NEW QUESTION 1
As part of an organization's IT security compliance requirement, NSX Manager must be configured for 2FA (two-factor authentication).
What should an NSX administrator have ready before the integration can be configured? O

• A. Active Directory LDAP integration with OAuth Client added
• B. VMware Identity Manager with an OAuth Client added
• C. Active Directory LDAP integration with ADFS
• D. VMware Identity Manager with NSX added as a Web Application

Answer: B

Explanation:
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

NEW QUESTION 2
Which troubleshooting step will resolve an error with code 1001 during the configuration of a time-based firewall rule?

• A. Reinstalling the NSX VIBs on the ESXi host.
• B. Restarting the NTPservice on the ESXi host.
• C. Changing the lime zone on the ESXi host.
• D. Reconfiguring the ESXI host with a local NTP server.

Answer: B

Explanation:
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.

NEW QUESTION 3
Which command on ESXI is used to verify the Local Control Plane connectivity with Central Control Plane?
A)

B)

C)

D)

• A. Option A
• B. Option B
• C. Option C
• D. Option D

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 .

NEW QUESTION 4
Which command is used to set the NSX Manager's logging-level to debug mode for troubleshooting?

• A. Set service manager log-level debug
• B. Set service manager logging-level debug
• C. Set service nsx-manager log-level debug
• D. Set service nsx-manager logging-level debug

Answer: B

Explanation:
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.

NEW QUESTION 5
An administrator has deployed 10 Edge Transport Nodes in their NSX Environment, but has forgotten to specify an NTP server during the deployment.
What is the efficient way to add an NTP server to all 10 Edge Transport Nodes?

• A. Use Transport Node Profile
• B. Use the CU on each Edge Node
• C. Use a Node Profile
• D. Use a PowerCU script

Answer: C

Explanation:
A node profile is a configuration template that can be applied to multiple NSX Edge nodes or transport nodes at once. A node profile can include settings such as NTP server, DNS server, syslog server, and so on1. By using a node profile, an administrator can efficiently configure or update the network settings of multiple NSX Edge nodes or transport nodes in a single operation2. The other options are incorrect because they are either not efficient or not supported. Using the CLI on each Edge node would require manual and repetitive commands for each node, which is not efficient. Using a Transport Node Profile would not work, because a Transport Node Profile is used to configure the NSX-T Data Center components on a transport node, such as the transport zone, the N-VDS, and the uplink profiles3. Using a PowerCLI script might work, but it would require writing and testing a custom script, which is not as efficient as using a built-in feature like a node profile.

Where does an administrator configure the VLANs used In VRF Lite? (Choose two.)

• A. segment connected to the Tler-1 gateway
• B. uplink trunk segment
• C. downlink interface of the default Tier-0 gateway
• D. uplink Interface of the VRF gateway
• E. uplink interface of the default Tier-0 gateway

Answer: BD

Explanation:
According to the VMware NSX Documentation, these are the two places where you need to configure the VLANs used in VRF Lite:
Uplink trunk segment: This is a segment that connects a tier-0 gateway to a physical network using multiple VLAN tags. You need to configure the VLAN IDs for each VRF on this segment.
Uplink interface of the VRF gateway: This is an interface that connects a VRF gateway to an uplink trunk segment using a specific VLAN tag. You need to configure the VLAN ID for each VRF on this interface.

NEW QUESTION 8
Which CLI command does an NSX administrator run on the NSX Manager to generate support bundle logs if the NSX UI Is inaccessible?

• A. set support-bundle file vcpnv.tgz
• B. esxcli system syslog config logger set - -id=nsxmanager
• C. vm-support
• D. get support-bundle file vcpnv.tgz

Answer: D

Explanation:
To generate the support bundle logs on the NSX Manager via API, the NSX administrator needs to use the POST method with the URL https://nsxmgr_ip/api/1.0/appliance-management/techsupportlogs/NSX, where nsxmgr_ip is the IP address of the NSX Manager1. This will create a tech support bundle file with a name like vcpnv.tgz. To download the generated tech support bundle file via CLI, the NSX administrator needs to use the get support-bundle file vcpnv.tgz command on the NSX Manager1. The other commands are incorrect because they either do not generate or download the support bundle logs, or they are not related to the NSX Manager.

