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 don't know, guys. All this talk about VRFs and OMP advertisements is making my head spin. I'm just going to close my eyes and point at the answer. *pokes A)* There, problem solved!

D) Disable bgp advertisement? That can't be right, the question is asking how to enable the OMP advertisement, not disable it. A) is the clear winner here.

C) Enter sdwan mode? Really? That sounds like it's completely unrelated to the task at hand. I'm going with A) for sure.

I was leaning towards B) Enable bgp advertisement, but then I realized that's a bit too generic. The question is asking about a specific VRF instance, so A) is probably the right choice.

I'm not sure, but I think option A makes sense because it would ensure that only the routes from that specific VRF are advertised.

I agree with Bettina, because enabling OMP advertisement for BGP routes in a specific VRF requires configuring VRF-specific route advertisements.
