Test Tips-1 Flashcards
What considerations should you keep in mind when choosing a region for deploying resources on Azure?
When choosing a region, consider factors like geographical location, available features, and pricing.
What are Azure regions, and what do they consist of?
Azure regions are globally distributed groups of data centers located around the world, except for regions with single data centers without availability zones. Each region consists of several nearby data centers or a single data center for regions without availability zones.
What is the purpose of region pairs in Azure?
Region pairs act as redundancy or failover locations. Each region is paired with another region in the same country, except for Brazil. If one region becomes unavailable, resources in the paired region can take over.
What are sovereign regions in Azure?
Sovereign regions are separate and isolated from the general Azure public cloud. They cater to various levels of government compliance. The two sovereign region types are Azure for US government and Azure China.
What is the primary purpose of availability zones in Azure?
Availability zones provide fault isolation within regions by offering multiple independent data centers. They enhance redundancy and high availability by ensuring that if one data center becomes unavailable, others can take over the load.
What are zonal and zone-redundant services in the context of availability zones?
Zonal services allow you to choose the specific availability zone for deployment (e.g., virtual machines). Zone-redundant services automatically replicate data across zones for redundancy (e.g., Azure storage).
What are the main layers of resource organization in Azure, from bottom to top?
The main layers are resources, resource groups, subscriptions, and management groups.
What is the purpose of resource groups in Azure?
Resource groups are used to organize resources with similar access or lifecycle needs. They act as a management and access control boundary.
How do subscriptions differ from resource groups in Azure?
Subscriptions serve as both a billing and access control boundary. They contain multiple resource groups and define the payment method for Azure resources.
What is the role of management groups in Azure’s resource organization?
Management groups provide centralized management for multiple subscriptions. They help in organizing and applying policies across various subscription levels.
Explain the concept of resource hierarchy in Azure.
Resource hierarchy describes the top-down application of access and policies. Child objects inherit access and policies from parent layers, ensuring consistent management and policy application.
Give an example of how access roles or policies are inherited in resource hierarchy.
An access role or policy applied at the subscription level automatically applies to all included resource groups and resources within those resource groups.
