Networking Fundamentals — Question 34

This question requires that you evaluate the underlined text to determine if it is correct.
The "NTP" value in a resource record indicates a length of time that other DNS servers use to determine how long to cache information for a record before expiring and discarding it.
Select the correct answer if the underlined text does not make the statement correct. Select "No change is needed'' if the underlined text makes the statement correct.

Answer options

• A. TTL
• B. GPS
• C. SOA RR
• D. No change is needed

Correct answer: A

Explanation

The correct answer is A, as 'TTL' (Time to Live) is the correct term that specifies how long DNS servers should cache a record. 'NTP' (Network Time Protocol) is unrelated to DNS caching. 'GPS' (Global Positioning System) and 'SOA RR' (Start of Authority Resource Record) do not pertain to the caching duration of DNS records either.
