Scenario: A network administrator needs to configure VLANs on a NetScaler to support multiple networks. The NetScaler is connected through interface 1/1 to a switch port where VLAN10 is configured. This NetScaler is also connected through interface 1/2 to a switch port that is configured for VLAN20.
Given this scenario, which two steps does the administrator need to take to configure the NetScaler for VLAN10? (Choose two.)
A. add vlan 10
B. set vlan 10 -ifnum 1/1
C. bind vlan 10 -ifnum 1/2
D. bind vlan 10 -ifnum 1/1
E. bind vlan 10 -ifnum 1/1 -tagged
Scenario: An administrator is planning a software upgrade of a NetScaler HA pair from NetScaler version
8.1 Standard Edition to version 9.2 Enterprise Edition in order to take advantage of the new features. In the current environment, the NSIP for the pair is an IPv4 address.
Which two steps must the administrator take to complete the NetScaler migration in this scenario? (Choose two.)
A. Obtain a new NetScaler license.
B. Enable the IPv6 protocol translation.
C. Add the NSIP address after the HA pair has been upgraded.
D. Ensure propagation and synchronization are disabled during migration.
Scenario: An administrator has created and configured services on load balanced virtual servers. The administrator then enabled the compression feature on a NetScaler deployment using the Configuration Utility. After adding additional services, the administrator decides to check the Dashboard for the compression statistics. However, when looking over the statistics, the administrator notices an extremely low count in the policy hit counter.
What could be causing the low count in the policy hit counter?
A. The administrator did not bind the services to a virtual server.
B. The administrator has not restarted the Dashboard after enabling the compression feature.
C. The administrator has failed to manually enable compression for the services created prior to enabling the compression feature.
D. The administrator failed to bind the HTTP services to an SSL load balancing virtual server, and failed to bind the SSL services to an HTTP load balancing virtual server.
When planning a deployment, in which setup scenario must an administrator configure the NetScaler system as the default router for the servers in the environment?
A. When USNIP is configured
B. In a single subnet configuration
C. In a two-arm mode configuration
D. When USIP is configured for services

A. Stay primary
B. Stay secondary
C. Disable HA propagation
D. Disable HA synchronization
An administrator must first enable the __________ feature before a URL transformation policy can be used in a network environment. (Choose the correct option to complete the sentence.)
A. rewrite
B. responder
C. content filtering
D. URL transformation
An administrator wants to limit access to the NetScaler GUI and has configured ACLs to achieve this; however, everyone is still able to access the NetScaler administration tools.
What could be causing this issue?
A. Layer-3 mode is enabled.
B. TCP buffering is enabled.
C. The configured ACLs have not been applied/committed.
D. The ACLs have not been propagated to both NetScalers in the HA pair.
Scenario: An administrator plans to set up a NetScaler in HA mode. One of the requirements for the environment is to ensure that traffic is handled in the most reliable way even if both nodes in HA are unhealthy or partially fail.
Which setting must the administrator configure to ensure the traffic is handled in the most reliable way, even if both nodes in HA are unhealthy?
A. AutoFail
B. FailSafe
C. FailActive
D. Force Failover
An administrator set up a NetScaler pair in HA but later noticed that the configuration changes made on the primary node were NOT synchronized with the secondary node.
Which configuration setting must be corrected for successful configuration synchronization between both nodes in HA mode?
A. HA monitoring on interfaces is set to off.
B. HA monitoring on the node IDs is set to off.
C. nsroot password is not identical for both nodes.
D. RPC node password is not identical for both nodes.
Scenario: A network administrator working with two NetScaler systems has encountered an issue with HA. The administrator notices that HA synchronization is failing. The administrator has already run the
Which two additional steps should the administrator take to collect the appropriate data in order to troubleshoot this issue? (Choose two.)
A. Collect the files in /var/core.
B. Collect the files in /var/log/auth.log.
C. Run show techsupport from both NetScalers.
D. Run /netscaler/nstrace.sh -sz 0 to gather an nstrace.
