A network engineer is troubleshooting a newly configured IPsec VPN tunnel between an on-premises Cisco IOS XE router and an Azure VPN Gateway. The tunnel fails to establish. The engineer runs the command `show crypto isakmp sa` and sees the tunnel state as `MM_NO_STATE`. What is the most likely cause of this issue?
An organization is deploying Cisco SD-WAN and wants to optimize Microsoft 365 performance for its branch offices using Cloud OnRamp for SaaS. The goal is to send Microsoft Teams traffic directly to the internet over the best-performing path, while all other Microsoft 365 traffic is backhauled to a regional data center for inspection. Which two policy types must be configured in vManage to achieve this? (Select TWO)
A global enterprise with data centers in multiple continents needs to establish private, low-latency connectivity to several VPCs in AWS and VNETs in Azure. The CISO has mandated that traffic must not traverse the public internet. The solution must be scalable to add new cloud regions and providers with minimal effort. Which architecture model best fits these requirements?
True or False: When using Cisco SD-WAN to connect to a SaaS provider like Salesforce, the Cloud OnRamp for SaaS feature primarily relies on BGP for path selection to the SaaS application front door.
A network administrator is configuring a route-based IPsec VPN from a Cisco IOS XE router to a Google Cloud VPN endpoint. BGP will be used to exchange routes. Which configuration snippet is essential for enabling BGP to run over the tunnel interface?
A company has deployed a Cisco SD-WAN fabric and is using vManage to monitor connectivity. An administrator notices that a vEdge router at a branch site has lost connectivity to one of its two available transports (MPLS). In the vManage dashboard, what visual indicator represents this loss of connectivity for the specific transport?
An architect is designing a network for a government agency that requires connectivity to AWS GovCloud. The solution must adhere to FEDRAMP High standards. Which connectivity model and security feature are most appropriate to meet these strict compliance requirements?
A retail company is migrating its e-commerce platform to a multi-cloud architecture using both AWS and Azure. The on-premises data center hosts the primary inventory database. The company requires a connectivity solution that provides high availability, consistent low latency for database synchronization, and the ability to dynamically route traffic between the on-premises environment and both clouds. The current on-premises network is built on Cisco routers. The IT team is small, so a solution that simplifies routing management is preferred. The average bandwidth requirement is 2 Gbps, with peaks up to 5 Gbps during sales events. The CIO has mandated that a single provider failure should not cause a complete outage of cloud connectivity. What is the most suitable design recommendation?
What is the primary function of a Cisco SD-WAN vBond Orchestrator in the control plane?
