DMARC
SPF
DKIM
Try practice test
You work as a network administrator for a company, "example.com", that recently started experiencing issues with email spoofing. To mitigate the problem, you decide to implement DMARC (Domain-based Message Authentication, Reporting & Conformance) in addition to existing SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records.

Your current DNS records for example.com include the following:

- MX 10 mail.example.com (IP address 203.0.113.10)
- TXT "v=spf1 ip4:203.0.113.10 -all"
- TXT "v=DKIM1; k=rsa; p=public-key-here"

You add the following DMARC record:

- TXT "_dmarc.example.com" "v=DMARC1; p=quarantine; pct=100; rua=mailto:[email protected]"

After implementing the DMARC record, an external mail server sends an email to your domain. The email passes the SPF and DKIM checks but fails the DMARC check.

What will likely happen to the email?
A: The email will be accepted and delivered to the recipient's inbox.
B: The email will be rejected and returned to the sender as undeliverable.
C: The email might be delivered to the recipient's spam or junk folder.
D: The email will be accepted, but a report will be sent to the sender.
E: The email will be silently discarded, and the sender will not be notified.

You are a network administrator for an e-commerce company. The company's online store allows customers to browse products and make purchases securely over the internet. The online store uses SSL/TLS for secure communication. You receive reports that some customers are seeing a security warning in their web browsers when trying to access the online store. Upon investigation, you discover the following information:

- The SSL certificate used by the online store's web server is valid for one year and is due to expire in two days.
- The web server is configured to automatically redirect HTTP traffic to HTTPS.
- The SSL certificate was issued by a trusted certificate authority (CA), and all major web browsers have the CA's root certificate in their trusted certificate stores.
- The SSL certificate includes the correct domain name for the online store.

Given the above information, which of the following steps should be taken to resolve the issue and prevent customers from seeing the security warning?
A: Extend the validity of the current SSL certificate by one year.
B: Obtain a new SSL certificate from the same CA and install it on the web server before the current certificate expires.
C: Remove the automatic redirect from HTTP to HTTPS on the web server.
D: Ask customers to ignore the security warning and proceed to the online store.
E: Replace the SSL certificate with a self-signed certificate.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Network Engineer Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.
