B.

GTM System cannot resolve a host name that is not a Wide-IP.

C.

It comes from the database of previously cached name resolutions.

D.

It comes from a zone transfer initiated when the request was received

Which statement about root DNS servers is true?

A.

Root servers have databases of all registered DNS servers.

B.

Root servers have databases of the DNS servers for top-level domains.

C.

Root servers have databases of DNS servers for each geographical area. They directrequests
to appropriate LDNS servers.

D.

Root servers have databases of commonly accessed sites. They also cache entries
foradditional servers as requests are made.

What is the advantage of specifying three load balancing methods when load balancing within
pools?

A.

Specifying three methods allows the GTM System to use all three methodssimultaneously.

B.

Specifying three methods allows the GTM System to choose the optimal method for eachname
resolution.

C.

Specifying three methods allows the GTM System alternate methods if insufficient data
isavailable for other methods.

D.

Specifying three methods allows the GTM System to rotate between the three methods sothat
no one method is used too often.
