  A. esxcfg-nics-1

  B. excli network nic list

  C. esxcli network vswitch dvs wmare list

  D. esxcfg-vmknic-1

  E. esxcfg-vmsvc/get.network

  Correct Answer: AB

  esxcfg-nics-l and esxcli network nic list are two CLI commands that can be used to see the vmnic link status on an ESXi host. Both commands display information such as the vmnic name, driver, link state, speed, and duplex mode. The link state can be either Up or Down, indicating whether the vmnic is connected or not. For example, the output of esxcfg-nics-l can look like this: Name PCI Driver Link Speed Duplex MAC Address MTU Description vmnic0 0000:02:00.0 igbn Up 1000Mbps Full 00:50:56:01:2a:3b 1500 Intel Corporation I350 Gigabit Network Connection vmnic1 0000:02:00.1 igbn Down 0Mbps Half 00:50:56:01:2a:3c 1500 Intel Corporation I350 Gigabit Network Connection

• Question 73:

  An NSX administrator Is treating a NAT rule on a Tler-0 Gateway configured In active-standby high availability mode. Which two NAT rule types are supported for this configuration? (Choose two.)

  A. Reflexive NAT

  B. Destination NAT

  C. 1:1 NAT

  D. Port NAT

  E. Source NAT

  Correct Answer: BE

  According to the VMware NSX Documentation, these are two NAT rule types that are supported for a tier-0 gateway configured in active-standby high availability mode. NAT stands for Network Address Translation and is a feature that allows

  you to modify the source or destination IP address of a packet as it passes through a gateway. Destination NAT: This rule type allows you to change the destination IP address of a packet from an external IP address to an internal IP address.

  You can use this rule type to provide access to your internal servers from external networks using public IP addresses.

  Source NAT: This rule type allows you to change the source IP address of a packet from an internal IP address to an external IP address. You can use this rule type to provide access to external networks from your internal servers using

  public IP addresses.

• Question 75:

  An NSX administrator would like to export syslog events that capture messages related to NSX host preparation events. Which message ID (msgld) should be used in the syslog export configuration command as a filler?

  A. MONISTORING

  B. SYSTEM

  C. GROUPING

  D. FABRIC

  Correct Answer: D

  According to the VMware NSX Documentation2, the FABRIC message ID (msgld) captures messages related to NSX host preparation events, such as installation, upgrade, or uninstallation of NSX components on ESXi hosts. The syslog export configuration command for NSX host preparation events would look something like this: set service syslog export FABRIC The other options are either incorrect or not relevant for NSX host preparation events. MONITORING captures messages related to NSX monitoring features, such as alarms and system events2. SYSTEM captures messages related to NSX system events, such as login, logout, or configuration changes2. GROUPING captures messages related to NSX grouping objects, such as security groups, security tags, or IP sets2. https://docs.vmware.com/en/VMware-NSX/4.1/ administration/GUID-CC18C0E3-D076-41AA-8B8C-133650FDC2E7.html

• Question 76:

  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:

  1.

  WKS-WEB-SRV-XXX

  2.

  WKY-APP-SRR-XXX

  3.

  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

  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: VMware NSX Documentation: Security Tag 1 VMware NSX Micro-segmentation Day 1: Chapter 4-Security Policy Design 2 VMware NSX 4.x Professional: Security Groups VMware NSX 4.x Professional: Security Policies

• Question 77:

  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

  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 uide, 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 VMware NSX 4.x Professional: NAT Configuration 4 VMware NSX 4.x Professional: NAT Troubleshooting 5

• Question 78:

  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.

  Correct Answer: D

  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 Tier0 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.

• Question 79:

  In which VPN type are the Virtual Tunnel interfaces (VTI) used?

  A. Route and SSL based VPNs

  B. Route-based VPN

  C. Policy and Route based VPNs

  D. SSL-based VPN

  Correct Answer: B

  Route-based VPN is a VPN type that uses Virtual Tunnel interfaces (VTI) to establish IPSec tunnels between an NSX Edge node and remote sites2. A VTI is a logical interface that is assigned an IP address and is associated with a physical or virtual interface. The VTI acts as an end point of the IPSec tunnel and routes traffic between the NSX Edge node and the remote site2. Route and SSL based VPNs, Policy and Route based VPNs, and SSL-based VPN are not VPN types that use VTI. References: Virtual Private Network (VPN)
