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: Yes - SLA's vary based on the resource type and the location distribution of the resource. However, the minimum uptime for all Azure services is 99.9 percent.
Box 2: Yes - The SLA guaranteed uptime is increased (usually to 99.95 percent) when resources are deployed across multiple regions.
Box 3: No - The number of subscriptions is unrelated to uptime SLA's. You can deploy resources to multiple regions under a single subscription or you can have multiple subscriptions with resources deployed to the same region. Reference: https://azure.microsoft.com/en-us/support/legal/sla/summary/
1) Yes - minimum guaranteed is 99.9%
2) Yes - Multiple AZ give you fault tolerance, Multiple regions give you Disaster Recovery. Should a whole region fail, it would take much longer to wait for it to come back, or redeploy everything in a new region, than already having the resources/services in said different region. Therefore, having services/resources span across multiple region CAN increase SLA (decrease downtime)
3) No - SLAs are for services, not subscriptions
1st is No:
We guarantee that at least 99% of the Apache Spark sessions will be created successfully."
and "We guarantee that at least 99.9% (99% for Cool Access Tier) of the time, we will successfully process requests to read data from Locally Redundant Storage (LRS), Zone Redundant Storage (ZRS), and Geo Redundant Storage (GRS) Accounts.
We guarantee that at least 99.9% (99% for Cool Access Tier) of the time, we will successfully process requests to write data to Locally Redundant Storage (LRS), Zone Redundant Storage (ZRS), and Geo Redundant Storage (GRS) Accounts and Read Access-Geo Redundant Storage (RA-GRS) Accounts." from the same link:

The SLA refers basically to Service Uptime. You mention others metrics than uptime (time to process requests, to access, etc)..I know the question wording is confusing...
2nd question is NO. "Availability Zones are physically separate locations within an Azure region". Availability zones is only used for fault-tolernace in the same region not across diferent regions
Uptime means your services are up and running as if nothing happened...your users may not even realize there was failure at all. AZ in the same region provides this. But disaster recovery is a whole different beast. That would take much longer downtime. So, the answer is NO.
2. You’ve nailed it! Multiple Availability Zones (AZs) indeed provide fault tolerance by ensuring high availability within the same region. If an AZ experiences downtime, the other AZs in the same region can maintain service continuity.
On the other hand, multiple regions are essential for Disaster Recovery (DR). In the rare case where an entire region fails (e.g., due to a natural disaster), having resources already deployed in a secondary region ensures much faster recovery. This proactive approach avoids the significant delay associated with redeployment and data restoration in a new region.
By architecting systems to span multiple regions, you're effectively designing for resilience on a much larger scale. This strategy minimizes downtime and can indeed enhance your SLA (Service Level Agreement) by reducing the time to recover critical services.

First no
We guarantee that API Management Service instances running in the Consumption Tier, Basic Tier, Standard Tier, and Premium Tier deployments scaled within a single region will respond to requests to perform operations at least 99.95% of the time.
2dn question is NO.
If you need to improve the SAL to guarantee 99.99% availability, you must install an additional instance in a Different Availability Zone in the same Region.
