- A
It performs deep packet inspection on all traffic
Why wrong: DNS-layer security only inspects DNS queries, not full packet content.
- B
It blocks malicious domains before a connection is made
DNS-layer security stops connections to malicious domains at the initial DNS request.
- C
It provides SSL decryption for all web traffic
Why wrong: SSL decryption is a feature of the Secure Internet Gateway, not DNS-layer.
- D
It encrypts all DNS traffic to prevent eavesdropping
Why wrong: DNS-layer security does not inherently encrypt traffic; it blocks based on domain reputation.

Real-world example
How this comes up in practice
A practitioner preparing for the 350-701 exam encounters this exact type of scenario on the job.
