If you enter a wireless hotspot at an airport or coffee shop, DHCP
makes it possible for you to access the Internet. As you enter the area,
your laptop DHCP client contacts the local DHCP server via a wireless
connection. The DHCP server assigns an IPv4 address to your laptop.
Various types of devices can be DHCP servers as long as they are
running DHCP service software. With most medium to large networks, the
DHCP server is usually a local, dedicated PC-based server.
With home networks, the DHCP server may be located at the ISP and
a host on the home network receives its IPv4 configuration directly
from the ISP, as shown in the figure.
Many home networks and small businesses use a wireless router and
modem. In this case, the wireless router is both a DHCP client and a
server. The wireless router acts as a client to receive its IPv4
configuration from the ISP and then acts as a DHCP server for internal
hosts on the local network. The router receives the public IPv4 address
from the ISP, and in its role as a DHCP server, it distributes private
addresses to internal hosts.
In addition to PC-based servers and wireless routers, other types
of networking devices such as dedicated routers can provide DHCP
services to clients, although this is not as common.

https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl # will already be pre-configured export do = "--dry-run=client -o yaml" # k get pod x $do export now = "--force --grace-period 0" # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section . Question 1 | Contexts Task weight: 1% You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
