NEW QUESTION 1
A customer is preparing to deploy a VMware Kubernetes solution in an NSX environment. What is the minimum MTU size for the UPLINK profile?

• A. 1500
• B. 1550
• C. 1700
• D. 1650

Answer: C

Explanation:
The minimum MTU size for the UPLINK profile is 1700 bytes. This is because the UPLINK profile is used to configure the physical NICs that connect to the NSX-T overlay network. The overlay network uses geneve encapsulation, which adds an overhead of 54 bytes to the original packet. Therefore, to support a standard MTU of 1500 bytes for the inner packet, the outer packet must have an MTU of at least 1554 bytes. However, VMware recommends adding an extra buffer of 146 bytes to account for possible additional headers or VLAN tags. Therefore, the minimum MTU size for the UPLINK profile is 1700 bytes (1554 + 146).

NEW QUESTION 2
Which of the following settings must be configured in an NSX environment before enabling stateful active-active SNAT?

• A. Tier-1 gateway in active-standby mode
• B. Tier-1 gateway in distributed only mode
• C. An Interface Group for the NSX Edge uplinks
• D. A Punting Traffic Group for the NSX Edge uplinks

Answer: C

Explanation:
To enable stateful active-active SNAT on a Tier-0 or Tier-1 gateway, you must configure an Interface Group for the NSX Edge uplinks. An Interface Group is a logical grouping of NSX Edge interfaces that belong to the same failure domain. A failure domain is a set of NSX Edge nodes that share the same physical network infrastructure and are subject to the same network failures. By configuring an Interface Group, you can ensure that the stateful services are distributed across different failure domains and can recover from network failures1

NEW QUESTION 3
What must be configured on Transport Nodes for encapsulation and decapsulation of Geneve protocol?

• A. VXIAN
• B. UDP
• C. STT
• D. TEP

Answer: D

Explanation:
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.

NEW QUESTION 10
Which two statements describe the characteristics of an Edge Cluster in NSX? (Choose two.)

• A. Can have a maximum of 8 edge nodes
• B. Can have a maximum of 10 edge nodes
• C. Must have only active-active edge nodes
• D. Can contain multiple types of edge nodes (VM or bare metal)
• E. Must contain only one type of edge nodes (VM or bare metal)

Answer: AE

Explanation:
Two statements that describe the characteristics of an Edge Cluster in NSX are:
An Edge Cluster can have a maximum of 8 edge nodes2. This is the upper limit for scaling out the Edge Cluster and providing high availability and load balancing for network services.
An Edge Cluster must contain only one type of edge nodes (VM or bare metal)3. This is because different types of edge nodes have different performance and resource requirements, and mixing them in the same cluster can cause inconsistency and instability. The other options are incorrect because they do not describe the characteristics of an Edge Cluster in NSX. An Edge Cluster can have either
active-active or active-standby edge nodes, depending on the configuration and services4. An Edge Cluster cannot contain multiple types of edge nodes, as explained above.

NEW QUESTION 11
NSX improves the security of today's modern workloads by preventing lateral movement, which feature of NSX can be used to achieve this?

• A. Network Segmentation
• B. Virtual Security Zones
• C. Edge Firewalling
• D. Dynamic Routing

Answer: A

Explanation:
According to the web search results, network segmentation is a feature of NSX that improves the security of today’s modern workloads by preventing lateral movement. Lateral movement is a technique used by attackers to move from one compromised system to another within a network, exploiting vulnerabilities or credentials . Network segmentation prevents lateral movement by dividing a network into smaller segments or zones, each with its own security policies and controls. This way, if one segment is compromised, the attacker cannot access other segments or resources . NSX enables network segmentation by using micro-segmentation, which applies granular firewall rules at the virtual machine level, regardless of the physical network topology .

NEW QUESTION 12
Which troubleshooting step will resolve an error with code 1001 during the configuration of a time-based firewall rule?

• A. Reinstalling the NSX VIBs on the ESXi host.
• B. Restarting the NTPservice on the ESXi host.
• C. Changing the lime zone on the ESXi host.
• D. Reconfiguring the ESXI host with a local NTP server.

Answer: B

Explanation:
According to the web search results, error code 1001 is related to a time synchronization issue between the ESXi host and the NSX Manager. This can cause problems when configuring a time-based firewall rule, which requires the ESXi host and the NSX Manager to have the same time zone and NTP server settings . To resolve this error, you need to restart the NTP service on the ESXi host to synchronize the time with the NSX Manager. You can use the following command to restart the NTP service on the ESXi host:
/etc/init.d/ntpd restart
The other options are not valid solutions for this error. Reinstalling the NSX VIBs on the ESXi host will not fix the time synchronization issue. Changing the time zone on the ESXi host may cause more discrepancies with the NSX Manager. Reconfiguring the ESXi host with a local NTP server may not be compatible with the NSX Manager’s NTP server.

NEW QUESTION 13
Which is an advantages of a L2 VPN In an NSX 4.x environment?

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

Answer: D

Explanation:
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 .

NEW QUESTION 14
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:
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

NEW QUESTION 15
Where is the insertion point for East-West network introspection?

• A. Tier-0 router
• B. Partner SVM
• C. Guest VM vNIC
• D. Host Physical NIC

Answer: C

Explanation:
The insertion point for East-West network introspection is the Guest VM vNIC. Network introspection is a service insertion feature that allows third-party network services to be integrated with NSX. Network introspection enables traffic redirection from the Guest VM vNIC to a service virtual machine (SVM) that runs the partner service. The SVM can then inspect, monitor, or modify the traffic before sending it back to the original destination1. The other options are incorrect because they are not the insertion points for East-West network introspection. The Tier-0 router is used for North-South routing and network services. The partner SVM is the service virtual machine that runs the partner service, not the insertion point. The host physical NIC is not involved in network introspection.

NEW QUESTION 18
Refer to the exhibit.
An administrator would like to change the private IP address of the NAT VM I72.l6.101.il to a public address of 80.80.80.1 as the packets leave the NAT-Segment network.
Which type of NAT solution should be implemented to achieve this?

• A. DNAT
• B. SNAT
• C. Reflexive NAT
• D. NAT64

Answer: B

Explanation:
SNAT stands for Source Network Address Translation. It is a type of NAT that translates the source IP address of outgoing packets from a private address to a public address. SNAT is used to allow hosts in a private network to access the internet or other public networks1
In the exhibit, the administrator wants to change the private IP address of the NAT VM 172.16.101.11 to a public address of 80.80.80.1 as the packets leave the NAT-Segment network. This is an example of SNAT, as the source IP address is modified before the packets are sent to an external network.
According to the VMware NSX 4.x Professional Exam Guide, SNAT is one of the topics covered in the exam objectives2
To learn more about SNAT and how to configure it in VMware NSX, you can refer to the following resources: VMware NSX Documentation: NAT 3

NEW QUESTION 19
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

Answer: D

Explanation:
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 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. References: Gateway Firewall
