73
Q

What is a region?

A

It is a geographical area on the planet containing at least one, but potentially multiple datacenters that are in close proximity and networked together with a low-latency network.

74
Q

What is a geography?

A

It is a discrete market typically containing two or more regions that preserve data residency and compliance boundaries.

75
Q

What are availability zones?

A

They are physically separate datacenters within an Azure region.

76
Q

What is a region pair?

A

Each Azure region is always paired with another region within the same geography (such as US, Europe, or Asia) at least 300 miles away.

77
Q

What are the four common techniques for performing compute in Azure?

A
  • virtual machines
  • containers
  • azure app service
  • serverless computing
78
Q

What are virtual machines?

A

They are software emulations of physical computers.

79
Q

What are containers?

A

They are a virtualization environment but, unlike a virtual machine, they do not include an operating system. Instead, they reference the operating system of the host environment that runs the container.

80
Q

What is Azure App Service?

A

It is a platform-as-a-service (PaaS) offering in Azure that is designed to host enterprise-grade web-oriented applications.

81
Q

What is Serverless Computing?

A

It is a cloud-hosted execution environment that runs your code but completely abstracts the underlying hosting environment.

82
Q

What’s an availability set?

A

It is a logical grouping of two or more VMs that ensure your application remains available during planned or unplanned maintenance.

Azure creates two fault domains (two racks each having dedicated power and network resources), and five logical update domains.

83
Q

It allows you to perform analytics on your data usage and prepare reports. It is a large repository that stores both structured and unstructured data.

A

Azure Data Lake Storage

84
Q

Azure Data Lake Storage

A

It allows you to perform analytics on your data usage and prepare reports. Data Lake is a large repository that stores both structured and unstructured data.

85
Q

What are the three storage tiers for blob object storage in Azure?

A
  • hot storage tier - for data accessed frequently
  • cool storage tier - for data accessed infrequently and stored for at least 30 days
  • archive storage tier - for data accessed rarely and stored for at least 180 days with flexible latency requirements
