Explanation

A snapshot standby cannot be the target of a switchover or fast-start failover operation. You can, however, perform a manual failover to a snapshot standby. A far sync instance is not a database and therefore cannot be the target of a role transition. For fast-start failover, you must pre-select the target standby database that will be used. If the Oracle Data Guard configuration is operating in maximum protection mode, the broker does not allow a switchover to occur to a logical standby database. The configuration must be operating in either maximum availability mode or maximum performance mode in order to be able to switch over to a logical standby database.
