350-701 Practice Question: Which THREE features are available in Cisco…
Which THREE features are available in Cisco Umbrella to protect against DNS-based threats? (Choose three.)
⚠ Common exam trap
Cisco often tests the distinction between DNS-layer security (which blocks at the query level) and IP-layer enforcement (which blocks at the network layer), and candidates mistakenly think DLP or anti-virus are part of Umbrella because they confuse it with other Cisco security products like WSA or Secure Endpoint.

Correct answer & explanation
✓
IP-layer enforcement
Cisco Umbrella provides DNS-layer security (option C) as its core function, intercepting DNS queries to block requests to malicious domains before a connection is established. IP-layer enforcement (option A) extends protection by applying policies based on the destination IP address, blocking traffic to known malicious IPs even if DNS resolution is bypassed. Application control (option B) allows administrators to permit or block specific cloud applications (e.g., Dropbox, Facebook) at the DNS level, preventing data exfiltration or unauthorized usage through DNS-based application identification.
