Which deployment method should you use to ensure the router is successfully onboarded and establishes connectivity to the SD-WAN fabric?

A
Use Plug-and-Play (PnP) with a ZTP (Zero Touch Provisioning) server
B
Manually configure the device using CLI and upload the configuration file to vManage
C
Deploy the router in controller-mode and allow automatic synchronization with vSmart
D
Use vManage templates and vBond to push the configuration to the router

Show answer and explanation

Correct answer: A

Explanation

When deploying a new branch router in a Cisco SD-WAN solution, especially in remote locations, Plug-and-Play (PnP) with Zero Touch Provisioning (ZTP) is the most efficient method. This process automates the initial device provisioning and onboarding to the SD-WAN overlay network, leveraging vBond for authentication and vManage for configuration. This eliminates the need for manual configuration and ensures scalability.

A. Correct.
Correct. Plug-and-Play (PnP) with a ZTP server is the recommended approach for onboarding remote sites in SD-WAN, as it minimizes manual intervention and automates the deployment process.
B. Incorrect.
Incorrect. Manually configuring the router at a remote site can be error-prone and does not scale well for Cisco SD-WAN deployments.
C. Incorrect.
Incorrect. Deploying the router in controller-mode is not a valid approach for initial onboarding in the SD-WAN solution.
D. Incorrect.
Incorrect. vManage templates are used for centralized configuration management but require the router to already be onboarded to the SD-WAN fabric.

300-415 Question 102

Select 4

You are deploying Cisco SD-WAN routers at branch offices and need to configure a vEdge router to connect to the SD-WAN fabric. During the deployment, you notice that the router is unable to establish a secure control connection with the vSmart controller. Which of the following steps should you verify to resolve this issue?

A
Ensure the router has a valid and activated Certificate Serial Number (CSN).
B
Check that the router's system IP address matches its configuration in the vManage.
C
Verify that the transport interfaces are properly configured with reachability to the WAN.
D
Confirm that the ZTP process has been bypassed by deploying a manual .p12 certificate.
E
Ensure that the vSmart controller is configured with the same organization name as the router.

Show answer and explanation

Correct answers: A, B, C, E

Explanation

To establish a secure control connection with the vSmart controller, the router must have a valid and activated CSN, a matching system IP address in vManage, properly configured transport interfaces, and the same organization name as the vSmart. These elements are critical for proper authentication, identification, and communication within the SD-WAN fabric. Verifying these items ensures that the router can join the SD-WAN fabric successfully.

A. Correct.
A valid and activated Certificate Serial Number (CSN) is required for the router to authenticate with the SD-WAN fabric.
B. Correct.
The system IP address must match the configuration in vManage to ensure proper identification and control connection establishment.
C. Correct.
Transport interfaces need to be correctly configured and have WAN reachability for the router to communicate with controllers.
D. Incorrect.
Bypassing the ZTP process is not mandatory and is only needed in specific deployment scenarios. This step is not required to resolve the issue described.
E. Correct.
The organization name must match across all devices, including vSmart and vEdge, to ensure secure and successful control connections.

300-415 Question 103

Single answer

You are tasked with deploying an SD-WAN router at a branch office. The branch office has dual Internet Service Providers (ISPs) for redundancy. The design requires both links to be active and used for traffic. Which deployment method should you choose to ensure both links are utilized efficiently and dynamically adjusted based on performance metrics?

A
Single TLOC with Dual ISP connections
B
Dual TLOCs with Static Routes
C
Dual TLOCs with Dynamic Path Selection
D
Single TLOC with Load Balancing

Show answer and explanation

Correct answer: C

Explanation

In SD-WAN, Dual TLOCs with Dynamic Path Selection is the ideal deployment method when you need to actively utilize both ISP links while dynamically adjusting traffic based on real-time performance metrics. This ensures optimal use of available bandwidth, improved redundancy, and application performance.

