Exhibit:
You have an ESXi host that is connected to ge-0/0/23 on a Juniper EX Series switch. You added a new VM that will also use the same ge-0/0/23 interface. Unfortunately, the new VM is not able to reach external devices.
Referring to the exhibit, which command would solve this problem?
A. set vlans default switch-options interface-mac-limit 4
B. set vlans default switch-options interface-mac-limit 5
C. set switch-options interface ge-0/0/23.0 interface-mac-limit 3
D. clear ethernet-switching recovery-timeout interface ge-0/0/23.0

B. RSTP alternate ports provide an alternate lower cost path to the root bridge.
C. RSTP alternate ports provide an alternate higher cost path to the root bridge.
D. RSTP alternate ports are active ports used to forward frames toward the root bridge.

A. EBGP routers will append their AS number when advertising routes to their neighbors.
B. EBGP routers will only accept routes that contain their own AS number in the AS_PATH.
C. EBGP routers will drop routes that contain their own AS number in the AS_PATH
D. EBGP routers will prepend their AS number when advertising routes to their neighbors
