Citrix 1Y0-241 Deploy and Manage Citrix ADC with Traffic Management Exam Practice Test

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.

Correct Answer: D. CLIENT.IP.SRC IN_SUBNET(10.107.149.0/24) && (client.UDP.DSTPORT.EQ(53) || client.TCP.DSTPORT.EQ(53))

Short Explanation with reference:

An expression is a logical statement that evaluates to true or false, and can be used to match the required traffic for various purposes, such as filtering, rewriting, or load balancing. An expression can use different operators, functions, and values to specify the criteria for matching the traffic. Some of the common elements of an expression are:

• CLIENT.IP.SRC: This function returns the source IP address of the client request.
• IN_SUBNET: This operator checks whether an IP address belongs to a specified subnet.
• &&: This operator performs a logical AND operation between two expressions.
• ||: This operator performs a logical OR operation between two expressions.
• client.UDP.DSTPORT and client.TCP.DSTPORT: These functions return the destination port of the client request for UDP and TCP protocols, respectively.
• EQ: This operator checks whether two values are equal.

In this scenario, the administrator needs to block all DNS requests from subnet 10.107.149.0/24. DNS requests are typically sent over UDP or TCP protocols, and use port 53 as the destination port. Therefore, the expression that can match this traffic is:

CLIENT.IP.SRC IN_SUBNET(10.107.149.0/24) && (client.UDP.DSTPORT.EQ(53) || client.TCP.DSTPORT.EQ(53))

This expression evaluates to true if the source IP address of the client request is in the subnet 10.107.149.0/24, and the destination port of the client request is 53 for either UDP or TCP protocol.

The other options are incorrect, as they either use the wrong function, operator, or syntax for matching the traffic. For example, option A uses the SRC function instead of the IN_SUBNET operator, which will only match a single IP address instead of a subnet. Option B uses an incorrect delimiter (space) between the subnet address and mask, which will cause a syntax error. Option C uses parentheses incorrectly, which will change the order of evaluation and result in a different meaning.

Correct Answer: A. Citrix Application Delivery Management (ADM)

Short Explanation with reference: Citrix Application Delivery Management (ADM) is a web-based tool that provides end-to-end visibility and management for Citrix ADC deployments. It also enables administrators to view real-time and historical data on response time, client network latency, and server-side processing time for applications that are load balanced on the Citrix ADC1. HDX Insight, WAN Insight, and Security Insight are features of Citrix ADM that provide specific insights for HDX traffic, WAN optimization, and security events respectively1. They are not standalone tools that can be used to gather information on latency and response time. Therefore, the correct answer is A. Citrix Application Delivery Management (ADM).

Correct Answer: A. The GSLB services will be marked as DOWN if the MEP connection has been DOWN for 10 seconds.

Short Explanation with reference: The GSLBSvcStateDelayTime parameter is used to set the amount of delay in updating the state of GSLB service to DOWN when MEP goes down1. This parameter is applicable only if monitors are not bound to GSLB services1. By default, the value of this parameter is 0, which means that the GSLB service state is updated immediately when MEP goes down1. However, if the value of this parameter is set to a positive number, such as 10, then the GSLB service state is updated after that number of seconds when MEP goes down1. This can help avoid unnecessary disruption of services due to temporary MEP failures2. Therefore, the effect of the above command on the GSLB environment is that the GSLB services will be marked as DOWN if the MEP connection has been DOWN for 10 seconds. The other options are incorrect because they either do not involve the GSLBSvcStateDelayTime parameter or they do not reflect the correct relationship between MEP and GSLB service state. The correct answer is A. The GSLB services will be marked as DOWN if the MEP connection has been DOWN for 10 seconds.

Correct Answer: D. Virtual MAC

Short Explanation with reference:

Virtual MAC (VMAC) is a feature that allows the Citrix ADC appliance to use a common MAC address for both the primary and secondary units in a high availability (HA) pair1. This prevents the upstream router from having to update its ARP table when a failover occurs, as the MAC address of the active unit remains unchanged2. VMAC can be enabled or disabled by using the -vmac option in the CLI or by checking or unchecking the Enable VMAC check-box in the GUI1. Therefore, the correct answer is D. Virtual MAC.

To put a compression policy into effect, you must bind it either globally, so that it applies to all traffic that flows through the Citrix ADC, or to a specific virtual server, so that the policy applies only to requests whose destination is the VIP address of that virtual server.

By default, compression is disabled on the Citrix ADC. You must enable the feature before configuring it. You can enable it globally so that it applies to all HTTP and SSL services, or you can enable it just for specific services.

