9: Scenario: A company is deploying a NetScaler system in a network environment in which there
is one non-routable subnet and some subnets are open to the public Internet. The administrator
plans to enable Use-Subnet-IP mode and disable Use-Source-IP mode.

(Choose two.)
A.VIP
B.MIP
C.SNIP

10: 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
Correct Answers: A

11: 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.
What must the administrator ensure is configured on the NetScaler system for this environment?
A.Static Routes
B.Link Load Balancing
C.Route Health Injection
D.Front-end Health Check
Correct Answers: C

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
Correct Answers: C

13: 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?
