300-415 Question 85
Select 3You are tasked with deploying Cisco SD-WAN controllers in a private data center. Which of the following prerequisites must be fulfilled to successfully install these controllers?
- A
Generate and upload the root CA certificate before bringing up the controllers.
- B
Ensure that each controller has the required minimum CPU, memory, and disk resources.
- C
Configure the controllers with a static IP address or a DHCP-assigned IP address.
- D
Enable NAT on the controllers’ interfaces to allow internal communication.
- E
Verify connectivity between vManage, vSmart, and vBond controllers.
Show answer and explanation
Correct answers: A, B, E
Explanation
During Cisco SD-WAN controller installation, it is crucial to prepare the environment by meeting prerequisites like uploading the root CA certificate, ensuring sufficient hardware resources, and confirming connectivity between controllers. These steps ensure proper deployment and functionality of the SD-WAN solution.
- A. Correct.
Generating and uploading the root CA certificate is a critical step to ensure the controllers can authenticate and establish secure connections.
- B. Correct.
Each controller requires adequate CPU, memory, and disk resources to function properly; failing to meet these requirements can lead to deployment issues.
- C. Incorrect.
While static or DHCP-assigned IP addresses are valid for some devices, it is not a specific prerequisite for installing the controllers.
- D. Incorrect.
Enabling NAT is not a requirement for SD-WAN controller installation. NAT is typically configured for traffic traversing public networks, not for controller communication.
- E. Correct.
Connectivity between vManage, vSmart, and vBond controllers is essential for the SD-WAN solution to operate correctly.
