(Correct answers at bottom of test)
1. An operator reports that she is seeing nearly 100 messages an hour from a database server reporting illegal access to a database table. The cause is likely to be some new application software which is still being
3
tested. What could you do to efficiently reduce the number of messages sent by the managed node, but still alert the operator if the problem was continuing?

Please use the following scenario to answer the question below:
A service X has three sub -services, A, B and C. Sub-service A and sub-service B
9
are critical while sub-service C is normal. Service X has no direct messages. Service X has the following status calculation Rule:
30. Why is the status of Service X still Normal?
A. It is still Normal due to a bug in the HP OpenView Service Navigator
Version A.06.00 in the status calculation which was fixed with patch
A.06.01.
B. The threshold value must be 40.0 because a percentage number must be specified if the threshold type is
C. Every service has a virtual message service taking into account the messages associated directly with the service. This means that X really
has 4 sub-services. Consequently 50% of the sub-services are critical and
so the required threshold of 0.6 is not reached.
D. Every service has a virtual message service taking into account the messages associated directly with the service. Messages associated with
a service take absolute precedence over the status of the sub-services
and because there is no message, the status is Normal.

A. Restart the HP OpenView Operations server including the service engine
(opcsv –start).
B. Run database recovery tools.
C. Download selected service logs based on time or service with opcsvcdwn. D. Disable service logging with opcservice –disable logging for all services so

B. are held as compressed files and must be de-compressed after distribution.
C. are held as uncompressed files and must be compressed before
distribution.
D. must be uncompressed using the opcdcode command on the managed node before installation.
33. You select the option “Agent sends alive packets” when configuring a managed node. What happens if the agent fails to send a packet within the specified polling interval?

B. The management server will poll the managed node.
C. The managed node will be marked critical in the management console.
10
D. A message will be generated in the message browser alerting the operator that the managed node is not available.
34. What will be displayed if the “Get Impacted Services” option is executed from a mid-level service?
A. All higher level services are displayed.
B. All services in the entire services tree with a non-normal status will be displayed.
C. Services in higher levels whose status has increased in severity will be
displayed.
D. The entire service tree which includes the selected service will be displayed.
35. How is the “setto” option used in status propagation rules?

“setto” option.
B. The child service is set to the status of the parent service. C. The child service is set to its default status severity.
