Question
How many vManage NMSs should be installed in each domain to achieve scalability and redundancy?
Options
- Atwo clusters
- Btwo instances
- Ctwo or more in a cluster
- Dthree or more in a cluster
Explanation
To achieve scalability and redundancy for vManage NMS in a Cisco SD-WAN domain, it is recommended to install three or more instances in a cluster.
Common mistakes.
- A. "two clusters" is incorrect as vManage instances form a single cluster for redundancy and scalability, not multiple clusters.
- B. "two instances" provides some redundancy but may not meet the full scalability and fault tolerance requirements of a robust production environment, particularly for database quorum.
- C. "two or more in a cluster" is less specific than D, and two instances might not provide full quorum in all distributed database scenarios, making three the common minimum for robust clustering.
