A Citrix Administrator needs to generate AppFlow data for internal ICA connections.
Which two connection methods could the administrator use to route internal ICA connections through NetScaler without modifying the existing network routing? (Choose two.)
Question No : 3
Scenario: A Citrix Administrator notices user sessions are disconnecting and reconnecting more often this week than last week, signaling a problem.
The administrator troubleshoots this issue and prepares to resolve it using persistence. However, the following considerations apply in the environment.
• It is a multi-proxy environment behind the NetScaler.
• USIP mode is enabled and applied to the services.
• The session timeout is very short.
• All users connect from the same location.
The administrator can use persistence based on the __________setting to resolve this issue. (Choose the correct option to complete the sentence.)
Question No : 4
Scenario: A Citrix Administrator suspects an attack on a load-balancing virtual server. The administrator needs to restrict access to the load-balancing virtual server (192.168.100.25) for 10 minutes.
Which Access Control List (ACL) will help to accomplish this requirement?
Question No : 5
A Citrix Administrator is configuring a NetScaler high availability (HA) pair and needs to ensure that one NetScaler is UP and primary at all times to ensure the business websites are always available.
What does the administrator need to do to ensure that the NetScalers still handle web traffic in the event that both nodes become unavailable or fail a hearth check?
Question No : 6
Scenario: A Citrix Administrator has configured a NetScaler active-passive high availability (HA) pair. When the HA pair fails over, customers are unable to access the hosted websites. After some troubleshooting, the administrator found that the upstream router was NOT updating its ARP table.
What can the administrator configure to resolve this issue?
Question No : 7
Scenario: A Citrix Administrator is managing a NetScaler SDX running eight NetScaler instances. The administrator first needs to upgrade the firmware on the instances. However, the administrator is concerned that it needs to be done all at once.
What upgrading flexibility does SDX provide in this scenario?
Question No : 8
Scenario: A NetScaler appliance is having intermittent issues. A Citrix Administrator is unable to identify the root cause and fix them. The administrator opened a Support ticket and the engineer assigned to the case requested all the logs and configuration information from the NetScaler.
Which technical support tool can the administrator use to gather all the information on the NetScaler to send to the Support Engineer?
Question No : 9
A Citrix Administrator would like to define granular policies to configure and enforce user environment attributes for XenApp and XenDesktop on NetScaler Gateway.
Which type of policy would enable this requirement?
Question No : 10
To which three bind points can a Citrix Administrator bind a session policy, to enable Clientless access? (Choose three.)
Question No : 11
Scenario: A Citrix Administrator has a NetScaler SDX appliance with several instances configured. The administrator needs one instance with two interfaces connected to forward packets that are NOT destined for its MAC address. Hence, the administrator has enabled Layer 2 mode. After enabling Layer 2 mode, the administrator found the interface status going up and down.
What can the administrator perform to resolve this issue?
Question No : 12
A Citrix Administrator needs to ensure that a revoked certificate is NOT being used for client certificate authentication.
Which two entities can the administrator select on the NetScaler? (Choose two.)
Question No : 13
A Citrix Administrator receives user complaints about latency while accessing an application that is being load-balanced on the NetScaler.
Which tool can the administrator use to gather information regarding Response time, Client network latency and Server-side processing time?
Question No : 14
Scenario: Client connections to certain virtual servers are abnormally high A Citrix Administrator needs to be alerted whenever the connections pass a certain threshold.
How can the administrator use NetScaler Management and Analytics System (MAS) to accomplish this requirement?
Question No : 15
Scenario: A NetScaler is configured with the following modes:
*Layer 3 mode
A Citrix Administrator configured a new router and now requires some of the incoming and outgoing traffic to take different paths through the new router However, the administrator notices that this is failing and takes a network trace. After a short monitoring period, the administrator notices that the packets are still NOT getting to the new router from the NetScaler.
Which mode should the administrator disable on the NetScaler to facilitate the addition of the new router and successfully route the packets?
