HOTSPOT - For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Hot Area:
Suggested Answer:
Box 1: No - Not all Azure regions support availability zones.
Box 2: No - Regions that support availability zones support Linux virtual machines.
Box 3: Yes - Availability Zones is a high-availability offering that protects your applications and data from datacenter failures. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there's a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures. Zone-redundant services replicate your applications and data across Availability Zones to protect from single-points-of-failure. With Availability Zones, Azure offers industry best 99.99% VM uptime SLA. References: https://docs.microsoft.com/en-gb/azure/availability-zones/az-overview
NO-NO-NO
1-Not every region has multiple Availability Zone. Some regions may have only one Availability Zone.
2-One can run both Linux and Windows virtual machines created in the availability zone.
3-Availability zones are used to replicate data and applications in the same region.
agree with answer. but could you please further elaborate the explanation of 1st question? there is no way for us to make availability zones. doesn't matter how many AZs per region.
It is a Microsoft's choice
some areas have it, others don't

See ALTERNATE REGIONS. It's not about having one or multiple AZ. It's just that some regions dont support the concept.

All Enabled Regions have a minimum of 3 AZ zones. Therefore the answer is YES-NO-NO
FIRST ANSWER IS NO ! Don't mislead people. Some regions do not support Availability Zones. https://docs.microsoft.com/en-us/azure/availability-zones/glossary
It exists RECOMMENDE regions AND ALTERNATE Regions. Alternate regions does not support AZ.
A region that extends Azure's footprint within a data-residency boundary where a recommended region also exists. Alternate regions help to optimize latency and provide a second region for disaster recovery needs. They aren't designed to support availability zones, although Azure conducts regular assessment of these regions to determine if they should become recommended regions. These regions are designated in the Azure portal as Other.
Ex: EUROPE UK WEST

No: Clear explanations already provided.
No: Clear explanation is also provided.
No: For number 3, Availability zones are used to replicate data and applications within the same AZ region (not to MULTIPLE regions as the question suggests).
MS has mentioned in their lecture/module on availability zone - Availability Zones -------------
Important -
To ensure resiliency, a minimum of three separate availability zones are present in all availability zone-enabled regions. However, not all Azure Regions currently support
availability zones.
1. NO, not all regions are "availability zone - enabled regions". This service is limited.
2. NO.
3. NO. Availability zone service is available at regional level whereas Geo-Redunancy is avaliable at regional level.

Not all Regions have Availability Zones. Regions that support Availability Zones have a minimum of three separate zones to ensure resiliency.
so 1st is No
