Your customer has an application on VNX File storage. The customer allocated the storage using Manual Volume Management in order to achieve the best performance. The customer noted that the file system used up all of the storage from the File LUNs even though the size of the file system is much less than the total of the File LUNs used.
Why was all of the storage used when the file system was created?
A. The customer did not change the default_slice_flag to "yes" when creating the file poolA VMware Administrator has received numerous reports from his users about performance degradation. The administrator believes that your storage design on the VNX is the reason for the symptoms.
You ask the administrator for an esxtop analysis of the affected ESXi server. When you examine the report and notice that the value on the Load Average Line is 2.00.
What would you report back to the administrator?
A. The ESXi server is overloaded. The VMs should be redistributed or physical CPUs added.A customer is designing an environment that utilizes thin LUNs on a pool. The customer makes capacity calculations before they create the thin LUNs, and determine that three thin LUNs are required. After the customer creates them they experience a capacity shortage.
How much overhead should the customer have calculated into the usable capacity for each thin LUN?
A. 500 MBA Customer needs a RAID configuration that can maintain 650 host IOPs. The workload has a profile of 90% reads and 10% writes. The customer is also trying to reduce the amount of drives to buy. What RAID configuration would meet the customer's requirements?
A. 15K SAS Drives in a RAID 1/0 2+2Why is it important for Pool LUNs to always have the same Default SP owner and Default Allocation owner?
A. So they do not pass data across the CMI bus.A clone source LUN is 1 TiB in size. It performs 450 random 8 KiB IOPs with a 2:1 R/W ratio. As part of ongoing testing, the clone is fractured for five minutes and then resynchronized. The testing is performed every hour. How much data (to the nearest GiB) is read from the source LUN as part of the resynchronization process?
A. 3 GiBWhat would happen if both watermarks are lowered in a bursty workload environment with EMC VNX?
A. Increases the cache's number of free pages beyond the high watermarkA customer implemented SAN Copy with default settings to create full copies of 60 DMX array volumes on a VNX storage system. After several hours, they determine that the process is taking much longer than expected.
Which setting change on the storage system will improve performance?
A. Disable the CMI channel on the destination storage systemA VNX block-only customer is requesting a performance evaluation of their array. The storage administrator asks you what files you will need to perform the assessment. The customer does not have Analyzer licensed. How do you respond?
A. Request the .naz files and SP collectsA Customer is planning to build a VMware DTaaS environment on a VNX array. The customer is deciding what type of VM replicas would be acceptable in their environment. It needs to have a small footprint and contain frequently accessed data on SSDs drives. What should be recommended?
A. Link ClonesNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job. But how to prepare for the exam effectively?
