NEW QUESTION 2

Which two statements are true for Predictive DRS? (Choose two.)

• A. It balances resource utilization for virtual machines with unpredictable utilization patterns.
• B. It integrates DRS with vRealize Operations Manager to balance workloads for virtual machines before resource utilization spikes occur.
• C. It balances resource utilization based on a threshold’s algorithm that runs each night.
• D. It determines the best placement and balance of virtual machines based on a threshold’s algorithm that runs each night in vCenter Server 6.5 Database.

Answer: BC

Explanation:
Predictive DRS
Predictive DRS is a new feature that leverages the predictive analytics of vRealize Operations Manager with the powerful resource scheduler algorithm of vSphere DRS. Together, these two products enable workload balancing for certain VMs before resource utilization spikes occur, potentially eliminating a great amount of resource contention that might have occurred in the past. vRealize Operations Manager runs its dynamic thresholds algorithm nightly against the VMs on which it collects data. These dynamic thresholds create forecasted metrics for the future utilization of the VMs. The metrics are then passed to vSphere DRS to determine the best placement and balance of VMs before resource utilization spikes occur. Predictive DRS helps prevent resource contention on hosts that run VMs with predictable utilization patterns.

NEW QUESTION 13

ESXi hosts with 10Gbps network cards are attached to a distributed switch. The administrator has upgraded to NIOC3 and wants to allow vMotion traffic to use as much bandwidth as possible but must ensure that other services always have sufficient bandwidth.
How can this be done?

• A. Configure shares on the distributed switch for the vMotion traffic type.
• B. Configure limits on the distributed switch on the on vMotion traffic type.
• C. Associate vMotion traffic with a network resource pool and use CoS tagging.
• D. Set shares on user-defined network resource pool and associate it with vMotion traffic.

Answer: A

Examine the LUN properties that are shown in the exhibit. Which action should be taken to utilize all active paths?

• A. Change PSP to Most Recently Used
• B. No action require
• C. All paths are already utilized.
• D. Change PSP to Fixed.
• E. Change PSP to Round Robin.

Answer: D

Explanation:
The host uses an automatic path selection algorithm rotating through all active paths when connecting to active-passive arrays, or through all available paths when connecting to active-active arrays. RR is the default for a number of arrays and can be used with both active-active and active-passive arrays to implement load balancing across paths for different LUNs.
