What are 4 ways network management can be simplified by using the virtual LANs (VLANs)?
A -
It is no longer necessary to install cables to move a user from a new network to another.
B -
A group of users needing high security can be put into a VLAN so that no users outside the VLANs can communicate with them.
C -
Network adds, moves and changes are achieved by configuring a port into a VLAN.
D -
All of the above.
2-
With one method of transmitting fames through a switch the switch receives the complete frame and
checks the frame CRC before forwarding the frame. What is this transmitting method called?
A -
Stored and forwarded.
B -
Fragmentation.
C -
Half duplex.
D -
Cut through.
3-
Switching methods include cut-through, store and forwarded and a modified version of the first two
methods. Which statement about switching methods is true?
A -
The stored and forward method has low latency.
B -
The cut through method and switching has high latency.
C -
The modified version holds the packet in memory until 50% of the packet reaches the switch.
D -
The modified version holds the packet in memory until the data portion of the packet reaches the switch.
4-
Which technology do catalyst switches use to resolve topology loops and ensure data use flows properly
through a single network path?
A -
Cut through switching.
B -
Spanning tree protocol.
C -
Frame filtering.
D -
Virtual LANs.
5-
Which two statements are true? (Choose two)
A -
Ethernet 802.3 utilizes a half duplex method for data transfer.
B -
Full duplex Ethernet takes advantage of UTP using one pair of transmission and other pair for reception.
C -
Ethernet switches can use the full duplex mode to connect multiple nodes on a single port office switch.
D -
Both A & B
6-
What is a backoff on an 802.3 network?
A -
It is latency in store and forward switching.
B -
It is the time used for token passing for machine to machine.
C -
It is the retransmission delay that is reinforced when a collision occurs.
D -
It is the result of two nodes transmitting at a same time the frames from each transmitting device collide and are damaged.
7-
You have just issued an erase startup-config command and reloaded your router. In which mode will
your router be when you reboot?
A -
Setup.
B -
Startup.
C -
User EXEC.
D -
User privileged.
8-
What is a key use of a device hardware address?
A -
To obtain a vendor code/serial number from the user.
B -
To transmit a frame from one interface to another interface.
C -
To transmit a packet from one local device to another local device.
D -
To transmit data from one local device to remote device across Internet.
9-
Which command verifies encapsulation as well as layer 1 and layer 2 statistics on a router configured for
Frame Relay?
A -
Show IP
B -
Show interface
C -
Show statistics
D -
Show frame-relay
10-
Which element is used to define the rate, in bits per second, which a Frame Relay switch agrees to
transfer data?
