What's the SLA for Azure Maps in terms of guaranteed uptime?
99 percent
99.9 percent
99.99 percent
Answer is 99.9 percent
The SLA for Azure Maps tells you the SLA.
What's the new composite SLA? Remember, the new SLA includes a third virtual machine and Azure Maps.
99.58 percent
99.78 percent
99.99 percent
Answer is 99.58 percent
To compute the composite SLA for a set of services, you multiply the SLA of each individual service.
Adding a third virtual machine reduces the composite SLA. How can companies offset this reduction?
Increase the size of each virtual machine.
Deploy extra instances of the same virtual machines across the different availability zones in the same Azure region.
Do nothing. Using Azure Load Balancer increases the SLA for virtual machines.
Answer is Deploy extra instances of the same virtual machines across the different availability zones in the same Azure region.
If one availability zone is affected, your virtual machine instance in the other availability zone should be unaffected.
What approach might the company take in adding the augmented reality (AR) preview service to its architecture?
The Special Orders app is already in production. The company shouldn't look into the AR service until the service reaches general availability (GA).
The Special Orders app is mainly for use by retail employees. The company can integrate the AR service now because potential downtime or failures aren't an important factor.
The development team can create a prototype version of the app that includes the AR service that it tests out with select retail employees.
Answer is The development team can create a prototype version of the app that includes the AR service that it tests out with select retail employees.
After the AR service reaches general availability (GA), the team can roll it out to production.

When planning to migrate a public website to Azure, you must plan to pay monthly usage costs. This is because Azure uses the pay-as-you-go model.
You attempt to create several managed Microsoft SQL Server instances in an Azure environment and receive a message that you must increase your Azure subscription limits.
What should you do to increase the limits?
Create a service health alert
Upgrade your support plan
Modify an Azure policy
Create a new support request
Answer is Create a new support request
Many Azure resource have quote limits. The purpose of the quota limits is to help you control your Azure costs. However, it is common to require an increase to the default quota.
You can request a quota limit increase by opening a support request. In the support request, select Service and subscription limits (quotas) for the Issue type, select your subscription and the service you want to increase the quota for. For this question, you would select SQL Database Managed Instance as the quote type.

You need to be notified when Microsoft plans to perform maintenance that can affect the resources deployed to an Azure subscription.
What should you use?
Azure Monitor
Azure Service Health
Azure Advisor
Microsoft Trust Center
Answer is Azure Service Health
Azure Service Health provides a personalized view of the health of the Azure services and regions you're using. This is the best place to look for service impacting communications about outages, planned maintenance activities, and other health advisories because the authenticated Service Health experience knows which services and resources you currently use.

Your developers have created 10 web applications that must be host on Azure.
You need to determine which Azure web tier plan to host the web apps. The web tier plan must meet the following requirements:
- The web apps will use custom domains.
- The web apps each require 10 GB of storage.
- The web apps must each run in dedicated compute instances.
- Load balancing between instances must be included.
- Costs must be minimized.
Which web tier plan should you
Standard
Basic
Free
Shared
Answer is Standard
The web apps will use custom domains. (Basic, Shared and standard Support custom domain)
The web apps each require 10 GB of storage. (basic and standard support this)
The web apps must each run in dedicated compute instances.(basic support 3 instance max where standard support 10max)
Load balancing between instances must be included. (free, shared and basic dont support load balancing. standard and above tier only support load balancing/autosacling)
Costs must be minimized. Standard is less costier than premimum and isolated. I hope this is clear to chose the correct answer as STANDARD.
