質問 # 10
What is the default action of the Default Layer 3 distributed firewall rule?
- A. Allow
- B. Drop
- C. Forward
- D. Reject
正解：B
解説：
The Default Layer 3 distributed firewall rule is a system-defined rule in NSX-T Data Center that applies to all distributed firewall sections. By default, this rule is set to drop all traffic, meaning that any traffic that does not match a specific rule will be dropped.
For more information on the Default Layer 3 distributed firewall rule and how to configure it, please refer to the NSX-T Data Center documentation: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/nsx-t-3.0-firewall/GUID-B6B835F2-B6F2-4468-8F8E-6F7B9B9D6E91.html
質問 # 11
Which two are true of the NSX Gateway Firewall? (Choose two.)
- A. Firewall rules in Pre Rule category are applied to all gateways.
- B. Security Groups can be used in Applied-To column.
- C. NAT service can be configured in NSX Gateway Firewall policy.
- D. Applied-To can be configured at Firewall Policy level.
- E. Firewall rules in System category cannot be edited.
正解：A、B
解説：
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.

Which three security objects are provided as an output in a recommendation session in NSX Intelligence? (Choose three.)
- A. distributed firewall rules
- B. security service
- C. context profiles
- D. security groups
- E. gateway firewall rules
正解：A、B、E
解説：
NSX Intelligence uses machine learning algorithms to analyze network traffic and provide recommendations for security and compliance. These recommendations include the following security objects:
Distributed Firewall Rules: Distributed firewall rules are used to control traffic between virtual machines within a logical network. NSX Intelligence can recommend new distributed firewall rules based on traffic patterns it observes in the network.
Security Service: Security services are used to protect virtual machines and networks from threats. NSX Intelligence can recommend new security services to be deployed based on traffic patterns it observes in the network.
Security Groups: Security groups are used to group virtual machines and networks together for security and management purposes. NSX Intelligence can recommend new security groups to be created based on traffic patterns it observes in the network.
1. context profiles are not an output from a recommendation session in NSX Intelligence. It is used to define the context of the network traffic that is being analyzed, such as the type of device, the network location, or the user.
2. gateway firewall rules are not an output from a recommendation session in NSX Intelligence. Gateway firewall rules are used to control traffic between logical networks, such as between a VLAN and a VXLAN, or between a logical network and the physical network.

質問 # 20
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. Configure the ESXl host to use a remote NTP server.
- B. Change the time window interval.
- C. Change the time windows frequency
- D. Restart me NTP service on the ESXl host.
正解：A
解説：
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.

質問 # 30
In a brownfield environment with NSX-T Data Center deployed and configured, a customer is interested in Endpoint Protection integrations. What recommendation should be provided to the customer when it comes to their existing virtual machines?
- A. A custom install of VMware tools is required to select the drivers.
- B. Virtual machine hardware should be version 10 or higher.
- C. A minimum installation of VMware tools is required.
- D. Virtual machine must be protected by vSphere HA.
正解：A
解説：
Endpoint Protection (EPP) integrations with NSX-T Data Center typically involve installing a security agent on the virtual machines (VMs) in the environment. This agent communicates with the NSX-T Data Center platform to provide security features such as antivirus and intrusion detection.
In order for the agent to work properly, it is important that the correct drivers are installed on the VMs. Typically, this is done by installing VMware tools on the VMs, which provides the necessary drivers. However, in a brownfield environment, the VMs may already have VMware tools installed and the drivers may not be the correct version for the agent to work properly. In this case, it is recommended to perform a custom install of VMware tools and select the drivers specifically for the agent.

What is an unprotected traffic flow in NSX Intelligence?
- A. A traffic flow that matches a drop rule more granular than the default.
- B. A traffic flow that matches the default distributed firewall rule.
- C. A traffic flow that matches an allow rule more granular than the default.
- D. A traffic flow that matches a reject rule more granular than the default.
正解：B
解説：
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.
