Ccna certification Practice Tests

A.  There are no problems with the interface.

B.  The interface is auto-negotiating speed and duplex.

C.  There are a large number of broadcasts.

D.  The node needs a faster network interface.

 87.  You have statically set an interface to 100 Mb/s full-duplex. However, the device you are 

plugging in will not work. Which command would you use to set speed and duplex back 

to auto-negotiate?

A. 

Switch(config-if)#speed auto

 

Switch(config-if)#duplex auto

B. 

Switch(config-if)#speed autonegotiate

 

Switch(config-if)#duplex autonegotiate

C. 

Switch(config-if)#switchport autonegotiate

D. 

Switch(config-if)#interface autonegotiate

 88.  You have auto-negotiation turned off on the node, but it is turned on at the switch’s 

interface connecting the node. The interface is a 10/100/1000 Mb/s interface and the node 

is 100 Mb/s full-duplex. What will the outcome be when you plug in the node?

A.  The switch interface will be set to the 100 Mb/s full-duplex.

B.  The switch interface will be set to the 100 Mb/s half-duplex.

C.  The switch interface will be set to the 10 Mb/s full-duplex.

D.  The switch interface will be set to the 10 Mb/s half-duplex.

 89.  You plug a 100 Mb/s hub into a switch. What is the expected outcome?

A.  The switch interface will be set to the 100 Mb/s full-duplex.

B.  The switch interface will be set to the 100 Mb/s half-duplex.

C.  The switch interface will be set to the 10 Mb/s full-duplex.

D.  The switch interface will be set to the 10 Mb/s half-duplex.

 90.  You want to see the status of all speed and duplex negotiations for all interfaces. Which 

command would you use?
