"if you enable multiple IP responses (MIR), the Citrix ADC appliance sends the best GSLB service as the first record in the response and adds the remaining active services as extra records. "

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: D. Virtual MAC

Short Explanation with reference:

Virtual MAC (VMAC) is a feature that allows the Citrix ADC appliance to use a common MAC address for both the primary and secondary units in a high availability (HA) pair1. This prevents the upstream router from having to update its ARP table when a failover occurs, as the MAC address of the active unit remains unchanged2. VMAC can be enabled or disabled by using the -vmac option in the CLI or by checking or unchecking the Enable VMAC check-box in the GUI1. Therefore, the correct answer is D. Virtual MAC.

Correct Answer: A. Set the primary Citrix ADC to stay primary in the Configure HA Node settings and B. Set the secondary Citrix ADC to stay secondary in the Configure HA Node settings.

Short Explanation with reference:

When configuring a Citrix ADC high availability (HA) pair, the administrator can use the Configure HA Node settings to specify the preferred role of each node in the pair, either primary or secondary. This can prevent unwanted failovers or configuration synchronization issues, such as the one described in the scenario. By setting the primary Citrix ADC to stay primary and the secondary Citrix ADC to stay secondary, the administrator can ensure that the existing configuration on the primary node is preserved and replicated to the secondary node, and that the roles of the nodes are not reversed. The stayprimary and staysecondary options can be enabled or disabled by using the -stayPrimary and -staySecondary parameters in the CLI or by checking or unchecking the Stay Primary and Stay Secondary check-boxes in the GUI.

Therefore, the correct answer is A. Set the primary Citrix ADC to stay primary in the Configure HA Node settings and B. Set the secondary Citrix ADC to stay secondary in the Configure HA Node settings.

Correct Answer: A. Operator

Short Explanation with reference: A command policy is a set of rules that regulates which commands, command groups, virtual servers, and other entities that users and user groups are permitted to use on a Citrix ADC appliance1. Citrix ADC provides a set of built-in command policies that have predefined permission levels for different types of users1. The built-in command policy permission levels are as follows1:

• Read-only: Users can view the configuration of the appliance, but cannot modify it. They can also view statistics and run show commands.
• Operator: Users can view and modify the configuration of the appliance, but cannot save the configuration or access the shell. They can also enable and disable services and servers, clear counters, and run show commands.
• Network: Users can view and modify the network configuration of the appliance, such as interfaces, routes, VLANs, and so on. They can also save the configuration and access the shell.
• Sysadmin: Users have full access to all commands and features of the appliance.

To create local, limited-privilege user accounts for other administrators who require only read-only access and the ability to enable and disable services and servers, the administrator can use the built-in command policy permission level of Operator (option A). This permission level allows users to perform these tasks, but not others that are not required or authorized1. The other options are incorrect because they either grant more privileges than necessary or do not allow enabling and disabling services and servers. Therefore, the correct answer is A. Operator.

Correct Answer: A. Citrix Application Delivery Management (ADM)

Short Explanation with reference: Citrix Application Delivery Management (ADM) is a web-based tool that provides end-to-end visibility and management for Citrix ADC deployments. It also enables administrators to view real-time and historical data on response time, client network latency, and server-side processing time for applications that are load balanced on the Citrix ADC1. HDX Insight, WAN Insight, and Security Insight are features of Citrix ADM that provide specific insights for HDX traffic, WAN optimization, and security events respectively1. They are not standalone tools that can be used to gather information on latency and response time. Therefore, the correct answer is A. Citrix Application Delivery Management (ADM).

Correct Answer: B. MIR DISABLED

Short Explanation with reference:

MIR (Multiple IP Response) is a feature that allows the Citrix ADC appliance to send the IP addresses of all the active services in the DNS response when a client requests the IP address of a GSLB (Global Server Load Balancing) virtual server. This can improve the performance and availability of the GSLB service, as the client can choose the best service based on its own criteria, such as round-trip time or proximity. However, MIR can also cause some issues, such as DNS caching, client-side load balancing, and security risks. Therefore, a Citrix Administrator can use the set gslb vServer -MIR DISABLED parameter to change this behavior and disable MIR for a specific GSLB virtual server. This will make the appliance send only one IP address in the DNS response, which is selected based on the configured load balancing method. Therefore, the correct answer is B. MIR DISABLED.

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.

Correct Answer: A. MAC-based forwarding (MBF)

Short Explanation with reference:

MAC-based forwarding (MBF) is a mode on a Citrix ADC that can be used to avoid asymmetrical packet flows and multiple route/ARP lookups. MBF enables the Citrix ADC to forward packets based on the MAC address of the destination server, instead of the IP address. This way, the Citrix ADC does not need to perform routing or ARP resolution for each packet, which reduces the processing overhead and improves performance. MBF also ensures that the return traffic from the server follows the same path as the incoming traffic from the client, which avoids asymmetrical routing issues.

MBF can be enabled on a Citrix ADC by using the GUI or the CLI of the appliance. MBF can be applied to a specific service or a service group, or to all services on the appliance. MBF can also be used in conjunction with other features, such as direct server return (DSR) and link load balancing (LLB).

Therefore, option A is the correct answer.

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.
