Which option allows or denies program communication on devices?

• A. Program Rules
• B. Email Antivirus
• C. Web Browsing Antivirus
• D. Heuristics

Answer: (A)

The concept being tested is controlling whether programs can communicate over the network by using a policy that explicitly allows or denies their communications. Program Rules provide a direct mechanism to specify, for each application, what network destinations, ports, and protocols are permitted or blocked. This lets administrators prevent unauthorized data exfiltration or malicious apps from reaching external servers, while still allowing legitimate functionality for trusted programs.

Email Antivirus and Web Browsing Antivirus focus on protecting through content scanning and threat blocking in specific channels (email and web traffic), not on granting or denying a program’s network communications in a general policy. Heuristics is a detection approach that identifies suspicious behavior or unknown threats, rather than a configurable policy to permit or restrict a program’s communications.
