NEW QUESTION 1
A customer is preparing to deploy a VMware Kubernetes solution in an NSX environment. What is the minimum MTU size for the UPLINK profile?

• A. 1500
• B. 1550
• C. 1700
• D. 1650

Answer: C

Explanation:
The minimum MTU size for the UPLINK profile is 1700 bytes. This is because the UPLINK profile is used to configure the physical NICs that connect to the NSX-T overlay network. The overlay network uses geneve encapsulation, which adds an overhead of 54 bytes to the original packet. Therefore, to support a standard MTU of 1500 bytes for the inner packet, the outer packet must have an MTU of at least 1554 bytes. However, VMware recommends adding an extra buffer of 146 bytes to account for possible additional headers or VLAN tags. Therefore, the minimum MTU size for the UPLINK profile is 1700 bytes (1554 + 146).

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.

NEW QUESTION 3
An NSX administrator would like to create an L2 segment with the following requirements:
• L2 domain should not exist on the physical switches.
• East/West communication must be maximized as much as possible.
Which type of segment must the administrator choose?

• A. VLAN
• B. Overlay
• C. Bridge
• D. Hybrid

Answer: B

Explanation:
An overlay segment is a layer 2 broadcast domain that is implemented as a logical construct in the NSX-T Data Center software. Overlay segments do not require any configuration on the physical switches, and they allow for optimal east/west communication between workloads on different ESXi hosts. Overlay segments use the Geneve protocol to encapsulate and decapsulate traffic between the hosts. Overlay segments are created and managed by the NSX Manager.

NEW QUESTION 4
Which is an advantages of a L2 VPN In an NSX 4.x environment?

• A. Enables Multi-Cloud solutions
• B. Achieve better performance
• C. Enables VM mobility with re-IP
• D. Use the same broadcast domain

Answer: D

Explanation:
L2 VPN is a feature of NSX that allows extending Layer 2 networks across different sites or clouds over an IPsec tunnel. L2 VPN has an advantage of enabling VM mobility with re-IP, which means that VMs can be moved from one site to another without changing their IP addresses or network configurations. This is possible because L2 VPN allows both sites to use the same broadcast domain, which means that they share the same subnet and VLAN .

NEW QUESTION 6
An NSX administrator is creating a Tier-1 Gateway configured In Active-Standby High Availability Mode. In the event of node failure, the failover policy should not allow the original tailed node to become the Active node upon recovery.
Which failover policy meets this requirement?

• A. Non-Preemptive
• B. Preemptive
• C. Enable Preemptive
• D. Disable Preemptive

Answer: A

Explanation:
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.

NEW QUESTION 7
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 8
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.

NEW QUESTION 9
Which two statements are true about IDS Signatures? (Choose two.)

• A. Users can upload their own IDS signature definitions.
• B. An IDS signature contains data used to identify known exploits and vulnerabilities.
• C. An IDS signature contains data used to identify the creator of known exploits and vulnerabilities.
• D. IDS signatures can be High Risk, Suspicious, Low Risk and Trustworthy.
• E. An IDS signature contains a set of instructions that determine which traffic is analyzed.

Answer: BE

Explanation:
According to the Network Bachelor article1, an IDS signature contains data used to identify an attacker’s attempt to exploit a known vulnerability in both the operating system and applications. This implies that statement B is true. According to the VMware NSX Documentation2, IDS/IPS Profiles are used to group signatures, which can then be applied to select applications and traffic. This implies that statement E is
true. Statement A is false because users cannot upload their own IDS signature definitions, they have to use the ones provided by VMware or Trustwave3. Statement C is false because an IDS signature does not contain data used to identify the creator of known exploits and vulnerabilities, only the exploits and vulnerabilities themselves. Statement D is false because IDS signatures are classified into one of the following severity categories: Critical, High, Medium, Low, or Informational1.

NEW QUESTION 10
Which CLI command is used for packet capture on the ESXi Node?

• A. tcpdump
• B. debug
• C. pktcap-uw
• D. set capture

Answer: C

Explanation:
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.

NEW QUESTION 11
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 13
Which field in a Tier-1 Gateway Firewall would be used to allow access for a collection of trustworthy web sites?

• A. Source
• B. Profiles -> Context Profiles
• C. Destination
• D. Profiles -> L7 Access Profile

Answer: D

Explanation:
The field in a Tier-1 Gateway Firewall that would be used to allow access for a collection of trustworthy web sites is Profiles -> L7 Access Profile. This field allows the user to create a Layer 7 access profile that defines list of allowed or blocked URLs based on categories, reputation, or custom entries1. The user can then apply the L7 access profile to a firewall rule to control the traffic based on the URL filtering criteria1. The other options are incorrect because they are not related to URL filtering. The Source field specifies the source IP address or group of the firewall rule1. The Destination field specifies the destination IP address or group of the firewall rule1. The Profiles -> Context Profiles field allows the user to create a context profile that defines a list of application signatures or attributes that can be used to identify and classify network
traffic1. References: Gateway Firewall

NEW QUESTION 14
Which two CLI commands could be used to see if vmnic link status is down? (Choose two.)

• A. esxcfg-nics -1
• B. excli network nic list
• C. esxcli network vswitch dvs wmare list
• D. esxcfg-vmknic -1
• E. esxcfg-vmsvc/get.network

Answer: AB

Explanation:
esxcfg-nics -l and esxcli network nic list are two CLI commands that can be used to see the vmnic link status on an ESXi host. Both commands display information such as the vmnic name, driver, link state, speed, and duplex mode. The link state can be either Up or Down, indicating whether the vmnic is connected or not. For example, the output of esxcfg-nics -l can look like this:

NEW QUESTION 15
Which CLI command on NSX Manager and NSX Edge is used to change NTP settings?

• A. get timezone
• B. get time-server
• C. set timezone
• D. set ntp-server

Answer: D

Explanation:
The CLI command on NSX Manager and NSX Edge that is used to change NTP settings is set ntp-server. Th command allows the user to configure one or more NTP servers for time synchronization12. The other options are incorrect because they are not valid CLI commands for changing NTP settings. The get timezone and timezone commands are used to display and configure the timezone of the system1. The get
time-server command is used to display the current time server configuration1. There are no CLI commands for using RADIUS or BootP for NTP settings. References: NSX-T Command-Line Interface
