Citrix 1Y0-A21 Online Questions & Answers

• Question 1:

  Scenario: An administrator has set up four Web servers for load balancing. The administrator wants to monitor the response codes from the site to determine whether the site is up. The administrator has bound a custom HTTP monitor to the HTTP services. When the monitor is bound, the services go down so the administrator unbinds the monitor to bring the state of the services to UP. The administrator runs a HTTP header trace and finds that the site is responding with a redirect.

  Which two options can the administrator use to get the service state to UP? (Choose two.)

  A. Create a new HTTP monitor with a 200 response code and bind it to the service.
  B. Create a new HTTP monitor with a longer response timeout and bind it to the service.
  C. Modify the custom HTTP monitor with the same redirect response code the site is sending and bind it to the service.
  D. Modify the custom HTTP monitor with the HTTP request going to a page that responds with a 200 response code and bind it to the service.
  C. Modify the custom HTTP monitor with the same redirect response code the site is sending and bind it to the service.
  D. Modify the custom HTTP monitor with the HTTP request going to a page that responds with a 200 response code and bind it to the service.

• Question 5:

  Scenario: A company has contracts with multiple ISPs and would like to use all of them for Internet connections. The company also plans to use a NetScaler system for load balancing and failover. What can an administrator configure to ensure that all ISP connections are being used and return traffic maintains the same path as the inbound traffic in this environment?

  A. Round robin load balancing with INAT configured
  B. Link load balancing with RNAT and USNIP enabled
  C. Multiple VLANs with Ingress rules and USIP enabled
  D. A load balancing policy with the appropriate preferred IP and preferred port parameters configured

• Question 6:

  Scenario: An administrator is planning a software upgrade of a NetScaler HA pair from NetScaler version 8.1 Standard Edition to version 9.2 Enterprise Edition in order to take advantage of the new features. In the current environment, the NSIP for the pair is an IPv4 address.

  Which two steps must the administrator take to complete the NetScaler migration in this scenario? (Choose two.)

  A. Obtain a new NetScaler license.
  B. Enable the IPv6 protocol translation.
  C. Add the NSIP address after the HA pair has been upgraded.
  D. Ensure propagation and synchronization are disabled during migration.
  A. Obtain a new NetScaler license.
  D. Ensure propagation and synchronization are disabled during migration.

• Question 7:

  Scenario: A banking company plans to use their NetScaler system to improve their site performance. They will use NetScaler to direct traffic to different servers so that users accessing the mortgage page go to one set of servers, users accessing the banking page go to a second set of servers, users applying for a student loan go to a third set of servers and all other traffic goes to the home page. The administrator has already enabled the necessary features and bound the appropriate services to the load balancing virtual servers. In which order could the administrator perform the actions to define a content switching virtual server to meet these requirements?

  A. Add the content switching virtual server, add the default policy and add the other policies; then bind the load balancing virtual server and policy to the content switching virtual server; then bind the default load balancing virtual server to the content switching virtual server with the default policy.
  B. Add the content switching virtual server, bind the load balancing virtual server to the content switching virtual server, add a policy and bind the policy to the load balancing virtual server; then bind the default load balancing virtual server to the content switching virtual server without associating a policy.
  C. Add the policy, add the default policy, bind the policy to the load balancing virtual server, add the content switching virtual server, bind the load balancing virtual server to the content switching virtual server; then bind the default load balancing virtual server to the content switching virtual server with the default policy.
  D. Add the named expressions, create the appropriate content switching policy and add the content switching virtual server; bind the load balancing virtual server and policy to the content switching virtual server and then bind the default load balancing virtual server to the content switching virtual server without associating a policy.
  D. Add the named expressions, create the appropriate content switching policy and add the content switching virtual server; bind the load balancing virtual server and policy to the content switching virtual server and then bind the default load balancing virtual server to the content switching virtual server without associating a policy.

• Question 8:

  Scenario: An administrator has created and configured services on load balanced virtual servers. The administrator then enabled the compression feature on a NetScaler deployment using the Configuration Utility. After adding additional services, the administrator decides to check the Dashboard for the compression statistics. However, when looking over the statistics, the administrator notices an extremely low count in the policy hit counter.

  What could be causing the low count in the policy hit counter?

  A. The administrator did not bind the services to a virtual server.
  B. The administrator has not restarted the Dashboard after enabling the compression feature.
  C. The administrator has failed to manually enable compression for the services created prior to enabling the compression feature.
  D. The administrator failed to bind the HTTP services to an SSL load balancing virtual server, and failed to bind the SSL services to an HTTP load balancing virtual server.
  C. The administrator has failed to manually enable compression for the services created prior to enabling the compression feature.

• Question 10:
