Advanced Sample Questions
What is the main purpose of using Load Balancing in Citrix ADC?
- A) To increase the speed of a single server
- B) To distribute traffic evenly across multiple servers
- C) To prevent server crashes
- D) To increase the security of a single server
Answer: B) To distribute traffic evenly across multiple servers
Explanation: Load balancing is a technique used in computer networking to distribute network traffic evenly across multiple servers. This helps to ensure that no single server becomes overwhelmed with traffic, which can lead to slowdowns or crashes.

What is the purpose of a Content Switching virtual server in Citrix ADC?
- A) To redirect incoming traffic to different servers based on specific conditions
- B) To balance the load between servers
- C) To encrypt incoming traffic
- D) To increase the speed of a single server
Answer: A) To redirect incoming traffic to different servers based on specific conditions
Explanation: A Content Switching virtual server in Citrix ADC is used to redirect incoming traffic to different servers based on specific conditions, such as the URL or the type of device making the request. This allows administrators to ensure that requests are directed to the most appropriate server based on the specific needs of each request.
Reference: https://docs.citrix.com/en-us/citrix-adc/13/content-switching/
What is the purpose of SSL offloading in Citrix ADC?
- A) To reduce the load on the servers
- B) To encrypt incoming traffic
- C) To decrypt incoming traffic
- D) To increase the security of a single server
Answer: C) To decrypt incoming traffic
Explanation: SSL offloading in Citrix ADC is the process of decrypting incoming SSL (Secure Socket Layer) traffic before it reaches the servers. This reduces the load on the servers by allowing them to handle only unencrypted traffic. By offloading the SSL decryption process to the ADC, the servers are free to perform other tasks, such as serving web pages or processing database requests.
Reference: https://docs.citrix.com/en-us/citrix-adc/13/ssl/
What is the purpose of Global Server Load Balancing (GSLB) in Citrix ADC?
- A) To balance the load between servers in different locations
- B) To redirect incoming traffic to different servers based on specific conditions
- C) To encrypt incoming traffic
- D) To increase the speed of a single server
Answer: A) To balance the load between servers in different locations
Explanation: Global Server Load Balancing (GSLB) is a technique used in computer networking to balance the load between servers located in different geographic locations. This helps to ensure that users are directed to the closest server, which can result in faster response times and improved performance.

What is the main function of AppFirewall in Citrix ADC?
- A) To balance the load between servers
- B) To encrypt incoming traffic
- C) To protect against malicious traffic
- D) To increase the speed of a single server
Answer: C) To protect against malicious traffic
Explanation: AppFirewall in Citrix ADC is a feature that provides protection against malicious traffic by examining incoming traffic and blocking traffic that matches defined security rules. This helps to ensure the security of web applications and prevents attacks such as SQL injection or cross-site scripting.
Reference: https://docs.citrix.com/en-us/citrix-adc/13/appfirewall/

- A) To redirect incoming traffic to different servers based on specific conditions
- B) To balance the load between servers
- C) To perform actions based on incoming requests
- D) To increase the speed of a single server
Answer: C) To perform actions based on incoming requests
Explanation: A Responder policy in Citrix ADC is a set of rules that allow administrators to perform specific actions based on incoming requests. For example, a responder policy could be used to redirect a request to a different URL or to display a custom error page in response to a specific type of request.
Reference: https://docs.citrix.com/en-us/citrix-adc/13/responder/
What is the purpose of the Rate Limiting feature in Citrix ADC?
- A) To limit the number of requests made to a server in a given time period
- B) To balance the load between servers
- C) To encrypt incoming traffic
- D) To increase the speed of a single server
Answer: A) To limit the number of requests made to a server in a given time period
Explanation: The Rate Limiting feature in Citrix ADC allows administrators to limit the number of requests made to a server in a given time period. This helps to prevent overloading of the server and to ensure that it is able to respond to requests in a timely manner.
Reference: https://docs.citrix.com/en-us/citrix-adc/13/rate-limiting/
What is the purpose of a URL Transformation policy in Citrix ADC?
- A) To modify the URL of incoming requests
- B) To balance the load between servers
- C) To encrypt incoming traffic
- D) To increase the speed of a single server
Answer: A) To modify the URL of incoming requests
Explanation: A URL Transformation policy in Citrix ADC allows administrators to modify the URL of incoming requests. For example, a URL Transformation policy could be used to remove specific parameters from a URL or to add a specific string to the URL. This can be useful in situations where the format of the URL needs to be changed to meet the requirements of a particular application.
Reference: https://docs.citrix.com/en-us/citrix-adc/13/url-transformation/
What is the purpose of the Content Filtering feature in Citrix ADC?
- A) To block access to specific types of content
- B) To balance the load between servers
- C) To encrypt incoming traffic
- D) To increase the speed of a single server
Answer: A) To block access to specific types of content
Explanation: The Content Filtering feature in Citrix ADC allows administrators to block access to specific types of content, such as websites or URLs that contain inappropriate or malicious content. This helps to ensure the security of a network and to prevent users from accessing content that may pose a threat to the network.
