Sample NV C-4F Sheet Metal Studs Practice Questions

Try these sample questions to test your NV C-4F Sheet Metal Studs exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under NAC 624.220, what work does a Nevada C-4F Sheet Metal Studs license authorize?
A.Erection and installation of sheet-metal studs for ceiling framing and nonstructural partitioning
B.Installation of wood studs and structural steel beams
C.Welding of structural wide-flange columns
D.Taping and finishing of gypsum wallboard only
Explanation: NAC 624.220(2)(f) defines C-4F as the erection and installation of sheet-metal studs for framing ceilings and for nonstructural partitioning. The same sentence excludes wood and structural steel framing. Taping and finishing is C-4C; gypsum board hanging is C-4E.
2Which framing material is expressly outside the Nevada C-4F subclassification?
A.25-gauge drywall studs
B.Cold-formed steel ceiling furring channels
C.Wood studs or structural steel used for framing
D.Nonstructural 3-5/8-inch steel studs
Explanation: NAC 624.220(2)(f) authorizes sheet-metal studs for ceilings and nonstructural partitions, “but not the installation of wood or structural steel for framing.” Ordinary 25-gauge studs and furring channels used as nonstructural ceiling framing stay inside C-4F.
3Under IBC 2018 Section 2211.2, the design and installation of cold-formed steel nonstructural members shall comply with which standard?
A.AISI S240
B.AISC 360
C.AISI S100 only, with no framing standard
D.AISI S220
Explanation: IBC 2018 2211.2 sends nonstructural cold-formed steel light-frame members and connections to AISI S220. AISI S240 is the companion structural-framing standard in 2211.1. AISC 360 is hot-rolled structural steel, not interior drywall studs.
4IBC 2018 Section 2211.1 requires which standard for cold-formed steel structural light-frame systems such as load-bearing walls?
A.AISI S220
B.ASTM C645 only
C.AISI S240
D.GA-216
Explanation: IBC 2018 2211.1 assigns floor, roof, and structural-wall cold-formed steel systems to AISI S240. C-4F work stays on the nonstructural side of that split (S220). ASTM C645 is a product specification historically used for nonstructural members; GA-216 is gypsum application.
5IBC 2018 Section 1607.15 requires interior walls and partitions taller than 6 feet, including finishes, to resist a horizontal load of not less than which value?
A.5 psf
B.15 psf
C.20 psf
D.40 psf
Explanation: IBC 2018 1607.15 sets a minimum 5 psf horizontal load on interior walls and partitions that exceed 6 feet in height. That 5 psf value is also the load used with Table 1604.3 deflection limits and with ASTM C754 limiting-height tables. Do not confuse it with the 15 psf floor live-load allowance for movable partitions in 1607.5.
6Per IBC 2018 Table 1604.3, what is the deflection limit for an interior partition with other brittle finishes (not plaster or stucco)?
A.L/120
B.L/180
C.L/240
D.L/480
Explanation: Table 1604.3 lists interior partitions with other brittle finishes at L/240 under the live-load (horizontal) column. Gypsum board is commonly treated as this brittle-finish case, which is why ASTM C754 L/240 columns are the usual interior-partition check. The table footnote ties the limit to the 1607.15 horizontal load.
7Per IBC 2018 Table 1604.3, an interior partition finished with plaster or stucco is limited to which deflection?
A.L/120
B.L/240
C.L/360
D.L/600
Explanation: Table 1604.3 gives interior partitions with plaster or stucco finishes an L/360 limit. Plaster cracks if the studs flex too much, so the code is stricter than the L/240 brittle or L/120 flexible rows. Select a deeper, thicker, or closer-spaced stud from the ASTM C754 L/360 column.
8IBC 2018 Table 1604.3 allows which deflection for an interior partition that has a flexible finish?
A.L/120
B.L/240
C.L/360
D.No deflection limit applies
Explanation: The flexible-finish row for interior partitions is L/120. That is the most generous of the three partition rows and is the other end of the ASTM C754 L/120–L/240–L/360 set. Flexible, folding, and portable partitions are exempt by table footnote; a built-in metal-stud wall is not.
9IBC 2018 Section 718.2.2 requires fireblocking in concealed stud-wall spaces horizontally at intervals not exceeding what distance?
A.4 feet
B.8 feet
C.10 feet
D.25 feet
Explanation: IBC 2018 718.2.2 requires fireblocking in concealed spaces of stud walls and partitions, including furred spaces and parallel or staggered stud rows, horizontally at intervals not exceeding 10 feet. The same section also requires fireblocking vertically at floor and ceiling levels. Double-stud and chase walls are the usual C-4F places this appears.
10Besides the 10-foot horizontal interval, where else does IBC 2018 Section 718.2.2 require fireblocking in concealed stud-wall spaces?
A.Vertically at the ceiling and floor levels
B.Only at mid-height of every stud
C.Only where electrical boxes occur
D.Only in load-bearing walls
Explanation: Section 718.2.2 item 1 requires fireblocking vertically at the ceiling and floor levels; item 2 is the 10-foot horizontal interval. The rule applies to stud walls and partitions, including nonstructural metal-stud and furred spaces, not only load-bearing walls. Mid-height bridging is a stiffness detail, not a substitute for code fireblocking.
