Question 5 – MCSA 70-411

PRIOR QUESTION

Windows servers use round robin for which of the following reasons? (Choose two.)

Select the correct answer(s):

A) Used by DNS servers to share and distribute network resource load.
B) Used by AD servers to share and distribute network resource load.
C) DNS uses round robin to rotate the order of RR data returned in query answers where multiple RRs of the same type exist.
D) To order of the response for these queries is based on a static ordering of RRs.

The answer is at the very bottom of the page because we wanted to give you a chance to think about first:)

Explanation: Round robin is a local balancing mechanism used by DNS servers to share and distribute network resource loads. Round Robin will rotate all resource record (RR) types contained in a query answer if multiple RRs are found. DNS uses round robin to rotate the order of RR data returned in query answers where multiple RRs of the same type exist for a queried DNS domain name. This feature provides a simple method for load balancing client use of Web servers and other frequently queried multi-homed computers. Only when round robin is disabled for a DNS server, the order of the response for these queries is based on a static ordering of RRs in the answer list as they are stored in the zone.

Exam Objective: This question addresses 70-411 main objective 4: “Configure a Network Policy Server (NPS) infrastructure” (this objective is listed at 15-20% of the total 70-411 exam). The sub-objective is 4.3 “Configure Network Access Protection (NAP).”

Question 5 – Correct answer(s): A) Used by DNS servers to share and distribute network resource load & C) DNS uses round robin to rotate the order of RR data returned in query answers where multiple RRs of the same type exist.
