This device is a network-accessible remote management tool. It uses the STUN protocol and public TURN servers to provide remote management to our MS-01 servers.
What is a JetKVM?

This in IPv6 is equivalent of the subnet mask in IPv4. However, rather than being expressed in four octets like it is in IPv4, it is expressed as an integer between 1 through 128.
What is "Prefix Length"?
100
In addition to `kubectl`, this CLI tool is used to view and manage the Kubernetes cluster resources.
That is "k9s"?
100
This type of hypervisor runs directly on the host’s hardware to control the hardware and manage guest operating systems.
What is a Type-1 hypervisor?
What is a bare-metal hypervisor?

This RFC defines a new routing scheme for the current version of the Internet Protocol version 6 (IPv6) in the spirit of "Green IT", whereby packets will be routed to get as much fresh-air time as possible.
(Googling is fine for this question)

This is the total storage amount of our Ceph cluster.
(Whoever get the closest to the number reported by Proxmox gets the points.)
What is 14.55TB?
200
This is our prefix length for the cluster network.
The first __ bits of the 128 bit address are fixed.
What is /64?
(Our network is fcd5:2d46:cdc1:a358::/64)

This tool is used to create cluster configurations and manage a Talos Linux cluster via the Talos API.
What is talosctl?
200
This system provides a distributed file system in a Proxmox datacenter to allow quick VM migration and shared storage across nodes.
What is Ceph / RADOS?
200
In the book "Phippy goes to the Zoo", this is the name of Phippy's niece.
Who is "Zee"?
300
Our patch panel utilizes this type of connector to connect two CAT6 cables together.
The other common type is called a Keystone jack and requires a punchdown tool to setup.
What is a coupler?
300
This is the maximum theoretical speed of the `speed1` network bridge in our cluster.
What is 10Gbps?
300
This Kubernetes resource provides a method of connecting applications with the external network. It lets you map traffic to different services based on rules you define via the Kubernetes API.
What is a Kubernetes Ingress?
300
These are the two types of virtualization technologies that Proxmox supports.
What is KVM (Kernel-based Virtual Machines)?
What is LXC (Linux Containers)?
300
This is a policy mechanism that helps to protect websites against man-in-the-middle attacks such as protocol downgrade attacks and cookie hijacking. It allows web servers to declare that web browsers should automatically interact with it using only HTTPS connections.
What is HSTS (HTTP Strict Transport Security)?
400
*Daily Double!*
On the 48-port PoE switch in our half-rack, this Ubiquity feature illuminates each port with RGB colors. By default, the different colors indicate port speed.
What is Etherlighting?
400
Routers use this message to announce their presence, network parameters, and other configuration options to hosts over an IPv6 network.
What is a Router Advertisement?
400
This application follows the GitOps pattern of using Git repositories as the source of truth for defining the desired application state. It provides a declarative continuous delivery system to sync cluster state with declarative yaml files in Git.
What is ArgoCD?
400
This daemon within a Ceph cluster is generally provisioned for every physical storage device. It manages data on local storage with redundancy and provides access to that data over the network.
What is a Ceph OSD (Object Storage Daemon)?
400
This is a communication protocol for discovering the link layer address, such as a MAC address, associated with a internet layer address, typically an IPv4 address.
What is ARP (Address Resolution Protocol)?
500
This port is an extension of the full-size SAS port. This interface is used only on 2.5" SSDs and provides multiple simultaneous lanes of data communication between an SSD and the host computer. The MS-01 servers support this connector.
What is U.2?
500
This Wifi revision is also known as "Extremely High Throughput (EHT)." It supports up to 23 Gbps. On our half rack access point, it supports up to 8.6 Gbps.
What is WiFi 7 (802.11be)?
500
In Talos Linux, this feature automates the setup and maintenance of a full mesh WireGuard network for a cluster, giving the ability to operate hybrid Kubernetes clusters that can span the edge, datacenter, and cloud.
What is Kubespan?
500
This Proxmox storage type utilizes Ceph and can only be used for storing VM and container block devices.
What is RBD (RADOS Block Device)?
500
This is a networking protocol that provides centralized authentication, authorization, and accounting (AAA) management for users who connect and use a network service. This is often the back-end of choice for 802.1X authentication.
What is RADIUS (Remote Authentication Dial-In User Service)?
