NEW QUESTION # 13
Which two built-in VMware tools will help Identify the cause of packet loss on VLAN Segments? (Choose two.)
- A. Flow Monitoring
- B. Packet Capture
- C. Activity Monitoring
- D. Live Flow
- E. Traceflow
Answer: B,E
Explanation:
Explanation
According to the VMware NSX Documentation1, Packet Capture and Traceflow are two built-in VMware tools that can help identify the cause of packet loss on VLAN segments.
Packet Capture allows you to capture packets on a specific interface or segment and analyze them using tools such as Wireshark or tcpdump. Packet Capture can help you diagnose network issues such as misconfigured MTU, incorrect VLAN tags, or firewall drops.
Traceflow allows you to inject synthetic packets into the network and trace their path from source to destination. Traceflow can help you verify connectivity, routing, and firewall rules between virtual machines or segments. Traceflow can also show you where packets are dropped or modified along the way.
NEW QUESTION # 14
Which TraceFlow traffic type should an NSX administrator use tor validating connectivity between App and DB virtual machines that reside on different segments?
- A. Broadcast
- B. Unicast
- C. Multicast
- D. Anycast
Answer: B
Explanation:
Explanation
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.

Which of the two following characteristics about NAT64 are true? (Choose two.)
- A. NAT64 requires the Tier-1 gateway to be configured in active-active mode.
- B. NAT64 is supported on Tier-0 and Tier-1 gateways.
- C. NAT64 requires the Tier-1 gateway to be configured in active-standby mode.
- D. NAT64 is stateless and requires gateways to be deployed in active-standby mode.
- E. NAT64 is supported on Tier-1 gateways only.
Answer: A,B
Explanation:
Explanation
NAT64 is a type of NAT that allows IPv6-only hosts to communicate with IPv4-only hosts by translating the IPv6 addresses to IPv4 addresses and vice versa.
C: NAT64 is supported on Tier-0 and Tier-1 gateways. This is stated in the first result1, which says
"Three types of NAT are supported, in addition to NAT64."
E: NAT64 requires the Tier-1 gateway to be configured in active-active mode. This is implied by the third result2, which says "Stateful NAT is not supported in active-active mode." Since NAT64 is stateless, it can be supported in active-active mode.
NEW QUESTION # 18
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 a PowerCU script
- B. Use the CU on each Edge Node
- C. Use a Node Profile
- D. Use Transport Node Profile
Answer: D
Explanation:
Explanation
Transport Node Profile is a feature of NSX that allows an administrator to apply a common configuration to multiple transport nodes, such as Edge nodes or host clusters. A Transport Node Profile can include settings such as NTP server, transport zone, IP pool, uplink profile, and LLDP profile. By using a Transport Node Profile, an administrator can efficiently add an NTP server to all 10 Edge Transport Nodes without having to configure each node individually .
NEW QUESTION # 19
When a stateful service is enabled for the first lime on a Tier-0 Gateway, what happens on the NSX Edge node'
- A. SR is instantiated and automatically connected with DR.
- B. DR Is instantiated and automatically connected with SR.
- C. SR and DR Is instantiated but requites manual connection.
- D. SR and DR doesn't need to be connected to provide any stateful services.
Answer: A
Explanation:
Explanation
The answer is A. SR is instantiated and automatically connected with DR.
SR stands for Service Router and DR stands for Distributed Router. They are components of the NSX Edge node that provide different functions1 The SR is responsible for providing stateful services such as NAT, firewall, load balancing, VPN, and DHCP.
The DR is responsible for providing distributed routing and switching between logical segments and the physical network1 When a stateful service is enabled for the first time on a Tier-0 Gateway, the NSX Edge node automatically creates an SR instance and connects it with the existing DR instance. This allows the stateful service to be applied to the traffic that passes through the SR before reaching the DR2 According to the VMware NSX 4.x Professional Exam Guide, understanding the SR and DR components and their functions is one of the exam objectives3 To learn more about the SR and DR components and how they work on the NSX Edge node, you can refer to the following resources:
* VMware NSX Documentation: NSX Edge Components 1
* VMware NSX 4.x Professional: NSX Edge Architecture
* VMware NSX 4.x Professional: NSX Edge Routing

- B. esxcfg-vmknic -1l
- C. esxcfg-nics -1l
- D. esxcli network ip interface ipv4 get
- E. net-dvs
Answer: B,D
Explanation:
Explanation
To check the IP address of the VMkernel port for the Geneve protocol on the ESXi transport node, an NSX administrator can use the following commands:
esxcli network ip interface ipv4 get: This command displays the IPv4 configuration of all VMkernel interfaces on the host, including their IP addresses, netmasks, and gateways. The Geneve protocol uses a VMkernel interface named geneve0 by default1 esxcfg-vmknic -l: This command lists all VMkernel interfaces on the host, along with their MAC addresses, MTU, and netstack. The Geneve protocol uses a netstack named nsx-overlay by default

What are two supported host switch modes? (Choose two.)
- A. Enhanced Datapath
- B. Standard Datapath
- C. Overlay Datapath
- D. Secure Datapath
- E. DPDK Datapath
Answer: A,B
Explanation:
Explanation
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

- A. Keyoen Enterprise
- B. RSA SecurelD
- C. LDAP and OpenLDAP based on Active Directory (AD)
- D. RADII 2.0
- E. SecureDAP
Answer: B,C
Explanation:
NSX supports two types of authentication, authorization, and accounting (AAA) systems when integrating with VMware Identity Manager: RSA SecurID and LDAP and OpenLDAP based on Active Directory (AD). RSA SecurID is a two-factor authentication system that uses a token-based approach to verify the identity of users. LDAP and OpenLDAP based on AD are directory services that store and manage user information and credentials. Both systems can be used to provide centralized authentication for users who want to access applications in an NSX environment .
NEW QUESTION # 24
What are three NSX Manager rotes? (Choose three.)
- A. master
- B. zookeepet
- C. cloud
- D. policy
- E. manager
- F. controller
Answer: D,E,F
Explanation:
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.
NEW QUESTION # 25
A customer has a network where BGP has been enabled and the BGP neighbor is configured on the Tier-0 Gateway. An NSX administrator used the get gateways command to retrieve this Information:
Which two commands must be executed to check BGP neighbor status? (Choose two.)
- A. vrf 1
- B. sa-nexedge-01(tier0_sr> get bgp neighbor
- C. vrf 4
- D. vrf 3
- E. sa-nexedge-01(tier1_sr> get bgp neighbor
- F. sa-nexedge-01(tier1_dr)> get bgp neighbor
Answer: B,C
Explanation:
Explanation
According to the image that you sent, the BGP neighbor is configured on the tier-0 gateway with the UUID
9f8e3a7c-5f9c-4d1a-bb6f-9c7f3d6f3d63 and the VRF ID 4. Therefore, to check the BGP neighbor status, you need to enter the VRF context of 4 and execute the get bgp neighbor command on the tier-0 service router (SR) node.
The other options are either incorrect or not applicable for this scenario. vrf 1, vrf 3, and sa-nexedge-01(tier1_dr)> get bgp neighbor are not related to the BGP neighbor configuration on the tier-0 gateway. sa-nexedge-01(tier1_sr> get bgp neighbor is also not relevant, as there is no BGP neighbor configured on the tier-1 gateway.
