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
Scenario: An administrator is configuring two NetScaler systems in an HA pair. The administrator configured LDAP Authentication to allow domain administrators to manage the NetScaler appliances and also created an authentication server profile and policy. Afterwards, the administrator plans to verify which groups are extracted upon login by the intended users during testing of the authentication server profile and policy.
Which of the following commands from the NetScaler shell will display the extracted groups?
A. tail -f /var/log/ns.log
B. cat /tmp/aaad.debug
C. nsconmsg -K /var/nslog/newnslog -d event
D. nsconmsg -k /var/nslog/newnslog -d consmsg
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
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.
Scenario: An administrator has set up four Web servers for load balancing. The administrator wants to monitor the response codes from the site to determine whether the site is up. The administrator has bound a custom HTTP monitor to the HTTP services. When the monitor is bound, the services go down so the administrator unbinds the monitor to bring the state of the services to UP. The administrator runs a HTTP header trace and finds that the site is responding with a redirect.
Which two options can the administrator use to get the service state to UP? (Choose two.)
A. Create a new HTTP monitor with a 200 response code and bind it to the service.
B. Create a new HTTP monitor with a longer response timeout and bind it to the service.
C. Modify the custom HTTP monitor with the same redirect response code the site is sending and bind it to the service.
D. Modify the custom HTTP monitor with the HTTP request going to a page that responds with a 200 response code and bind it to the service.
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
Scenario: An administrator has set up a NetScaler system with two interfaces connected to the DMZ network inside the organization's DMZ. The administrator configured the NSIP and MIP addresses and then created a virtual server on port 80 using HTTP in order to load balance the Web servers in the network environment. While reviewing the console messages, the customer sees several "channel muted" messages, high CPU utilization on the switch and receives complaints about slow response from the servers.
Which two options can the administrator use to fix this issue? (Choose two.)
A. Bind a VLAN to the interfaces with a SNIP.
B. Set up link aggregation on the two interfaces.
C. Remove one interface from the DMZ network.
D. Configure a second mapped IP on the NetScaler.
Which command can an administrator use to display the node state in an HA pair?
A. show ha pair
B. show ha state
C. show ha node
D. show ha primary
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.
