1Y0-241 Exam Dumps : Deploy and Manage Citrix ADC with Traffic Management

Tricky one, this is for 13.1 and classic still is mandatory for AAA until 2023 (with exceptions on Traffic policy)

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: A. It replaces the date header in the HTTP response with the Citrix ADC system time in a conventional date format.

Short Explanation with reference:

A rewrite action is a set of rules that defines how the Citrix ADC appliance modifies the requests and responses that it processes. A rewrite action can use different parameters, such as target, expression, and pattern, to specify what part of the message to modify and how to modify it. The target parameter specifies the part of the message that is modified, such as the header or the body. The expression parameter specifies the new value that replaces the target. The pattern parameter specifies a string or a regular expression that matches the part of the target that is replaced.

In this scenario, the administrator configured a rewrite action as follows:

add rewrite action sync_date replace http.res.date.sys.time

This rewrite action uses the replace parameter, which replaces the entire target with the expression. The target is http.res.date, which is the date header in the HTTP response. The expression is sys.time, which is a built-in function that returns the Citrix ADC system time in a conventional date format, such as “Wed, 06 Sep 2023 12:45:12 GMT”. Therefore, this rewrite action replaces the date header in the HTTP response with the Citrix ADC system time in a conventional date format. This can be useful for synchronizing the time between the server and the client, or for preventing caching issues.

Therefore, the correct way to interpret this rewrite action is A. It replaces the date header in the HTTP response with the Citrix ADC system time in a conventional date format.
