The Libero designation rule states that a team can designate zero or one Libero for each set, or two Liberos for the match.

• A. True
• B. False
• C. Only in the final set
• D. Only if both Libero players are on the court at the same time

Answer: (A)

The rule being tested is about how teams designate a Libero and how that designation can work across sets. The Libero is a defensive specialist who can replace back-row players, and teams have flexibility in how they designate Liberos from set to set or for the whole match.

The statement is correct because you may choose to designate a Libero for each set individually, meaning you can have zero or one Libero on a per-set basis. Alternatively, you can designate two Liberos for the entire match. If two Liberos are designated for the match, only one can be on the court at any given time, serving as the back-row replacement option across sets. This design keeps the libero role focused on defense while allowing teams to plan for backup coverage across sets.

In practice, Liberos must stay in the back row and cannot attack from in front of the attack line or make front-row plays in ways that violate the libero rules. They wear a distinct jersey and are used specifically to strengthen back-row defense, not to change the front-row dynamics.

The other options don’t fit because this rule isn’t limited to the final set, and it doesn’t require both Liberos to be on the court simultaneously; the designations refer to who is allowed to be used, not to having two on the court at the same time.
