Type B2 Extra Duty Site is best described as which of the following?

• A. Sites normally occupied and have co-located tower
• B. Sites not normally occupied and no tower
• C. No lightning exposure
• D. Uses only copper ground rods

Answer: (A)

This item tests how Type B2 Extra Duty Site is defined in R56, focusing on occupancy and tower presence. Extra Duty implies a site that's actively used and staffed, rather than a passive or unmanned location, and having a co-located tower means multiple antennas or systems share the same tower footprint. Together, these factors describe a site that is normally occupied and has a co-located tower, which is why that option best fits the definition.

The other descriptions don’t match this classification: a site not normally occupied and without a tower is typically a simpler, less active site; claiming no lightning exposure isn’t realistic since outdoor equipment at these sites is exposed to weather and requires protection; and grounding details like using only copper ground rods aren’t what define the site type.
