• Question 82:

  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

  Correct Answer: C

• Question 83:

  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.

  Correct Answer: B

• Question 84:

  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.

  Correct Answer: AD

• Question 85:

  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.

  Correct Answer: C

• Question 86:

  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

  Which three steps must the administrator take to deploy the NetScaler system correctly for this environment according to best practices? (Choose three.)

  A. Configure proxy mode.

  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.

  Correct Answer: CDF

• Question 87:

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

  According to best practices, which three steps should the NetScaler administrator take to minimize downtime while accomplishing this task? (Choose three.)

  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.

  Correct Answer: ABF

• Question 88:

  Scenario: An ISP provides SaaS to enterprise customers as part of a cloud offering. A NetScaler is configured to support multi-tenant deployments. Traffic isolation for each enterprise (tenant) is achieved using VLAN segmentation for each enterprise customer. As an example, incoming client requests from enterprise customers are assigned to separate VLANs. Which feature can an administrator configure to specify that the VIP for customer1 will only listen to requests coming from VLAN1 and the VIP from customer2 will only listen for requests from VLAN2?

  A. Static Routes

  B. Policy-based routing

  C. MAC-based Forwarding

  D. Network-aware policies

  Correct Answer: D

• Question 89:

  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).

  Correct Answer: D

• Question 90:

  An administrator needs to configure a NetScaler system to dynamically advertise virtual IP addresses, directly connected routes and static routes to the upstream routers.

  What must the administrator ensure is configured on the NetScaler system for this environment?

  A. RNAT

  B. L3 mode

  C. Static Routes

  D. Health Check monitor

  E. Route Health Injection (RHI)

  Correct Answer: E
