To which three bind points can a Citrix Administrator bind a session policy, to enable Clientless access? (Choose three.)
Correct Answer: ADE
To enable Clientless access, a Citrix Administrator can bind a session policy to three specific bind points: Group, User, and Virtual server. These bind points ensure that the session policy is applied correctly to users either individually or as part of a group, and at the entry point where users connect to the network services.
Scenario: A Citrix Administrator is managing a NetScaler SDX running eight NetScaler instances. The administrator first needs to upgrade the firmware on the instances. However, the administrator is concerned that it needs to be done all at once.
What upgrading flexibility does SDX provide in this scenario?
Correct Answer: C
NetScaler SDX allows the instances to be upgraded on an individual basis, enabling different instances to run different firmware versions if required. This provides flexibility for the administrator to upgrade instances one at a time rather than all at once.
Scenario: A Citrix Administrator has configured a NetScaler active-passive high availability (HA) pair. When the HA pair fails over, customers are unable to access the hosted websites. After some troubleshooting, the administrator found that the upstream router was NOT updating its ARP table.
What can the administrator configure to resolve this issue?
Correct Answer: B
When configuring a NetScaler active-passive high availability (HA) pair, ensuring that the upstream router updates its ARP table after a failover is crucial. This can be addressed by configuring a Virtual MAC (VMAC). By using VMAC, the MAC address used by the primary node is shared by the secondary node upon failover. This prevents the need for the upstream router to learn a new MAC address and update its ARP table, thus ensuring a seamless transition and continuous accessibility of hosted websites.
A Citrix Administrator is configuring a NetScaler high availability (HA) pair and needs to ensure that one NetScaler is UP and primary at all times to ensure the business websites are always available.
What does the administrator need to do ensure that the NetScalers still handle web traffic in the event that both nodes become unavailable or fail a health check?
Correct Answer: B
To ensure that web traffic is handled even if both nodes become unavailable or fail a health check, the administrator needs to configure HA Fail-safe mode on each NetScaler independently. This setup allows each node to continue handling traffic through backup methods when partially available, guaranteeing that one node is always primary in critical situations.
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?
Correct Answer: C
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'.
