Question #1
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
Correct Answer: B
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

Question #3
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
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:

Question #4
A company Is deploying NSX micro-segmentation in their vSphere environment to secure a simple application composed of web. app, and database tiers.
The naming convention will be:
• WKS-WEB-SRV-XXX
• WKY-APP-SRR-XXX
• WKI-DB-SRR-XXX
What is the optimal way to group them to enforce security policies from NSX?
- A . Use Edge as a firewall between tiers.
- B . Do a service insertion to accomplish the task.
- C . Group all by means of tags membership.
- D . Create an Ethernet based security policy.
Correct Answer: C
C
Explanation:
The answer is C. Group all by means of tags membership.
Tags are metadata that can be applied to physical servers, virtual machines, logical ports, and logical segments in NSX. Tags can be used for dynamic security group membership, which allows for granular and flexible enforcement of security policies based on various criteria1
In the scenario, the company is deploying NSX micro-segmentation to secure a simple application composed of web, app, and database tiers.
The naming convention will be:
– WKS-WEB-SRV-XXX
– WKY-APP-SRR-XXX
– WKI-DB-SRR-XXX
The optimal way to group them to enforce security policies from NSX is to use tags membership. For
example, the company can create three tags: Web, App, and DB, and assign them to the corresponding VMs based on their names. Then, the company can create three security groups: Web-SG, App-SG, and DB-SG, and use the tags as the membership criteria. Finally, the company can create and apply security policies to the security groups based on the desired rules and actions2
Using tags membership has several advantages over the other options:
– It is more scalable and dynamic than using Edge as a firewall between tiers. Edge firewall is a centralized solution that can create bottlenecks and performance issues when handling large amounts of traffic3
– It is more simple and efficient than doing a service insertion to accomplish the task. Service insertion is a feature that allows for integrating third-party services with NSX, such as antivirus or intrusion prevention systems. Service insertion is not necessary for basic micro-segmentation and can introduce additional complexity and overhead.
– It is more flexible and granular than creating an Ethernet based security policy. Ethernet based security policy is a type of policy that uses MAC addresses as the source or destination criteria. Ethernet based security policy is limited by the scope of layer 2 domains and does not support logical constructs such as segments or groups.

Question #6
Which three of the following describe the Border Gateway Routing Protocol (BGP) configuration on a Tier-0 Gateway? (Choose three.)
- A . Can be used as an Exterior Gateway Protocol.
- B . It supports a 4-byte autonomous system number.
- C . The network is divided into areas that are logical groups.
- D . EIGRP Is disabled by default.
- E . BGP is enabled by default.
Correct Answer: ABD
ABD
Explanation:
A) Can be used as an Exterior Gateway Protocol. This is correct. BGP is a protocol that can be used to exchange routing information between different autonomous systems (AS). An AS is a network or a group of networks under a single administrative control. BGP can be used as an Exterior Gateway Protocol (EGP) to connect an AS to other ASes on the internet or other external networks1
B) It supports a 4-byte autonomous system number. This is correct. BGP supports both 2-byte and 4-byte AS numbers. A 2-byte AS number can range from 1 to 65535, while a 4-byte AS number can range from 65536 to 4294967295. NSX supports both 2-byte and 4-byte AS numbers for BGP configuration on a Tier-0 Gateway2
C) The network is divided into areas that are logical groups. This is incorrect. This statement describes OSPF, not BGP. OSPF is another routing protocol that operates within a single AS and divides the network into areas to reduce routing overhead and improve scalability. BGP does not use the concept of areas, but rather uses attributes, policies, and filters to control the routing decisions and traffic flow3
D) FIGRP Is disabled by default. This is correct. FIGRP stands for Fast Interior Gateway Routing Protocol, which is an enhanced version of IGRP, an obsolete routing protocol developed by Cisco. FIGRP is not supported by NSX and is disabled by default on a Tier-0 Gateway.
E) BGP is enabled by default. This is incorrect. BGP is not enabled by default on a Tier-0 Gateway. To enable BGP, you need to configure the local AS number and the BGP neighbors on the Tier-0 Gateway using the NSX Manager UI or API.
To learn more about BGP configuration on a Tier-0 Gateway in NSX, you can refer to the following resources:

