Scenario: A Citrix Administrator has deployed a Citrix Cloud-managed Citrix Virtual Apps and Desktops Site with one on-premises resource location and two
Cloud Connectors. An on-premises StoreFront server group is used to access published resources. During user acceptance testing, due to adverse weather conditions, network connectivity between the on-premises location and Citrix Cloud was broken for several hours.
Which statement describes what will occur in this scenario?
In the event of a network outage between the on-premises location and Citrix Cloud, Local Host Cache (LHC) functionality ensures that one of the Citrix Cloud Connectors at the resource location is elected as the primary broker. This primary broker uses the LHC to broker new sessions and manage existing HDX connections, thereby maintaining continuity of service during the outage.
A is correct. https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/manage-deployment/local-host-cache.html "The Local Host Cache (LHC) feature allows connection brokering operations in a XenApp or XenDesktop Site to continue when an outage occurs. An outage occurs when the connection between a Delivery Controller and the Site database fails. Local Host Cache engages when the site database is inaccessible for 90 seconds."
A is correct.
"A" is correct Key notes" During an outage, one of the Cloud Connectors is elected to be the primary broker for the resource location. This means that capacity might be diminished during an outage, because LHC will only run on one of the Cloud Connectors at a time.
From my student manual: When an outage happens • The secondary broker starts listening for and processing connection requests. • When the outage begins, the secondary broker does not have current VDA registration data, but as soon as a VDA communicates with it, a registration process is triggered. During that process, the secondary broker also gets current session information about that VDA.
Why not "b", if there is an network faillure between Cloud and On-Premises, how do you do to connect to On-Premises servers via Citrix Cloud ?
==> "An on-premises StoreFront server group is used to access published resources"
I am torn between A and C. Can someone confirm this?
A is correct.
Agreed; the cloud model would be a garbage solution if on-premise workloads were inaccessible anytime that the Internet was temporarily inaccessible.
