Scenario: An administrator is managing a network environment with a stand-alone NetScaler system. The speed of the interfaces currently being used is inadequate for the amount of traffic that the NetScaler system is managing. The administrator needs to increase the available bandwidth on the system. The administrator also wants to add redundancy to the interfaces for failover.

What can the administrator do to meet the needs of this scenario with minimal change to the current network environment?

A. Configure multiplexing.

B. Configure link aggregation.

C. Create a load balancing policy for the interfaces.

D. Add a second NetScaler device and configure HA.

An administrator needs to add a new node to an existing NetScaler system to create an HA pair.

In order to prevent the new node from taking over as primary, the administrator should select the __________ setting on the new node. (Choose the correct option to complete the sentence.)

A. Stay primary

B. Stay secondary

C. Disable HA propagation

D. Disable HA synchronization

Which page is displayed to the user if a catch-all policy is NOT defined on a content switching virtual server configured on the NetScaler?

A. Users get an HTTP/1/.1 Error.

B. Users get an Access Denied Page.

C. The policy with the lowest priority gets evaluated.

D. Users are redirected to the page configured in the redirectURL parameter of the CSV server.

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 needs to satisfy the following conditions:

-The traffic should be encrypted end-to-end

-

There is no certificate configured on the virtual server

Which type of virtual server should the administrator configure on the NetScaler?

A.

SSL

B.

TCP

C.

HTTP

D.

SSL_TCP

E.

SSL_BRIDGE

An administrator needs to configure a health check for Web servers so that the probe fails if the monitor does NOT receive the expected data in the body of the response for an encrypted HTTP request.

How should the administrator configure the health check in the Configuration Utility to meet this requirement?

A. Add an HTTPS monitor and type in the appropriate HTTPs request and response.

B. Add an HTTP monitor, select the secure parameter and type in the appropriate HTTP response code.

C. Add an HTTP monitor, select the secure parameter and type in the appropriate HTTP request and response.

D. Add an HTTP-ECV monitor, select the secure parameter and type in the appropriate send and receive string.

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: An administrator finished installing a NetScaler appliance and configured a load balancing virtual server that has four services bound. The configured load balancing method for the virtual server is set to use least connection. The administrator later added a fifth server to the virtual server. However, when testing load balancing, the administrator finds that the virtual server is using round robin instead of least connection.

Why would the NetScaler system be using round robin as the load balancing method instead of least connection?

A. The administrator did not save the configuration correctly.

B. The NetScaler is using slow start mode for the virtual server.

C. Least connection will only function when more than five servers are load balanced.

D. Least connection is not a load balancing method that can be used for Web servers.

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 command on both nodes but needs more information.

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.

An administrator is determining when a particular service was unavailable in the past due to a failure condition detected by the assigned monitor.

Which NetScaler Configuration Utility option would report the service states detected in the past?

A. View events

B. Memory usage

C. View dmesg boot

D. TCP/IP Connections

E. View console messages
