How can a Citrix Administrator guarantee the availability of resource locations in a Citrix Cloud deployment?

To guarantee the availability of a resource location, Citrix's official best practice is to deploy a minimum of two Cloud Connectors. This N+1 redundancy ensures that if one Cloud Connector is offline for maintenance or fails unexpectedly, the other active Cloud Connector(s) can maintain the vital communication link between the resources (e.g., VDAs, StoreFront) and the Citrix Cloud management plane. Citrix Cloud services are designed to automatically distribute traffic and handle failover across all available connectors within a resource location, thus preventing a single point of failure and ensuring continuous service availability.

A. Citrix Cloud automatically load-balances traffic across available connectors. Using a Citrix ADC for this core function is not the standard or required method for ensuring availability.
C. This describes a manual, reactive recovery process, not a high availability solution. It would result in significant downtime while a new connector is deployed.
D. Deploying a single Cloud Connector creates a single point of failure, which directly contradicts the goal of guaranteeing availability.

1. Citrix Cloud Documentation, "Citrix Cloud Connector Technical Details," High availability section.

"To ensure high availability and to manage the load, install multiple Cloud Connectors in each resource location. Citrix recommends at least two Cloud Connectors in each resource location to ensure a highly available connection with Citrix Cloud. If one Cloud Connector is unavailable for any reason, the other Cloud Connectors can maintain the connection."

2. Citrix Cloud Documentation, "Install Cloud Connectors," Before you install section.

"For high availability, Citrix recommends installing at least two Cloud Connectors in each resource location you create. This redundancy means that if one Cloud Connector becomes unavailable, Citrix Cloud can still communicate with your resource location."

3. Citrix Tech Zone, "Reference Architecture: Citrix DaaS," Resource Location > Cloud Connector section.

"For redundancy and high-availability, Citrix recommends using at least two Cloud Connectors for each resource location. If one Cloud Connector is unavailable, the other Cloud Connectors can maintain the connection to Citrix Cloud."
