A. B. C. D.A.
https://blog.finjan.com/email-spoofing/To prevent outside entities from spoofing the company's email domain, the security technician needs to implement an SPF (Sender Policy Framework) record. SPF is an email authentication protocol that allows domain owners to specify which mail servers are authorized to send email on behalf of their domain.
To accomplish this task, the security technician should add an SPF record to the DNS (Domain Name System) record of the domain. The SPF record is a TXT (text) record that specifies the authorized mail servers for the domain. The SPF record should be added to the top-level domain (i.e., the @ record).
Option A is the correct answer, as it specifies the correct TXT record that should be added to the DNS record. The SPF record for the domain should be "v=spf1 mx include:_spf.comptia.org -all".
Option B is incorrect because the SPF record should be added to the DNS record, not the email server.
Option C is incorrect because the SPF record should be added to the DNS record, not the domain controller.
Option D is incorrect because the SPF record should be added to the DNS record, not the web server.
In summary, the correct action that the security technician should take to prevent outside entities from spoofing the company's email domain is to add the SPF record "v=spf1 mx include:_spf.comptia.org -all" to the DNS record of the domain.
