Which issue could cause the Blocked status on A2?
A1 and A2 being connected to different switches could cause the Blocked status on A2. Link Aggregation Control Protocol (LACP) assumes that all member links in an aggregation group are connected to the same partner switch. If A1 and A2 are connected to different switches, the LACP mechanism is likely to block one of the links to prevent misconfiguration or a loop, resulting in the Blocked status for port A2.
A is right.
A is only logical answer.
A is the correct answer because an aggregation link its one logical port for STP protocol.
