Question 70

Scenario: A Citrix Architect needs to support a Citrix Virtual Apps and Desktops environment with 2 data centers. App Layering is being used to create layered images that are used by the Virtual Delivery Agent (VDA) machines in both data center locations. To comply with disaster recovery (DR) requirements, administrators must be able to modify and deploy layered images from either data center if needed.

Which statement correctly describes the process that the architect must follow to meet the requirements?

All required layers should be exported from the first Enterprise Layer Manager using the hypervisor hosting the machine, then imported to the hypervisor resource pool in the secondary data center.

All required layers should be copied from the first Enterprise Layer Manager to the second Enterprise Layer Manager using Microsoft Distributed File System Replication (DFSR)

All required layers should be exported from the first Enterprise Layer Manager to an SMB file share, and then imported into the second Enterprise Layer Manager.

All required layers should be copied from the first Enterprise Layer Manager to the second Enterprise Layer Manager using RoboCopy commands

Correct Answer: C

To support a Citrix Virtual Apps and Desktops environment in a disaster recovery scenario with modification and deployment capabilities from either data center, the process involves exporting the required layers from the first Enterprise Layer Manager to an SMB file share and then importing them into the second Enterprise Layer Manager. This approach ensures that all layered images remain synchronized and accessible from both data centers, meeting the disaster recovery requirements efficiently.

TerrifiedchipmunkOption: C

Extract from the course documents: Layers can be shared across composite images (so long as the underlying OS is consistent). It is possible to export all your layers from one ELM appliance to a Windows share, and then import them to another appliance. This process could be used to keep two appliances in separate physical Sites in sync. C is correct!

C should be correct by: https://docs.citrix.com/en-us/tech-zone/design/reference-architectures/app-layering.html#dual-appliance-model

d0bermannnOption: C

C is correct, SMB must be used

vipjasonOption: B

This one is tricky as the citrix doc referenced below also states that DFSR can be used, and its pretty obvious that the folks at Citrix who create these tests lack "real-world experience" as DFSR is not suited for large files as its not block based.

jdstroyOption: C

Kada1111 is right! C is correct!
