Scenario: A Citrix Administrator suspects an attack on a load-balancing virtual server. The administrator needs to restrict access to the load-balancing virtual server (192.168.100.25) for 10 minutes.
Which Access Control List (ACL) will help to accomplish this requirement?
The correct ACL to use in this scenario needs to restrict access based on the destination IP address of the load-balancing virtual server (192.168.100.25). The TTL (Time to Live) value is also specified in seconds and must be set to 600 seconds (10 minutes). The correct format for creating this ACL in Citrix syntax requires the use of 'ns acl' since it supports destination IP filtering, unlike 'simpleacl'. Therefore, the correct command is: 'add ns acl rule1 DENY –destIP 192.168.100.25- TTL 600'.
correct answer is C https://docs.citrix.com/en-us/citrix-adc/current-release/networking/access-control-lists-acls/extended-acls-and-extended-acl6s.html
I think its B https://developer-docs.citrix.com/projects/netscaler-command-reference/en/12.0/ns/ns-simpleacl/ns-simpleacl/
B is wrong. SimpleACL can only do it for the Source IP, not the destination. correct answer is C https://docs.citrix.com/en-us/citrix-adc/current-release/networking/access-control-lists-acls/extended-acls-and-extended-acl6s.html
