Which two statements are true about resolvers in the DNS hierarchy? (Choose two.)

The resolvers attempt to resolve client queries by using the records that the resolvers maintain in their zone database files.

The DNS server queries the resolvers to translate the domain name to an IP address.

There can be only one resolver in a DNS zone.

Resolvers may be configured on DNS clients.

The DNS server uses the resolver to forward the name resolution request to another DNS server.

. The TCP Protocol Interpreter process verifies the transmitted data at source and destination.
