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
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

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:

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.
Answer: 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.
To learn more about tags membership and how to use it for micro-segmentation in NSX, you can refer to
the following resources:

5.When collecting support bundles through NSX Manager, which files should be excluded for potentially
containing sensitive information?
A. Controller Files
B. Management Files
C. Core Files
D. Audit Files
Answer: C
Explanation:
According to the VMware NSX Documentation1, core files and audit logs can contain sensitive
information and should be excluded from the support bundle unless requested by VMware technical
support. Controller files and management files are not mentioned as containing sensitive information.
Reference: 1: Support Bundle Collection Tool - VMware Docs
Core files and Audit logs might contain sensitive information such as passwords or encryption keys.

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.
5/8
Download 2V0-41.24 exam dumps for best preparation
E. BGP is enabled by default.
Answer: 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:
VMware NSX Documentation: Configure BGP 1

The main components on the edge node for north-south malware prevention perform the following
functions:
• IDS/IPS engine: Extracts files and relays events and data to the security hub
North-south malware prevention uses the file extraction features of the IDS/IPS engine that runs on NSX
Edge for north-south traffic.

• Security hub: Collects file events, obtains verdicts for known files, sends files for local and cloud-based
analysis, and sends information to the security analyzer
• RAPID: Provides local analysis of the file
• ASDS Cache: Caches reputation and verdicts of known files
8.Which two statements are true about IDS Signatures? (Choose two.)
A. Users can upload their own IDS signature definitions.
B. An IDS signature contains data used to identify known exploits and vulnerabilities.
C. An IDS signature contains data used to identify the creator of known exploits and vulnerabilities.
D. IDS signatures can be High Risk, Suspicious, Low Risk and Trustworthy.
E. An IDS signature contains a set of instructions that determine which traffic is analyzed.
Answer: BE
Explanation:
According to the Network Bachelor article1, an IDS signature contains data used to identify an attacker’s
attempt to exploit a known vulnerability in both the operating system and applications. This implies that
statement B is true. According to the VMware NSX Documentation2, IDS/IPS Profiles are used to group
signatures, which can then be applied to select applications and traffic. This implies that statement E is
true. Statement A is false because users cannot upload their own IDS signature definitions, they have to
use the ones provided by VMware or Trustwave3. Statement C is false because an IDS signature does
not contain data used to identify the creator of known exploits and vulnerabilities, only the exploits and
vulnerabilities themselves. Statement D is false because IDS signatures are classified into one of the
following severity categories: Critical, High, Medium, Low, or Informational1.

9.Which NSX CLI command is used to change the authentication policy for local users?
A. Set cli-timeout
B. Get auth-policy minimum-password-length
C. Set hardening- policy
D. Set auth-policy
Answer: D
Explanation:
According to the VMware NSX Documentation4, the set auth-policy command is used to change the
authentication policy settings for local users, such as password length, lockout period, and maximum
authentication failures. The other commands are either used to view the authentication policy settings (B),
change the CLI session timeout (A), or change the hardening policy settings ©.

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.
Answer: 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

11.How is the RouterLink port created between a Tier-1 Gateway and Tler-0 Gateway?
A. Manually create a Logical Switch and connect to bother Tler-1 and Tier-0 Gateways.
B. Automatically created when Tler-1 is created.
C. Manually create a Segment and connect to both Titrr-1 and Tier-0 Gateways.
D. Automatically created when Tier-t Is connected with Tier-0 from NSX UI.
Answer: D
Explanation:
According to the VMware NSX 4.x Professional documents and tutorials, a RouterLink port is a logical
port that connects a Tier-1 gateway to a Tier-0 gateway. This port is automatically created when a Tier-1
gateway is associated with a Tier-0 gateway from the NSX UI or API. The RouterLink port enables routing
between the two gateways and carries all the routing protocols and traffic. There is no need to manually
create a logical switch or segment for this purpose1.
