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 andand !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.)
A. keep; request
B. keep; response
C. remove; request
D. remove; response

The logs are being filled with messages like the ones below:
Oct 6 14:03:23
Oct 6 14:03:30
Oct 6 14:03:30
Oct 6 14:03:30

A. Link redundancy is required.
B. Route monitors are required.
C. HA monitor is disabled in some interfaces.
D. The NetScaler appliances are configured on different networks.
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?
A. SureConnect
B. Compression
C. TCP Buffering
D. Surge Protection
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?
A. Redirected to http://www.external.hosting.com
B. Forwarded to the backup server, ignoring the query
C. Forwarded to the backup server, preserving the query
D. Redirected to http://www.external.hosting.com/path/query
Scenario: A NetScaler Engineer recently enabled the HTTP Compression feature. In reviewing the HTTP compression statistics, the engineer notices that content from all HTTP virtual servers created prior to enabling the compression feature is NOT being compressed.
What should the engineer do to allow compression for any pre-existing HTTP virtual servers?
A. Recreate the HTTP virtual servers.
B. Recreate any existing compression policies.
C. Enable compression on the associated bound services.
D. Ensure 'Allow Server side compression' is unchecked on the NetScaler.
Scenario: A Network Engineer needs to provide a solution for mobile users who use devices that do NOT support basic access authentication.
Which three steps should be included as part of the engineer's plan to implement this requirement using NetScaler? (Choose three.)
A. Configure an OCSP responder.
B. Create an authentication VServer.
C. Configure a Pre-Authentication policy.
D. Create an LDAP authentication policy and bind it to the authentication server.
E. Enable and configure the authentication option on a VServer to use 401-based authentication.
F. Enable and configure the Authentication option on a load balancing VServer to use form-based authentication.
