  A. syslog
  B. nswlog
  C. newnslog
  D. nsconmsg
  Answer: C

  3. Where in the configuration utility can an administrator configure a NetScaler high availability pair to ensure that specific interfaces are NOT monitored?

  A. Use the appropriate default compression policy
  B. Configure the compression policy for HTTP requests only
  C. Remove the "Accept-Encoding" header from the HTTP responses
  D. Use Re-write to remove "Accept-Encoding" header from the HTTP requests
  Answer: D

  5. Scenario: An administrator needs to create a health check that will mark an HTTP service down if the bound monitor probe fails. The administrator wants to create a monitor and configure the health check so that a trap is sent if the monitor probe reply exceeds 20 milliseconds.
  How can the administrator create the monitor for this health check using the command line interface?
  A. set mon monitor-HTTP-1 HTTP -interval 20 milli
  B. add lb mon monitor-HTTP-1 HTTP -interval 20 milli

  Answer: D

  6. Scenario: An administrator must set up a NetScaler system network with USIP mode enabled. The NetScaler must be able to preserve client IP addresses in TCP/IP packets reaching the back-end servers except for connections coming from particular IP addresses that are defined in an ACL. In the case of connections coming from the IP addresses defined in the ACL, the packets reaching the back-end servers should receive the NetScaler IP address instead of the client IP address. On which entity should RNAT be configured to meet the requirements in this scenario according to best practices?
  A. ACL
  B. Client
  C. Virtual server
  D. Back-end server
  Answer: A

  7. Scenario: A network administrator is deploying a NetScaler system in an environment with a single subnet using this IP information:
  subnet: 192.168.10.32 netmask: 255.255.255.224 default gateway: 192.168.10.40 The administrator already set up the NSIP and MIP addresses using the command line interface.
  Which command could the administrator use to complete this set up successfully?
  A. add route 0.0.0.0 0.0.0.0 192.168.10.32
  B. add route 0.0.0.0 0.0.0.0 192.168.10.40
  C. add route 0.0.0.0 0.0.0.0 192.168.10.62
  D. add route 192.168.10.0 255.255.255.224 192.168.10.32
  E. add route 192.168.10.0 255.255.255.224 192.168.10.62
  Answer: B

  8. Scenario: An administrator is configuring a NetScaler system in one-armed mode. The NetScaler appliances are connected to the network through a switch and will be configured as a pair with high availability (HA) enabled.
  Which two steps should the administrator take to succesfully configure HA in this environment? (Choose two.)
  A. Ensure the NSIP is identical on both systems
  B. Configure a unique nsroot password on each node of the HA pair
  C. Disable all system interfaces except the one connected to the switch
  D. Configure a Remote Procedural Call (RPC) node password on each node of the HA pair
  Answer: CD

  9. Which event would trigger a failover in a high availability pair?
  A. The primary appliance reboots.
  B. A forced synchronization event fails.
  C. A monitored interface fails on the secondary node.
  D. The default gateway does not return a heartbeat packet from the primary node.
  Answer: A

  10. An administrator configured cache redirection and needs to provide a report of how that feature is functioning in the network environment.
  What can the administrator use to see a graphical representation of the statistics for the vserver performing the cache redirection?
  A. The monitor view for the service bound to the correct vserver
  B. The chart option in the Dashboard once the correct vserver is selected
  C. The chart option in the Dashboard for the service bound to the correct vserver
  D. The request and response rates option in the Dashboard once te correct vserver is selected
  Answer: B

  11. Which SNMP trap must an administrator configure to be informed when the response time for a monitor probe that had exceeded the set threshold returns to normal?
  A. entityup
  B. entitydown
  C. monRespTimeoutAboveThresh
  D. monRespTimeoutBelowThresh
  Answer: D

  12. Scenario: An administrator installed a NetScaler system and configured the NSIP and MIP for the system. The NetScaler system will be used primarily for load balancing in this environment.
  Which additional step must the administrator take to ensure that the NetScaler system can perform the necessary server load balancing in this environment?
  A. Disable USIP mode on both nodes
  B. Use the MIP as the NSIP for a high availability environment
  C. Create VIPs for the front-end connections to the back-end servers
  D. Enable USNIP mode for the front-end connections to the back-end servers
  Answer: C

  13. Scenario: An administrator is planning the necessary configurations on a NetScaler system for an environment that requires the NetScaler system to advertise virtual IP addresses, directly connected routes and static routes on the upstream routers.

  A. Static Routes
  B. Link Load Balancing
  C. Route Health Injection

  C. SNMP group
  D. SNMP community
  Answer: D

  16. Scenario: An administrator is configuring the NetScaler-owned IP address for a network environment where the NetScaler IP, the mapped IP, and the back-end servers will be located on separate subnets.
