The Dynamic Host Configuration Protocol (DHCP) is responsible for automatically assigning IP addresses to devices on a network. When a device connects to the network, it sends a broadcast request for an IP address, and a DHCP server responds with an IP address, subnet mask, default gateway, and DNS server information. This process simplifies network administration by automating IP address assignment and ensuring that devices have unique IP addresses without manual configuration.

RFC 2131: DHCP

The provided script sends a POST request to the Meraki API endpoint to add a new media server for monitoring. The payload includes the name and address of the media server, indicating that the action being automated is the addition of a media server to the monitoring list.

Network Address Translation (NAT) on the firewall is responsible for translating the public IP address to the private IP addresses of internal servers. If traffic is being forwarded to the wrong server, it indicates a misconfiguration in the NAT rules.

NAT Configuration: NAT rules need to be correctly configured to forward traffic to the appropriate internal server based on the destination IP and port.

Misconfiguration: If NAT rules are incorrect, traffic may be directed to the wrong internal IP address, as seen in the exhibit where traffic is sent to server 1 instead of server 2.

Option D is correct as the issue is caused by NAT misconfiguration on the firewall.

During the integration step of the CI/CD pipeline, code from multiple developers is combined. This step involves compiling the code and running tests to ensure that the different components work together correctly. It is a critical phase for identifying integration issues early in the development cycle.
