Question 1
Several different issues need to be distinguished. Which answer identifies their topics in the
order shown?
1. Chemical safety regarding battery storage and electrolyte handling
2. Series and parallel circuit configurations, voltage, current, and power relationships

A. 1: Safety (20%); 2: Safety (20%)
B. 1: Safety (20%); 2: Core Knowledge (30%)
C. 1: Core Knowledge (30%); 2: Safety (20%)
D. 1: Core Knowledge (30%); 2: Core Knowledge (30%)

Correct Answer: B
Full Explanation: The correct associations are 1 with Safety (20%) (Chemical safety regarding
battery storage and electrolyte handling); 2 with Core Knowledge (30%) (Series and parallel
circuit configurations, voltage, current, and power relationships). Exchanging these topics
changes the subject of one or more concerns rather than preserving their distinct meanings.



Question 2
Several different issues need to be distinguished. Which answer identifies their topics in the
order shown?
1. Structural Infrastructure Assessment
2. Module cleaning methods, schedules, and water quality considerations

A. 1: Operations & Maintenance (21.7%); 2: Operations & Maintenance (21.7%)
B. 1: Existing System Infrastructure Considerations (28.3%); 2: Existing System Infrastructure
Considerations (28.3%)
C. 1: Operations & Maintenance (21.7%); 2: Existing System Infrastructure Considerations
(28.3%)
D. 1: Existing System Infrastructure Considerations (28.3%); 2: Operations & Maintenance
(21.7%)

Correct Answer: D
Full Explanation: The correct associations are 1 with Existing System Infrastructure
Considerations (28.3%) (Structural Infrastructure Assessment); 2 with Operations & Maintenance
(21.7%) (Module cleaning methods, schedules, and water quality considerations). Exchanging
these topics changes the subject of one or more concerns rather than preserving their distinct
meanings.

Question 3
Which ordered set of topics best matches the following discussion points?
1. Electrical Theory and Measurement
2. Job Safety Analysis (JSA) and daily pre-task safety briefings

A. 1: Core Knowledge (30%); 2: Core Knowledge (30%)
B. 1: Safety (20%); 2: Safety (20%)
C. 1: Safety (20%); 2: Core Knowledge (30%)
D. 1: Core Knowledge (30%); 2: Safety (20%)

Correct Answer: D
Full Explanation: The correct associations are 1 with Core Knowledge (30%) (Electrical Theory
and Measurement); 2 with Safety (20%) (Job Safety Analysis (JSA) and daily pre-task safety
briefings). Exchanging these topics changes the subject of one or more concerns rather than
preserving their distinct meanings.



Question 4
Consider the following concerns in order. Which answer associates each one with its most
direct topic?
1. Systematic fault isolation workflows for low production or total system outages
2. Structural Infrastructure Assessment

A. 1: Operations & Maintenance (21.7%); 2: Operations & Maintenance (21.7%)
B. 1: Existing System Infrastructure Considerations (28.3%); 2: Existing System Infrastructure
Considerations (28.3%)
C. 1: Operations & Maintenance (21.7%); 2: Existing System Infrastructure Considerations
(28.3%)
D. 1: Existing System Infrastructure Considerations (28.3%); 2: Operations & Maintenance
(21.7%)

Correct Answer: C
Full Explanation: The correct associations are 1 with Operations & Maintenance (21.7%)
(Systematic fault isolation workflows for low production or total system outages); 2 with Existing
System Infrastructure Considerations (28.3%) (Structural Infrastructure Assessment). Exchanging
these topics changes the subject of one or more concerns rather than preserving their distinct
meanings.

Question 5
Which answer gives the correct topic for each numbered focus, without exchanging their roles?
1. Inspecting conduit runs, cable management, mechanical protection, and UV degradation
2. Energy Storage Systems (ESS) basic chemistries, configurations, and safety monitoring
systems
3. Reading and interpreting electrical single-line diagrams (SLDs), wiring schematics, and site
layouts
4. Series and parallel circuit configurations, voltage, current, and power relationships

A. 1: Core Knowledge (30%); 2: Existing System Infrastructure Considerations (28.3%); 3: Core
Knowledge (30%); 4: Core Knowledge (30%)
B. 1: Existing System Infrastructure Considerations (28.3%); 2: Core Knowledge (30%); 3: Core
Knowledge (30%); 4: Core Knowledge (30%)
C. 1: Core Knowledge (30%); 2: Core Knowledge (30%); 3: Existing System Infrastructure
Considerations (28.3%); 4: Core Knowledge (30%)
D. 1: Core Knowledge (30%); 2: Core Knowledge (30%); 3: Core Knowledge (30%); 4: Existing
System Infrastructure Considerations (28.3%)

Correct Answer: B
Full Explanation: The correct associations are 1 with Existing System Infrastructure
Considerations (28.3%) (Inspecting conduit runs, cable management, mechanical protection, and
UV degradation); 2 with Core Knowledge (30%) (Energy Storage Systems (ESS) basic chemistries,
configurations, and safety monitoring systems); 3 with Core Knowledge (30%) (Reading and
interpreting electrical single-line diagrams (SLDs), wiring schematics, and site layouts); 4 with
Core Knowledge (30%) (Series and parallel circuit configurations, voltage, current, and power
relationships). Exchanging these topics changes the subject of one or more concerns rather than
preserving their distinct meanings.



Question 6
Which subject would most directly address a task concerning Principles of solar generation and
semiconductor physics?

A. Core Knowledge (30%)
B. Safety (20%)
C. Existing System Infrastructure Considerations (28.3%)
D. Operations & Maintenance (21.7%)

Correct Answer: A
Full Explanation: Core Knowledge (30%) is the most direct match because its subject matter
includes Principles of solar generation and semiconductor physics. By contrast, Safety (20%)
concerns Personal Protective Equipment (PPE) Selection and Inspection. The relevant distinction is
the specific focus of the discussion, rather than a broad similarity between topics.
