How many A2 type switch jacks are found on the panel?

• A. 0
• B. 2
• C. 1
• D. 4

Answer: (C)

The key idea is identifying how many A2 switch jacks are actually present on the panel. An A2 switch jack is a specific type of connector on the panel that includes a switching action when a plug is inserted. In this setup, there is only one jack that is designated as or designed like an A2 switch jack, and no additional A2 jacks are shown on the panel. So, when you count the A2-type jacks by looking at the panel diagram or labeling, you arrive at a single instance. If the diagram or labeling showed more, you’d see multiple A2 jacks, but here only one is present.
