container engine

[...] are software packages that contain an app and all dependencies for the app to run.

Containers

Containers [do/do not] run an OS in the container.

do not

Containers run on top of a [software type].

container engine

A container engine is run on a [...].

host OS (ie. Linux)

A [...] is a software platform for automating the deployment, management, scaling etc. of containers.

container orchestrator

Which boots up faster, a VM or a container?

a container

Which takes up more disk space, a VM or a container?

a VM

Which uses more CPU/RAM, a VM or a container?

a VM

Which is more isolated, a VM or a container?

a VM*because each VM runs its own OS, whereas containers all share the same OS

A [VM/container] runs its own OS instance.

What does VRF stand for?

Virtual Routing and Forwarding

Only Layer [...] interfaces can be configured in a VRF.

3

[...] can be configured to allow traffic to pass between VRFs.

VRF Leaking

VRF allows a router to build multiple [...]

routing tables

Without VRF, two interfaces on the same router [can/cannot] be in the same subnet.

cannot

Create a VRF:R1(config)# [...]

ip vrf vrf-name

Assign an interface to a VRF:R1(config-if)# [...]

ip vrf forwarding vrf-name

Show the routing table for a VRF:R1# [...]

show ip route vrf vrf-name

Ping in a VRF:R1# [...]

ping vrf vrf-name ip-address
