Section 3.4 Flashcards
What is server clustering?
This is when you have multiple servers operating together as one big server.
What is load balancing?
Load balancing uses a load balancer to distribute the load across multiple servers.
What is site resiliency?
This is a recovery site that has data synchronized and it is activated if a disaster happens in the active site. This is a backup plan to increase site resiliency.
What is a Hot site?
A hot site is an exact replicate of the datacenter. It contains all of the hardware and application software and data that the main datacenter contains. This hot site is used in case of a disaster in the datacenter.
What is a Cold Site?
An empty building that is ready to be turned into a hot site in case of a disaster.
What is a Warm Site?
This is a site that’s between a hot site and a cold site. It has some of the physical equipment, applications and data as the main datacenter.
What is COOP?
Continuity of Operations Planning (COOP) is a plan that’s designed to think of a disaster that can cause a disruption to the norm.
For example if the technology is down, you may need to process transactions manually over the phone using a transaction book.
What is capacity planning?
It’s planning to match supply to the demand.
What is a Tabletop Exercise?
A tabletop exercise is a simulation of a disaster recovery. The purpose is to test the logistics and processes in case of a disaster. The idea is to get all of the Key Players together and talk through the simulated disaster.
What is a fail over test?
The purpose of this test is to test if the redundant configurations are able to switch over in case there is a failure.
What is “Going Phishing”?
This is a term used for a test which created a phishing email attack and send it to the actual user community to see who in the community would fall for such an event.
What is a Simulation test?
These are test to simulate events such as a phishing attack, password requests, data breaches, etc.
What is Parallel Processing?
Parallel processing allows us to split a process though multiple parallel CPUs. This improves performance and recovery.
What is a Snapshot backup?
A snapshot backup is a popular backup method for Virtual Machines. This takes an instant backup of the entire VM at the state during the backup time.
What is a replication backup?
Replication is an ongoing, almost real time backup that keeps the data synchronized in multiple locations.
