VMware 2V0-41.24 Online Questions & Answers

• Question 1:

  HOTSPOT

  An administrator configured NSX Advanced Load Balancer to load balance the production web server traffic, but the end users are unable to access the production website by using the VIP address.

  Which of the following Tier-1 gateway route advertisement settings needs to be enabled to resolve the problem? Mark the correct answer by clicking on the image.

  

  

  Explanation

  The correct answer is to enable the option All LB VIP Routes on the Tier-1 gateway route advertisement settings. This option allows the Tier-1 gateway to advertise the NSX Advanced Load Balancer LB VIP routes to the Tier-0 gateway and

  other peer routers, so that the end users can reach the production website by using the VIP address. The other options are not relevant for this scenario.

  To mark the correct answer by clicking on the image, you can click on the toggle switch next to All LB VIP Routes to turn it on. The switch should change from gray to blue, indicating that the option is enabled.

• Question 2:

  HOTSPOT

  An administrator configured NSX Advanced Load Balancer to redistribute the traffic between the web servers. However, requests are sent to only one server Which of the following pool configuration settings needs to be adjusted to resolve the problem? Mark the correct answer by clicking on the image.

  

  

  Explanation

  Load Balancing Algorithm

  You specify the following parameters during the creation of a server pool:

  Name: A unique name for the server pool.

  Cloud: The cloud connector details for the NSX environment.

  VRF Context: Virtual Routing Framework (VRF) is a method to isolate traffic in a system. VRF is also called a route domain in the load balancer community. A global VRF context is created by default. Network administrators might create

  custom VRF contexts to isolate traffic between different tenants or subsets.

  Default Server Port: New connections to servers will use this destination service port. The default port is 80.

  Load-balancing algorithm: The selected load-balancing algorithm controls how the incoming connections are distributed among the servers in the pool.

  Tier-1 gateway (logical router): Specify the Tier-1 gateway that you want to attach the server pool to. This value matches the Tier-1 gateway specified for the virtual service and VIP.

• Question 3:

  DRAG DROP

  Sort the rule processing steps of the Distributed Firewall. Order responses from left to right.

  Select and Place:

  

  

  Explanation

  The correct order of the rule processing steps of the Distributed Firewall is as follows:

  Packet arrives at vfilter connection table. If matching entry in the table, process the packet.

  If connection table has no match, compare the packet to the rule table. If the packet matches source, destination, service, profile and applied to fields, apply the action defined.

  If the rule table action is allow, create an entry in the connection table and forward the packet.

  If the rule table action is reject or deny, take that action. This order is based on the description of how the Distributed Firewall works in the web search results. The first step is to check if there is an existing connection entry for the packet in the vfilter connection table, which is a cache of flow entries for rules with an allow action. If there is a match, the packet is processed according to the connection entry. If there is no match, the packet is compared to the rule table, which contains all the security policy rules. The rules are evaluated from top to bottom until a match is found. The match criteria include source, destination, service, profile and applied to fields. The action defined by the matching rule is applied to the packet.

  The action can be allow, reject or deny. If the action is allow, a new connection entry is created for the packet and the packet is forwarded to its destination. If the action is reject or deny, the packet is dropped and an ICMP message or a TCP reset message is sent back to the source.

• Question 4:

  DRAG DROP

  Drag and drop the NSX graphic element icons on the left found in an NSX Intelligence visualization graph to Its correct description on the right.

  Select and Place:

• Question 5:

  What must be configured on Transport Nodes for encapsulation and decapsulation of Geneve protocol?

  A. TEP
  B. STT
  C. VXLAN
  D. UDP
  A. TEP

  ---

  explanation:

  Explanation

  TEP (Tunnel Endpoint): TEPs (Tunnel Endpoints) are configured on transport nodes to handle the encapsulation and decapsulation of the Geneve protocol. TEPs are responsible for creating the overlay network by encapsulating traffic in the Geneve protocol when it moves between transport nodes and decapsulating it upon arrival.

• Question 6:

  Which two of the following are used to configure Distributed Firewall on VDS? (Choose two.)

  A. vSphere API
  B. NSX API
  C. NSX CU
  D. vCenter API
  E. NSX UI
  B. NSX API
  E. NSX UI

  ---

  explanation:

  Explanation

  According to the VMware NSX Documentation, these are two of the ways that you can use to configure Distributed Firewall on VDS:

  NSX API: This is a RESTful API that allows you to programmatically configure and manage Distributed Firewall on VDS using HTTP methods and JSON payloads. You can use tools such as Postman or curl to send API requests to the NSX

  Manager node.

  NSX UI: This is a graphical user interface that allows you to configure and manage Distributed Firewall on VDS using menus, tabs, buttons, and forms. You can access the NSX UI by logging in to the NSX Manager node using a web browser.

• Question 7:

  Which choice is a valid insertion point for North-South network introspection?

  A. Host Physical NIC
  B. Tier-0 gateway
  C. Guest VM vNIC
  D. Partner SVM
  B. Tier-0 gateway

  ---

  explanation:

  Explanation

  The Tier-0 gateway is the valid insertion point for North-South network introspection in an NSX environment. North-South traffic refers to traffic entering or leaving the data center, and the Tier-0 gateway is responsible for routing this traffic between the NSX environment and external networks. Placing network introspection at the Tier-0 gateway allows for inspection and security policies to be applied to traffic as it moves in and out of the data center.

• Question 8:

  Which three DHCP Services are supported by NSX? (Choose three.)

  A. Gateway DHCP
  B. Segment DHCP
  C. DHCP Relay
  D. Port DHCP per VNF
  E. VRF DHCP Server
  A. Gateway DHCP
  B. Segment DHCP
  C. DHCP Relay

  ---

  explanation:

  Explanation

  Gateway DHCP: NSX supports DHCP services configured on the gateway, allowing it to provide IP addresses to clients within the network. Segment DHCP: NSX can provide DHCP services at the segment level, where DHCP is configured directly on a network segment to assign IP addresses to connected clients. DHCP Relay: NSX supports DHCP Relay, which allows forwarding of DHCP requests to an external DHCP server for IP address assignment.

• Question 9:

  Where can an administrator see a visual overview of network connections between different VMs and different networks, within the NSX domain?

  A. Network Intelligence
  B. NSX Intelligence
  C. VMware Aria Operations
  D. VMware Aria Operations for Networks
  B. NSX Intelligence

  ---

  explanation:

  Explanation

  NSX Intelligence provides a visual overview of network connections within the NSX domain, allowing administrators to see the traffic flows between different VMs and networks. It offers detailed visibility into network traffic patterns, application dependencies, and security posture, making it a valuable tool for monitoring and troubleshooting within NSX environments.

• Question 10:

  When a stateful service is enabled for the first time on a Tier-0 Gateway, what happens on the NSX Edge node?

  A. DR is instantiated and automatically connected with SR.
  B. SR is instantiated and automatically connected with DR.
  C. SR and DR doesn't need to be connected to provide any stateful services.
  D. SR and DR is instantiated but requires manual connection.
  B. SR is instantiated and automatically connected with DR.

  ---

  explanation:

  Explanation

  When a stateful service (such as NAT or firewall) is enabled for the first time on a Tier-0 Gateway, the Service Router (SR) is instantiated on the NSX Edge node and automatically connected with the Distributed Router (DR). This connection enables the Tier-0 Gateway to handle stateful services by routing traffic through the SR, which manages stateful packet processing, while the DR provides distributed routing functionality.
