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?

What is the only input format supported by the NetScaler when using the NetScaler Certificate
Import wizard within the configuration utility?

Scenario: A NetScaler Engineer retrieves the following configuration from support and enters it into
the command-line interface:
add rewrite action remove_server_header delete_http_header Server
add rewrite policy RP_remove_srv_header “HTTP.REQ.IS_VALID

&& !CLIENT.IP.SRC.IN_SUBNET(172.16.0.0/16)” remove_server_header
bind lb vserver lb_vsrv -policyName RP_remove_srv_header -priority 100 –
gotoPriorityExpression END -type REQUEST
The immediate effect of this configuration is that it will ____ the server header in the ____ if the
request is coming from a network other than 172.16.0.0/16. (Choose the correct set of options to
complete the sentence.)

What is the default load-balancing method?

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?

Scenario: A NetScaler Engineer is troubleshooting an issue and using /var/log/ns.log to view the
errors. The logs are being filled with messages like the ones below:

Which option should the engineer modify to stop these types of messages from getting logged in
/var/log/ns.log?

When a content-switching virtual server is used and idle client connections must stay established
longer than the default NetScaler value, in which two locations could an engineer adjust the client
timeout setting? (Choose two.)

Scenario: A company is hosting an external, Internet-facing website that is load balanced by a
NetScaler. The backend servers are on a 1 Gbps network and clients connect over 3G connections.
The Server Administrator reviewed the performance metrics on the backend servers and noticed a
lot of overall network retirements and retransmissions. Which NetScaler feature would help improve
the network performance of the backend servers in this scenario?

When would it be necessary to configure Failover Interface Set (FIS) in an environment that has
two NetScaler appliances in high availability (HA) mode?

Scenario: A NetScaler Engineer has configured a virtual server as follows:
set lb vserver web_vserver -redirectURL http://www.external.hosting.com
-backupVServer maint_vserver
The virtual server web_vserver is marked as DOWN; maint_vserver is marked as UP. The following

request is sent to the web_vserver:
GET /path/query HTTP/1.1
What would happen to this request?
