Explanation
DNS-Layer security (Cisco Umbrella) protects against threats that traverse internet-based communication channels by blocking malicious DNS requests before a connection is made. Web browsing (C), email (D), and cloud application access (E) all rely on DNS resolution, making them vectors where DNS-layer enforcement is effective-blocking access to malicious domains used in phishing, malware delivery, and command-and-control callbacks. Voicemail (A), backups (B), and video surveillance (F) are internal or infrastructure-oriented channels that do not route through DNS in a way that Umbrella is designed to intercept and protect.
