Question #: 13
Topic #: 4
[All 300-440 Questions]

A company has multiple branch offices across different geographic locations and a centralized data center. The company plans to migrate Its critical business applications to the public cloud infrastructure that is hosted in Microsoft Azure. The company requires high availability, redundancy, and low latency for its business applications. Which connectivity model meets these requirements?

Show Suggested Answer Hide Answer
Suggested Answer: A

The connectivity model that meets the requirements of high availability, redundancy, and low latency for the company's business applications isExpressRoute with private peering using SDCI.

ExpressRoute is a service that provides a dedicated, private, and high-bandwidth connection between the customer's on-premises network and Microsoft Azure cloud network1.

Private peering is a type of ExpressRoute circuit that allows the customer to access Azure services that are hosted in a virtual network, such as virtual machines, storage, and databases2.

SDCI (Secure Data Center Interconnect) is a Cisco solution that enables secure and scalable connectivity between multiple data centers and cloud providers, using technologies such as MPLS, IPsec, and SD-WAN3.

By using ExpressRoute with private peering and SDCI, the company can achieve the following benefits:

High availability: ExpressRoute circuits are redundant and resilient, and can be configured with multiple service providers and locations for failover and load balancing1.SDCI also provides high availability by using dynamic routing protocols and encryption mechanisms to ensure optimal and secure path selection3.

Redundancy: ExpressRoute circuits can be paired together to form a redundant connection between the customer's network and Azure4.SDCI also supports redundancy by allowing multiple connections between data centers and cloud providers, using different transport technologies and service levels3.

Low latency: ExpressRoute circuits offer lower latency than public internet connections, as they bypass the congestion and variability of the internet1.SDCI also reduces latency by using MPLS and SD-WAN to optimize the performance and quality of service for the traffic between data centers and cloud providers3.

I feel like I'm missing something. Why would we even consider a site-to-site VPN? Isn't that, like, so 2010? Let's go with the future-proof option, ExpressRoute all the way!

Definitely, site-to-site VPN seems outdated compared to the other options. ExpressRoute is the future-proof choice.

AWS Direct Connect? Are you kidding me? This is a Microsoft Azure migration, not an AWS one. Gotta stay focused here, folks.

Hmm, I'm not sure ExpressRoute is the best choice. Isn't it a bit pricey? I'd prefer something more cost-effective, like a site-to-site VPN with Azure VPN gateway.

I'm leaning towards hybrid connectivity with SD-WAN. It's a more flexible and scalable solution, and it can still deliver the performance we're after.

I see your point, but I think AWS Direct Connect with dedicated connections might offer the redundancy we are looking for in this scenario.
