A. B. C. D. E.BD.
Based on the given scenario, the engineer has completed the basic installation of two Cisco CMX servers, and is now configuring high availability, but it fails. The task is to identify the root cause of the issue. Let's go through the given options one by one:
A. The Cisco CMX instances are installed in the same subnet. If both Cisco CMX servers are installed in the same subnet, it should not cause an issue with high availability. Cisco CMX high availability requires both servers to be on the same subnet, so this option cannot be the root cause of the problem.
B. The types of the primary and secondary Cisco CMX installations differ. If the primary and secondary Cisco CMX installations differ in type, it can cause an issue with high availability. Both Cisco CMX servers must be of the same type to work with high availability, so this option could be a possible root cause of the issue.
C. The delay between the primary and secondary instance is 200 ms. A delay of 200 ms between the primary and secondary Cisco CMX servers should not cause an issue with high availability. The recommended delay is below 1000 ms, so this option cannot be the root cause of the problem.
D. The sizes of the primary and secondary Cisco CMX installations differ. If the sizes of the primary and secondary Cisco CMX installations differ, it can cause an issue with high availability. Both Cisco CMX servers must have the same configuration to work with high availability, so this option could be a possible root cause of the issue.
E. Both Cisco CMX installations are virtual. It should not cause an issue with high availability if both Cisco CMX installations are virtual. The Cisco CMX can work on both physical and virtual platforms, so this option cannot be the root cause of the problem.
Therefore, the possible root causes of the issue could be options B and D, i.e., the types and sizes of the primary and secondary Cisco CMX installations differ. The engineer should check the types and sizes of both Cisco CMX servers and ensure that they are identical for high availability to work correctly.
