Question 1
Scenario: A Citrix Administrator is troubleshooting a NetScaler issue. The administrator goes to the command line and from the Shell, tails the ns.log to view the log in real time to find the issue.

  1. The ns.log needs to be downloaded to the client machine for full viewing.
  2. The ns.log service has stopped and needs to be restarted.
  3. The ns.log is still running. Press ‘Enter’ and the ns.log will resume.

  3. Direct Server Return (DSR)
  4. SmartAccess

Which expressions can the administrator use to match the required traffic?
  1. CLIENT.IP.SRC.IN_SUBNET(10.107.149.0/24) && client.UDP.DSTPORT.EQ(53) || client.TCP.DSTPORT.EQ(53)
  2. CLIENT.IP.SRC.IN_SUBNET(10.107.149.0/24) && (client.UDP.DSTPORT.EQ(53) || client.TCP.DSTPORT.EQ(53))
  3. CLIENT.IP.SRC(10.107.149.0) && (client.UDP.DSTPORT.EQ(53) || client.TCP.DSTPORT.EQ(53))
  4. CLIENT.IP.SRC(10.107.149.0) && client.UDP.DSTPORT.EQ(53) || client.TCP.DSTPORT.EQ(53)
Correct answer: B

www.company.com 
www.company.net 
www.company.org 
The administrator would like to consolidate the website into a single, load-balanced SSL virtual server. 
Which action can the administrator take to use a single SSL virtual server?
  1. Bind the certificate of each website to a single SSL virtual server.
  2. Bind a multiple Subject Alternative Name (SAN) certificate to a single SSL virtual server.
  3. Bind a Wildcard certificate to a single SSL virtual server.
  4. Bind a Wildcard certificate to a Content Switching virtual server.
Correct answer: D
Question 7
In the Global Server Load Balancing (GSLB) configuration when dynamic proximity is implemented, the round trip time (RTT) between the _____________ and _____________ is measured to make the load decision. (Choose the correct option to complete the sentence.)
  1. IP address of the client; each of the GSLB sites.
  2. Local DNS of the client; each of the GSLB sites.
  3. Local DNS of the client; each of the GSLB services.
  4. IP address of the client; each of the GSLB services.

Question 8
Scenario: A Load Balancing virtual server (lb_vsrv_www) is configured to load balance service_1 and service_2. A Citrix Administrator needs to bind a content filter policy to the virtual server, such that if the user tries to access http://xenapp.citrix.com, then the request should go to service_1.
Which policy can the administrator use in this scenario?
  1. add filter action Redirect_Service_1_Act redirect Service_1 
    add filter policy Redirect_Service_1_Pol -rule “REQ.HTTP.HEADER HOSTANME CONTAINS xenapp.citrix.com” reqAction Redirect_Service_1_Act
  2. add filter action Redirect_Service_1_Act forward Service_1 
    add filter policy Redirect_Service_1_Pol -rule “REQ.HTTP.HEADER HOSTANME CONTAINS xenapp.citrix.com” reqAction Redirect_Service_1_Act
