, Question 1
In a utility's enterprise data warehouse, the 'Customer Master' dimension is
slowly changing, and a rate analyst needs to reproduce a billing calculation
exactly as it was two years ago. Which SCD Type best preserves historical
accuracy while avoiding excessive row proliferation for attribute changes that
are not analytically relevant?
A. Type 1
B. Type 2
C. Type 3
D. Type 6
Correct Answer: D - Type 6
RATIONALE
Type 6 hybrid combines Type 1 (current value overwrite), Type 2
(history rows), and Type 3 (previous value column) to provide both
historical accuracy and current-state efficiency. Type 1 loses history;
Type 2 alone can proliferate rows for trivial changes; Type 3 tracks
only one prior value. Type 6 is the best fit for selective historical
tracking.
Question 2
A SCADA historian stores 50,000 tags at 1-second resolution. To reduce
storage cost while preserving event fidelity for regulatory audits, which
combination of techniques is most appropriate?
A. Downsample to 1-minute averages and store in a relational DB
B. Apply deadband compression and store exceptions in a columnar
time-series database
C. Archive raw data to tape and keep only daily summaries online
D. Use round-robin flat files with periodic full backups
Correct Answer: B - Apply deadband compression and store
exceptions in a columnar time-series database
Page 2
, RATIONALE
Deadband compression (e.g., swinging door) removes redundant
steady-state samples while preserving significant changes, and
columnar time-series databases (e.g., OSIsoft PI, TimescaleDB) are
optimized for high-ingest, high-compression storage. Averaging loses
event detail; tape archiving impairs audit access; flat files lack query
performance and integrity.
Question 3
A systems analyst must integrate a legacy CIS with a new MDM platform
using an enterprise service bus. The CIS uses batch nightly extracts, while
MDM requires near-real-time updates. Which integration pattern best balances
timeliness with minimal disruption to the legacy system?
A. Direct database triggers on the CIS
B. Change data capture (CDC) with a message queue
C. Full table replication every 15 minutes
D. File transfer protocol (FTP) of CSV extracts
Correct Answer: B - Change data capture (CDC) with a message
queue
RATIONALE
CDC reads the database transaction log to capture changes with
minimal impact and streams them via a message queue for
near-real-time delivery. Database triggers add overhead and risk to the
legacy system; frequent full replication is resource-intensive; FTP
CSV is batch-oriented and not near-real-time.
Question 4
A GIS analyst needs to determine which customers are within 500 feet of a
planned underground cable route. The customer layer is a point feature class,
and the route is a line feature class. Which geoprocessing operation is most
appropriate?
Page 3
, A. Buffer the route and perform a spatial join with customers
B. Intersect the route with the customer layer
C. Use a Near analysis to calculate distances
D. Convert the route to points and use a point distance tool
Correct Answer: A - Buffer the route and perform a spatial join
with customers
RATIONALE
Buffering the line creates a polygon representing the 500-ft corridor,
and a spatial join selects points within that polygon. Intersect works
on polygon/line overlaps, not point selection; Near gives distances but
does not select; converting to points loses the linear corridor.
Question 5
A utility is designing a rate structure to recover fixed costs while encouraging
conservation. Which rate design best aligns with cost-of-service principles and
modern regulatory trends?
A. Flat volumetric rate
B. Inclining block rate with a fixed charge
C. Declining block rate
D. Time-of-use rate with no fixed charge
Correct Answer: B - Inclining block rate with a fixed charge
RATIONALE
An inclining block rate with a fixed charge recovers fixed costs
through the fixed component and promotes conservation via higher
prices for higher usage, aligning with cost-of-service and modern
regulatory preferences. Flat rates do not encourage conservation;
declining blocks discourage it; TOU without fixed charge
under-recovers fixed costs.
