Which statement regarding redundant trunk groups (RTGs) is true?

A.
STP and RTG can be configured on the same interface.

B.
An aggregated interface can be a member of an RTG.

C.
Members of an RTG can carry different VLANs.

D.
An RTG can contain up to 16 member links.

Explanation:
Enable RTG on the LAG Uplinks

A Redundant Trunk Group is an L2 link failover mechanism supported on the EX4200/EX4500 switches. It is ideally implemented on an access switch or Virtual Chassis with a dual home connection, where one link is active and forwards traffic while the other blocks traffic and acts as a backup to the active link. This feature eliminates configuring Spanning Tree Protocol (STP) on the switch if RTG previously has been enabled.
