Section 3.3 Flashcards
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?
backup devices/servers
What’s a PDU?

a smart power strip
What’s the difference between a Cold Site, Hot Site, and Warm Site?
Cold: space with no equipment or data
Hot: space with all equipment and data ready to go

Active-Passive: one device is on standby, ready to take over
VRRP
Virtual Router Redundancy Protocol
FHRP
First Hop Redundancy Protocol
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
MTTR

Recovery Time Objective
RPO
Recovery Point Objective
What is RTO?
max time allowed to recover
What is RPO?
max data loss allowed, measured in time
