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?
a. on both ends of the connection
b. on the full-duplex end of the connection
c. only on serial interfaces
d. on the half-duplex end of the connection
what is
d. on the half-duplex end of the connection
Full-duplex communications do not produce collisions. However, collisions often occur in half-duplex operations. When a connection has two different duplex configurations, the half-duplex end will experience late collisions. Collisions are found on Ethernet networks. Serial interfaces use technologies other than Ethernet.

What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?
a. It is a logical interface internal to the router.
b. Only one loopback interface can be enabled on a router.
what is
a. It is a logical interface internal to the router.
The loopback interface is a logical interface internal to the router and is automatically placed in an UP state, as long as the router is functioning. It is not assigned to a physical port and can therefore never be connected to any other device. Multiple loopback interfaces can be enabled on a router.

1.1.4 Basic Router Configuration
Which command is used to set the BOOT environment variable that defines where to find the IOS image file on a switch?
a. config-register
b. boot system
c. boot loader
what is
b. boot system
The boot system command is used to set the BOOT environment variable. The config-register and confreg commands are used to set the configuration register. The boot loader command supports commands to format the flash file system, reinstall the operating system software, and recover from a lost or forgotten password.

What is the minimum Ethernet frame size that will not be discarded by the receiver as a runt frame?
a. 64 bytes
b. 512 bytes
c. 1024 bytes
what is
a. 64 bytes
The minimum Ethernet frame size is 64 bytes. Frames smaller than 64 bytes are considered collision fragments or runt frames and are discarded.

After which step of the switch bootup sequence is the boot loader executed?
a. after CPU initialization
b. after IOS localization
c. after flash file system initialization
what is
c. after flash file system initialization
The correct bootup sequence order is as follows:
1.- The switch loads and executes the POST.
2.- The switch loads the boot loader software.
3.- The boot loader performs low-level CPU initialization.
4.- The boot loader initializes the flash memory.
5.- The boot loader locates and loads the default IOS image.
