Several employees submit the same phishing email to the administrator. The administrator finds that the links in
the email are not being blocked by the company’s security device. Which of the following might the
administrator do in the short term to prevent the emails from being received?

A.
Configure an ACL

B.
Implement a URL filter

C.
Add the domain to a block list

D.
Enable TLS on the mail server

Explanation:
Blocking e-mail is the same as preventing the receipt of those e-mails and this is done by applying a filter. But
the filter must be configured to block it. Thus, you should add that specific domain from where the e-mails are
being sent to the list of addresses that is to be blocked.
