Scenario: A website that provides hotel bookings lists each hotel through their membership number on the site URL. For example, the Martello Tower member ID is 6754 and its web presence is at http:// www.hoteltestwebsite.com/hotels/6754/index.html.

There are 20,000 hotels in the database of the website. The website business owner no longer wants to display the hotel sites for hotel numbers 1-10000, inclusive. A NetScaler Engineer must configure an appropriate responder page to indicate that these sites are unavailable.

Which expression will meet the requirements of the business owner?

A. HTTP.REQ.URL.PATH.GET(2).TYPECAST_NUM_T(DECIMAL).BETWEEN(0, 10000)

B. HTTP.REQ.URL.AFTER_STR("hotels").TYPECAST_NUM_T(DECIMAL).BETWEEN(0, 10000)

C. HTTP.REQ.URL.BEFORE_STR("index.html").TYPECAST_NUM_T(DECIMAL).BETWEEN(0, 10000)

D. HTTP.REQ.URL.PATH.GET(1).TYPECAST_NUM_T(DECIMAL).GT(0) andand HTTP.REQ.URL.PATH.GET(1).TYPECAST_NUM_T(DECIMAL).LT(10000)

What are two benefits of using Link Aggregation Control Protocol (LACP)? (Choose two.)

A. Redundancy

B. Compression

C. Reduce TCP latency

D. Increased throughput

Which IP address type should be bound to a VLAN in order to isolate traffic to backend services?

A. Virtual IP (VIP)

B. Cluster IP (CLIP)

C. Subnet IP (SNIP)

D. NetScaler IP (NSIP)

Scenario: An engineer has configured an SSL virtual server and has bound a service group of type HTTP containing several servers. The service group is UP but the virtual server is in a DOWN state. The engineer has verified that the SSL feature is enabled.

What should the engineer do to ensure that the virtual server shows as UP?

A. Add a monitor that checks for HTTP.

B. Change the service group to type SSL.

C. Bind an SSL certificate to the virtual server.

D. Configure the service group to use port 443.

E. Change the monitor for a larger time out period.

A network engineer has noted that the primary node in an HA pair has been alternating as many as three times a day due to intermittent issues.

What should the engineer configure to ensure that HA failures are alerted?

A. LACP

B. SNMP

C. Route monitors

D. Failover Interface Set

Scenario: A network engineer monitoring an HTTP service-related issue needs to view only the relevant data pertaining to the service being monitored. The IP address of the back-end service being monitored is

10.10.1.99. The NSIP address is 10.10.1.230.

Which command should the engineer execute to monitor data relevant to this issue only in real time?

A. telnet

B. traceroute

C. nsconmsg

D. nstcpdump

Scenario: A network engineer has configured GSLB for a multisite environment. All GSLB services show as UP with an UP MEP status.

The engineer has observed that DNS queries are directed to the SNIP of the NetScaler; however, no DNS response is being received.

How can the engineer resolve this issue?

A. Add an ADNS service on the SNIP.

B. Change the DNS delegation to the NSIP.

C. Create a load balancing virtual server for DNS.

D. Select the "Send all "active" service IPs' in response (MIR)" option.

Scenario: Primary NetScaler (NS1) is licensed for 10000 Maximum ICA users and 305 Access Gateway users. Secondary NetScaler (NS2) is licensed for 10000 Maximum ICA users and five Access Gateway users. From where and which command should a network engineer run to display diagnostics on the

licenses?

A. From the shell, run 'view license'.

B. From the shell, run 'more /var/log/license.log'.

C. From the command-line interface, run 'show license'.

D. From the command-line interface, run 'cat /var/log/license.log'.

An engineer has configured a DNS virtual server on a NetScaler appliance but the monitors are showing DOWN and DNS resolution is failing.

Which of the following should the engineer check?

A. Port 53 between the VIP address and the DNS servers is allowed

B. That a ADNS_TCP service has been configured on the NetScaler

C. That the load balancing feature has been enabled on the NetScaler

D. Port 53 between the NSIP address and the DNS servers is allowed

E. Port 53 between the SNIP address and the DNS servers is allowed

Scenario: An engineer has a NetScaler system with NSIP 192.168.10.1 with subnet mask 255.255.0.0. The company changed the IP network to use subnet mask 255.255.255.0.

Which two commands could the engineer run to modify the subnet mask of the NSIP? (Choose two.)

A. ifconfig

B. configns

C. set ns ip

D. add ns ip

What are two ways in which the NetScaler TCP buffering feature improves application performance? (Choose two.)

A. Buffers the client request

B. Buffers the server response

C. Forwards the response to the client at the speed of the client network

D. Forwards the request to the server at the speed of the server network

Scenario: A network engineer adds a secondary node for high availability (HA) purposes. To confirm the implementation is working, the engineer initiates a fail over; however when this is complete, some virtual servers are un-reachable.

What is a possible cause of this issue?

A. SSL has not been enabled as a feature.

B. The network configuration is mismatched on the nodes.

C. HA sync does not propagate network settings by default.

D. The nsroot password has been changed on the new node.

Scenario: A NetScaler engineer needs to enable access to some web servers running on an IPv6 only network. The clients connecting the services are on an IPv4 network. The engineer has already enabled IPv6 on the NetScaler.

What does the engineer need to do in order to provide access to the services on the IPv6 network?

A. Create an IPv6 tunnel and a IPv4 virtual server.

B. Configure an IPv6 VLAN and bind the required interface.

C. Create a IPv4 virtual server and bind the service group to it.

D. Create an IPv6 ACL and a IPv4 virtual server and bind the ACL to the virtual server.

Scenario: For security reasons, the NSIP needs to be configured to only be accessible on interface 0/1,

which is VLAN 300.

The NSIP address is 10.110.4.254 and the subnet mask is 255.255.255.0.

How would the network engineer achieve this configuration?

A. set ns config -nsvlan 300 -ifnum 0/1

B. set ns ip 10.110.4.254 -gui ENABLED -vrID 300

C. add vlan 300 set ns ip 10.110.4.254 -mgmtAccess ENABLED

D. set ns config -IPAddress 10.110.4.254 -netmask 255.255.255.0
