NEW QUESTION # 31
What is an unprotected traffic flow in NSX Intelligence?
- A. A traffic flow that matches the default distributed firewall rule.
- B. A traffic flow that matches a reject rule more granular than the default.
- C. A traffic flow that matches an allow rule more granular than the default.
- D. A traffic flow that matches a drop rule more granular than the default.
Answer: A
Explanation:
An unprotected traffic flow in NSX Intelligence is a traffic flow that matches the default distributed firewall rule. The default rule is a catch-all rule which allows all traffic to pass through the distributed firewall, and any traffic flows that match this rule will be marked as unprotected. NSX Intelligence will then generate an alert for any unprotected traffic flows, allowing the administrator to take action to secure the traffic flow.

What needs to be configured on each transport node prior to using NSX-T Data Center Distributed Firewall time-based rule publishing?
- A. PAT
- B. DNS
- C. NAT
- D. NTP
Answer: D
Explanation:
In order to use NSX-T Data Center Distributed Firewall time-based rule publishing, the NTP (Network Time Protocol) needs to be configured on each transport node. This ensures that the transport nodes have accurate time synchronization, which is required for time-based rule publishing. Additionally, DNS (Domain Name System) and PAT (Port Address Translation) may also need to be configured on each transport node, depending on the desired configuration. Reference: [1] https://docs.vmware.com/en/VMware-NSX-T/2.5/com.vmware.nsxt.admin.doc/GUID-E9F8D8AD-7AF1-4F09-B62C-6A17A6F39A6C.html [2] https://docs.vmware.com/en/VMware-NSX-T/2.4/com.vmware.nsxt.admin.doc/GUID-E9F8D8AD-7AF1-4F09-B62C-6A17A6F39A6C.html
NEW QUESTION # 44
Which two are true of the NSX Gateway Firewall? (Choose two.)
- A. Firewall rules in System category cannot be edited.
- B. Firewall rules in Pre Rule category are applied to all gateways.
- C. Applied-To can be configured at Firewall Policy level.
- D. NAT service can be configured in NSX Gateway Firewall policy.
- E. Security Groups can be used in Applied-To column.
Answer: B,E
Explanation:
NSX Gateway Firewall is a distributed firewall that provides security for east-west traffic within a virtual environment.
1. Firewall rules in Pre Rule category are applied to all gateways. This category contains system-defined rules that are always applied first to all gateways and cannot be modified. These rules include the default deny all rule and others that control basic connectivity.
2. Security Groups can be used in Applied-To column. Security groups allow you to group together VMs that have similar security requirements and then apply firewall policies to those groups. This way you can apply the same security rules to multiple VMs at once, instead of configuring the rules on each individual VM.

NEW QUESTION # 45
Which dot color indicates an on-going attack of medium severity in the IDS/IPS events tab of NSX-T Data Center?
- A. blinking yellow dot
- B. solid red dot
- C. blinking orange dot
- D. solid orange dot
Answer: D
Explanation:
The dot color that indicates an on-going attack of medium severity in the IDS/IPS events tab of NSX-T Data Center is a solid orange dot. This indicates that the attack has been detected and is ongoing at a medium severity level.
Reference:
In the IDS/IPS events tab of NSX-T Data Center, different colors of dots are used to indicate the severity of an attack.
A solid red dot indicates a critical attack, which is the highest severity level.
A solid orange dot indicates a medium attack, which is a moderate severity level.
A solid yellow dot indicates a low attack, which is the lowest severity level.
In this case, a solid orange dot is used to indicate an on-going attack of medium severity in the IDS/IPS events tab of NSX-T Data Center.
It's worth noting that there is no blinking dots in this context, all the dots are solid.

NEW QUESTION # 48
Refer to the exhibit.
A security administrator is configuring a time window to create a time-based distributed firewall rule. While configuring the time window, an error displayed as shown in the exhibit. Which action will resolve the problem?
- A. Change the time window interval.
- B. Change the time windows frequency
- C. Configure the ESXl host to use a remote NTP server.
- D. Restart me NTP service on the ESXl host.
Answer: C
Explanation:
The most likely action to resolve the problem is to configure the ESXi host to use a remote NTP server. The time window requires the ESXi host to be synchronized to a time source in order to properly calculate the time window, and the error is likely due to the ESXi host not being synchronized. Configuring the ESXi host to use a remote NTP server should ensure that the host is properly synchronized, and allow the time window to be configured correctly.

Answer: C
NEW QUESTION # 50
What must an administrator deploy to provide Linux based VMs with antivirus protection?
- A. Guest Customization Agent
- B. Antivirus Agent in vCenter
- C. Guest Introspection Thin Agent
- D. Antivirus Agent in NSX
Answer: C
Explanation:
NSX provides a feature called Guest Introspection that allows administrators to provide security services to virtual machines, including antivirus protection. One of the components of Guest Introspection is the Guest Introspection Thin Agent, which must be deployed to provide Linux-based VMs with antivirus protection. The Thin Agent is a lightweight agent that runs inside the guest operating system of virtual machines and communicates with the NSX Manager to provide security services.
Once the Guest Introspection Thin Agent is deployed, the administrator can configure the antivirus service to scan virtual machines for malware and take action on any threats that are detected.
Reference:
VMware NSX Guest Introspection documentation https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.1/com.vmware.nsxt.guest_introspection.doc/GUID-A86FBAF1-A8D9-4E12-8F3D-04B3D89B8F7E.html VMware NSX Guest Introspection Thin Agent documentation https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.1/com.vmware.nsxt.guest_introspection.doc/GUID-A86FBAF1-A8D9-4E12-8F3D-04B3D89B8F7E.html
NEW QUESTION # 51
An administrator needs to configure their NSX-T logging to audit changes on firewall security policy. The administrator Is using the following command from NSX-T3.1 documentation :
Which Message ID from the following list will allow the administrator to track changes on firewall security rules?
- A. MONITOR
- B. FIREWALL
- C. FABRIC
- D. SYSTEM
Answer: B
Explanation:
The message ID that will allow the administrator to track changes on firewall security rules is "FIREWALL". This message ID is part of the NSX-T3.1 documentation and will be used to log any changes made to the firewall security policy. This will allow the administrator to easily audit and track any changes made to the policy.
