1. 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 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
B) aline chart showing the line frequency measurements for a second compared to the expected value for the last minute for each distribution site
C) a table showing all of the line frequency measurements for each power distribution point for the last 30 days
D) a bar chart showing the overall average line frequency value for each of the power distribution sites over the last 24 hour period

2. An analyst has been asked to build a rule, alert, and reportlet in Real-time Monitoring (RTM). The rule that triggers the alert fires when: ord_qty>1000. Areportlet should be attached to the alert containing relevant and supplemental information based on the exception information that the rule detected. The view on which the reportlet is based is grouped by product and defines Average_Quantity as: AVERAGE(ord_qty). When attaching the reportlet the analyst created a rule filter based on the data in the data stream. The rule filter is defined as: ord_qty > 3000.When attaching a reportlet to an alert, which two descriptions are true? (Choose two.)

A) The reportlet will never include rows where the Average_Quantity is less than 3000.
B) The reportlet may include a row where an ord_qty column included in the average is between 1000 and 3000.
C) The reportlet will always include a row for the product that was in the event that triggered the alert.
D) The reportlet may be attached without any rows of data.

3. A user is complaining that the Real-time Monitoring objects on their BusinessInsight dashboard appear to have data that is more than 15 minutes old. What are two possible causes for this problem? (Choose two.)

A) The dashboard refresh interval is too high.
B) The polling interval ofthe source JDBC data stream is too infrequent.
C) The widget refresh interval is too high.
D) The lookup table invalidation cache is too frequent.

4. In an event stream, the data stream query returns 100 total rows on the first polling, 200 rows on the second polling, and 50 rows on the third polling. The "Treat all rows in the result set as a single event" property is selected. If a stateless view is created (with all settings set to default) based on this data stream, how many rows will exist in that view after the third polling?

A) 1
B) 350
C) 50
D) 200

5. How can an alertbe fired from the dashboard?

A) Assign a task from a dashboard object and specify a deadline.
B) Go into the alert manager, select an alert, and click the "fire" button.
C) Find a process diagram with a related alert and launch the process.
D) Create a business alert and click to fire it from the dashboard.
