An NSX administrator wants to create a Tler-0 Gateway to support equal cost multi-path (ECMP) routing. Which failover detection protocol must be used to meet this requirement?
Correct Answer: A
Explanation According to the VMware NSX 4.x Professional documents and tutorials, BFD is a failover detection protocol that provides fast and reliable detection of link failures between two routing devices. BFD can be used with ECMP routing to monitor the health of the ECMP paths and trigger a route change in case of a failure12. BFD is supported by both BGP and OSPF routing protocols in NSX-T3. BFD can also be configured with different timers to achieve different detection times3.
Question 62
Which TraceFlow traffic type should an NSX administrator use tor validating connectivity between App and DB virtual machines that reside on different segments?
Correct Answer: B
Explanation Unicast is the traffic type that an NSX administrator should use for validating connectivity between App and DB virtual machines that reside on different segments. According to the VMware documentation1, unicast traffic is the traffic type that is used to send a packet from one source to one destination. Unicast traffic is the most common type of traffic in a network, and it is used for applications such as web browsing, email, file transfer, and so on2. To perform a traceflow with unicast traffic, the NSX administrator needs to specify the source and destination IP addresses, and optionally the protocol and related parameters1. The traceflow will show the path of the packet across the network and any observations or errors along the way3. The other options are incorrect because they are not suitable for validating connectivity between two specific virtual machines. Multicast traffic is the traffic type that is used to send a packet from one source to multiple destinations simultaneously2. Multicast traffic is used for applications such as video streaming, online gaming, and group communication4. To perform a traceflow with multicast traffic, the NSX administrator needs to specify the source IP address and the destination multicast IP address1. Broadcast traffic is the traffic type that is used to send a packet from one source to all devices on the same subnet2. Broadcast traffic is used for applications such as ARP, DHCP, and network discovery. To perform a traceflow with broadcast traffic, the NSX administrator needs to specify the source IP address and the destination MAC address as FF:FF:FF:FF:FF:FF1. Anycast traffic is not a valid option, as it is not supported by NSX Traceflow. Anycast traffic is a traffic type that is used to send a packet from one source to the nearest or best destination among a group of devices that share the same IP address. Anycast traffic is used for applications such as DNS, CDN, and load balancing.
Question 63
Which command on ESXI is used to verify the Local Control Plane connectivity with Central Control Plane?
Correct Answer: B
Explanation According to the web search results, the command that is used to verify the Local Control Plane (LCP) connectivity with Central Control Plane (CCP) on ESXi is get control-cluster status. This command displays the status of the LCP and CCP components on the ESXi host, such as the LCP agent, CCP client, CCP server, and CCP connection. It also shows the IP address and port number of the CCP server that the LCP agent is connected to. If the LCP agent or CCP client are not running or not connected, it means that there is a problem with the LCP connectivity .
Question 64
What should an NSX administrator check to verify that VMware Identity Manager Integration Is successful?
Correct Answer: B
Explanation From the NSX UI the status of the VMware Identity Manager Integration must be "Enabled". According to the VMware NSX Documentation1, after configuring VMware Identity Manager integration, you can validate the functionality by checking the status of the integration in the NSX UI. The status should be "Enabled" if the integration is successful. The other options are either incorrect or not relevant.
Question 65
When deploying an NSX Edge Transport Node, what two valid IP address assignment options should be specified for the TEP IP addresses? (Choose two.)
Correct Answer: A,D
Explanation When deploying an NSX Edge Transport Node, two valid IP address assignment options that should be specified for the TEP IP addresses are Use an IP Pool and Use a Static IP List. These options allow the user to assign TEP IP addresses from a predefined range of IP addresses or a manually entered list of IP addresses, respectively345. The other options are incorrect because they are not supported methods for assigning TEP IP addresses. There is no option to use a DHCP server, RADIUS, or BootP for TEP IP address assignment in NSX-T345.
