CCA Network Configuration 5 — Questions and Answers
Question 1: What is the default Session Reliability timeout before a disconnected session is fully dropped to Auto Client Reconnect?
- 30 seconds
- 180 seconds (Correct answer)
- 300 seconds
- 60 seconds
Correct answer: 180 seconds
The default Session Reliability timeout is 180 seconds (3 minutes).
Question 2: Which feature allows multiple TCP ports to carry different ICA virtual channel priorities for QoS?
- Adaptive Transport
- Session Reliability
- Multi-Port Policy (Correct answer)
- Secure ICA
Correct answer: Multi-Port Policy
Multi-Port Policy assigns additional ports to virtual channel priorities for network QoS.
Question 3: An administrator needs VDAs to locate Delivery Controllers automatically without manual configuration. Which method relies on Active Directory?
- DHCP option 66
- Policy-based ListOfDDCs registry
- Auto-update only
- AD-based discovery via OU (Correct answer)
Correct answer: AD-based discovery via OU
Active Directory OU-based discovery lets VDAs locate Controllers through objects published in AD.
Question 4: What is the recommended method for VDAs to obtain the Controller list after initial registration?
- Auto-update (Correct answer)
- Manually editing hosts files
- DNS round robin only
- Static routes
Correct answer: Auto-update
Auto-update is enabled by default and keeps the VDA's Controller list current automatically.
Question 5: Which DNS-related issue most commonly causes VDA registration failures?
- Incorrect MX records
- Incorrect forward or reverse lookups for Controller FQDNs (Correct answer)
- Missing CNAME for the License Server
- Expired DHCP leases on StoreFront
Correct answer: Incorrect forward or reverse lookups for Controller FQDNs
VDA registration relies on Kerberos, which requires accurate DNS name resolution for Controllers.
Question 6: In a StoreFront deployment behind Citrix Gateway, what must the Callback URL resolve to?
- The VDA subnet gateway
- The Delivery Controller IP
- A Gateway VIP reachable from StoreFront (Correct answer)
- The License Server FQDN
Correct answer: A Gateway VIP reachable from StoreFront
StoreFront uses the Callback URL to contact Gateway for SmartAccess and authentication verification.
Question 7: Which time synchronization issue can break Delivery Controller and VDA communication?
- NTP using UDP 123
- A time zone set to UTC
- Daylight saving time enabled
- Clock skew greater than 5 minutes between machines (Correct answer)
Correct answer: Clock skew greater than 5 minutes between machines
Kerberos rejects authentication when clock skew exceeds the default 5-minute tolerance.
