East-West service insertion refers to the ability to insert security services, such as firewall and intrusion detection and prevention, between virtual machines (VMs) that are communicating within the same logical network.

One of the insertion points for East-West service insertion is the virtual network interface card (vNIC) of the guest VM. The vNIC is the virtual representation of a physical NIC on a VM, and it connects the VM to the virtual network. By inserting security services at the vNIC level, traffic between VMs can be inspected and secured before it reaches the virtual switch.

The administrator is using the command syntax found in the NSX-T 3.1 documentation to configure a remote logging server to send firewall connections and packets logs. In order to complete the configuration task, the administrator needs to use the correct options for the command.

The options used in the command are: logging-server: This option specifies the IP address or hostname of the remote logging server. In this case, the IP address of the remote logging server is 192.168.110.60. proto: This option specifies the protocol to be used to send the logs to the remote server. In this case, the protocol used is UDP. level: This option specifies the level of logging to be sent to the remote server. In this case, the level of logging is "info" facility: This option specifies the facility to be used for syslog messages. In this case, the facility used is "syslog" message Id: This option specifies the message Id that will be used for the logs. In this case, the message Id used is "FIREWALL-PKTLOG"

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: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.1/nsxt_31_admin_guide/GUID-A8FAC8A1-F9F9-43EC-A822-F2F2CB5C5E5A.html#GUIDA8FAC8A1- F9F9-43EC-A822-F2F2CB5C5E5A

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.

vSphere Tags are labels that can be used to group and categorize virtual machines and other objects.

The security administrator can create a tag for quarantined VMs and assign it to any VMs that are confirmed to be infected. This will help identify and isolate the infected VMs more quickly and easily in the future.

NSX Intelligence uses machine learning algorithms to analyze network traffic and provide recommendations for security and compliance. The administrator can configure the time range of the input entities to be analyzed, so that the recommendations are based on changes in the scope of the input entities over that period of time.

To achieve the requirement of getting recommendations based on the changes in the scope of the input entities every hour, the administrator needs to adjust the time range to 1 hour. This will ensure that the analysis and recommendations are based on the most recent hour of network traffic.

Zero-Trust Networks is a security concept that assumes that all devices, users, and networks are untrusted until they can be verified. This means that all network-connected devices must be verified for their identity and integrity before they are granted access to resources. This is done continually, meaning that devices are verified every time they try to access a resource, rather than being trusted permanently.

1. Network connected devices should only be trusted if their identity and integrity can be verified continually. This is the main concept of Zero-Trust Networks, every device that wants to access the network should be authenticated and verified its identity and integrity.

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.

A. 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.

D. 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.
