QUESTION 32

Scenario: An engineer has configured a virtual server that users access using HTTP port

80. The web application also uses TCP port 81 and 8080 for non-user access. The engineer would like to prevent users from connecting to web servers if any of the ports go down.

A.

Increase the monitor threshold.

B.

Lower the server timeout value.

C.

Create additional virtual servers for ports 81 and 8080.

D.

Create monitors for ports 81 and 8080, and bind to the service or service group.

 

Answer: B

 

 

QUESTION 33

Scenario: An engineer executes the following commands:

 

add vlan 2

 

bind vlan 2 -ifnum 1/2

 

add ns ip 10.110.4.200 255.255.255.0

 

bind vlan 2 -IPAddress 10.110.4.200 255.255.255.0

QUESTION 34

Scenario: A network engineer has created an SSL offload virtual server. The virtual server shows as a DOWN state.

 

Which two scenarios could cause the virtual server showing as DOWN? (Choose two.)

 

A.

Persistence is set to NONE.

B.

The protocol should be SSL_TCP.

C.

A responder policy has been bound.

D.

The service is not bound to the virtual server.

E.

No SSL certificate is bound to the virtual server.

 

Answer: DE

 

 

QUESTION 35

Company policy states that SNMP management should only be allowed from specific hosts.

 

What should the network engineer do to prevent unauthorized access to SNMP?

 

A.

Add an SNMP manager.

B.

Add an SNMP trap destination.

C.

Check secure access only on the NSIP.

D.

Add an SNMP community name that is difficult to guess.

QUESTION 36

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?

 

A.

Change the NSVLAN to 3

Add VLAN 2 and bind interface 1/1 as untagged

B.

Enable the Tag all VLANs option on interface 1/1.

C.

Add VLAN2 and bind interface 1/1 as untagged

Add VLAN3 and bind interface 1/1 as tagged

D.

Add a SNIP for each VLAN

Enable management access on the SNIP for VLAN3

 

Answer: C

 

 

QUESTION 37

Scenario: Example.com runs a dating service site that provides a service with videos of candidates. They want to use RTSP load balancing to stream the videos more effectively.

 

Which load balancing method should the engineer select?

 

A.

Least packet

B.

Round Robin

C.

Least bandwidth

D.

Least connection

 

Answer: C

 

 

QUESTION 38

Scenario: An application that uses HTTP for connections and other protocols for different types of content has been deployed. Load balancing virtual servers have been created for each protocol and the engineer now needs to ensure that once a load balancing decision has occurred, further requests for different content are served from the same server.

 

 

 

Citrix 1Y0-351 : Practice Test

How could the engineer achieve this?

 

A.

Create a persistency group.

B.

Set the Spillover method to DYNAMICCONNECTION.

C.

Add a new virtual server for each protocol that is not directly addressable.

D.

Set each virtual server to use Source IP Hash as the load balancing method.

 

Answer: A

Explanation:Summary

A Web application may use HTTP and HTTPS in the same session. This article describes the configuration necessary to ensure persistence is maintained across both HTTP and HTTPS connections.

Background

The NetScaler allows us to configure persistency groups to accommodate exactly such a need. A practical example of this might be a shopping cart where items are browsed over HTTP, but purchased over HTTPS. If persistency were not maintained, it’s possible the shopping cart might be lost, the user logged out, or other adverse actions. By using persistency groups, the HTTP and HTTPS vServers are grouped together into one persistent entity.

Procedure

From the GUI:

1. Click and expand the Load Balancing node.

2. Click Persistency Groups.

3. Click Add.

4. Populate the Group Name field.

5. Choose between COOKIEINSERT, SOURCEIP or RULE from the Persistence dropdown and configure a timeout.

6. Choose a backup persistence method if desired.

7. Select the vServers to be grouped from the Available Virtual Servers list.

8. Click Add to move the vServers from the available list to the configured list.

From the command line interface (CLI):

Issue the following commands:

1. bind lb group <name of group> <vserver 1>

2. bind lb group <name of group> <vserver 2>

3. ….

4. set lb group <name of group> -persistenceType <persistence method> – persistenceBackup <backup persistence method>

QUESTION 39

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?

 

A.

Reset the unused interfaces

B.

Disable the unused interfaces

C.

Enable flow control on all interfaces

D.

Disable HA monitoring on the three interfaces that are no longer required

 

Answer: B

 

 

QUESTION 40

How could a network engineer gather detailed network information?

 

A.

System node -> Diagnostics -> Call home

B.

System node -> Diagnostics -> Start new trace

C.

System node -> Diagnostics -> Show techsupport

D.

System node -> Diagnostics -> Show running vs saved config

 

Answer: B
