• Question 2:

  An architect receives a request to apply distributed firewall in a customer environment without making changes to the network and vSphere environment. The architect decides to use Distributed Firewall on VDS.

  Which two of the following requirements must be met in the environment? (Choose two.)

  A. vCenter 8.0 and later
  B. NSX version must be 3.2 and later
  C. NSX version must be 3.0 and later
  D. VDS version 6.6.0 and later
  B. NSX version must be 3.2 and later
  D. VDS version 6.6.0 and later

  ---

  Explanation/Reference:

  Distributed Firewall on VDS is a feature of NSX-T Data Center that allows users to install Distributed Security for vSphere Distributed Switch (VDS) without the need to deploy an NSX Virtual Distributed Switch (N-VDS). This feature provides

  NSX security capabilities such as Distributed Firewall (DFW), Distributed IDS/IPS, Identity Firewall, L7 App ID, FQDN Filtering, NSX Intelligence, and NSX Malware Prevention. To enable this feature, the following requirements must be met in

  the environment:

  The NSX version must be 3.2 and later1. This is the minimum version that supports Distributed Security for VDS.

  The VDS version must be 6.6.0 and later1. This is the minimum version that supports the NSX host preparation operation that activates the DFW with the default rule set to allow.

• Question 3:

  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
  D. FABRIC

  ---

  Explanation/Reference:

  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 4:

  An administrator has deployed 10 Edge Transport Nodes in their NSX Environment, but has forgotten to specify an NTP server during the deployment.

  What is the efficient way to add an NTP server to all 10 Edge Transport Nodes?

  A. Use Transport Node Profile
  B. Use the CU on each Edge Node
  C. Use a Node Profile
  D. Use a PowerCU script
  C. Use a Node Profile

  ---

  Explanation/Reference:

  A node profile is a configuration template that can be applied to multiple NSX Edge nodes or transport nodes at once. A node profile can include settings such as NTP server, DNS server, syslog server, and so on1. By using a node profile, an administrator can efficiently configure or update the network settings of multiple NSX Edge nodes or transport nodes in a single operation2. The other options are incorrect because they are either not efficient or not supported. Using the CLI on each Edge node would require manual and repetitive commands for each node, which is not efficient. Using a Transport Node Profile would not work, because a Transport Node Profile is used to configure the NSX-T Data Center components on a transport node, such as the transport zone, the N-VDS, and the uplink profiles3. Using a PowerCLI script might work, but it would require writing and testing a custom script, which is not as efficient as using a built-in feature like a node profile.

• Question 5:

  Which two BGP configuration parameters can be configured in the VRF Lite gateways? (Choose two.)

  A. Graceful Restart
  B. BGP Neighbors
  C. Local AS
  D. Route Distribution
  E. Route Aggregation
  B. BGP Neighbors
  E. Route Aggregation

  ---

  Explanation/Reference:

  Route Aggregation and and D) BGP neighbours are available when configuring BGP in a VRF. "Route distribution" does not exist, what you can do is a "Route Re-Distribution" via BGP. https://docs.vmware.com/en/VMware-NSX/4.1/administration/GUID-4CB5796A-1CED-4F0E-ADE0-72BF7B3F762C.html

• Question 6:

  An NSX administrator wants to create a Tler-0 Gateway to support equal cost multi-path (ECMP) routing. Which failover detection protocol must be used to meet this requirement?

  A. Bidirectional Forwarding Detection (BFD)
  B. Virtual Router Redundancy Protocol (VRRP)
  C. Beacon Probing (BP)
  D. Host Standby Router Protocol (HSRP)
  A. Bidirectional Forwarding Detection (BFD)

  ---

  Explanation/Reference:

  According to the VMware NSX 4.x Professional documents and tutorials, BFD is a failover detection protocol that provides fast and reliable detection of link failures between two routing devices. BFD can be used with ECMP routing to monitor the health of the ECMP paths and trigger a route change in case of a failure12. BFD is supported by both BGP and OSPF routing protocols in NSX-T3. BFD can also be configured with different timers to achieve different detection times3.

• Question 7:

  Which two are supported by L2 VPN clients? (Choose two.)

  A. NSX for vSphere Edge
  B. 3rd party Hardware VPN Device
  C. NSX Autonomous Edge
  D. NSX Edge
  C. NSX Autonomous Edge
  D. NSX Edge

  ---

  Explanation/Reference:

  The following L2 VPN clients are recommended:

  1.

  NSX Managed NSX Edge in a separate NSX Managed environment.

  Overlay and VLAN segments can be extended.

  2.

  Autonomous Edge:

  Enables L2 VPN access from a non-a NSX environment to NSX environments.

  Deployed by using an OVF file on a host that is not managed by NSX.

  Only VLAN segments can be extended.

• Question 8:

  An administrator wants to validate the BGP connection status between the Tier-O Gateway and the upstream physical router.

  What sequence of commands could be used to check this status on NSX Edge node?

  A. set vrf show logical-routers show bgp
  B. show logical-routers get vrf show ip route bgp
  C. get gateways vrf get bgp neighbor
  D. enable get vrf show bgp neighbor
  C. get gateways vrf get bgp neighbor

  ---

  Explanation/Reference:

  The sequence of commands that could be used to check the BGP connection status between the Tier-O Gateway and the upstream physical router on NSX Edge node is get gateways, vrf , get bgp neighbor. These commands can be executed on the NSX Edge node CLI after logging in as admin6. The first command, get gateways, displays the list of logical routers (gateways) configured on the Edge node, along with their IDs and VRF numbers7. The second command, vrf , switches to the VRF context of the desired Tier-O Gateway, where is the VRF number obtained from the previous command7. The third command, get bgp neighbor, displays the BGP neighbor summary for the selected VRF, including the neighbor IP address, AS number, state, uptime, and prefixes received8. The other options are incorrect because they either use invalid or incomplete commands or do not switch to the correct VRF context.

• Question 9:

  What are four NSX built-in rote-based access control (RBAC) roles? (Choose four.)

  A. Network Admin
  B. Enterprise Admin
  C. Full Access
  D. Read
  E. LB Operator
  F. None
  G. Auditor
  A. Network Admin
  B. Enterprise Admin

  Match the NSX Intelligence recommendations with their correct purpose.

  Select and Place:

  

  

  ---

  Explanation/Reference:

  Security policy recommendations: Are East-West distributed firewall (DFW) security policies in the application category12.

  Security group recommendations: Are VMs or physical servers whose traffic flows were analyzed for the time period and the boundary you had specified12. Service recommendations: Are service objects that were used by applications in the

  VMs or physical servers that you had specified, but the services are not yet defined in the NSX inventory12.
