Scenario: A NetScaler engineer is adding a new SSL certificate to a NetScaler device. During the
process the engineer receives an error message:
“Certificate with key size greater than RSA512 or DSA512 bits not
supported.”
The same process has been followed previously on the same model of NetScaler successfully.
What is the likely cause of this error?

What should a network engineer configure to set high availability for a load balanced virtual server?

Scenario: An engineer is configuring services to allow load balancing of backend web servers on
the internal network. The engineer bound multiple monitors to the first service, but notices that the
service is reporting as DOWN. The monitor threshold default has NOT been changed. What could
be causing this issue?

Scenario: The network engineer has created a monitor and bound it to a service group containing
four web servers to verify that the web application responds. During routine maintenance one of
the web servers is shut down; however, the server state remains UP and user requests are still
attempting to communicate with the server. What could be causing this problem?

Scenario: A network engineer has configured a load balancing virtual server for an HTTP
application. Due to the application architecture, it is imperative that a user’s session remains on a
single server during the session. The session has an idle timeout of 60 minutes. Some devices are
getting inconsistent application access while most are working fine. The problematic devices all
have tighter security controls in place. Which step should the engineer take to resolve this issue?

A company has two sites that host six cache web servers that are used to promote sales information.
Which feature on the NetScaler should an engineer enable to provide faster application
performance and also provide additional capacity if the demand increases for one site?

A network engineer needs to configure load balancing for secured web traffic that does NOT
terminate at the NetScaler device. Which type of session persistence method can the engineer
select for this scenario?

Scenario: A call center has deployed Access Gateway Enterprise to provide its employees with
access to work resources from home. Due to the number of available licenses, only selected
employees should access the environment remotely based on their user account information. How
could the engineer configure access to meet the needs of this scenario?

Scenario: A network engineer needs to re-configure the NetScaler to utilize two new VLANs –
VLAN2 and VLAN3. VLAN2 is an untagged VLAN and VLAN3 will require a .1q compliant tag.
Interface 1/1 is the only interface that will be used on the NetScaler. How could the engineer
configure the NetScaler so that it can communicate with both networks?

Scenario: A NetScaler appliance currently has a manually configured channel containing four
interfaces; however, the engineer has been told that the NetScaler must now only use a single
interface for this network. The engineer removes the channel and immediately notices a decrease
in network performance. How could the engineer resolve this issue?
