What does the configured firewall rule allow on ESXi 6.x?

  1. Connections from the ESXi host to all devices on the 192.168.1.0 network and 192.168.2.220 on port 22 are allowed.

  2. Connections coming from IP addresses from the 192.168.1.0 network and 192.168.2.220 on port 22 are allowed.

  3. TCP Connections coming from IP addresses from the 192.168.1.0 network and 192.168.2.220 on port 22 are not allowed.

  4. TCP Connections from the ESXi host to all devices on the 192.168.1.0 network and 192.168.2.220 on port 22 are not allowed.

The correct answer is: Connections coming from IP addresses from the 192.168.1.0 network and 192.168.2.220 on port 22 are allowed.

The configured firewall rule allows connections from IP addresses within the 192.168.1.0 network and the specific IP address 192.168.2.220 on port 22. This means that the firewall is set up to permit incoming network traffic from these sources, which suggests that any device or user attempting to initiate a connection from those IP ranges to the ESXi host on port 22 will be able to do so successfully. Port 22 is commonly used for SSH (Secure Shell) access, which is typically employed for secure remote management of ESXi hosts. By allowing connections from specified IP addresses, administrators can maintain control over which devices can access the host, enhancing both security and functionality. Properly configuring firewall rules in this manner is crucial for secure management of virtualization infrastructures, ensuring only trusted sources can communicate with critical systems. In contrast, options implying restrictions or a lack of connection capabilities do not accurately reflect the intended purpose of the firewall rule as described in the correct choice. Therefore, the focus on allowed connections aligns with standard practices in network security management.