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
D
Explanation:
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

Question #12
What are three NSX Manager roles? (Choose three.)
- A . master
- B . cloud
- C . zookeepet
- D . manager
- E . policy
- F . controller
Correct Answer: DEF
DEF
Explanation:
According to the VMware NSX 4.x Professional documents and tutorials, an NSX Manager is a standalone appliance that hosts the API services, the management plane, control plane, and policy management. The NSX Manager has three built-in roles: policy, manager, and controller2. The policy role handles the declarative configuration of the system and translates it into desired state for the manager role. The manager role receives and validates the configuration from the policy role and stores it in a distributed persistent database. The manager role also publishes the configuration to the central control plane. The controller role implements the central control plane that computes the network state based on the configuration and topology information3. The other roles (master, cloud, and zookeeper) are not valid NSX Manager roles.

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

Question #18
Which TraceFlow traffic type should an NSX administrator use tor validating connectivity between App and DB virtual machines that reside on different segments?
- A . Multicast
- B . Unicast
- C . Anycast
- D . Broadcast
Correct Answer: B
B
Explanation:
Unicast is the traffic type that an NSX administrator should use for validating connectivity between App and DB virtual machines that reside on different segments. According to the VMware documentation1, unicast traffic is the traffic type that is used to send a packet from one source to one destination. Unicast traffic is the most common type of traffic in a network, and it is used for applications such as web browsing, email, file transfer, and so on2. To perform a traceflow with unicast traffic, the NSX administrator needs to specify the source and destination IP addresses, and optionally the protocol and related parameters1. The traceflow will show the path of the packet across the network and any observations or errors along the way3. The other options are incorrect because they are not suitable for validating connectivity between two specific virtual machines. Multicast traffic is the traffic type that is used to send a packet from one source to multiple destinations simultaneously2. Multicast traffic is used for applications such as video streaming, online gaming, and group communication4. To perform a traceflow with multicast traffic, the NSX administrator needs to specify the source IP address and the destination multicast IP address1. Broadcast traffic is the traffic type that is used to send a packet from one source to all devices on the same subnet2. Broadcast traffic is used for applications such as ARP, DHCP, and network discovery. To perform a traceflow with broadcast traffic, the NSX administrator needs to specify the source IP address and the destination MAC address as FF:FF:FF:FF:FF:FF1. Anycast traffic is not a valid option, as it is not supported by NSX Traceflow. Anycast traffic is a traffic type that is used to send a packet from one source to the nearest or best destination among a group of devices that share the same IP address. Anycast traffic is used for applications such as DNS, CDN, and load balancing.

Question #31
DRAG DROP
Sort the rule processing steps of the Distributed Firewall. Order responses from left to right.
Correct Answer: The correct order of the rule processing steps of the Distributed Firewall is as follows:
– Packet arrives at vfilter connection table. If matching entry in the table, process the packet.
– If connection table has no match, compare the packet to the rule table.
– If the packet matches source, destination, service, profile and applied to fields, apply the action defined.
– If the rule table action is allow, create an entry in the connection table and forward the packet.
– If the rule table action is reject or deny, take that action.
This order is based on the description of how the Distributed Firewall works in the web search results1. The first step is to check if there is an existing connection entry for the packet in the vfilter connection table, which is a cache of flow entries for rules with an allow action. If there is a match, the packet is processed according to the connection entry. If there is no match, the packet is compared to the rule table, which contains all the security policy rules. The rules are evaluated from top to bottom until a match is found. The match criteria include source, destination, service, profile and applied to fields. The action defined by the matching rule is applied to the packet. The action can be allow, reject or deny. If the action is allow, a new connection entry is created for the packet and the packet is forwarded to its destination. If the action is reject or deny, the packet is dropped and an ICMP message or a TCP reset message is sent back to the source.

Question #39
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.
Correct Answer: B
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.

Question #40
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
Correct Answer: A
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.
