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

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: 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.
