Question

You have a server named DNS1 with a zone named csmtech.local. Several computers use DHCP for IP address assignment, and their IP addresses change often. Client computers are often unable to communicate with some of these computers until they clear their local DNS caches. What can you do to reduce the problem

Answer 1

A DNS cache is used to maintain the records of visitors. As the cache full, client computers are unable to communicate other computers on the network. To resolve this issue, we set lower value of DNS zone minimum TTL.

Step-by-step explanation:

DNS zone minimum TTL

This is the value that is used at minimum values to perform smooth effect of changes. This value should not be too low or 0.

There TTL means time to live.

TTL should be lower so that, cache cannot store data for too much time.
