CWS-415 Citrix Virtual Apps and Desktops 7 Assessment, Design and Advanced Configuration Quiz Questions and Answers

Answer :
  • Add 2 StoreFront servers to separate server groups and configure subscription synchronization

Explanation :

It is recommended to configure separate server groups across datacenters spanning multiple geo-locations. Also, configure subscription synchronization between server groups of New York and Japan Storefront servers to allow for favorite synchronization. As favorites are updated frequently by users, this can be scheduled during off peak hours to reduce the bandwidth consumption. Optimal Gateway feature requires the ADC Gateway to be configured which is not specified here. Also, standalone server will not help this scenario.
Answer :
  • Thin provisioning
  • Intellicache

Explanation :

Thin Provisioning allows for utilizing existing storage space for workloads which occupies only the space required at present and grows as per the need instead of entirely committing the stoarge space up front. IntelliCache features allows to cache the PVS steem data on hypervisor's host memory and hence reduces the network utilization for cached data needs.
Answer :
  • Virtual Delivery Agent (VDA) machines in Zone 2 will register within the Primary Zone

Explanation :

VDAs in Satellite zone will register only with the Delivery Controllers in that zone Or will register with the Delivery Controllers of Primary Zone, if the respective Stellite Zone Delivery Controlers are unavailable for registration. The question here specifies a failed Delivery Controller which means even LHC will not be functional during that scenario.
Answer :
  • VM-Level HA

Explanation :

Local Host Cache mode does not allow administrative functions during the outage of the database. SQL Always On and SQL mirroring though a supported configuration for CVAD deployment, it will require extensive SQL expertise for the configuration. VM-Level HA allows for all the stated requirements as it is configured at the hypervisor cluster level.
Answer :
  • MAC-based forwarding (MBF)

Explanation :

MAC-based forwarding improves performance of ADC by avoiding multiple ARP or route table lookup when forwarding the packet, When MBF is enabled it cache the MAC address of uplink router which forwarded the requestto ADCand when reply is received it is passed t osame router who sent client requestwithout going through any route lookup.
Answer :
  • Provision new resources in Japan’s resource location

Explanation :

The slowness and degraded performance is due to the latency between the Japan user loaction and the resource location which is in Germany. To overcome this, the resurces should be deployed to a location near to Japan users. Other options provided do not help in resolving the slowness issue in this scenario.
Answer :
  • On-premises Citrix Gateway with Citrix Cloud-hosted Workspace

Explanation :

To meet the stated security requirement, use an On-Premise Citrix Gateway paired with Citrix Cloud hosted Workspace. The initial authentication and enumeration will pass through the Workspace and Cloud Connector combination but all HDX Session will pass through Gateway on Premise setup in the same country.
Answer :
  • Citrix Virtual Apps and Desktops Service and on-premises workload

Explanation :

Citrix Cloud service is managed by Citrix thus reducing the administratve overahead and complexity for the inexperienced IT team. On Premise resource location means VDAs hosting applications reside in the same datacenter as that of databases meeting the stated latency requirement.
Answer :
  • Block access to the DR data center, terminate/drain existing sessions in the DR data center, complete replication to the primary data center, configure replication back to the DR data center, and enable access in the primary data center.

Explanation :

The right approach for disaster recovery is : Block access to functional datacenter which has failed and has existig connections, Terminate existing Connections, Enable replication to recovered Primary/DR datacenter and enable access to the recovered Primary/DR datacenter.
