Cisco® 300-415 Exam Practice Questions (P. 2)

GPT-4o - Answer

The correct answer is indeed vBond. This component sits within the orchestration plane of Cisco's SD-WAN architecture and performs critical initial roles such as authenticating WAN Edge devices, aiding in their Zero-Touch Provisioning, distributing control and management plane details, and simplifying Network Address Translation (NAT) traversal challenges. This is essential for establishing secure and efficient communication between WAN Edge devices and vSmart controllers.

GPT-4o - Answer

In Cisco SD-WAN, the Cloud OnRamp feature facilitates the automatic provisioning of WAN Edge routers in cloud environments like AWS. It extends enterprise WAN capabilities into public clouds, streamlining the integration and management of cloud resources with the enterprise network. This enables a smoother deployment and operation of WAN services over cloud infrastructures.

GPT-4o - Answer

The optimal method for extending a Cisco SD-WAN to AWS involves using Cloud OnRamp for IaaS. Through this service, vManage automates the deployment of virtual SD-WAN routers within a transit VPC in AWS, effectively creating virtual WAN Edge devices. This integration simplifies connectivity and management between branch networks and cloud resources, enhancing network efficiency and reliability directly through AWS.

GPT-4o - Answer

The correct choice, 'Integration with PaaS providers,' aligns with Cisco SD-WAN's capabilities to optimize cloud software deployments, crucial for enhancing application performance—a primary concern for the bank. Furthermore, this feature aids in reducing overhead by simplifying cloud integration and management, thereby indirectly benefiting compliance and security tasks. While 'QoS and application prioritization' (Option B) is a valid feature, it primarily focuses on traffic management rather than directly enhancing cloud application experiences or simplifying security processes.

GPT-4o - Answer

Correct; ensuring the Cisco SD-WAN Edge router AMIs are subscribed to within your AWS account is essential as it allows for the deployment of the Cisco SD-WAN Edge routers in AWS. This step explicitly correlates with setting up the Cisco Cloud onRamp for IaaS. Furthermore, configuring a device template specifically for Cloud WAN Edge deployment and attaching it to the appropriate instances in the AWS is crucial. This setup is key as it predefines the configurations and settings required for the Edge routers to operate correctly in a cloud environment, facilitating their deployment and integration within AWS infrastructures.

GPT-4o - Answer

The vSmart Controller is indeed the key component in the Cisco SD-WAN architecture that takes on the responsibility of distributing route and policy information through the Overlay Management Protocol (OMP). This centralized approach not only enhances the management of data traffic and network routes but also simplifies policy enforcement across the network, significantly streamlining operations and increasing efficiency. Remember, it acts like the brain of the operation, ensuring that every part of your network is synced up and adhering to the rules set within your policies.

GPT-4o - Answer

For enhancing data plane resiliency in Cisco SD-WAN, Bidirectional Forwarding Detection (BFD) is used to proactively monitor the availability and responsiveness of network paths. This protocol's primary role is to quickly identify faults within the network, thereby mitigating downtime by enabling faster failover to alternative paths. BFD operates directly over IPsec tunnels between routers, which is pivotal in maintaining the reliability and performance of the SD-WAN network.
