The security administrator turns on logging for a firewall rule.
Where is the log stored on an ESXi transport node?
A. /var/log/vmware/nsx/firewall.log
B. /var/log/messages.log
C. /var/log/dfwpktlogs.log
D. /var/log/fw.log
Correct Answer: C
The log for a firewall rule on an ESXi transport node is stored in the /var/log/dfwpktlogs.log file. This file contains information about the packets that match or do not match the firewall rules, such as the source and destination IP addresses, ports, protocols, actions, and rule IDs. The log file can be viewed using the esxcli network firewall get command or the vSphere Client. https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-D57429A1-A0A9-42BE-A299-0C3C3546ABF3.html
Question 52:
Which Is the only supported mode In NSX Global Manager when using Federation?
A. Controller
B. Policy
C. Proxy
D. Proton
Correct Answer: B
NSX Global Manager is a feature of NSX that allows managing multiple NSX domains across different sites or clouds from a single pane of glass. NSX Global Manager supports Federation, which is a capability that enables synchronizing configuration and policy across multiple NSX domains. Federation has many benefits such as simplifying operations, improving resiliency, and enabling disaster recovery. The only supported mode in NSX Global Manager when using Federation is Policy mode. Policy mode means that NSX Global Manager acts as a policy manager that defines and distributes global policies to local NSX managers in different domains. Policy mode also allows local NSX managers to have their own local policies that can override or merge with global policies. https://docs.vmware.com/en/VMware-NSX/4.0/administration/GUID-29998FC5-C1AB-40BC-B669-6E8E9937F345.html
Question 53:
Which three data collection sources are used by NSX Network Detection and Response to create correlations/Intrusion campaigns? (Choose three.)
A. Files and anti-malware (lie events from the NSX Edge nodes and the Security Analyzer
B. East-West anti-malware events from the ESXi hosts
C. Distributed Firewall flow data from the ESXi hosts
D. IDS/IPS events from the ESXi hosts and NSX Edge nodes
E. Suspicious Traffic Detection events from NSX Intelligence
Correct Answer: ADE
The correct answers are A. Files and anti-malware (file) events from the NSX Edge nodes and the Security Analyzer, D. IDS/IPS events from the ESXi hosts and NSX Edge nodes, and E. Suspicious Traffic Detection events from NSX Intelligence. According to the VMware NSX Documentation3, these are the three data collection sources that are used by NSX Network Detection and Response to create correlations/intrusion campaigns. The other options are incorrect or not supported by NSX Network Detection and Response. East-West anti-malware events from the ESXi hosts are not collected by NSX Network Detection and Response3. Distributed Firewall flow data from the ESXi hosts are not used for correlation/intrusion campaigns by NSX Network Detection and Response3. https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-14BBE50D-9931-4719-8FA7-884539C0D277.html
Question 54:
Which CLI command on NSX Manager and NSX Edge is used to change NTP settings?
A. get timezone
B. get time-server
C. set timezone
D. set ntp-server
Correct Answer: D
The CLI command on NSX Manager and NSX Edge that is used to change NTP settings is set ntp-server. This command allows the user to configure one or more NTP servers for time synchronization12. The other options are incorrect because they are not valid CLI commands for changing NTP settings. The get timezone and set timezone commands are used to display and configure the timezone of the system1. The get time-server command is used to display the current time server configuration1. There are no CLI commands for using RADIUS or BootP for NTP settings.

Question 55:
Which CLI command is used for packet capture on the ESXi Node?
A. tcpdump
B. debug
C. pktcap-uw
D. set capture
Correct Answer: C
According to the VMware Knowledge Base, this CLI command is used for packet capture on the ESXi node. pktcap-uw stands for Packet Capture User World and is a tool that allows you to capture packets from various points in the network
stack of an ESXi host. You can use this tool to troubleshoot network issues or analyze traffic flows. The other options are either incorrect or not available for this task. tcpdump is not a valid CLI command for packet capture on the ESXi node,
as it is a tool that runs on Linux systems, not on ESXi hosts. debug is not a valid CLI command for packet capture on the ESXi node, as it is a generic term that describes the process of finding and fixing errors, not a specific tool or command.
set capture is not a valid CLI command for packet capture on the ESXi node, as it does not exist in the ESXi CLI.

Question 56:
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
Correct Answer: DF
BGP will be configured on the T0 SR. Connect to the VRF for the T0 SR and run get bgp neighbor once connected to it. https://docs.vmware.com/en/VMware-Validated-Design/5.1/sddc-deployment-of-vmware-nsx-t-workload-domains-withmultiple-availability-zones/GUID-8BD4228A-75C6-4C60-80B4-538D4297E11A.html For the BGP configuration on NSX-T, the Tier-0 Service Router (SR) is typically where BGP is configured. To check the BGP neighbor status:
Connect to the VRF for the T0 SR, which is VRF 3 based on the provided output. Run the command to get BGP neighbor status once connected to it.
Question 57:
An administrator needs to download the support bundle for NSX Manager. Where does the administrator download the log bundle from?
A. System > Utilities > Tools
B. System > Support Bundle
C. System > Settings > Support Bundle
D. System > Settings
Correct Answer: C
It's "support bundle" on the "system" page, all right, but it's in the "settings" chapter.
Question 58:
Which of the following settings must be configured in an NSX environment before enabling stateful active-active SNAT?
A. Tier-1 gateway in active-standby mode
B. Tier-1 gateway in distributed only mode
C. An Interface Group for the NSX Edge uplinks
D. A Punting Traffic Group for the NSX Edge uplinks
Correct Answer: C
To enable stateful active-active SNAT on a Tier-0 or Tier-1 gateway, you must configure an Interface Group for the NSX Edge uplinks. An Interface Group is a logical grouping of NSX Edge interfaces that belong to the same failure domain. A failure domain is a set of NSX Edge nodes that share the same physical network infrastructure and are subject to the same network failures. By configuring an Interface Group, you can ensure that the stateful services are distributed across different failure domains and can recover from network failures1
Question 59:
How is the RouterLink port created between a Tier-1 Gateway and Tier-O Gateway?
A. Automatically created when Tier-1 is connected with Tier-0 from NSX UI.
B. Automatically created when Tier-1 is created.
C. Manually create a Logical Switch and connect to bother Tier-1 and Tier-0 Gateways.
D. Manually create a Segment and connect to both Tier-1 and Tier-0 Gateways.
Correct Answer: A
The RouterLink port is automatically created when a Tier-1 Gateway is connected with a Tier-0 Gateway from the NSX UI1. The RouterLink port is a logical interface that is assigned an IP address and is associated with a physical or virtual interface. The RouterLink port acts as an end point of the IPSec tunnel and routes traffic between the Tier-1 Gateway and the Tier-0 Gateway2. The other options are incorrect because they involve manual creation of logical switches or segments, which are not required for RouterLink port creation.

Question 60:
Which three NSX Edge components are used for North-South Malware Prevention? (Choose three.)
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
