You manage a set of virtual machines (VMs) deployed to the cloud service named fabrikamVM.
You configure auto scaling according to the following parameters:
-> With an instance range of two to six instances
-> To maintain CPU usage between 70 and 80 percent to scale up one instance at a time
-> With a scale up wait time of 30 minutes
-> To scale down one instance at a time
-> With a scale down wait time of 30 minutes
You discover the following usage pattern of a specific application:
-> The application peaks very quickly, and the peak lasts for several hours.
-> CPU usage stays above 90 percent for the first 1 to 1.5 hours after usage increases.
-> After 1.5 hours, the CPU usage falls to about 75 percent until application usage begins to decline.
You need to modify the auto scaling configuration to scale up faster when usage peaks.
What are two possible ways to achieve this goal? Each correct answer presents a complete solution.
Decrease the scale down wait time.
Decrease the scale up wait time.
Increase the number of scale up instances.
Increase the scale up wait time.
Increase the maximum number of instances.

You administer a Microsoft Azure SQL Database data base in the US Central region named contosodb. Contosodb runs on a Standard tier within the S1 performance level.
You have multiple business-critical applications that use contosodb.
You need to ensure that you can bring contosodb back online in the event of a natural disaster in the US Central region. You want to achieve this goal with the least amount of downtime.
Which two actions should you perform? Each correct answer presents part of the solution.
Upgrade to S2 performance level.
Use active geo-replication.
Use automated Export.
Upgrade to Premium tier.
Use point in time restore.
Downgrade to Basic tier.
Answer: B,D Explanation:
B: The Active Geo-Replication feature implements a mechanism to provide database redundancy within the same Microsoft Azure region or in different regions (geo- redundancy).
One of the primary benefits of Active Geo-Replication is that it provides a database-level disaster recovery solution. Using Active Geo-Replication, you can configure a user database in the Premium service tier to replicate transactions to databases on different Microsoft Azure SQL Database servers within the same or different regions. Cross-region redundancy enables applications to recover from a permanent loss of a datacenter caused by natural disasters, catastrophic human errors, or malicious acts.
D: Active Geo-Replication is available for databases in the Premium service tier only.
