Citrix 1Y0-241 Dumps

By binding a multiple SAN certificate, we only need to adapt the DNS entries of the websites to point to the same IP (1 IP with 3 DNS) and we will be able to forward the requests to any backend server since all of them are serving the same content.

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.

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: C. POL_14

Short Explanation with reference:

The Citrix ADC appliance evaluates the rewrite policies in the order of their priority, from lowest to highest. The priority is a numerical value that indicates the relative importance of the policy. The lower the priority, the higher the importance. The gotoPriorityExpression is an expression that specifies the next policy to evaluate after the current policy is hit. The expression can be either a priority value or the keyword END, which indicates that no further policies are evaluated. Therefore, in this scenario, the policy evaluation order is as follows:

• POL_12 is hit first, as it has the lowest priority (90). It has a gotoPriorityExpression of NEXT, which means that the next policy in priority order is evaluated.
• POL_15 is evaluated next, as it has the next lowest priority (100). It has a gotoPriorityExpression of END, which means that no further policies are evaluated.
• POL_13 and POL_14 are not evaluated, as they have higher priorities (101 and 120) than POL_15, and POL_15 has a gotoPriorityExpression of END.

Therefore, the correct answer is C. POL_14, as it is the policy that is evaluated last, considering POL_12 is hit first.

Correct Answer: C. CLIENT and D. DNS

Short Explanation with reference:

When creating advanced policies, you can use the following expression prefixes: HTTP, SYS, CLIENT, SERVER, DNS, DATE, TIME, and URL1. TCP and IP are not valid prefixes for advanced policies2. SQL is not a supported feature for advanced policies3.

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: D.

Short Explanation with reference:

A rewrite policy is a set of rules that defines how the Citrix ADC appliance modifies the requests and responses that it processes. A rewrite policy consists of an expression that evaluates to true or false, and an action that specifies what modification to perform. A rewrite action can use the replace_all function to replace all occurrences of a pattern in a string with another string.

In an SSL offload deployment, the Citrix ADC appliance terminates the SSL traffic from the clients and forwards the clear text traffic to the servers. This can cause a problem if the response body from the servers contains URLs that start with as they will not match the protocol of the original request, which was To fix this problem, the administrator can use a rewrite policy to modify all URLs in the response body from to

The correct policy for this task is D, as it uses the replace_all function to replace all occurrences of with in the HTTP response body. The other policies are incorrect, as they either use the wrong pattern or the wrong replacement string. For example, policy A replaces with which is the opposite of what is required. Policy B uses an incorrect escape character (“ ") before the colon (”:“) in both the pattern and the replacement string. Policy C uses a space (” “) instead of a colon (”:") in the replacement string.

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: B. Two-arm

Short Explanation with reference:

A two-arm deployment is a common scenario where the Citrix ADC appliance has two network interfaces, one connected to the DMZ network and the other connected to the internal network1. This allows the appliance to act as a gateway between the two networks and provide load balancing, security, and optimization features for the applications hosted on the internal servers2. A two-arm deployment also provides better isolation and protection for the internal network than a one-arm deployment, where the appliance has only one network interface connected to a switch or router that spans both networks3. A transparent mode is a packet forwarding mode that enables the appliance to act as a Layer 2 device and bridge packets that are not destined for it4. A forward proxy mode is a feature that enables the appliance to act as an intermediary between clients and servers on the internet, caching web content and applying policies. Neither of these modes are relevant for the scenario described in the question.

During startup of a virtual server, or whenever the state of a virtual server changes, the virtual server can initially use the round-robin method to distribute the client requests among the physical servers. This type of distribution, referred to as startup round robin, helps prevent unnecessary load on a single server as the initial requests are served. After using the round-robin method at the startup, the virtual server switches to the loadbalancing method specified on the virtual server

Correct Answer: D. Round-robin

Short Explanation with reference:

A load-balancing vServer is a virtual server that distributes the incoming traffic among a group of services that provide the same content or functionality. A load-balancing vServer can use different load-balancing methods to select the best service for each request, based on various criteria, such as availability, performance, or load. The least bandwidth load-balancing method selects the service that is currently handling the least amount of traffic, measured in megabits per second.

However, during the startup of a vServer, the least bandwidth load-balancing method is not used by default. This is because the Citrix ADC appliance does not have enough data to calculate the bandwidth usage of each service at the beginning. Therefore, the appliance uses the round-robin load-balancing method by default, which selects the services in a circular order, without any weighting or priority. The round-robin load-balancing method is also used as a fallback method when other load-balancing methods fail or are not applicable.

Therefore, the correct answer is D. Round-robin.
