Microsoft Azure is an example of which type of cloud deployment model?
Public cloud.
Microsoft Azure is an example of the the public cloud deployment model. A public cloud is a platform that uses the standard cloud computing model to make resources, such as VMs, applications, or storage, available to users remotely.
The primary reason for cloud technology adoption.
What is scalability.
The cloud is all about freedom. Increased scalability, scalability the king of the cloud jungle!
Runs a test environment and designed to prove that a technology works as it should.
What is (PoC) Proof of Concept.
Works at the file level or the block level to provide storage solutions by eliminating files or blocks that have redundant data.
Deduplication
works at the file level or the block level to provide storage solutions by eliminating files or blocks that have redundant data.
How many questions and what type of questions are on the Cloud Essentials+ certification?
75
Multiple Choice
Is measured in terms of nines, or how many nines of uptime the provider guarantees.
What is High Availability.
High availability is measured in terms of nines, or how many nines of uptime the provider guarantees. More nines mean more money, and different aspects of your service contract might required different levels of uptime.
Refers to tracking usage for a group or department and then billing it accordingly.
What is Chargeback.
Which migration approach are all applications and data migrated as it is?
What is Lift and Shift.
What two major categories of storage, one refers to the data that isn't needed very often and it might take from several minutes to several days to make the data available to access. Second, refers to the data that is readily available at all times.
Cold storage refers to the data that isn't needed very often and it might take from several minutes to several days to make the data available to access.
Hot storage refers to the data that is readily available at all times.
What is the cost to take the Cloud Essentials+ certification with CompTIA?
$138
