Box 1: Key Lookup
The Key Lookup cost is 99% so that is the performance bottleneck.
Box 2: nonclustered index
The key lookup on the clustered index is used because the nonclustered index does not include the required columns to resolve the query. If you add the required columns to the nonclustered index, the key lookup will not be required.

NEW QUESTION # 19
You have an Azure virtual machine named VM1 on a virtual network named VNet1. Outbound traffic from VM1 to the internet is blocked.
You have an Azure SQL database named SqlDb1 on a logical server named SqlSrv1.
You need to implement connectivity between VM1 and SqlDb1 to meet the following requirements:
* Ensure that VM1 cannot connect to any Azure SQL Server other than SqlSrv1.
* Restrict network connectivity to SqlSrv1.
What should you create on VNet1?

A. a service endpoint
B. an ExpressRoute gateway
C. a private link
D. a VPN gateway

Answer: A

Explanation:
Explanation
Azure Private Link enables you to access Azure PaaS Services (for example, Azure Storage and SQL Database) and Azure hosted customer-owned/partner services over a private endpoint in your virtual network.
Traffic between your virtual network and the service travels the Microsoft backbone network. Exposing your service to the public internet is no longer necessary.
