How are ports scaled on vSphere Standard Switches (vSS)?
A. Ports on a vSS can be dynamically scaled up and down.
B. Ports on a vSS can only be statically scaled up or down.
C. Ports on a vSS can only be dynamically scaled down.
D. Ports on a vSS can only be dynamically scaled up.
correct answer
Number of Standard Ports
To ensure efficient use of host resources on hosts running ESXi 5.5 and later, the number of ports of standard switches are dynamically scaled up and down. A standard switch on such a host can expand up to the maximum number of ports supported on the host.
but the Ports on a VSS can manuell scaled up or down !!!
