• Question 81:

  Scenario: An administrator must plan the deployment of a NetScaler system for an environment that requires:

  -All traffic to pass through the NetScaler appliance(s)

  -

  Outbound connections to the Internet from a non-routable subnet

  -

  Two Web server farms to be load balanced by the fewest connections

  -All consumer web site traffic to be secured with SSL

  - All traffic to pass through a network firewall prior to passing through the NetScaler appliance(s)

  -Fault tolerance

  -

  Disabled traffic bridging on the NetScaler

  B. Configure Layer 2 mode.
  C. Configure RNAT functionality.
  D. Deploy the NetScaler system with HA.
  E. Enable Independent Network Configuration (INC).
  F. Deploy the NetScaler system in an inline configuration.
  C. Configure RNAT functionality.
  D. Deploy the NetScaler system with HA.
  F. Deploy the NetScaler system in an inline configuration.

• Question 82:

  A. pattern sets
  B. entity templates
  C. inline expressions
  D. named expressions
  D. named expressions

• Question 83:

  Scenario: An administrator has set up the configuration of an HA pair so that each NetScaler appliance has four connected interfaces. In addition, two pairs of interfaces for each appliance are configured in a link aggregation channel. Which two additional steps should the administrator take to set up HA? (Choose two.)

  A. Configure a route monitor on the NetScaler.
  B. Disable the interfaces that are not connected.
  C. Enable HA monitoring on the physical interfaces only.
  D. Enable HA monitoring on the link aggregation channel.
  B. Disable the interfaces that are not connected.
  D. Enable HA monitoring on the link aggregation channel.

• Question 84:

  Scenario: An administrator is working within a network environment as depicted in the attached exhibit. The NetScaler systems in this HA pair need to exchange heartbeat packets over L3 through routers R3 and R4.

  

  How can the administrator achieve this HA functionality?

  A. Enable the dynamic routing feature.
  B. Configure Route Health Injection (RHI).
  C. Bind a route monitor to each NetScaler device.
  D. Enable Independent Network Configuration (INC).
  D. Enable Independent Network Configuration (INC).

• Question 85:

  Scenario: An administrator is attempting to force synchronization between two nodes in an HA setup. Once the synchronization is complete, the administrator receives a message. In order to verify that the synchronization has been successful, the administrator should execute the __________ command. (Choose the correct option to complete the sentence.)

  A. show node
  B. show monitor
  C. show sync status
  D. show system status
  A. show node

• Question 86:

  Scenario: A specific logging application hosted on one Web server in a farm requires the client IP address in order to process information correctly in an environment where a NetScaler system is load balancing all the Web servers. This application is the only one that requires the client IP address to function properly.

  How must an administrator configure Client IP header insertion appropriately for this scenario?

  A. As a global feature
  B. As an advanced server option
  C. As an advanced service option
  D. As an advanced virtual server option
  C. As an advanced service option

• Question 87:

  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
  C. config ns

• Question 88:

  An administrator has configured several virtual servers in a network environment and needs to determine their bandwidth utilization. Which information from the Dashboard can the administrator leverage to determine the bandwidth utilization for the virtual servers?

  A. Requests vs. responses
  B. Request bytes vs. response bytes
  C. Current client connections vs. current server connections
  D. Current server connections vs. current client Est connections
  B. Request bytes vs. response bytes

• Question 89:

  Assuming a NetScaler system is deployed to improve site performance, which feature must first be enabled to allow for other acceleration benefits for secure traffic?

  A. Configure Cache redirection.
  B. Configure load balancing for the Web servers.
  C. Configure priority queuing on the NetScaler system.
  D. Configure the SSL offload feature on the NetScaler system.
  D. Configure the SSL offload feature on the NetScaler system.
