PART II: THE ELITE TEST BANK
Tier 1 (Questions 1–18) - Foundational Syntax & Application
Q1: Under the strict mandates of AS 1428.1:2021 regarding accessible lever handles, what is
the EXACT required grip clearance between the inner face of the handle and the door surface?
A) 25–35 mm B) 30–40 mm C) 35–45 mm D) 40–50 mm
● Answer: C (35–45 mm)
● Distractor Analysis:
○ A is incorrect: This clearance is too shallow, preventing a full hand from passing
behind the lever without pinching.
○ B is incorrect: While close, this relies on outdated accessibility assumptions rather
than the current codified standard.
○ D is incorrect: This exceeds the mandated standard and may cause the lever to
protrude hazardously into the egress path.
The Mentor's Analysis: AS 1428.1 explicitly mandates a 35–45 mm clearance to allow users
with restricted hand mobility to safely operate the hardware. By strictly adhering to this metric,
practitioners ensure the door remains universally accessible without requiring tight grasping.
Professional Intuition: Compliance is measured in millimeters; never estimate clearances on
accessible hardware.
Q2: When auditing a fire doorset for compliance with AS 1905.1, a technician measures the gap
between the door leaf and the frame. What is the MAXIMUM allowable clearance before an AS
1530.4 compliant upgrade is required? A) 2 mm B) 3 mm C) 4 mm D) 5 mm
● Answer: B (3 mm)
● Distractor Analysis:
○ A is incorrect: While a 2 mm gap is compliant, it is not the maximum allowable
threshold.
○ C is incorrect: A 4 mm gap violates AS 1905.1 and requires a retrofitted
, intumescent seal to restore compliance.
○ D is incorrect: A 5 mm gap represents a severe fire compartmentation failure and
immediate life safety risk.
The Mentor's Analysis: Fire doors rely on tight tolerances to prevent smoke and flame
propagation. Once the gap exceeds 3 mm, the door fails AS 1905.1 compliance and requires
immediate remediation with tested intumescent seals. Professional Intuition: A fire door with a
4 mm gap is no longer a fire door; it is a liability.
Q3: According to the Security Industry Association (SIA), which cryptographic standard is
utilized by the Open Supervised Device Protocol (OSDP v2.2) Secure Channel Protocol (SCP)?
A) DES-56 B) AES-128 C) RSA-1024 D) SHA-256
● Answer: B (AES-128)
● Distractor Analysis:
○ A is incorrect: DES is a deprecated legacy encryption standard highly vulnerable to
brute-force attacks.
○ C is incorrect: RSA is an asymmetric algorithm typically used for key exchange, not
the symmetric encryption used in OSDP SCP payloads.
○ D is incorrect: SHA-256 is a hashing algorithm for data integrity, not the primary
payload encryption cipher.
The Mentor's Analysis: OSDP v2.2 neutralizes the cleartext vulnerabilities of legacy Wiegand
systems by deploying AES-128 encryption across the RS-485 bus. This secures the credential
data payload against sniffing and cloning attacks at the edge. Professional Intuition: Without
SCP enabled, OSDP is merely supervised Wiegand; encryption is the true shield.
Q4: In an SFIC A2 master key system, the sum of the bottom, master, control, and top pins in a
single chamber must ALWAYS equal what total stack height? A) 19 B) 21 C) 23 D) 25
● Answer: C (23)
● Distractor Analysis:
○ A is incorrect: This applies to older or proprietary systems, not the standardized A2
mathematical matrix.
○ B is incorrect: A stack of 21 will fail to reach the spring cover, causing catastrophic
cylinder binding.
○ D is incorrect: A stack of 25 over-packs the chamber, destroying the spring and
preventing plug rotation.
The Mentor's Analysis: The SFIC A2 system is mathematically absolute. The total pin stack
must equal exactly 23 to ensure spring tension is uniform and both the operating and control
shear lines function flawlessly. Professional Intuition: If the math does not equal 23, the
cylinder will fail; the A2 system tolerates zero deviation.
Q5: Under the Northern Territory Private Security Act 1995, providing locksmithing services on
commercial access control systems requires which PRIMARY qualification pathway? A) AQF
Certificate II in Security Operations B) AQF Certificate III in Locksmithing (or equivalent) C)
Restricted Electrical Licence (REL) D) Master Locksmiths Association Membership
● Answer: B (AQF Certificate III in Locksmithing (or equivalent))
● Distractor Analysis:
○ A is incorrect: Certificate II covers basic security operations (guarding), not the
mechanical or electronic complexities of locksmithing.
○ C is incorrect: While an REL is useful for high-voltage relays, it is not the statutory
requirement for the locksmith licence class.
○ D is incorrect: MLAA membership is an industry credential, not the statutory legal
requirement for a government-issued licence.
