QUESTION 20 Scenario: An entire Shift of workers arrives at the office at 09:00 AM two thousand users turn on their thin client terminals and launch the line of business application within a ten-minute timeframe. The resultant traffic is so intense that it takes 15-20 minutes until everybody is able to start working. How can the administrator prevent this issue from affecting the user experience? A. B. C. D. Implement a NetScaler load balancer to distribute the XML traffic Configure a Pre-lunch application to be started for users before they arrive. Upgrade the XenApp farm database server to a cluster with real time replication. Configure additional zone data collectors to manage the numerous concurrent logins.
Answer: B Section: (none) Explanation/Reference: Explanation: netscaler load balances the connections of webinterfaceservers and xml servers, but that doesn't help with the launch time if everyone connects at the same time, probably the profile loading will cause this, with pre launch the sessions can be started before the user connects and therefore they won't have to wait that long
Exam D QUESTION 1 Scenario: Users complain that first thing in the morning they receive errors when trying to launch their application and have to re-try many times. At other times of the day, there are NO issues? What could be causing the morning issue? A. B. C. D. A load throttling load evaluator is limiting the number of concurrent logons. A scheduling to load evaluator is restricting the maximum server load at this time. A server load evaluator is limiting the number of concurrent users in the farm. An application user load evaluator is limiting the maximum number of users allowed to run the application.
Answer: A Section: (none) Explanation/Reference: Explanation: if the impact on load throttling is set too high the server reports full load when too many users connect at the same time. With too less servers they all can be fully loaded at prime time in the morning
