Certified Network Defender (CND) — Question 5

Which of the following types of information can be obtained through network sniffing? (Choose all that apply.)

Answer options

• A. DNS traffic
• B. Telnet passwords
• C. Programming errors
• D. Syslog traffic

Correct answer: A, B, D

Explanation

Network sniffing is capable of capturing various types of data packets transmitted over the network. DNS traffic, Telnet passwords, and Syslog traffic are all transmitted in a format that can be intercepted and analyzed, making options A, B, and D correct. However, programming errors are typically not transmitted over the network and thus cannot be captured through sniffing, making option C incorrect.
