Answer C is incorrect because Azure VPN Gateway is intended to connect Azure networks to remote users or sites when encrypted internet-based connectivity is appropriate, which is a different architectural function.

Answer D is incorrect because Azure public IP address is intended to make a supported Azure service directly reachable from the internet when required, which is a different architectural function.

 

Question 34

For Azure ExpressRoute, which statement is accurate?

  1. Provides private connectivity between on-premises networks and Microsoft cloud services through a connectivity provider.
  2. Provides a managed global transit network for branch, VPN, ExpressRoute, and VNet connectivity.
  3. Is a network interface with a private IP in a VNet that maps to a supported Private Link service.
  4. Connects on-premises sites through Microsoft global network by linking ExpressRoute circuits.

Correct Answer: A

 

Correct Answer

Answer A is correct because Azure ExpressRoute provides private connectivity between on-premises networks and Microsoft cloud services through a connectivity provider.

Incorrect Answers

Answer B is incorrect because that description belongs to Azure Virtual WAN, whose purpose is to simplify large-scale hub-and-spoke and branch connectivity across regions.

Answer C is incorrect because that description belongs to Private endpoint, whose purpose is to provide private IP connectivity to a specific platform service instance.

Answer D is incorrect because that description belongs to ExpressRoute Global Reach, whose purpose is to use ExpressRoute connectivity to provide private site-to-site WAN transit.

 

Question 35

To integrate hybrid DNS without deploying custom DNS forwarder virtual machines, which Azure design option should be selected?

  1. Azure DNS Private Resolver
  2. Azure NAT Gateway
  3. Azure ExpressRoute
  4. Hub-and-spoke topology

Correct Answer: A

 

Correct Answer

Answer A is correct because Azure DNS Private Resolver is designed to integrate hybrid DNS without deploying custom DNS forwarder virtual machines. Azure DNS Private Resolver provides managed inbound and outbound DNS endpoints for recursive name resolution between Azure and on-premises environments.

Incorrect Answers

Answer B is incorrect because Azure NAT Gateway can be useful in Azure architectures, but its primary role is to give private resources reliable outbound internet access without individual public IPs; it is not the best match for the stated priority.

Answer C is incorrect because Azure ExpressRoute can be useful in Azure architectures, but its primary role is to connect enterprise networks to Azure without traversing the public internet; it is not the best match for the stated priority.

Answer D is incorrect because Hub-and-spoke topology can be useful in Azure architectures, but its primary role is to scale network governance and shared connectivity across many application networks; it is not the best match for the stated priority.
