Question 13:
Which two statements are true for IPSec VPN? (Choose two.)
A. VPNs can be configured on the command line Interface on the NSX manager.
B. IPSec VPN services can be configured at Tler-0 and Tler-1 gateways.
C. IPSec VPNs use the DPDK accelerated performance library.
D. Dynamic routing Is supported for any IPSec mode In NSX.
Correct Answer: BC
According to the VMware NSX 4.x Professional documents and tutorials, IPSec VPN secures traffic flowing between two networks connected over a public network through IPSec gateways called endpoints. NSX Edge supports a policy-based or a route-based IPSec VPN. Beginning with NSX-T Data Center 2.5, IPSec VPN services are supported on both Tier-0 and Tier-1 gateways1. NSX Edge also leverages the DPDK accelerated performance library to optimize the performance of IPSec VPN2. https://docs.vmware.com/en/VMware-NSX/4.0/administration/GUID-7D9F7199-E51B-478B-A8BC-58AD5BBAA0F6.html
Question 14:
Which three protocols could an NSX administrator use to transfer log messages to a remote log server? (Choose three.)
A. HTTPS
B. TCP
C. SSH
D. UDP
E. TLS
F. SSL
Correct Answer: BDE
An NSX administrator can use TCP, UDP, or TLS protocols to transfer log messages to a remote log server. These protocols are supported by NSX Manager, NSX Edge, and hypervisors for remote logging. A Log Insight log server supports all these protocols, as well as LI and LI-TLS, which are specific to Log Insight and optimize network usage. HTTPS, SSH, and SSL are not valid protocols for remote logging in NSX-T Data Center. References: : VMware NSX-T Data Center Administration Guide, page 102. : VMware Docs: Configure Remote Logging
Question 15:
An NSX administrator is troubleshooting a connectivity issue with virtual machines running on an FSXi transport node. Which feature in the NSX Ul shows the mapping between the virtual NIC and the host's physical adapter?
A. Port Mirroring
B. Switch Visualization
C. Activity Monitoring
D. IPFIX
Correct Answer: B
According to the VMware NSX Documentation, Switch Visualization is a feature in the NSX UI that shows the mapping between the virtual NIC and the host's physical adapter for virtual machines running on an ESXi transport node. You can use Switch Visualization to view details such as port ID, MAC address, VLAN ID, IP address, MTU, port state, port speed, port type, and port group for each virtual NIC and physical adapter.
How does the Traceflow tool identify issues in a network?
A. Compares the management plane configuration states containing control plane traffic and error reporting from transport node agents.
B. Compares intended network state in the control plane with Tunnel End Point (TEP) keepalives in the data plane.
C. Injects ICMP traffic into the data plane and observes the results in the control plane.
D. Injects synthetic traffic into the data plane and observes the results in the control plane.
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.
Question 17:
What is the VMware recommended way to deploy a virtual NSX Edge Node?
A. Through the OVF command line tool
B. Through the vSphere Web Client
C. Through automated or Interactive mode using an ISO
D. Through the NSXUI
Correct Answer: D
Through the NSX UI. According to the VMware NSX Documentation2, you can deploy NSX Edge nodes as virtual appliances through the NSX UI by clicking Add Edge Node and providing the required information. The other options are either outdated or not applicable for virtual NSX Edge nodes. https://docs.vmware.com/en/VMware-NSX/4.1/installation/GUID-E9A01C68-93E7-4140-B306-19CD6806199F.html
Question 18:
Which two statements describe the characteristics of an Edge Cluster in NSX? (Choose two.)
A. Can have a maximum of 10 edge nodes
B. Can have a maximum of 8 edge nodes
C. Can contain multiple types of edge nodes (VM or bare metal)
D. Must contain only one type of edge nodes (VM or bare metal)
What are two valid options when configuring the scope of a distributed firewall rule? (Choose two.)
A. DFW
B. Tier-1 Gateway
C. Segment
D. Segment Port
E. Group
Correct Answer: AE
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 Reference: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-41CC06DF-1CD4-4233-B43E-492A9A3AD5F6.html https://docs.vmware.com/en/VMware-NSX-Data-Center-for-vSphere/6.4/ com.vmware.nsx.admin.doc/GUID-D44C8923-992F-4695-B9C0-5CC271679D09.html
Question 20:
Which two commands does an NSX administrator use to check the IP address of the VMkernel port for the Geneve protocol on the ESXi transport node? (Choose two.)
A. esxcfg-nics-1l
B. esxcli network ip interface ipv4 get
C. esxcli network nic list
D. esxcfg-vmknic-1
E. net-dvs
Correct Answer: BD
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
