350-701 Practice Question: Which TWO of the following are correct about…
Which TWO of the following are correct about Cisco Umbrella's multi-layered security approach? (Choose two.)
⚠ Common exam trap
Cisco often tests the distinction between the core layers of Umbrella's multi-layered security (DNS-layer and proxy-based web inspection) and additional integrated features like sandboxing or IP reputation, which are not considered separate layers in the official architecture.

Correct answer & explanation
✓
DNS-layer security
DNS-layer security is a core component of Cisco Umbrella's multi-layered approach. It blocks requests to malicious domains at the earliest stage of the connection, before any IP address resolution occurs, by inspecting DNS queries against threat intelligence feeds. This prevents users from reaching known phishing, malware, or command-and-control (C2) domains.

Firewall as a Service

DNS-layer security
Why this is correct
First layer of defense by blocking requests to malicious domains.

IP reputation filtering
Why it's wrong here
IP reputation is part of DNS-layer, not a separate layer.
