What’s the benefit of Multipathing?
routing redundancy
What is NIC Teaming?
combining multiple NICs to increase bandwidth and provide redundancy
What are Redundant Hardware/Clusters?

a smart power strip
What’s the difference between a Cold Site, Hot Site, and Warm Site?

Virtual Router Redundancy Protocol
FHRP

What parts of a network can be redundant?
ISP, Firewall, Router, Switch, Server, Storage
What’s the difference between FHRP and VRRP?
FHRP is the concept
VRRP is the implementation
Is VRRP Active-Active or Active-Passive?
Active-Passive
How is the default gateway IP handled in a VRRP?
the IP is shared as a virtual IP by the master until another router takes over

Mean Time To Repair
MTBF
Mean Time Before Failure
