Your network has Junos Fusion configured with MX960 routers as aggregation devices (AD) and QFX5100 switches as satellite devices (SD). Which two statements are correct in this scenario? (Choose two.)
A.
All SDs connected to a single AD must use the same software version.
B.
SDs are added to the AD by configuring the cascade port on the AD.
C.
The Fusion extended ports are configured on the SDs.
D.
The AD runs the Junos software for all its connected SDs.
BD.
A is wrong: Different satellite devices can run different versions of satellite software within the same Junos Fusion. (https://www.juniper.net/documentation/en_US/junos/topics/concept/fusion-software.html)
C is wrong: All Junos Fusion management responsibilities, including interface configuration for every satellite device interface in the Junos Fusion, are handled by the aggregation device.
AD - An EX9200 switch acting as an aggregation device in a Junos Fusion Enterprise is responsible for almost all management tasks, including interface configuration for every satellite device interface in the topology. The aggregation device runs Junos OS software for the entire Junos Fusion Enterprise, and the network-facing interfaces on the satellite devices—called extended ports—are configured from the aggregation device and support features that are supported by the version of Junos OS running on the aggregation device.
CD
You need to do more on AD and SD to attach a SD. Not just configuring the AD cascade port
