Exam 220-1101 topic 1 question 68 discussion

DMARC is used to prevent an organizations "outgoing" email from being marked as spam. The question explains that the spam is incoming and DMARC would do nothing to help the organization from receiving spam from different domains. Keywords are mostly the same with these incoming spam messages. Update your keywords and be done with it. Those of you who believe DMARC is the answer, please spend 20 or more minutes researching it and how it works. It is used to prevent spoofing and phishing of your own organizations email.

Looks like it's D. According to demarc.org: DMARC is designed to fit into an organization’s existing inbound email authentication process. The way it works is to help email receivers determine if the purported message “aligns” with what the receiver knows about the sender...Reduce successful phishing delivery. In other words, it validates authenticity of incoming emails. Looks like the company is receiving phishing emails from multiple fake senders.

❌⚠️ Possible Half-right confusion explained: DMARC (Option D) could seem tempting because it's generally good security practice. However, DMARC’s effectiveness is limited to controlling spoofed messages pretending to be from trusted or authoritative domains. It doesn't effectively mitigate spam from random external domains. ✅ Why Option A (Updating keyword filtering) is Correct: The scenario specifically mentions: Spam emails from various sending domains (implying that filtering based on domains alone isn't effective). The emails contain the same general content (keywords and text patterns). Updating keyword filtering is the quickest and most efficient way to mitigate this specific type of spam issue, as you target the email content rather than the constantly changing sender domains.

according to the compTIA A+ D is the right answer? chatGPT prompt: what is the correct answer to this question according to the CompTIA +A material? "Recently, an organization received a number of spam emails that passed through the spam gateway. These emails contained generally the same information, but the sending domains were different. Which of the following solutions would BEST help mitigate the issue?" ChatGPT answer: The best solution to mitigate this issue, according to CompTIA A+ material, would be to implement a Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), or Domain-based Message Authentication, Reporting & Conformance (DMARC) policy. These email authentication methods help verify that emails come from legitimate sources, reducing the chance of spam and phishing emails bypassing security measures.

DMARC combines SPF and DKIM which is why it’s the BEST choice is D.

DDMARC (Domain-based Message Authentication, Reporting, and Conformance) works with SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to authenticate email senders and prevent spoofing. Enabling and properly configuring DMARC ensures that only legitimate emails from authorized senders pass through the spam gateway. This would help mitigate the issue of spam emails with different sending domains because spoofed domains would be flagged.

what wehn the email adress is legit but the content of the email is still spam ? so I Think A must be True

The best solution to mitigate the issue of spam emails from different sending domains would be D. Verifying DMARC is enabled. DMARC (Domain-based Message Authentication, Reporting & Conformance) helps to authenticate emails by ensuring that they come from legitimate sources, thus reducing the likelihood of spam emails passing through the gateway

In this scenario, where the organization is receiving spam emails that passed through the spam gateway, the best option to mitigate the issue would be: A. Updating the keyword filtering Explanation: Updating the keyword filtering: This action can help improve the detection of spam emails by adding or refining keywords that are commonly found in spam messages. Since the emails have similar content but come from different domains, enhancing keyword filtering can increase the chances of catching these unwanted emails. Why the other options are less suitable: B. Editing the sender policy framework: SPF is more relevant for the sender's domain and wouldn't directly help the recipient with incoming spam from various domains. C. Contacting the gateway vendor: While this could be useful for troubleshooting, it does not provide an immediate solution to the spam issue. D. Verifying DMARC is enabled: This is more relevant for the outgoing emails from the organization and doesn't directly address the incoming spam.

Updating the keyword filtering ,the organizations can modify the filtering rules to include keyword and phrases that are common in spam emails they recieved. By creating and updating filtering rules can help the orginazations to pinpoint the spam emails coming from the different domians.

"Sending domains were different" maybe the senders are spoofing where they are actually sending from. From the internet. \/ "Domain-based Message Authentication Reporting & Conformance (DMARC) is an email security protocol. DMARC verifies email senders by building on the Domain Name System (DNS), DomainKeys Identified Mail (DKIM), and Sender Policy Framework (SPF) protocols."

D. Verifying DMARC is enabled. DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that helps prevent email spoofing and phishing. By enabling DMARC, organizations can specify how their emails should be authenticated and what actions should be taken for emails that fail authentication. This can include marking them as spam or rejecting them outright. Enabling DMARC can help ensure that only legitimate emails from authorized sending domains are accepted, reducing the chances of spam emails with different sending domains passing through the gateway. While options A (Updating the keyword filtering), B (Editing the sender policy framework), and C (Contacting the gateway vendor) can be relevant in certain situations, DMARC is specifically designed to address email authentication and can be effective in preventing email spoofing and phishing attacks.

I think D is correct.

"DMARC, DKIM, and SPF are three email authentication methods. Together, they help prevent spammers, phishers, and other unauthorized parties from SENDING emails on behalf of a domain* they do not own." DMARC is a protocol for outbound mail, not inbound. Therefore, A is the most appropriate answer. https://www.cloudflare.com/learning/email-security/dmarc-dkim-spf/

Can someone explain why is not B: SPF. SPF is a standard email authentication method. SPF helps protect your domain against spoofing, and helps prevent your outgoing messages from being marked as spam by receiving servers. SPF specifies the mail servers that are allowed to send email for your domain.

DMARC helps protect email senders and recipients from advanced threats that can be the source of an email data breach.

Selected: Answer: D. Domain-based Message Authentication Reporting and Conformance (DMARC): An email validation system that detects and prevents email spoofing. It helps combat certain techniques often used in phishing and email spam, such as emails with forged sender addresses that appear to come from legitimate organisations.
