Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 112

An administrator configures a new destination list in Cisco Umbrella so that the organization can block specific domains for its devices. What should be done to ensure that all subdomains of domain.com are blocked?

Answer options

• A. Configure the domain.com address in the block list.
• B. Configure the *.domain.com address in the block list.
• C. Configure the *.com address in the block list.
• D. Configure the *domain.com address in the block list.

Correct answer: A

Explanation

The correct answer is A because simply adding domain.com to the block list will effectively block all its subdomains as well. Option B is incorrect since configuring *.domain.com is not necessary when domain.com itself is blocked. Options C and D do not specifically target all subdomains of domain.com, making them unsuitable choices.
