A company's medium-sized data center of almost 30 rack enclosures is adding another rack enclosure starting with redundant uninterruptible power supplies (UPSS), redundant power distribution units (PDUs), and redundant layer 2 switches. The switches have already been in production for a few years with up-to-date security settings, and the company will repurpose them with this new rack enclosure. However, the switch is currently not set to handle Dynamic Host Configuration Protocol (DHCP) traffic in any way. Additionally, the UPS and PDU devices are brand new. Before adding other devices to the rack, the data center administrators need to set up these devices for managing and monitoring.
As one of those administrators, your company has tasked you with networking these devices with a defense-in-depth strategy to secure them against tampering and abuse. The switches will allow new devices in the rack to securely receive a DHCP IP address for the initial setup. The switch ports should all be available for the initial setup and locked down after mounting and networking all other devices to the switch.
You must examine each device and determine which settings and configurations will properly harden these devices and prepare them to support rack servers, storage devices, and other network devices.
