What are three advantages of a collapsed-core architecture? (Choose three.)

A.
This design provides the most efficient use of ports because no ports are consumed for ISLs.

B.
The absence of ISLs significantly decreases reliability and manageability.

C.
The absence of any oversubscription increases switch throughput.

D.
Since there are fewer available paths over which traffic may travel, FSPF values are higher.

E.
Ports can be scaled easily by adding hot-swappable blades without disrupting traffic.

F.
The highest performance is achieved by director-class switches, because the high-speed backplane provides low fixed latency between any two ports.
