Scenario: A NetScaler Engineer is configuring LACP (Link Aggregation Configuration
Protocol) on the NetScaler. The engineer adds interface 10/3 and 10/4 to LA/1 (which already contains interfaces 10/1 and 10/2) and is configured for VLAN 500.
VLAN 100 is bound to interface 10/3 and VLAN 200 is bound to interface 10/4.
VLAN 500 is bound to channel LA/1.
Which VLAN is shown with a "show interface" command for interface 10/3?

  • A. 1
  • B. 100
  • C. 200
  • D. 500

Answer : D

Which two of the following settings could be configured using a TCP profile that is bound to a service? (Choose two.)

  • A. TCP buffer size
  • B. Window scaling
  • C. TCP Server time-out values
  • D. Source IP for specific subnet
  • E. Allowed bandwidth throughput
  • F. Number of max concurrent TCP connections

Answer : A,B

Scenario: A NetScaler Engineer is addressing an issue discovered during a vulnerability scan. The security team is requiring that the engineer disable specific SSL ciphers on the
SSL VServer.
Which two methods could the engineer use to meet this requirement? (Choose two.)

  • A. Modify the list of ciphers in the Default cipher group.
  • B. Change the list of bound ciphers on the VServer directly.
  • C. Enable Cipher Redirect on the VServer and configure OCSP.
  • D. Disable SSLv2 Redirect on the VServer and update the CRLs.
  • E. Un-assign the default group, create a custom cipher group and assign it to the VServer.

Answer : B,E

Scenario: A NetScaler Engineer has received complaints from some users stating that their business applications are running slow. The engineer analyzes the application servers and sees the following CPU utilization:

ServerA is utilizing 20% CPU -

ServerB is utilizing 20% CPU -

ServerC is utilizing 100% CPU -
The engineer had set the load-balancing method to round robin but decided to change the load-balancing configuration for the business applications.
Which load-balancing method could the engineer use to address this issue?

  • A. Custom Load
  • B. Least Packets
  • C. Least Connections
  • D. Least Response time

Answer : A

Scenario: When the NetScaler was set up, compression was enabled. The network engineer would like to disable compression ONLY for a particular virtual server.
How could the engineer accomplish this?

  • A. Uncheck Compression in the system basic features.
  • B. Create a policy with a NOCOMPRESS action, bound to the global request point.
  • C. Disable compression on the services or service groups bound to the virtual server.
  • D. Create a policy with a NOCOMPRESS action, bound the virtual server Compression (request) point.

Answer : C

Which setting must an engineer ensure is configured before a Subnet IP (SNIP) could be used to communicate with servers on the same network segment?

  • A. Static route is defined
  • B. USIP mode is enabled
  • C. USNIP mode is enabled
  • D. Default gateway is defined

Answer : C

Scenario: A NetScaler Engineer must implement load-balancing on a web server farm that serves video clips to end users. Video clip files vary in size. The engineer needs to send traffic to the server with the least amount of network utilization.
Which load-balancing method should the engineer use?

  • A. Least Request
  • B. Least Bandwidth
  • C. Least Connection
  • D. Least Response Time

Answer : B

As a result of connecting two NetScaler interfaces in the same L2 broadcast domain/VLAN
(unless link aggregation is configured), the NetScaler will __________. (Choose the correct option to complete the sentence.)

  • A. restart
  • B. disable one interface
  • C. cause a network loop
  • D. disable both interfaces

Answer : C

Which built-in TCP profile should a NetScaler Engineer choose to optimize backend server connections, where the servers reside on the same LAN as the appliance?

  • A. nstcp_default_tcp_lfp
  • B. nstcp_default_tcp_lnp
  • C. nstcp_default_tcp_lan
  • D. nstcp_default_profile

Answer : C

Scenario: A NetScaler Engineer has configured COOKIEINSERT persistence with a timeout value of two minutes on an SSL LBvServer. The idle time requirement for the application itself CANNOT be determined. Users report connections are intermittent. Once a session is disconnected, a user must re-authenticate in order to regain access.
In order to correct this issue, the engineer should set persistence to __________ with a timeout of __________ minutes. (Choose the correct set of options to complete the sentence.)

  • A. SOURCEIP; two
  • B. SSLSESSION; ten

Answer : D

A NetScaler Engineer would like to direct identical requests for the same service to specific cache servers.
Which load-balancing method should the engineer use?

  • A. URL Hash
  • B. Domain Hash
  • C. Source IP Hash
  • D. Source IP Destination IP Hash

Answer : A

An end user is receiving authentication errors when accessing a load-balancing virtual server that uses Authentication, Authorization and Access (AAA)-TM.
Which shell command should a NetScaler Engineer execute to show AAA events in real time to help diagnose this issue?

  • A. tail /tmp/aaad.debug
  • B. cat /tmp/aaad.debug
  • C. grep aaa /tmp/nskrb.debug
  • D. egrep aaa /tmp/pitboss.debug

Answer : B

Scenario: A network engineer is going to roll out an upgrade from a 9.x version on a standalone NetScaler appliance using the command-line interface.
Which two items does the engineer need to download before proceeding with the upgrade?
(Choose two.)

  • A. SSL Certificates Files
  • B. NetScaler Firmware File
  • C. NetScaler Configuration file
  • D. NetScaler Documentation File

Answer : B,D

Scenario: A NetScaler Engineer is troubleshooting a high-availability issue. The engineer needs to determine if the port being used by the high-availability heartbeats is blocked.
Which port is used by high-availability heartbeats?

  • A. 3003
  • B. 3008
  • C. 3010
  • D. 3011

Answer : A
