Citrix Architecture & Components Flashcards

Which port carries HDX/ICA traffic when Session Reliability is enabled?

Answer: TCP 2598

Session Reliability wraps ICA in the Common Gateway Protocol on TCP 2598.

Which Delivery Controller feature lets users keep launching resources when the site database is unavailable?

Answer: Local Host Cache

Local Host Cache keeps a copy of the site configuration in LocalDB on each controller so brokering can continue during a database outage.

During a Local Host Cache outage, which resources are unavailable by default?

Answer: Power-managed pooled (random) VDI desktops

Pooled random VDI desktops are not brokered during an LHC outage by default, because their power and assignment state can't be reliably managed.

In a multi-zone site, where must the site database be located?

Answer: In the primary zone

The site database always belongs to the primary zone, while satellite zones contain controllers, VDAs, and hosts.

In Citrix DaaS, which component in each resource location handles communication with the Citrix Cloud control plane?

Answer: Citrix Cloud Connector

Cloud Connectors proxy traffic between the resource location and Citrix Cloud, and Citrix recommends at least two per location for redundancy.

What is the main purpose of a Delivery Group?

Answer: To assign machines from catalogs to users and define what they can access

Delivery Groups assign machines from Machine Catalogs to users and specify the desktops or applications those users receive.

Which Citrix component provides secure remote access to virtual apps and desktops from outside the corporate network?

Answer: Citrix Gateway

Citrix Gateway (NetScaler Gateway) authenticates external users and proxies ICA traffic using STA tickets.
