Explanation
Always Encrypted uses two types of keys: column encryption keys and column master keys. A column encryption key is used to encrypt data in an encrypted column. A column master key is a key-protecting key that encrypts one or more column encryption keys.

Explanation
Although the use of system routes facilitates traffic automatically for your deployment, there are cases in which you want to control the routing of packets through a virtual appliance. You can do so by creating user defined routes that specify the next hop for packets flowing to a specific subnet to go to your virtual appliance instead, and enabling IP forwarding for the VM running as the virtual appliance.
Note: User Defined Routes
For most environments you will only need the system routes already defined by Azure. However, you may need to create a route table and add one or more routes in specific cases, such as:
* Force tunneling to the Internet via your on-premises network.
* Use of virtual appliances in your Azure environment.
* In the scenarios above, you will have to create a route table and add user defined routes to it.

Explanation

Box1: Activity log
Azure activity logs provide insight into the operations that were performed on resources in your subscription.
Activity logs were previously known as "audit logs" or "operational logs," because they report control-plane events for your subscriptions.
Activity logs help you determine the "what, who, and when" for write operations (that is, PUT, POST, or DELETE).
Box 2: Logs
Log Integration collects Azure diagnostics from your Windows virtual machines, Azure activity logs, Azure Security Center alerts, and Azure resource provider logs. This integration provides a unified dashboard for all your assets, whether they're on-premises or in the cloud, so that you can aggregate, correlate, analyze, and alert for security events.