A sysadmin is lower than a superuser is terms of access allowed on the appliance. A sysadmin user can perform all Citrix ADC operations with the following exceptions: no access to the Citrix ADC shell, cannot perform user configurations, cannot perform partition configurations, and some other configurations as stated in the sysadmin command policy

Correct Answer: B. SDX

Short Explanation with reference: Citrix ADC SDX is a multi-tenant platform that allows multiple instances of Citrix ADC to run on a single physical appliance. Each instance is isolated from the others and has its own dedicated resources, configuration, and management. This enables service providers and enterprises to offer Citrix ADC as a service to their customers or internal departments, while maintaining security and operational consistency across any deployment12. Citrix ADC VPX, MPX, and CPX are single-tenant platforms that do not support multi-tenancy out of the box3.

The correct answer is D. Configure specific alerts for vServers using Citrix ADM.

Short Explanation with reference: Citrix Application Delivery Management (ADM) is a web-based tool that provides end-to-end visibility and management for Citrix ADC deployments. It also enables administrators to view real-time and historical data on response time, client network latency, and server-side processing time for applications that are load balanced on the Citrix ADC1. Citrix ADM allows administrators to create thresholds and alerts to monitor the state of a Citrix ADC instance, entity, or counter. When the value of a counter exceeds the threshold, Citrix ADM generates an event to signify a performance-related issue, and performs an action such as sending an alert, email, or SMS notification1.

To configure specific alerts for vServers using Citrix ADM, administrators need to follow these steps1:

• In Citrix ADM, navigate to Settings > Analytics Settings > Thresholds.
• Under Thresholds, click Add.
• On the Create Thresholds page, specify the following details:
• Click Create.

The other options are incorrect because they either do not allow setting specific thresholds and alerts for vServers, or they are used for different purposes. Network reporting (option A) and SMTP reporting (option B) are features of Citrix ADM that enable administrators to generate and send reports on network performance and statistics2. They do not allow setting thresholds and alerts for vServers. TCP Insight (option C) is a feature of Citrix ADM that provides detailed analytics of TCP traffic passing through the Citrix ADC instances3. It does not allow setting thresholds and alerts for vServers. Therefore, the correct answer is D. Configure specific alerts for vServers using Citrix ADM.

Correct Answer: A. Admin partitions that use dedicated VLANs

Short Explanation with reference: Admin partitions are a feature of Citrix ADC that allow administrators to create multiple logical partitions on a single physical appliance. Each partition is independent and isolated from the others, and has its own configuration, resources, and management. This enables administrators to delegate administration tasks to different departments or customers, while maintaining security and operational consistency1. Admin partitions can use dedicated VLANs to isolate the network traffic of each partition from the others2. A SNIP in each partition, and bind a VLAN for the department (option B) is also a valid way to isolate network traffic, but it does not provide configuration and management isolation. Policy-based routes for each department in the nsroot partition (option C) and dedicated routes in the admin partitions for each department (option D) are not relevant for isolating department-level administration, as they are used for routing traffic based on policies or routes3. Therefore, the correct answer is A. Admin partitions that use dedicated VLANs.

"Verify the URL and policy bindings. The client receives the 503 response when none of the policies you have configured is evaluated and no default load balancing virtual server is defined and bound to the content switching virtual server."

"Once default SSL Profiles are enabled, you cannot disable the default SSL Profiles."

Correct Answer: D. Purchase a Citrix ADC SDX appliance, and configure a Citrix ADC instance for each

Short Explanation with reference:

A Citrix ADC SDX appliance is a multi-tenant platform that allows the Citrix Administrator to create and manage multiple Citrix ADC instances on a single hardware device. Each instance is isolated and dedicated to a specific tenant or application, and can have its own resources, configuration, and features. A Citrix ADC SDX appliance can support up to 80 instances, depending on the model and license. A Citrix ADC SDX appliance can also provide high performance and scalability, as it can deliver up to 100 Gbps of throughput.

Therefore, to meet the needs of the newly acquired companies, the administrator can purchase a Citrix ADC SDX appliance, and configure a Citrix ADC instance for each company. This will give each company its own Citrix ADC for VPN access load balancing, and a minimum of 20 Gbps of throughput, as well as other benefits such as security, optimization, and availability.

Correct Answer: D. Session reuse

Short Explanation with reference:

Session reuse is a feature that allows the Citrix ADC appliance to reuse an existing SSL session between the client and the server, instead of creating a new one for each request1. This reduces the server load, improves response time, and increases the number of SSL transactions per second on an SSL vServer, as the session establishment process involves expensive cryptographic operations2. Session reuse is enabled by default on the Citrix ADC appliance, but it can be disabled or configured with different options1.

Correct Answer: B. Access Control List (ACL)

Short Explanation with reference:

An Access Control List (ACL) is a set of rules that can be used to allow or deny traffic to or from the Citrix ADC appliance1. A Citrix Administrator can use ACLs to restrict access to the NSIP address, which is the IP address used for management purposes2. By default, secure access to the NSIP address is enabled, but it can be disabled by using the -gui option in the CLI or by unchecking the Secure Access only check-box in the GUI2. Alternatively, a Citrix Administrator can also use the allowedManagementInterface parameter to define the list of permitted management interfaces for system users3.
