on IP addresses), leading candidates to mistakenly choose HTTPS Inspection or File Analysis as they associate them with security inspection rather than IP-based blocking.
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
✓
IP Layer Enforcement
IP Layer Enforcement is the correct feature because it allows Cisco Umbrella to block traffic to known malicious IP addresses even when the traffic does not originate from a DNS query. This is essential for blocking threats that use hardcoded IPs or non-DNS protocols like direct IP connections, ensuring protection beyond DNS-layer filtering.
