Under which two circumstances should Spanning Tree Protocol be implemented? (Choose two.)
A.
to ensure a loop-free topology
B.
to protect against user-side loops
C.
when a VLAN spans access layer switches
D.
for the most deterministic and highly available network topology
E.
because of the risk of lost connectivity without Spanning Tree Protocol CareerCert.blogspot.com
I see another badly written question. If you know your STP you know that STP is to ensure a loop-free topology and B and C and D and finally E.
I’m sure I’ll find what Mr Tiso says in his ARCH book but it’s not what you’d call a great book.
I hope this question has been removed from the exam.
