IBM Cognos Real-time Monitoring Developer Sample Questions:

1. A customer's database, which is used as a source for a lookup table, is modified on a regular basis causing the data to become invalid within five minutes. The databasecontains 5,000,000 rows and is indexed on the field to be joined on and optimized for reading. How should the caching settings be configured for this lookup table?

A) Enable caching with a setting of "20" in the "Number of results to cache" field.
B) Enable Caching with a setting of "20" in the "Number of results to cache" field, set an invalidation schedule for every five minutes, and enable prefetch.
C) Disable caching.
D) Enable caching with a setting of "20" in the "Number of results to cache" field and set an invalidation schedule for every five minutes.

2. A customer has an order entry system that adds new records periodically throughout the day. The data stream should process only those new records which have been added since the previous polling cycle. These new records should augment previously processed records. How would you configure the "Incrementing Field" and the "Clear State" properties?

A) Set the "Incrementing Field" to be a timestamp field that contains values which may be smaller than a previously processed value and set the "Clear State" to "Do Not Clear State".
B) Set the "Incrementing Field" to be an integer field that contains valueswhich are constantly increasing and set the "Clear State" to "Do Not Clear State".
C) Set the "Incrementing Field" to be an integer field that contains values which may be smaller thana previously processed value and set the "Clear State" to "Do Not Clear State".
D) Set the "Incrementing Field" to be a timestamp field that contains values which are constantly increasing and set the "Clear State" to "Always clear state for new data".

3. Which two statements about a public watch point are true? (Choosetwo.)

A) You cannot change the availability of a watch point after you have saved it.
B) Public watch points are visible to all users.
C) An e-mail notification can be sent from a public watch point.
D) By default, watch points are public.

4. A retail customer must be able to analyze sales of various products as they happen. Users will view metrics for the number of units soldevery five minutes by region, by product type, and by time increment. At times, the users will need to drill into a specific five minute time increment to see all the details of each transaction that makes up the unit count (for a specific region/type). Transactions are populated into five distinct regional databases from the retail outlets. Regarding Real-time Monitoring, which statement is correct?

A) RTM can provide all the requirements except the aggregation of data from the five sources.
B) RTM can provide all the requirements without any new infrastructure.
C) RTM can provide all the requirements, but would require a centralized data store of all transaction-level detail.
D) RTM can aggregate unit counts across the various dimensions, but not provide the detailed transactions when drilled upon.

5. Since electric delivery companies are required to maintain line frequency within a very narrow tolerance (< 0.1%) and to rapidly implement corrective action to repair out-ofbounds conditions, Real-time Monitoring (RTM) has been deployed to monitor line frequency measurements that are retrieved from key power distribution points every second. Which two metrics are appropriate for an RTM dashboard object where the data is refreshed every five seconds? (Choose two.)

A) a table showing all of the line frequency measurements for each power distribution point for the last 30 days
B) a bar chart showing the number of individual line frequency measurements that exceeded the defined tolerance grouped into 15 minute intervals for the last 24 hours
C) a bar chart showing the overall average line frequency value for each of the power distribution sites over the last 24 hour period
D) aline chart showing the line frequency measurements for a second compared to the expected value for the last minute for each distribution site
