Which command is used to display the network configuration of the Tunnel Endpoint (TEP) IP on a bare metal transport node?
Correct Answer:
B
The command ifconfig is used to display the network configuration of the Tunnel Endpoint (TEP) IP on a ba metal transport node2. The TEP IP is assigned to a network interface on the bare metal server that is used for overlay traffic. The ifconfig command can show the IP address, netmask, broadcast address, and other information of the network interface. For example, the following command shows the network configuration
of the TEP IP on a bare metal transport node with interface name ens192:
ifconfig ens192
The output of the command would look something like this:
ens192: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.10.10.10 netmask 255.255.255.1 broadcast 10.10.10.255 inet6 fe80::250:56ff:fe9a:1b8c prefixlen 64 scopeid 0x20<link> ether 00:50:56:9a:1b:8c txqueuelen 1000 (Ethernet) RX packets 123456 bytes 123456789 (123.4 MB) RX errors 0
dropped 0 overruns 0 frame 0 TX packets 234567 bytes 234567890 (234.5 MB) TX errors 0 dropped 0
overruns 0 carrier 0 collisions 0
The TEP IP in this example is 10.10.10.10. References:

What are two valid options when configuring the scope of a distributed firewall rule? (Choose two.)
Correct Answer:
CE
* C. Segment. This is correct. A segment is a logical construct that represents a layer 2 broadcast domain and a layer 3 subnet in NSX. A segment can be used to group and connect virtual machines, containers, or bare metal hosts that belong to the same application or service. A segment can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that enters or exits the segment12
* E. Group. This is correct. A group is a logical construct that represents a collection of objects in NSX, such as segments, segment ports, virtual machines, IP addresses, MAC addresses, tags, or security policies. A group can be used to define dynamic membership criteria based on various attributes or filters. A group can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that matches the group membership criteria32
When deploying an NSX Edge Transport Node, what two valid IP address assignment options should be specified for the TEP IP addresses? (Choose two.)
Correct Answer:
AD
When deploying an NSX Edge Transport Node, two valid IP address assignment options that should be specified for the TEP IP addresses are Use an IP Pool and Use a Static IP List. These options allow the u assign TEP IP addresses from a predefined range of IP addresses or a manually entered list of IP addresses, respectively345. The other options are incorrect because they are not supported methods for assigning TEP IP addresses. There is no option to use a DHCP server, RADIUS, or BootP for TEP IP address assignment in NSX-T345.

How does the Traceflow tool identify issues in a network?
Correct Answer:
D
The Traceflow tool identifies issues in a network by injecting synthetic traffic into the data plane and observing the results in the control plane. This allows the tool to identify any issues in the network and provide a detailed report on the problem. You can use the Traceflow tool to test connectivity between any two endpoints in your NSX-T Data Center environment.
Which Is the only supported mode In NSX Global Manager when using Federation?
Correct Answer:
B
NSX Global Manager is a feature of NSX that allows managing multiple NSX domains across different sites or clouds from a single pane of glass. NSX Global Manager supports Federation, which is a capability that enables synchronizing configuration and policy across multiple NSX domains. Federation has many benefits such as simplifying operations, improving resiliency, and enabling disaster recovery.
The only supported mode in NSX Global Manager when using Federation is Policy mode. Policy mode means that NSX Global Manager acts as a policy manager that defines and distributes global policies to local NSX managers in different domains. Policy mode also allows local NSX managers to have their own local policies that can override or merge with global policies.
