CCA Citrix Virtual Apps & Desktops Administration 2 — Questions and Answers
Question 1: The Site database becomes unavailable, yet users can still launch resources. Which feature makes this possible?
- Session Reliability
- Local Host Cache (Correct answer)
- Connection Leasing via StoreFront
- Auto Client Reconnect
Correct answer: Local Host Cache
Local Host Cache keeps a LocalDB copy of Site configuration on each Delivery Controller so brokering continues during a Site database outage.
Question 2: What is the default TCP port the Citrix License Server uses for license checkout requests from a Delivery Controller?
- 1494
- 8083
- 27000 (Correct answer)
- 2598
Correct answer: 27000
The license server manager (lmadmin) listens on TCP 27000 by default, and the Citrix vendor daemon uses 7279.
Question 3: An administrator wants a VDA to find its Delivery Controllers without manual registry edits and to pick up controller changes automatically. Which registration method does Citrix recommend?
- Auto-update (Correct answer)
- Registry-based ListOfDDCs
- Active Directory OU-based discovery
- Hosts file entries
Correct answer: Auto-update
Auto-update is enabled by default and keeps the VDA's list of controllers current after its first successful registration.
Question 4: A Delivery Group machine is placed in maintenance mode. What is the effect?
- All current sessions are logged off at once
- The machine is shut down at once
- The machine accepts no new connections, but existing sessions keep running (Correct answer)
- The machine is removed from its machine catalog
Correct answer: The machine accepts no new connections, but existing sessions keep running
Maintenance mode blocks new connections and leaves existing sessions running so the machine can be drained for updates.
Question 5: Which Citrix policy always has the lowest priority and applies to all objects when no filters are set?
- The policy with priority 1
- The Unfiltered policy (Correct answer)
- The highest-numbered custom policy
- The Default HDX policy
Correct answer: The Unfiltered policy
The built-in Unfiltered policy always has the lowest priority and is overridden by any conflicting filtered policy.
Question 6: A help desk operator needs to watch and help with a user's live session from Citrix Director. Which feature should they use?
- Session Recording playback
- Shadow (Correct answer)
- Reset Profile
- Logon Duration
Correct answer: Shadow
Shadowing in Director uses Windows Remote Assistance so an administrator can view or control a user's active session.
Question 7: Which ports does a VDA use for ICA traffic with and without Session Reliability enabled?
- 443 with Session Reliability, 80 without
- 2598 with Session Reliability, 1494 without (Correct answer)
- 1494 with Session Reliability, 2598 without
- 8080 with Session Reliability, 3389 without
Correct answer: 2598 with Session Reliability, 1494 without
ICA uses port 1494, and Session Reliability wraps ICA in CGP on port 2598.
