A.
BPDUfilter
B.
PortFast
C.
Backbonefast
D.

PortFast
Explanation: PortFast
Spanning Tree Portfast causes layer 2 switch interfaces to enter forwarding state
immediately, bypassing the listening and learning states. It should be used on ports connected directly to end hosts like servers or workstations. Note: If portfast isn’t enabled,
DHCP timeouts can occur while STP converges, causing more problems.

The operations team resides on the 10.20.1.0/25 network. Which command will accomplish
this task?
A.
access-list 2699 permit udp 10.20.1.0 0.0.0.255
B.
no access-list 2699 deny tcp any 10.20.1.0 0.0.0.127 eq 22
C.
access-list 2699 permit tcp any 10.20.1.0 0.0.0.255 eq 22
D.
no access-list 2699 deny ip any 10.20.1.0 0.0.0.255
no access-list 2699 deny ip any 10.20.1.0 0.0.0.255
Explanation: Note : Already a statement is there in last to allow SSH Traffic for network
10.20.1.0 0.0.0.127, but Second statement says deny ip any 10.20.1.0 0.0.0.255, so how it
will work once it is denied. So the right answer is remove the -- no access-list 2699 deny ip
any 10.20.1.0 0.0.0.255.
