1Y0-312 Performance and Scalability Optimization Practice Question
An administrator is deploying Citrix Profile Management for a pooled VDI catalog on shared storage. Users report that logons take over 60 seconds and the storage array shows heavy random read activity during morning logon storms. Which configuration in the Profile Management policy should the administrator enable to reduce this I/O load?
⚠ Common exam trap
The trap here is assuming that any profile-related policy that reduces logoff time, such as Active write back, will also reduce logon I/O.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Profile streaming.
Profile streaming is designed to reduce logon I/O by not copying the entire profile at logon. It retrieves files on demand, which lowers random read pressure on shared storage and speeds logons during a boot or logon storm. Active write back, Cloud Connector caching, and AppData redirection do not defer profile reads and therefore do not solve the described bottleneck.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Citrix Cloud Connector caching.
Why it's wrong here
Cloud Connector caching relates to connectivity between on-premises resources and Citrix Cloud, not to how profile data is read from the user store. It has no mechanism to defer or batch profile file reads, so it cannot reduce the random read I/O causing the slow logons in this scenario.
- ✗
Enable Folder Redirection for AppData.
Why it's wrong here
Folder Redirection moves specific folders such as AppData to a network share. Redirecting AppData typically increases logon and application launch I/O to the same shared storage, compounding the random read problem rather than reducing it for pooled VDI users with shared profiles.
- ✗
Enable Active write back.
Why it's wrong here
Active write back flushes modified profile files back to the user store during the session rather than only at logoff. While it reduces logoff time, it does not reduce the random read I/O at logon and can actually increase storage traffic during the session, so it fails to address the morning logon storm described.
- ✓
Enable Profile streaming.
Why this is correct
Profile streaming defers copying files from the user store until they are actually accessed, so logon only retrieves the profile structure and a small subset of files. This dramatically reduces random reads on shared storage during logon storms, shortening logon time for pooled VDI users whose profiles reside on a network share.
