Question 83

Scenario: A Citrix Architect is designing a new Citrix Virtual Apps and Desktops environment. The Site will contain two Delivery Controllers. All machines are running on a single hypervisor platform. As part of the deployment, management has advised they want a database high-availability (HA) solution to protect the environment against the loss of a physical server.

Additional considerations for the SQL HA:

✑ Downtime for Citrix administrative functions should be minimized.

✑ Additional hardware or resources should be minimized.

✑ Limited knowledge available to configure and maintain SQL infrastructure.

Which HA configuration should the architect use for this deployment?

    Correct Answer: B

    Given the requirements to minimize downtime for Citrix administrative functions and limit additional hardware or resources, VM-Level High Availability (HA) is the most suitable option. It ensures high availability at the hypervisor level, protecting against the loss of a physical server. Moreover, this solution does not require additional SQL servers, configuration, or licensing, which aligns with the need to minimize additional resources and the requirement of limited knowledge for maintaining the SQL infrastructure.

Discussion
UnknownUser060606Option: B

« Downtime for the Citrix administrative » functions is key too, so B. LHC won’t fulfill this requirement.

Aurelien586Option: A

Single Hypervisor Platform so It's A

vipjasonOption: A

I would have to say A, but it would be better if these tests were based on real-world scenarios rather then trying to trick the us by making us select the least absurd answer.

flo_praOption: A

In the coursebook, LHC is mentioned as an HA feature (pages 511-512). And it says for VM-Level-HA: "Because a full copy of a machine has to be completed, this option may take longer to complete than other SQL HA methods causing longer down times". For SQL methods it says that requires additional SQL servers, configuration and licensing.

steveleek2Option: B

LHC is also just a feature and not a specified HA solution per https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/1912-ltsr/technical-overview/databases.html VM-Level HA is the best available solution.

jdstroyOption: B

VM-level HA implements the HA at hypervisor level. The best solution under given conditions is B I guess https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/1912-ltsr/technical-overview/databases.html

jdstroy

...one condition is "protect against the loss of a physical server". LHC won't solve this.
