Question 4

An administrator needs to provide access to an Azure Storage account from an on-premises network connected via ExpressRoute. They are evaluating both Service Endpoints and Private Endpoints. Which of the following is a key advantage of using a Private Endpoint in this scenario?

Accepted Answer

A Private Endpoint enables access from on-premises networks, whereas a Service Endpoint does not.

Answer

A Private Endpoint does not require a private DNS zone for name resolution.

Answer

A Private Endpoint is less expensive to implement than a Service Endpoint.

Answer

A Private Endpoint uses the public IP address of the storage account for enhanced compatibility.

Question 5

When an Azure Private Endpoint is created within a consumer's virtual network, which specific resource is provisioned in that VNet to facilitate the private connection?

Accepted Answer

A network interface (NIC)

Answer

A virtual network gateway

Answer

Question 6

Which of the following statements accurately distinguishes an Azure Private Endpoint from an Azure Service Endpoint?

Accepted Answer

Private Endpoints bring the PaaS service into the VNet with a private IP, while Service Endpoints provide a secure, direct route to the service's public IP over the Azure backbone.

Answer

Service Endpoints bring the PaaS service into the VNet with a private IP, while Private Endpoints secure the route to the service's public IP.

Answer

Private Endpoints support Network Security Groups (NSGs), while Service Endpoints do not.

Answer

Service Endpoints are used to connect to IaaS services, while Private Endpoints are used exclusively for PaaS services.
