-Set the command history buffer size.
-Recall previously entered commands.
Which tasks can be accomplished by using the command history feature? (Two answers)
Load a power-on self-test program.
What is the first action in the boot sequence when a switch is powered on?
Physical access to the router.
What must an administrator have in order to reset a lost password on a router?
username username secret secret
When configuring a switch for SSH access, what other command that is associated with the login local
command is required to be entered on the switch?
show controllers
Which command displays information about the auto-MDIX setting for a specific interface?
On the half-duplex end of the connection.
If one end of an Ethernet connection is configured for full duplex and the other end of the connection is
configured for half duplex, where would late collisions be observed?
boot system
Which command is used to set the BOOT environment variable that defines where to find the IOS image
file on a switch?
BOOT environment variable
What does a switch use to locate and load the IOS image?
SSH
, Which protocol adds security to remote connections?
It is a logical interface internal to the router.
What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?
64 bytes
What is the minimum Ethernet frame size that will not be discarded by the receiver as a runt frame?
After POST execution
After which step of the switch bootup sequence is the boot loader executed?
An increase in the size of the broadcast domain.
Which impact does adding a Layer 2 switch have on a network?
Frames are forwarded without any error checking.
Which characteristic describes cut-through switching?
A hub extends a collision domain, and a switch divides collision domains.
What is the significant difference between a hub and a Layer 2 LAN switch?
They store frames received, thus preventing premature frame discarding when network congestion
occurs.
How do switch buffers affect network performance?
True
In an Ethernet switch, Frame forwarding decisions are based on MAC address and port mappings in the
CAM table. True or false?
High port density
Which switch characteristic helps keep traffic local and alleviates network congestion?
ASIC (Application-Specific Integrated Circuits)
Which switch component reduces the amount of packet handling time inside the switch?
Refer to the exhibit. A switch receives a Layer 2 frame that contains a source MAC address of
000b.a023.c501 and a destination MAC address of 0050.0fae.75aa. Place the switch steps in the order
they occur. (Not all options are used.)
