Click the exhibit button below. A network operator has configured a network-queue policy to map forwarding classes to queues, as shown in the exhibit below. Based on the default scheduling behavior of the Nokia 7750 SR, in which order will packets be serviced?

All in-profile packets in round-robin, then all out-of-profile packets in biased round-robin.
In-profile EF packets, then in-profile H2 packets, then in-profile AF packets, then out-of-profile EF packets, then out-of-profile H2 and AF packets, and then out-of-profile BE packets.
In-profile EF, H2 and AF packets, then out-of-profile H2, AF and BE packets in biased round-robin.
In-profile EF packets, then in-profile H2 and AF packets, then out-of-profile H2, AF and BE packets in biased round-robin.
In-profile EF and H2 packets, then in-profile AF packets, then out-of-profile H2, AF and BE packets in biased round-robin.
