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.
Correct Answer: A
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 uide, 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
Question 82:
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
B. vmkping ++netstack=geneve-d-s 1572
C. esxcli network diag ping-H
D. vmkping ++netstack=vxlan-d-s 1572
Correct Answer: B
The command vmkping ++netstack=geneve-d-s 1572 is used to check the VMware 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 is the IP address of the remote ESXi host or VM.

Question 83:
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
Correct Answer: D
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 a 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.

Question 84:
What are two supported host switch modes? (Choose two.)
A. DPDK Datapath
B. Enhanced Datapath
C. Overlay Datapath
D. Secure Datapath
E. Standard Datapath
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
Question 85:
Which statement is true about an alarm in a Suppressed state?
A. An alarm can be suppressed for a specific duration in seconds.
B. An alarm can be suppressed for a specific duration in days.
C. An alarm can be suppressed for a specific duration in minutes.
D. An alarm can be suppressed for a specific duration in hours.
Correct Answer: D
An alarm can be suppressed for a specific duration in hours. According to the VMware NSX documentation, an alarm can be in one of the following states: Open, Acknowledged, Suppressed, or Resolved12 An alarm in a Suppressed state means that the status reporting for this alarm has been disabled by the user for a user-specified duration12 When a user moves an alarm into a Suppressed state, they are prompted to specify the duration in hours. After the specified duration passes, the alarm state reverts to Open. However, if the system determines the condition has been corrected, the alarm state changes to Resolved13 To learn more about how to manage alarm states in NSX, you can refer to the following resources: VMware NSX Documentation: Managing Alarm States 1 VMware NSX Documentation: View Alarm Information 2 VMware NSX Intelligence Documentation: Manage NSX Intelligence Alarm States https://docs.vmware.com/en/VMware-NSXIntelligence/1.2/user-guide/GUID-EBD3C5A8-F9AB-4A22-BA40-92D61850C1E6.html
Question 86:
An administrator has been tasked with implementing the SSL certificates for the NSX Manager Cluster VIP.
Which is the correct way to implement this change?
A. Send an API call to https:///api/v1/cluster/api-certificate? action=set_cluster_certificateandcertificate_id=
B. Send an API call to https:///api/v1/node/services/http? action=apply_certificateandcertificate_id=
C. SSH as admin into the NSX manager with the cluster VIP IP and run nsxcli cluster certificate vip install
D. SSH as admin into the NSX manager with the cluster VIP IP and run nsxcli cluster certificate node install
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
Correct Answer: B
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.

Question 89:
What must be configured on Transport Nodes for encapsulation and decapsulation of Geneve protocol?
A. VXIAN
B. UDP
C. STT
D. TEP
Correct Answer: D
According to the VMware NSX Documentation, TEP stands for Tunnel End Point and is a logical interface that must be configured on transport nodes for encapsulation and decapsulation of Geneve protocol. Geneve is a tunneling protocol that encapsulates the original packet with an outer header that contains metadata such as the virtual network identifier (VNI) and the transport node IP address. TEPs are responsible for adding and removing the Geneve header as the packet traverses the overlay network.
