300-415 Question #320: Real Exam Question with Answer & Explanation
The correct answer is A: Configure a valid vBond IP on vManage.. If vBond and vManage share certificates and organization names but a control connection is not initiated, configuring a valid vBond IP address on vManage is essential for vManage to discover and connect to vBond.
Controller Deployment
Question
Refer to the exhibit. A vBond controller was added to the controller list with the same Enterprise Root CA certificate as vManage. The two controllers can reach each other via IP/PNO and share the same organization name, but the control connection is not initiated. Which action resolves the issue?
Options
- AConfigure a valid vBond IP on vManage.
- BSynchronize the WAN Edge list on vManage with controllers.
- CConfigure NTP on both controllers to establish a connection.
- DConfigure a valid system IP on the vBond controller.
Explanation
If vBond and vManage share certificates and organization names but a control connection is not initiated, configuring a valid vBond IP address on vManage is essential for vManage to discover and connect to vBond.
Common mistakes.
- B. Synchronizing the WAN Edge list is a subsequent step in the SD-WAN fabric bring-up process, not a prerequisite for the initial control connection between vBond and vManage.
- C. While NTP synchronization is critical for certificate validation and control plane stability, the problem implies a more fundamental communication initiation issue, not a certificate or timing-related error.
- D. A valid system IP is necessary for vBond's identity, but if it is already reachable via IP/PNO, it likely has a system IP; the issue lies with vManage knowing how to use that IP to connect to vBond.
