Which capability provides outbound DNS query processing to improve network efficiency and security?

• A. Enterprise Recursive Services (ERS)
• B. Enterprise DNS Firewall
• C. Regional DNS Gateway
• D. Secure Recursive Network

Answer: (A)

Outbound DNS query processing is most effective when the enterprise acts as the primary resolver for internal clients, handling recursive lookups, caching results, and applying security policies at the boundary. Enterprise Recursive Services provides exactly that: it serves as the internal resolver, caches frequently accessed domain responses to speed up future lookups, and enforces policies to protect the network. This combination reduces unnecessary traffic to upstream DNS servers, lowers latency for users, and strengthens security by controlling how DNS queries are processed and which domains are allowed or blocked. The other options offer valuable security or regional benefits, but they don’t target the dual goal of efficient outbound processing plus broad, centralized security controls in the same way.