NEW QUESTION 9
When configuring OSPF on a Tler-0 Gateway, which three of the following must match in order to establish a neighbor relationship with an upstream router? (Choose three.)

• A. Naming convention
• B. MTU of the Uplink
• C. Subnet mask
• D. Address of the neighbor
• E. Protocol and Port
• F. Area ID

Answer: BCF

Explanation:
ccording 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.

NEW QUESTION 10
Which three DHCP Services are supported by NSX? (Choose three.)

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

Answer: ACE

Explanation:
According to the VMware NSX Documentation1, NSX-T Data Center supports the following types of DHCP configuration on a segment:
Local DHCP server: This option creates a local DHCP server that has an IP address on the segment and provides dynamic IP assignment service only to the VMs that are attached to the segment.
Gateway DHCP server: This option is attached to a tier-0 or tier-1 gateway and provides DHCP service to the networks (overlay segments) that are directly connected to the gateway and configured to use a gateway DHCP server.
DHCP Relay: This option relays the DHCP client requests to the external DHCP servers that can be in any subnet, outside the SDDC, or in the physical network.

NEW QUESTION 11
An NSX administrator would like to export syslog events that capture messages related to NSX host preparation events. Which message ID (msgld) should be used in the syslog export configuration command as a filler?

• A. MONISTORING
• B. SYSTEM
• C. GROUPING
• D. FABRIC

Answer: D

Explanation:
According to the VMware NSX Documentation2, the FABRIC message ID (msgld) captures messages related to NSX host preparation events, such as installation, upgrade, or uninstallation of NSX components on ESXi hosts. The syslog export configuration command for NSX host preparation events would look something like this:
set service syslog export FABRIC
The other options are either incorrect or not relevant for NSX host preparation events. MONITORING captures messages related to NSX monitoring features, such as alarms and system events2. SYSTEM captures messages related to NSX system events, such as login, logout, or configuration changes2. GROUPING captures messages related to NSX grouping objects, such as security groups, security tags, or IP sets2.

• B. From the NSX UI the status of the VMware Identity Manager Integration must be "Enabled".
• C. From the NSX CLI the status of the VMware Identity Manager Integration must be "Configured".
• D. From the NSX UI the URI in the address bar must have "locaNfatse" part of it.

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.

NEW QUESTION 16
An NSX administrator is using ping to check connectivity between VM1 running on ESXi1 to VM2 running on ESXi2. The ping tests fails. The administrator knows the maximum transmission unit size on the physical switch is 1600.
Which command does the administrator use to check the VMware kernel ports for tunnel end point communication?

• A. esxcli network diag ping -I vmk0O -H <destination IP address>
• B. vmkping ++netstack=geneve -d -s 1572 <destination IP address>
• C. esxcli network diag ping -H <destination IP address>
• D. vmkping ++netstack=vxlan -d -s 1572 <destination IP address>

Answer: B

Explanation:
The command vmkping ++netstack=geneve -d -s 1572 <destination IP address> is used to check the VMwar kernel ports for tunnel end point communication. This command uses the geneve netstack, which is the default netstack for NSX-T. The -d option sets the DF (Don’t Fragment) bit in the IP header, which prevents the packet from being fragmented by intermediate routers. The -s 1572 option sets the packet size to 1572 bytes, which is the maximum payload size for a geneve encapsulated packet with an MTU of 1600 bytes.
The <destination IP address> is the IP address of the remote ESXi host or VM. References: : VMware NS Data Center Installation Guide, page 19. : VMware Knowledge Base: Testing MTU with the vmkping command (1003728). : VMware NSX-T Data Center Administration Guide, page 102.
