CCA Citrix ADC & Gateway Configuration 1 — Questions and Answers
Question 1: What is the primary role of Citrix ADC (formerly NetScaler) in a Citrix Virtual Apps and Desktops deployment?
- Database management and replication
- Application delivery controller providing load balancing, SSL offloading, and traffic management (Correct answer)
- Desktop hypervisor managing virtual machines
- User profile management and roaming
Correct answer: Application delivery controller providing load balancing, SSL offloading, and traffic management
Citrix ADC acts as an application delivery controller, optimizing and securing application traffic through load balancing, SSL offloading, and traffic management.
Question 2: Which Citrix ADC feature decrypts SSL/TLS traffic at the ADC and forwards unencrypted traffic to backend servers, reducing their processing load?
- Content Switching
- Global Server Load Balancing (GSLB)
- SSL Offloading (Correct answer)
- AppFlow
Correct answer: SSL Offloading
SSL Offloading (SSL termination) decrypts HTTPS traffic at the ADC so backend servers do not need to perform the CPU-intensive decryption themselves.
Question 3: Which protocol and method does Citrix Gateway primarily use to provide secure remote access to internal Citrix resources?
- FTP over SSH tunneling
- SNMP over UDP
- SSL/TLS with ICA proxy (Correct answer)
- IPSec site-to-site VPN
Correct answer: SSL/TLS with ICA proxy
Citrix Gateway uses SSL/TLS with ICA proxy to securely tunnel ICA traffic from remote users to internal Citrix Virtual Apps and Desktops sessions.
Question 4: In a Citrix ADC High Availability (HA) pair, what happens automatically when the primary node becomes unavailable?
- An administrator must manually promote the secondary node
- The secondary node takes over as primary and begins processing traffic (Correct answer)
- All active user sessions are terminated and must reconnect
- The HA pair enters a suspended state until the primary recovers
Correct answer: The secondary node takes over as primary and begins processing traffic
In an ADC HA pair, the secondary node automatically detects the primary failure and promotes itself to primary, continuing to process traffic with minimal interruption.
Question 5: Which Citrix ADC object type represents a single backend application server and its associated port?
- Virtual Server
- Service (Correct answer)
- Monitor
- Policy
Correct answer: Service
A Service in Citrix ADC represents a backend server (defined by IP address and port) that the ADC forwards client traffic to.
Question 6: What is the default port on which a Citrix Gateway virtual server listens for incoming HTTPS client connections?
- 80
- 443 (Correct answer)
- 8080
- 1494
Correct answer: 443
Citrix Gateway virtual servers listen on port 443 by default, which is the standard HTTPS port used for secure web and ICA proxy connections.
Question 7: Which Citrix ADC component periodically sends probes to backend services to verify they are online and healthy before forwarding client traffic?
- Content Switching vServer
- Responder Policy
- Health Monitor (Correct answer)
- AppExpert Template
Correct answer: Health Monitor
Health Monitors (e.g., HTTP, TCP, PING monitors) probe backend services at configurable intervals and mark them DOWN if they fail to respond correctly, preventing traffic from being sent to unhealthy servers.
