A Citrix Administrator configured global server load balancing (GSLB) for www.citrix.com, with two ADNS services named Citrix ADC 1 and Citrix ADC 2 in the setup.
Which record does the administrator need to add on the parent DNS server to delegate requests from www.citrix.com to Citrix ADC 1 and Citrix ADC 2?

Scenario: A Citrix Administrator configured Citrix ADC load balancing to send requests to one of three identical backend servers. Each server handles multiple protocols, and load balancing is set up in round-robin mode.
The current load-balancing setup on the Citrix ADC is:
* One load-balancing vServer with one externally accessible VIP
* One service created for each protocol type
* One server entity for each backend resource
During business hours, the administrator wants to make changes to one backend server without affecting the other servers.
What is the most efficient way for the administrator to ensure that all traffic is routed away from the server without impeding responses from other resources?

Scenario: Client connections to certain vServers are abnormally high. A Citrix Administrator needs to be alerted whenever the connections pass a certain threshold.
How can the administrator use Citrix Application Delivery Management (ADM) to accomplish this?

Scenario: A Citrix Administrator suspects an attack on a load-balancing vServer (IP address 192.168.100.25).
The administrator needs to restrict access to this vServer for 10 minutes.
Which Access Control List (ACL) will accomplish this?
