CCA Network Configuration 4 — Questions and Answers
Question 1: In a Citrix Cloud deployment, which network communication is required from Cloud Connectors to Citrix Cloud?
- Inbound HTTPS on port 443
- Inbound TCP 1494
- Outbound HTTPS on port 443 (Correct answer)
- Outbound UDP 2598
Correct answer: Outbound HTTPS on port 443
Cloud Connectors only need outbound 443 to Citrix Cloud; no inbound ports are required.
Question 2: What does the Rendezvous protocol allow VDAs to do in Citrix DaaS?
- Register directly to the on-premises License Server
- Replace DNS resolution for VDAs
- Bypass StoreFront authentication
- Connect HDX sessions through the Gateway Service without traffic passing through Cloud Connectors (Correct answer)
Correct answer: Connect HDX sessions through the Gateway Service without traffic passing through Cloud Connectors
With Rendezvous, the VDA connects outbound directly to the Citrix Gateway Service, bypassing the Cloud Connectors for HDX traffic.
Question 3: An administrator configures load balancing for multiple StoreFront servers on Citrix ADC. Which persistence type is recommended?
- Cookie-based or source IP persistence (Correct answer)
- SSL session ID persistence only
- Rule-based DNS persistence
- No persistence
Correct answer: Cookie-based or source IP persistence
Citrix recommends cookie insert or source IP persistence so users stay on the same StoreFront server.
Question 4: Which protocol do Delivery Controllers use to communicate with the Site SQL Server database by default?
- UDP 53
- TCP 1433 (Correct answer)
- TCP 389
- TCP 80
Correct answer: TCP 1433
SQL Server's default instance listens on TCP 1433.
Question 5: Which port does the Citrix License Server use for vendor daemon communication by default?
- TCP 1494
- TCP 8082
- TCP 7279 (Correct answer)
- TCP 27000
Correct answer: TCP 7279
The Citrix vendor daemon uses TCP 7279, while 27000 is used by the license manager daemon.
Question 6: Users report HDX sessions disconnect briefly on Wi-Fi but resume without re-authenticating. Which feature provides this behavior?
- Workspace Control
- Adaptive Transport
- Auto Client Reconnect only
- Session Reliability (Correct answer)
Correct answer: Session Reliability
Session Reliability keeps the session window open and buffers traffic during brief network interruptions.
Question 7: Which policy setting controls whether HDX uses EDT with fallback to TCP?
- HDX Adaptive Transport (Correct answer)
- ICA listener port number
- Multi-Port Policy
- Session Reliability timeout
Correct answer: HDX Adaptive Transport
HDX Adaptive Transport, set to Preferred, uses EDT when available and falls back to TCP.
