What can the administrator use to identify overlay segments in an NSX environment if troubleshooting is required?

1. A. VNI ID
2. B. Segment ID
3. C. Geneve ID
4. D. VIAN ID

Correct Answer: A
According to the VMware NSX Documentation1, a segment is mapped to a unique Geneve segment that is distributed across the ESXi hosts in a transport zone. The Geneve segment uses a virtual network identifier (VNI) as an overlay network identifier. The VNI ID can be used to identify overlay segments in an NSX environment if troubleshooting is required.

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

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

Correct Answer: D
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 .

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?

1. A. MONISTORING
2. B. SYSTEM
3. C. GROUPING
4. D. FABRIC

Correct Answer: D
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.

An NSX administrator has deployed a single NSX Manager node and will be adding two additional nodes to form a 3-node NSX Management Cluster for a production environment. The administrator will deploy these two additional nodes and Cluster VIP using the NSX UI.
What two are the prerequisites for this configuration? (Choose two.)

1. A. All nodes must be in separate subnets.
2. B. The cluster configuration must be completed using API.
3. C. NSX Manager must reside on a Windows Server.
4. D. All nodes must be in the same subnet.
5. E. A compute manager must be configured.

Correct Answer: DE
According to the VMware NSX Documentation, these are the prerequisites for adding nodes to an NSX Management Cluster using the NSX UI:
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.
