Answer is C - ExpressRoute provides secure connection over a private network between the on-premises network and the Azure virtual networks

VPN is over public internet, ExpressRoute over private.

Answer is C as per https://www.examtopics.com/discussions/microsoft/view/18330-exam-az-301-topic-6-question-22-discussion/

Over Private Connection...... High availability... both are present on "Express Route"

Correct Answer: ExpressRoute. ExpressRoute allows connections between on-premises networks and Azure virtual networks.

Private access needs C

Answer should be C

I would say C： https://docs.microsoft.com/en-us/azure/expressroute/expressroute-faqs#are-connections-to-expressroute-redundant Are connections to ExpressRoute redundant? Yes. Each ExpressRoute circuit has a redundant pair of cross connections configured to provide high availability.

"secure connection over a private network" Answer is C for sure; ExpressRoute

I understand ExpressRoute provides a redundant pair of cross connections configured to provide high availability. Example is https://docs.microsoft.com/en-us/azure/expressroute/designing-for-high-availability-with-expressroute#architecture-considerations But VPN also provide a solution to archive this goal with below design. Why doesn't this VPN design meet the requirement? Dual-redundancy: active-active VPN gateways for both Azure and on-premises networks ref: https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-highlyavailable#dual-redundancy-active-active-vpn-gateways-for-both-azure-and-on-premises-networks

C. ExpressRoute

The link and key reason given by ravy_rv proves undoubtedly the answer is Expressroute ExpressRoute circuit has a redundant pair of cross connections configured to provide high availability

Question is asking for pair of cross connections which is Express Route not VPN.

I initially thought vpn but it’s express route. VPN goes over public network, express route is over private network. Although express route isn’t encrypted it’s still secure.

Key here is "cross connections", which has a specific meaning in networking and is mentioned in express route capabilities in the numerous links posted here

The requirement is not high-throughput. Also ExpressRoute is Private connection but not secure. VPN Gateway is.

Its listed as ExpressRoute on the 301 examtopic https://www.examtopics.com/discussions/microsoft/view/18330-exam-az-301-topic-6-question-22-discussion/
