Correct Answer: DEF

According to the VMware NSX 4.x Professional documents and tutorials, an NSX Manager is a standalone appliance that hosts the API services, the management plane, control plane, and policy management. The NSX Manager has three built-in roles: policy, manager, and controller2. The policy role handles the declarative configuration of the system and translates it into desired state for the manager role. The manager role receives and validates the configuration from the policy role and stores it in a distributed persistent database. The manager role also publishes the configuration to the central control plane. The controller role implements the central control plane that computes the network state based on the configuration and topology information3. The other roles (master, cloud, and zookeeper) are not valid NSX Manager roles.

Correct Answer: D

The Traceflow tool identifies issues in a network by injecting synthetic traffic into the data plane and observing the results in the control plane. This allows the tool to identify any issues in the network and provide a detailed report on the problem. You can use the Traceflow tool to test connectivity between any two endpoints in your NSX-T Data Center environment.

Correct Answer: AE

A group is a logical construct that represents a collection of objects in NSX, such as segments, segment ports, virtual machines, IP addresses, MAC addresses, tags, or security policies. A group can be used to define dynamic membership criteria based on various attributes or filters. A group can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that matches the group membership criteria32 Reference: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-41CC06DF-1CD4-4233-B43E-492A9A3AD5F6.html https://docs.vmware.com/en/VMware-NSX-Data-Center-for-vSphere/6.4/ com.vmware.nsx.admin.doc/GUID-D44C8923-992F-4695-B9C0-5CC271679D09.html

Correct Answer: A

According to the VMware NSX Documentation, this VPN type must be configured before enabling a L2VPN. L2VPN stands for Layer 2 VPN and is a feature that allows you to extend your layer 2 network across different sites using an IPSec tunnel. Route-based IPSec VPN is a VPN type that uses logical router ports to establish IPSec tunnels between sites. https://docs.vmware.com/en/VMware-NSX/4.1/administration/GUID-86C8D6BB-F185-46DC-828C-1E1876B854E8.html

Correct Answer: AD

AS-Path Prepend: This attribute allows you to prepend one or more AS numbers to the AS path of a route, making it appear longer and less preferable to other BGP routers. You can use this attribute to manipulate the inbound traffic from

your BGP peers by advertising a longer AS path for some routes and a shorter AS path for others .

MED: This attribute stands for Multi-Exit Discriminator and allows you to specify a preference value for a route among multiple exit points from an AS. You can use this attribute to manipulate the outbound traffic to your BGP peers by

advertising a lower MED value for some routes and a higher MED value for others .

Correct Answer: A

According to the VMware NSX Documentation, a non-preemptive failover policy means that the original failed node will not become the active node upon recovery, unless the current active node fails again. This policy can help avoid

unnecessary failovers and ensure stability.

The other options are either incorrect or not available for this configuration. Preemptive is the opposite of non-preemptive, meaning that the original failed node will become the active node upon recovery, if it has a higher priority than the

current active node. Enable Preemptive and Disable Preemptive are not valid options for the failover policy, as the failover policy is a drop-down menu that only has two choices: Preemptive and Non-Preemptive.

Correct Answer: C

According to the VMware Knowledge Base, this CLI command is used for packet capture on the ESXi node. pktcap-uw stands for Packet Capture User World and is a tool that allows you to capture packets from various points in the network

stack of an ESXi host. You can use this tool to troubleshoot network issues or analyze traffic flows. The other options are either incorrect or not available for this task. tcpdump is not a valid CLI command for packet capture on the ESXi node,

as it is a tool that runs on Linux systems, not on ESXi hosts. debug is not a valid CLI command for packet capture on the ESXi node, as it is a generic term that describes the process of finding and fixing errors, not a specific tool or command.

set capture is not a valid CLI command for packet capture on the ESXi node, as it does not exist in the ESXi CLI.

Correct Answer: DF

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-withmultiple-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.

Correct Answer: BCD

The main components on the edge node for north-south malware prevention perform the following functions:

?IDS/IPS engine: Extracts files and relays events and data to the security hub North-south malware prevention uses the file extraction features of the IDS/IPS engine that runs on NSX Edge for north-south traffic. ?Security hub: Collects file events, obtains verdicts for known files, sends files for local and cloud-based analysis, and sends information to the security analyzer ?RAPID: Provides local analysis of the file ?ASDS Cache: Caches reputation and verdicts of known files

Correct Answer: D

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

Correct Answer: ACF

Correct Answer: B

Route-based VPN is a VPN type that uses Virtual Tunnel interfaces (VTI) to establish IPSec tunnels between an NSX Edge node and remote sites2. A VTI is a logical interface that is assigned an IP address and is associated with a physical or virtual interface. The VTI acts as an end point of the IPSec tunnel and routes traffic between the NSX Edge node and the remote site2. Route and SSL based VPNs, Policy and Route based VPNs, and SSL-based VPN are not VPN types that use VTI. References: Virtual Private Network (VPN)

Correct Answer: BE

The host switch modes determine how the NSX network and security stack is allocated on the underlying host CPU or DPU. There are two supported host switch modes: Enhanced Datapath and Standard Datapath1. Enhanced Datapath mode leverages the DPU to offload the NSX datapath processing from the host CPU, while Standard Datapath mode uses the host CPU for the NSX datapath processing1. DPDK Datapath, Overlay Datapath, and Secure Datapath are not valid host switch modes for NSX 4.x. References: NSX Features

Correct Answer:

Security policy recommendations: Are East-West distributed firewall (DFW) security policies in the application category12.

Security group recommendations: Are VMs or physical servers whose traffic flows were analyzed for the time period and the boundary you had specified12. Service recommendations: Are service objects that were used by applications in the

VMs or physical servers that you had specified, but the services are not yet defined in the NSX inventory12.
