This output was captured on a Cisco IOS gateway shortly after it became the active Cisco Unified Border

Element in a box-to-box redundancy failover.

How many calls are native to this Cisco Unified Border Element?

  1. 9

  2. 12

  3. 19

  4. 31

  5. 40

Answer: D Explanation:

To check for native and nonnative (preserved) calls when both are present The numbers of calls on the system are shown as follows:

Total number of calls = quot;Number of calls in HA DBquot; quot;Number of calls in HA sync pending DBquot;.

Total number of preserved (nonnative) calls = quot;Number of calls in HA preserved session DBquot;.

Total number of native calls (calls set up since the failover and therefore not preserved over the failover) is the difference in the previous two numbers. In this example, it is (28 12) – 9 = 31.
