Medium Mac address and IP on router hop Routers Switches Mac Address Resolution Packet Forwarding	Solve
Refer to the following exhibit: Host A is sending a packet to Host B. 1. What is the source and destination MAC address at point PA? 2. What is the source and destination IP address at point PB? // Option A PA: source MAC - Mac-A PA: destination MAC - Mac-B PB: source IP - 192.168.1.1 PB: destination IP - 192.168.3.1 // Option B PA: source MAC - Mac-A PA: destination MAC - Mac-RA PB: source IP - 192.168.3.3 PB: destination IP - 192.168.3.1 // Option C PA: source MAC - Mac-A PA: destination MAC - Mac-B PB: source IP - 192.168.3.3 PB: destination IP - 192.168.3.1 // Option D PA: source MAC - Mac-A PA: destination MAC - Mac-RA PB: source IP - 192.168.1.1 PB: destination IP - 192.168.3.1
Easy MX Record, DMARC and Email Authentication DNS MX Records DMARC SPF DKIM	Solve
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:report@example.com" 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.

Review the following exhibit: Angelina noticed that the computers on 192.168.10.0/24 network can ping their default gateway. But they found that these computers cannot connect to any remote network resources. Which of the following is the most likely reason for this?
Medium SSL Certificate Expiry SSL/TLS Network Security Ssl/tls	Solve
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.

Read more about the proctoring features.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.
