CompTIA Network+ (N10-008) — Question 30

A network administrator needs to query the NSs for a remote application. Which of the following commands would BEST help the administrator accomplish this task?

Answer options

• A. dig
• B. arp
• C. show interface
• D. hostname

Correct answer: A

Explanation

The 'dig' command is specifically designed for querying DNS records, making it the best choice for accessing NS records. The 'arp' command is used for mapping IP addresses to MAC addresses, while 'show interface' provides information about the network interfaces on a device and 'hostname' displays or sets the device's hostname, none of which are relevant for querying NS records.
