AZ-104: Microsoft Azure Administrator Full Course - Internal Load Balancer

The video tutorial explains the use of internal load balancers within Azure's virtual networks. It covers how these load balancers can be used to distribute database requests to backend SQL servers and describes various load balancing scenarios, including those involving virtual machines and multi-tier applications. The tutorial also discusses the integration of public load balancers with internal ones to create multi-tier applications, emphasizing the security and efficiency of Azure's infrastructure.

What is a key feature of an internal load balancer in a virtual network?

• It only works with public applications.

• It requires additional hardware for operation.

• It allows access to Azure infrastructure via VPN.

• It exposes the front-end IP address to the Internet.

How does an internal load balancer handle database requests?

• It sends all requests to a single SQL server.

• It distributes requests to multiple backend SQL servers.

• It requires manual distribution of requests.

• It blocks requests from virtual machines.

What port number is used by the load balancer to communicate with backend SQL servers?

• 80

• 443

• 1443

• 8080

In what scenario can an internal load balancer be used for multi-tier applications?

• When no load balancing is required.

• When only a single tier is present.

• When backend tiers are not Internet-facing.

• When all tiers are Internet-facing.

What is the role of a public load balancer in a multi-tier application?

• To replace the internal load balancer.

• To expose backend tiers to the Internet.

• To be placed in front of the internal load balancer.

• To eliminate the need for load balancing.
