VMware 2V0-41.23 Practice Test - Questions Answers, Page 4

According to the web search results, VMware Aria Operations Networks (formerly vRealize Network Insight) is a network monitoring tool that can help monitor, discover and analyze networks and applications across clouds1.It can also provide enhanced troubleshooting and visibility for physical and virtual networks2.

The other options are either incorrect or not relevant for identifying problems in a physical network. VMware Aria Automation is a cloud automation platform that can help automate the delivery of IT services. VMware Aria Orchestrator is a cloud orchestration tool that can help automate workflows and integrate with other systems. VMware Site Recovery Manager is a disaster recovery solution that can help protect and recover virtual machines from site failures.

According to the VMware NSX Documentation, these are the prerequisites for adding nodes to an NSX Management Cluster using the NSX UI:

All nodes must be in the same subnet and have IP connectivity with each other.

A compute manager must be configured and associated with the NSX Manager node.

The NSX Manager node must have a valid license.

The NSX Manager node must have a valid certificate.

According to the VMware NSX Documentation, these are two of the use cases for Distributed Intrusion Detection, which is a feature of NSX Network Detection and Response:

Quarantine workloads based on vulnerabilities: You can use Distributed Intrusion Detection to detect vulnerabilities in your workloads and apply quarantine actions to isolate them from the network until they are remediated.

Identify security vulnerabilities in the workloads: You can use Distributed Intrusion Detection to scan your workloads for known vulnerabilities and generate reports that show the severity, impact, and remediation steps for each vulnerability.

according to the VMware NSX Documentation, these are the three parameters that must match in order to establish an OSPF neighbor relationship with an upstream router on a tier-0 gateway:

MTU of the Uplink: The maximum transmission unit (MTU) of the uplink interface must match the MTU of the upstream router interface. Otherwise, OSPF packets may be fragmented or dropped, causing neighbor adjacency issues.

Subnet mask: The subnet mask of the uplink interface must match the subnet mask of the upstream router interface. Otherwise, OSPF packets may not reach the correct destination or be rejected by the upstream router.

Area ID: The area ID of the uplink interface must match the area ID of the upstream router interface. Otherwise, OSPF packets may be ignored or discarded by the upstream router.

The NSX Application Platform Deployment features are divided into three form factors: Evaluation, Standard, and Advanced.Each form factor determines which NSX features can be activated or installed on the platform1.The Evaluation form factor supports only NSX Intelligence, which provides network visibility and analytics for NSX-T environments2.The Standard form factor supports both NSX Intelligence and NSX Network Detection and Response, which provides network threat detection and response capabilities for NSX-T environments3.The Advanced form factor supports all four features: NSX Intelligence, NSX Network Detection and Response, NSX Malware Prevention, and NSX Metrics1.

The service interface is a special-purpose port to enable services for mainly VLAN-based networks. North-south service insertion is another use case that requires a service interface to connect a partner appliance and redirect north-south traffic for partner services. Service interfaces are supported on both active-standby Tier-0 logical routers and Tier-1 routers. Firewall, NAT, and VPNs are supported on this interface. The service interface is also a downlink

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.

According to the web search results, network segmentation is a feature of NSX that improves the security of today's modern workloads by preventing lateral movement. Lateral movement is a technique used by attackers to move from one compromised system to another within a network, exploiting vulnerabilities or credentials . Network segmentation prevents lateral movement by dividing a network into smaller segments or zones, each with its own security policies and controls. This way, if one segment is compromised, the attacker cannot access other segments or resources . NSX enables network segmentation by using micro-segmentation, which applies granular firewall rules at the virtual machine level, regardless of the physical network topology .

BGP will be configured on the T0 SR. Connect to the VRF for the T0 SR and run get bgp neighbor once connected to it. https://docs.vmware.com/en/VMware-Validated-Design/5.1/sddc-deployment-of-vmware-nsx-t-workload-domains-with-multiple-availability-zones/GUID-8BD4228A-75C6-4C60-80B4-538D4297E11A.html

For the BGP configuration on NSX-T, the Tier-0 Service Router (SR) is typically where BGP is configured. To check the BGP neighbor status:

Connect to the VRF for the T0 SR, which is VRF 3 based on the provided output.

Run the command to get BGP neighbor status once connected to it.
