Question 25

Scenario: A Citrix Administrator is configuring load balancing on a Citrix ADC appliance for company web servers. The administrator needs to create a custom monitor that will look for a specific keyword response from the website, which will be used to keep services in an UP state.

Which monitor can the administrator create to meet this requirement?

Options:

An HTTP-ECV monitor with the keyword in the Special Parameters - Receive String field

An HTTP-ECV monitor with the keyword in the Basic Parameters - Receive String field

An HTTP-ECV monitor with the keyword in the Special Parameters - Receive String field, and the Reverse option enabled

An HTTP-ECV monitor with the keyword in the Basic Parameters - Send String field

Answer:

Explanation:

Correct Answer: B. An HTTP-ECV monitor with the keyword in the Basic Parameters - Receive String field

Short Explanation with reference:

An HTTP-ECV (Extended Content Verification) monitor is a type of monitor that allows the Citrix ADC appliance to check the health and availability of the web servers by sending HTTP requests and verifying the responses. An HTTP-ECV monitor can be configured with different parameters, such as Send String, Receive String, and Reverse, to customize the monitoring behavior. The Send String parameter specifies the HTTP request line that the monitor sends to the server. The Receive String parameter specifies the expected response from the server that indicates a successful probe. The Reverse parameter specifies whether to mark the service as UP or DOWN based on the presence or absence of the Receive String in the response.

In this scenario, the administrator needs to create a custom monitor that will look for a specific keyword response from the website, which will be used to keep services in an UP state. To meet this requirement, the administrator can create an HTTP-ECV monitor with the keyword in the Basic Parameters - Receive String field. This will make the monitor expect the keyword in the response from the server, and mark the service as UP if it finds it. The other options are incorrect, as they either use the wrong parameter or the wrong option for the monitoring task. For example, option A uses the Special Parameters - Receive String field, which is not a valid parameter for an HTTP-ECV monitor. Option C uses the Reverse option, which will make the monitor mark the service as DOWN if it finds the keyword in the response. Option D uses the Basic Parameters - Send String field, which will make the monitor send the keyword to the server, instead of looking for it in the response.

Question 26

Scenario: A Citrix Administrator needs to configure a Responder policy, so that the string “/mytraining” is added

to every URL path received.

The administrator should use these commands to accomplish this:

>add responder action Redirect_Act redirect “HTTP.REQ.URL.PATH_AND_QUERY+\”mytraining\”” –

responseStatusCode 302

>add responder policy Redirect_Pol___________Redirect_Act

>bind lb vServer lb_vsrv_www –policyName Redirect_Pol –priority 100 –gotoPriorityExpression END –

type_______

(Choose the correct option to complete the set of commands.)

Options:

“(HTTP.REQ.URL.STARTSWITH(\”mytraining\”))”

REQUEST

“(HTTP.REQ.URL.STARTSWITH(\”mytraining\”))”

RESPONSE

“!(HTTP.REQ.URL.ENDSWITH(\”mytraining\”))”

REQUEST

“!(HTTP.REQ.URL.ENDSWITH(\”mytraining\”))”

RESPONSE

Question 27

When a Citrix ADC high availability (HA) pair failover occurs, by what method does the Citrix ADC communicate to the network switches and routers that IP-to-MAC address bindings have changed?

Options:

Reverse ARP (RARP) to update the network devices

MAC-based forwarding (MBF) to update the routers

Proxy ARP to update the network devices

Gratuitous ARPs (GARPs) to update the network devices

Question 28

Scenario: After deploying a Citrix ADC in production, a Citrix Administrator notices that client requests are NOT being evenly distributed among backend resources. The administrator wants to change from the default loadbalancing method to one that will help distribute the load more evenly.

Which load-balancing method would ensure that the server with the least amount of network utilization is receiving new connections?

Options:

Least connection

Least bandwidth

Least response time

Least packets
