Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 396

Which feature blocks malware, phishing, and unacceptable requests to provide faster internet access to users in SD-WAN security solutions?

Answer options

• A. SaaS usage controls
• B. DNS-layer enforcement
• C. cloud-delivered firewall
• D. correlated threat intel

Correct answer: B

Explanation

DNS-layer enforcement effectively blocks harmful content and phishing attempts by filtering requests at the DNS level, which improves internet speed for users. The other options, while important for security, do not specifically focus on blocking these types of threats at the DNS level, thus they do not directly enhance user internet access in the same manner.
