Selected Answer: D
The answer is properly for this expiration that I have found in sybex Spam Management Email spam is a problem. The only people who don’t agree with this are the spammers themselves. One of the tricks that spammers use is to spoof (or fake) the domain name they are sending emails from. DNS, through the use of TXT records, can help email servers determine if incoming messages are from a trusted source rather than a spoofed one. Three standards used to battle email spam are Sender Policy Framework (SPF), Domain Keys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC). Each one can be used in a DNS TXT record to help thwart malicious users from using a company’s domain name to send unauthorized emails.

it says 'REMOVE and prevent any further emails'. Only B removes emails. The rest of them except A only filter them based on domain.

Hmmm...I don't see "domain-based filter" as part of the Comptia objectives..for sure "spam filter" is there but not domain-based filter. Per Prowse the 4 methods to prevent/troubleshoot spam are: Use a strong password: E-mail accounts can be hijacked if they have weak passwords Use a spam filter: This can be purchased for the server side as software or as an appliance. Train your users: Instruct users to create and use free e-mail addresses whenever they post to forums and newsgroups; and finally, Use whitelists and blacklists: Whitelists are lists of e-mail addresses or entire e-mail domains that are trusted, whereas blacklists are those that are not trusted. These lists can be set up on e-mail servers, e-mail appli- ances, and within mail client programs such as Outlook. I'll have to go with C based on that, since a whitelist is the only thing matching the objectives given by Comptia. In the real world yeah A or B probably work.

Found this question on Dion's exams as well Q: "An employee's inbox is now filled with unwanted emails after their email password had been compromised last week. You helped them reset their password and regain access to their account. Many of the emails are coming from different email addresses such as @yahoo.com, @gmail.com, and @hotmail.com. Which of the following actions should the user take to help reduce the amount of spam they receive? A: Mark each as spam/junk

Explanation OBJ-3.2: At the user level, the software can redirect spam to a junk folder or similar. Email filtering is any technique used to prevent a user from being overwhelmed with spam or junk email. Spam can be blocked from reaching an organization using a mail gateway to filter messages. Anti-spam filtering needs to balance blocking illegitimate traffic with permitting legitimate messages. Anti-spam techniques can also use lists of known spam servers by establishing a blocklist. If an allow list is used, only a small number of senders could send emails to the user. The technician should not create a domain-based email filter since the spammers are using Yahoo, Gmail, and Hotmail accounts to send the spam. If a domain-based email filter is created, it will block emails from all users on those email providers and prevent legitimate emails from being received.

It's not the same question. IF the emails were coming from Gmail, Yahoo, ect, then you would not use domain filtering. The question states the emails were thank you emails, thanking the user for joining a mailing list. So what comes next is a flood of newsletters, promotions, ect likely from different email addresses at the organization. The user will see none of this is the org domain is blocked.

Whitelist is quite harsh as won't allow any email from unrecognised email address. That means that many necessary emails may be missed. Normally is good use of it in emails for internal use.

No, in this case we don't want to start clicking on anonymous links just because they advertise "Unsubscribe". Deploy a domain based filter to begin blocking the emails and then delete the emails from the inbox.
