Free VMware 2V0-41.23 Practice Exam with Questions & Answers | Set: 2

The correct answers are A. Files and anti-malware (file) events from the NSX Edge nodes and the Security Analyzer, D. IDS/IPS events from the ESXi hosts and NSX Edge nodes, and E. Suspicious Traffic Detection events from NSX Intelligence. According to the VMware NSX Documentation3, these are the three data collection sources that are used by NSX Network Detection and Response to create correlations/intrusion campaigns.

The other options are incorrect or not supported by NSX Network Detection and Response. East-West anti-malware events from the ESXi hosts are not collected by NSX Network Detection and Response3. Distributed Firewall flow data from the ESXi hosts are not used for correlation/intrusion campaigns by NSX Network Detection and Response3.

According to the web search results, error code 1001 is related to a time synchronization issue between the ESXi host and the NSX Manager. This can cause problems when configuring a time-based firewall rule, which requires the ESXi host and the NSX Manager to have the same time zone and NTP server settings . To resolve this error, you need to restart the NTP service on the ESXi host to synchronize the time with the NSX Manager. You can use the following command to restart the NTP service on the ESXi host:

/etc/init.d/ntpd restart

The other options are not valid solutions for this error. Reinstalling the NSX VIBs on the ESXi host will not fix the time synchronization issue. Changing the time zone on the ESXi host may cause more discrepancies with the NSX Manager. Reconfiguring the ESXi host with a local NTP server may not be compatible with the NSX Manager’s NTP server.

The sequence of commands that could be used to check the BGP connection status between the Tier-O Gateway and the upstream physical router on NSX Edge node is get gateways, vrf , get bgp neighbor. These commands can be executed on the NSX Edge node CLI after logging in as admin6. The first command, get gateways, displays the list of logical routers (gateways) configured on the Edge node, along with their IDs and VRF numbers7. The second command, vrf , switches to the VRF context of the desired Tier-O Gateway, where is the VRF number obtained from the previous command7. The third command, get bgp neighbor, displays the BGP neighbor summary for the selected VRF, including the neighbor IP address, AS number, state, uptime, and prefixes received8. The other options are incorrect because they either use invalid or incomplete commands or do not switch to the correct VRF context. References: NSX-T Command-Line Interface Reference, NSX Edge Node CLI Commands, Troubleshooting BGP on NSX-T Edge Nodes

The following L2 VPN clients are recommended:

1. NSX Managed NSX Edge in a separate NSX Managed environment.

• Overlay and VLAN segments can be extended.

2. Autonomous Edge:

• Enables L2 VPN access from a non-a NSX environment to NSX environments.

• Deployed by using an OVF file on a host that is not managed by NSX.

• Only VLAN segments can be extended.

According to the VMware NSX 4.x Professional documents and tutorials, a RouterLink port is a logical port that connects a Tier-1 gateway to a Tier-0 gateway. This port is automatically created when a Tier-1 gateway is associated with a Tier-0 gateway from the NSX UI or API. The RouterLink port enables routing between the two gateways and carries all the routing protocols and traffic. There is no need to manually create a logical switch or segment for this purpose1.

According to the VMware Knowledge Base article 1, the CLI command to set the log level of the NSX Manager to debug mode is set service manager logging-level debug. This command can be used when the NSX UI is inaccessible or when troubleshooting issues with the NSX Manager1. The other commands are incorrect because they either use a wrong syntax or a wrong service name. The NSX Manager service name is manager, not nsx-manager2. The log level parameter is logging-level, not log-level3.

 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.

Network Introspection is a service insertion feature that allows third-party network security services to monitor and analyze the traffic between virtual machines. Network Introspection can be configured on the host pNIC or on the partner SVM, depending on the type of service and the deployment model. The host pNIC configuration is used for services that require traffic redirection from the physical network to the service virtual machine. The partner SVM configuration is used for services that require traffic redirection from the virtual network to the service virtual machine. Network Introspection cannot be configured on the Tier-0 or Tier-1 gateways, as they are not part of the data plane where the service insertion occurs. Network Introspection also cannot be configured on the edge node, as it is a logical construct that hosts the Tier-0 and Tier-1 gateways. References: Distributed Service Insertion, NSX Securing “Anywhere” Part IV

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. References: NSX-T Edge TEP networking options, Multi-TEP High Availability, Create an IP Pool for Host Tunnel Endpoint IP Addresses

To configure NSX Manager for two-factor authentication (2FA), an NSX administrator must have VMware Identity Manager (vIDM) with an OAuth Client added. vIDM provides identity management services and supports various 2FA methods, such as VMware Verify, RSA SecurID, and RADIUS. An OAuth Client is a configuration entity in vIDM that represents an application that can use vIDM for authentication and authorization. NSX Manager must be registered as an OAuth Client in vIDM before it can use 2FA. References: : VMware NSX-T Data Center Installation Guide, page 19. : VMware NSX-T Data Center Administration Guide, page 102. : VMware Blogs: Two-Factor Authentication with VMware NSX-T
