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. 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<name> -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.
