Which are two use-cases for the NSX Distributed Firewall' (Choose two.)

  1. Zero-Trust with segmentation
  2. Security Analytics
  3. Lateral Movement of Attacks prevention
  4. Software defined networking
  5. Network Visualization

Answer(s): A,C

Explanation:

Zero-Trust with segmentation is a security strategy that uses micro-segmentation to protect a network from malicious actors. By breaking down the network into smaller segments, the NSX Distributed Firewall can create a zero-trust architecture which limits access to only users and devices that have been authorized. This reduces the risk of a malicious actor gaining access to sensitive data and systems.
Lateral Movement of Attacks prevention is another use-case for the NSX Distributed Firewall. Lateral movement of attacks are when an attacker is already inside the network and attempts to move laterally between systems. The NSX Distributed Firewall can help protect the network from these attacks by controlling the flow of traffic between systems and preventing unauthorized access.

An administrator wants to configure NSX-T Security Groups inside a distributed firewall rule.
Which menu item would the administrator select to configure the Security Groups?

  1. System
  2. Inventory
  3. Security
  4. Networking

Answer(s): C

Explanation:

To configure NSX-T Security Groups inside a distributed firewall rule, the administrator would select the "Security" menu item in the NSX-T Manager user interface. Within the Security menu, the administrator would navigate to the "Groups" option, where they can create, edit, and manage security groups. These groups can then be used in the "Applied To" column when creating or editing firewall rules.
In the Security menu, administrator can also configure other security features such as firewall, micro- segmentation, intrusion detection and prevention, and endpoint protection.

An NSX administrator has turned on logging for the distributed firewall rule. On an ESXi host, where will the logs be stored?

  1. /var/log/esxupdate.log
  2. /var/log/dfwpktlogs.log
  3. /var/log/hostd.log
  4. /var/log/vmkerntl.log

Answer(s): B

Explanation:

The NSX administrator has enabled logging for the distributed firewall rule, and the logs are stored in the /var/log/dfwpktlogs.log file on the ESXi host. This log file stores the packet logs for the distributed firewall rules, and the logs can be used for auditing and troubleshooting the distributed firewall.

A Security Administrator needs to update their NSX Distributed IDS/IPS policy to detect new attacks with critical CVSS scoring that leads to credential theft from targeted systems.
Which actions should you take?

  1. · Update Distributed IDS/IPS signature database
    · Edit your profile from Security > Distributed IDS > Profiles · Select Critical severity, filter on attack type and select Successful Credential Theft Detected · Check the profile is applied in Distributed IDS rules
  2. · Edit your Distributed IDS rule from Security > Distributed IDS/IPS > Rules · Filter on attack type and select Successful Credential Theft Detected · Update Mode to detect and prevent
    · Click on gear icon and change direction to OUT
  3. · Create a new profile from Security > Distributed IDS > Profiles · Select Critical severity, filter on attack type and select Successful Credential Theft Detected · Check the profile is applied In Distributed IDS rules · Monitor Distributed IDS alerts to validate changes are applied
  4. · Edit your Distributed IDS rule from Security > Distributed IDS/IPS > Rules · Filter on attack type and select Successful Credential Theft Detected · Update Mode to detect and prevent
    · Click on gear icon and change direction to IN-OUT
