Correct Answer: B. SDX

Short Explanation with reference: Citrix ADC SDX is a multi-tenant platform that allows multiple instances of Citrix ADC to run on a single physical appliance. Each instance is isolated from the others and has its own dedicated resources, configuration, and management. This enables service providers and enterprises to offer Citrix ADC as a service to their customers or internal departments, while maintaining security and operational consistency across any deployment12. Citrix ADC VPX, MPX, and CPX are single-tenant platforms that do not support multi-tenancy out of the box3.

Correct Answer: D.

Short Explanation with reference:

A rewrite policy is a set of rules that defines how the Citrix ADC appliance modifies the requests and responses that it processes. A rewrite policy consists of an expression that evaluates to true or false, and an action that specifies what modification to perform. A rewrite action can use the replace_all function to replace all occurrences of a pattern in a string with another string.

In an SSL offload deployment, the Citrix ADC appliance terminates the SSL traffic from the clients and forwards the clear text traffic to the servers. This can cause a problem if the response body from the servers contains URLs that start with “http://”, as they will not match the protocol of the original request, which was “https://”. To fix this problem, the administrator can use a rewrite policy to modify all URLs in the response body from “http://” to “https://”.

The correct policy for this task is D, as it uses the replace_all function to replace all occurrences of “http://” with “https://” in the HTTP response body. The other policies are incorrect, as they either use the wrong pattern or the wrong replacement string. For example, policy A replaces “https://” with “http://”, which is the opposite of what is required. Policy B uses an incorrect escape character (“ ") before the colon (”:“) in both the pattern and the replacement string. Policy C uses a space (” “) instead of a colon (”:") in the replacement string.

- Pol1 has a prio of 90 so it's evaluated first

-gotoPrioExpression NEXT means that it will evaluate next item in the policy list

- Pol2 has a prio of 100, so it"s avaluated after Pol1

Correct Answer: B. Access Control List (ACL)

Short Explanation with reference:

An Access Control List (ACL) is a set of rules that can be used to allow or deny traffic to or from the Citrix ADC appliance1. A Citrix Administrator can use ACLs to restrict access to the NSIP address, which is the IP address used for management purposes2. By default, secure access to the NSIP address is enabled, but it can be disabled by using the -gui option in the CLI or by unchecking the Secure Access only check-box in the GUI2. Alternatively, a Citrix Administrator can also use the allowedManagementInterface parameter to define the list of permitted management interfaces for system users3.

Correct Answer: B. Two-arm

Short Explanation with reference:

A two-arm deployment is a common scenario where the Citrix ADC appliance has two network interfaces, one connected to the DMZ network and the other connected to the internal network1. This allows the appliance to act as a gateway between the two networks and provide load balancing, security, and optimization features for the applications hosted on the internal servers2. A two-arm deployment also provides better isolation and protection for the internal network than a one-arm deployment, where the appliance has only one network interface connected to a switch or router that spans both networks3. A transparent mode is a packet forwarding mode that enables the appliance to act as a Layer 2 device and bridge packets that are not destined for it4. A forward proxy mode is a feature that enables the appliance to act as an intermediary between clients and servers on the internet, caching web content and applying policies. Neither of these modes are relevant for the scenario described in the question.

To put a compression policy into effect, you must bind it either globally, so that it applies to all traffic that flows through the Citrix ADC, or to a specific virtual server, so that the policy applies only to requests whose destination is the VIP address of that virtual server.

By default, compression is disabled on the Citrix ADC. You must enable the feature before configuring it. You can enable it globally so that it applies to all HTTP and SSL services, or you can enable it just for specific services.

Compression is a feature that reduces the size of the data that is exchanged between the Citrix ADC appliance and the clients or servers. Compression can be performed by either the appliance or the servers, depending on the configuration and the availability of the compression feature on both ends. If the servers have the compression feature installed, they can automatically compress the responses before sending them to the appliance, regardless of the ‘Accept Encoding’ header in the requests. This can cause a problem if the appliance is also configured to remove the ‘Accept Encoding’ header from all requests, as it will prevent the appliance from detecting that the responses are already compressed and applying its own compression policy. Therefore, the correct answer is B. The servers are automatically compressing all responses.

A sysadmin is lower than a superuser is terms of access allowed on the appliance. A sysadmin user can perform all Citrix ADC operations with the following exceptions: no access to the Citrix ADC shell, cannot perform user configurations, cannot perform partition configurations, and some other configurations as stated in the sysadmin command policy https://docs.citrix.com/en-us/citrix-adc/current-release/system/authentication-and-authorization-for-system-user/user-usergroups-command-policies.html

Correct Answer: D. Session reuse

Short Explanation with reference:

Session reuse is a feature that allows the Citrix ADC appliance to reuse an existing SSL session between the client and the server, instead of creating a new one for each request1. This reduces the server load, improves response time, and increases the number of SSL transactions per second on an SSL vServer, as the session establishment process involves expensive cryptographic operations2. Session reuse is enabled by default on the Citrix ADC appliance, but it can be disabled or configured with different options1.

When you enable the USIP address mode of a NetScaler appliance, the appliance forwards each packet to the appropriate back end server with the client IP address. https://support.citrix.com/article/CTX121974
