A. Round robin load balancing with INAT configured

B. Link load balancing with RNAT and USNIP enabled

C. Multiple VLANs with Ingress rules and USIP enabled

D. A load balancing policy with the appropriate preferred IP and preferred port parameters configured

An organization has a NetScaler HA pair that needs to be upgraded to the most recent build available for NetScaler version 9.2.

A. Disable propagation for the HA pair.

B. Disable synchronization for the HA pair.

C. Migrate the configuration to version 9.2.

D. Disable heartbeat communication (HAMON).

E. Enable Independent Network Configuration (INC).

F. Upgrade the Secondary NetScaler unit in the HA pair first.

An administrator is upgrading the NetScaler HA pair to the latest 9.2 version of NetScaler using the CLI. Which step should the administrator take to update the documentation library prior to the upgrade?

A. The documentation library is included as part of the build file.

B. Decompress the documentation bundle and run the included installer.

C. Place a copy of the documentation bundle in the same directory that contains the new build file.

D. Place the documentation bundle in the nsconfig directory where it will be executed automatically at boot.

An administrator needs to configure a NetScaler system in a manner that will increase the capacity and availability of a single communication channel between the NetScaler and another connected device. What should the administrator configure on the NetScaler system to achieve this requirement?

A. NIC teaming

B. Link Bonding

C. Link Aggregation

D. Interface Trunk mode

What must an administrator configure when adding a new SNMP manager to a NetScaler configuration using the Configuration Utility?

A. Source port

B. SNMP community string

C. Source Interface Number

D. SNMP manager IP address

E. SNMP Trap Type (Basic or Advanced)

Scenario: An administrator would like to set an organization's homepage search engine type to display differently based on a user's browser. If a user accesses the homepage from an Internet Explorer browser, then the Bing search engine should be displayed. If a user accesses the homepage using a Google Chrome browser, then the Google search engine should be displayed.

Which feature could an administrator use to meet the needs of the scenario?

A. Responder

B. Rate limiting

C. Priority Queuing

D. Content Filtering

Scenario: A banking company plans to use their NetScaler system to improve their site performance. They will use NetScaler to direct traffic to different servers so that users accessing the mortgage page go to one set of servers, users accessing the banking page go to a second set of servers, users applying for a student loan go to a third set of servers and all other traffic goes to the home page. The administrator has already enabled the necessary features and bound the appropriate services to the load balancing virtual servers. In which order could the administrator perform the actions to define a content switching virtual server to meet these requirements?

A. Add the content switching virtual server, add the default policy and add the other policies; then bind the load balancing virtual server and policy to the content switching virtual server; then bind the default load balancing virtual server to the content switching virtual server with the default policy.

B. Add the content switching virtual server, bind the load balancing virtual server to the content switching virtual server, add a policy and bind the policy to the load balancing virtual server; then bind the default load balancing virtual server to the content switching virtual server without associating a policy.

C. Add the policy, add the default policy, bind the policy to the load balancing virtual server, add the content switching virtual server, bind the load balancing virtual server to the content switching virtual server; then bind the default load balancing virtual server to the content switching virtual server with the default policy.

D. Add the named expressions, create the appropriate content switching policy and add the content switching virtual server; bind the load balancing virtual server and policy to the content switching virtual server and then bind the default load balancing virtual server to the content switching virtual server without associating a policy.

Scenario: An administrator is configuring content switching to switch between static and dynamic requests. The administrator has completed the following:

-Content switching feature is enabled

-Two CS policies have been created to identify static and dynamic requests

Which subsequent action should the administrator take after the above actions have been completed?

A. Create a load balancing virtual server for static requests and a separate load balancing virtual server for dynamic requests.

B. Create a virtual server for all requests but create a service for static requests and a separate service for dynamic requests.

C. Prioritize the content switching policies so that the policy associated with dynamic requests is higher than the policy associated to static requests.

D. Prioritize the content switching policies so that the policy associated with static requests is higher than the policy associated to dynamic requests.

Scenario: An administrator wants to change the NSIP in the current NetScaler deployment. However, when the administrator tries to change the IP in the GUI, the IP is shown as grayed out and cannot be changed. The administrator then tries to add a new NSIP but finds that there is no option in the GUI to add a new NSIP.

Which command can the administrator run from the command line to change the NSIP on the NetScaler?

A. set nsip

B. add nsip

C. config ns

D. ns config

Scenario: An administrator is configuring two NetScaler systems in an HA pair. The administrator configured LDAP Authentication to allow domain administrators to manage the NetScaler appliances and also created an authentication server profile and policy. Afterwards, the administrator plans to verify which groups are extracted upon login by the intended users during testing of the authentication server profile and policy.

Which of the following commands from the NetScaler shell will display the extracted groups?

A. tail -f /var/log/ns.log

B. cat /tmp/aaad.debug

C. nsconmsg -K /var/nslog/newnslog -d event

D. nsconmsg -k /var/nslog/newnslog -d consmsg