A. Incorrect.
Single TLOC with Dual ISP connections does not fully utilize both links dynamically. It typically assigns a single tunnel per TLOC, limiting the ability to balance traffic across ISPs dynamically.
B. Incorrect.
Dual TLOCs with Static Routes uses static routing, which does not provide dynamic adjustments based on link performance. This is not suitable for ensuring efficient utilization of both links.
C. Correct.
Dual TLOCs with Dynamic Path Selection leverages SD-WAN's ability to dynamically route traffic based on real-time performance metrics, ensuring both links are actively used and optimized.
D. Incorrect.
Single TLOC with Load Balancing does not provide the flexibility and redundancy of dual TLOCs, and it may not dynamically adjust traffic based on link performance.

300-415 Question 104

Single answer

An enterprise is deploying Cisco SD-WAN routers at multiple branch locations. The IT team wants to ensure that all new branch routers are onboarded securely and automatically using a minimal configuration. Which deployment method should the IT team prioritize for this scenario?

A
Manual configuration using CLI on each router
B
Plug and Play (PnP) with Cisco vManage
C
Bootstrap configuration using a USB drive
D
Zero-Touch Provisioning (ZTP) with Cisco vManage

Show answer and explanation

Correct answer: D

Explanation

Zero-Touch Provisioning (ZTP) with Cisco vManage is the ideal deployment method for Cisco SD-WAN routers in large-scale environments. It streamlines the process by automatically onboarding routers to the SD-WAN fabric without requiring local configuration. This approach reduces manual effort, ensures security during deployment, and scales well for multiple branch locations.

A. Incorrect.
Manual configuration using CLI requires a significant amount of manual effort and does not provide a secure or automated onboarding method for multiple routers.
B. Incorrect.
Plug and Play (PnP) is a valid onboarding method, but it is typically used in scenarios involving Cisco PnP-enabled devices and specific workflows. It is not the preferred method for large-scale SD-WAN deployments.
C. Incorrect.
Bootstrap configuration using a USB drive can be used, but it requires physical access to each router, which may not align with the goal of secure and automated deployment.
D. Correct.
Zero-Touch Provisioning (ZTP) with Cisco vManage is the recommended method for onboarding SD-WAN routers securely and automatically with minimal configuration. It allows the routers to connect to the SD-WAN fabric and retrieve their configuration without manual intervention.

300-415 Question 105

Single answer

An enterprise is deploying Cisco SD-WAN and has decided to use a hybrid WAN architecture with both MPLS and broadband internet connections. The IT team wants to ensure secure and scalable connectivity across branch offices while maintaining redundancy. Which WAN Edge deployment option would best suit this requirement?

A
Single WAN Edge device in each branch office with MPLS as the primary link and broadband as backup
B
Dual WAN Edge devices in each branch office, each connected to both MPLS and broadband links
C
Single WAN Edge device in each branch office with only broadband internet as the transport
D
Dual WAN Edge devices in each branch office, each connected to a single transport link (one to MPLS, one to broadband)

Show answer and explanation

Correct answer: B

Explanation

In a hybrid WAN deployment, using dual WAN Edge devices at each branch office with both MPLS and broadband connections ensures redundancy, scalability, and transport flexibility. This setup supports load balancing, failover, and secure connectivity across different transport types, meeting the enterprise's requirements effectively.

A. Incorrect.
This option does not provide sufficient redundancy or scalability, as a single WAN Edge device creates a single point of failure and limits the ability to actively use both transport links for load balancing or failover.
B. Correct.
This option is the best choice for redundancy and scalability. By having dual WAN Edge devices, each connected to both MPLS and broadband, the solution ensures high availability, load balancing, and transport independence. It also avoids single points of failure.
C. Incorrect.
This option sacrifices redundancy and scalability by relying on a single WAN Edge device and a single transport type, which does not align with the requirements for secure and scalable connectivity.
D. Incorrect.
While this option provides redundancy at the device level, it lacks flexibility and scalability because each WAN Edge device is limited to a single transport, preventing efficient use of both links for load balancing or failover.
