質問 # 19
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. Do a service insertion to accomplish the task.
- B. Group all by means of tags membership.
- C. Create an Ethernet based security policy.
- D. Use Edge as a firewall between tiers.
正解：B
解説：
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:

質問 # 22
Which three of the following describe the Border Gateway Routing Protocol (BGP) configuration on a Tier-0 Gateway? (Choose three.)
- A. The network is divided into areas that are logical groups.
- B. It supports a 4-byte autonomous system number.
- C. Can be used as an Exterior Gateway Protocol.
- D. EIGRP Is disabled by default.
- E. BGP is enabled by default.
正解：B、C、D
解説：
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
VMware NSX 4.x Professional: BGP Configuration
VMware NSX 4.x Professional: BGP Troubleshooting
質問 # 23
A customer has a network where BGP has been enabled and the BGP neighbor is configured on the Tier-0 Gateway. An NSX administrator used the get gateways command to retrieve this Information:
Which two commands must be executed to check BGP neighbor status? (Choose two.)
- A. vrf 1
- B. vrf 4
- C. sa-nexedge-01(tier1_sr> get bgp neighbor
- D. sa-nexedge-01(tier0_sr> get bgp neighbor
- E. sa-nexedge-01(tier1_dr)> get bgp neighbor
- F. vrf 3
正解：B、D
解説：
Explanation
According to the image that you sent, the BGP neighbor is configured on the tier-0 gateway with the UUID
9f8e3a7c-5f9c-4d1a-bb6f-9c7f3d6f3d63 and the VRF ID 4. Therefore, to check the BGP neighbor status, you need to enter the VRF context of 4 and execute the get bgp neighbor command on the tier-0 service router (SR) node.
The other options are either incorrect or not applicable for this scenario. vrf 1, vrf 3, and sa-nexedge-01(tier1_dr)> get bgp neighbor are not related to the BGP neighbor configuration on the tier-0 gateway. sa-nexedge-01(tier1_sr> get bgp neighbor is also not relevant, as there is no BGP neighbor configured on the tier-1 gateway.
質問 # 24
Which command on ESXI is used to verify the Local Control Plane connectivity with Central Control Plane?
- A.
- B.
- C.
- D.
正解：C
解説：
Explanation
According to the web search results, the command that is used to verify the Local Control Plane (LCP) connectivity with Central Control Plane (CCP) on ESXi is get control-cluster status. This command displays the status of the LCP and CCP components on the ESXi host, such as the LCP agent, CCP client, CCP server, and CCP connection. It also shows the IP address and port number of the CCP server that the LCP agent is connected to. If the LCP agent or CCP client are not running or not connected, it means that there is a problem with the LCP connectivity .

正解：C、D
解説：
Explanation
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.
質問 # 26
Which two statements are true about IDS Signatures? (Choose two.)
- A. An IDS signature contains a set of instructions that determine which traffic is analyzed.
- B. IDS signatures can be High Risk, Suspicious, Low Risk and Trustworthy.
- C. An IDS signature contains data used to identify the creator of known exploits and vulnerabilities.
- D. An IDS signature contains data used to identify known exploits and vulnerabilities.
- E. Users can upload their own IDS signature definitions.
正解：A、D
解説：
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.

Which troubleshooting step will resolve an error with code 1001 during the configuration of a time-based firewall rule?
- A. Restarting the NTPservice on the ESXi host.
- B. Changing the lime zone on the ESXi host.
- C. Reinstalling the NSX VIBs on the ESXi host.
- D. Reconfiguring the ESXI host with a local NTP server.
正解：A
解説：
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.
質問 # 37
Which three NSX Edge components are used for North-South Malware Prevention? (Choose three.)
- A. Security Analyzer
- B. IDS/IPS
- C. RAPID
- D. Reputation Service
- E. Security Hub
- F. Thin Agent
正解：B、C、D
解説：
Explanation
B: RAPID. This is correct. RAPID stands for Real-time Anti-malware Protection with Intelligent Detection. It is a component of the NSX Edge node that provides malware prevention for the north-south traffic. RAPID extracts files from the network traffic and analyzes them for malicious behavior using hash-based detection, local analysis, and cloud analysis techniques1 D: IDS/IPS. This is correct. IDS/IPS stands for Intrusion Detection and Prevention System. It is a component of the NSX Edge node that provides intrusion detection and prevention for the north-south traffic. IDS/IPS monitors the network traffic and compares it against a known set of signatures that specify patterns for different types of network intrusions. IDS/IPS can generate alerts or block the traffic based on the matching signatures and the configured actions2 F: Reputation Service. This is correct. Reputation Service is a component of the NSX Edge node that provides reputation-based filtering for the north-south traffic. Reputation Service uses a cloud-based database of known malicious IP addresses and domains to block or allow the traffic based on the reputation score of the source or destination. Reputation Service can also integrate with third-party reputation providers to enhance the security coverage3 A: Thin Agent. This is incorrect. Thin Agent is not a component of the NSX Edge node, but rather a component of the NSX Guest Introspection platform that runs on the virtual machine endpoints in the distributed east-west traffic. Thin Agent enables communication between the virtual machines and the NSX Manager, and facilitates malware prevention and intrusion detection on the host level.
C: Security Hub. This is incorrect. Security Hub is not a component of the NSX Edge node, but rather a component of the VMware Cloud Services platform that provides a unified view of security posture across multiple cloud environments. Security Hub integrates with NSX Advanced Threat Prevention to collect and display security events, alerts, and recommendations from NSX IDS/IPS and NSX Malware Prevention features.
E: Security Analyzer. This is incorrect. Security Analyzer is not a real product name or component name related to NSX Edge or NSX Advanced Threat Prevention. It is a fictional name that does not exist in the VMware portfolio.
To learn more about NSX Edge components for North-South Malware Prevention, you can refer to the following resources:
VMware NSX Documentation: Overview of NSX IDS/IPS and NSX Malware Prevention 2 VMware NSX Documentation: Configure North-South Malware Prevention 1 VMware NSX Documentation: Configure North-South Intrusion Detection and Prevention VMware NSX Documentation: Configure North-South Reputation-Based Filtering 3
