Networking Devices and Initial
Configuration 4-6 Test. Latest 2026-
2027. Questions & Correct Answers.
Graded A
For what purpose are IPv4 addresses utilized? - AnsAn IPv4 address is
used to uniquely identify a device on an IP network.
A MAC address is burned into a NIC to uniquely identify a device. A port
number is used to uniquely identify the application that requested
information. The subnet mask identifies how many hosts can be on a
network and the network number. There is not really any parameter that
identifies the number of free IP networks.
How does the network layer use the MTU value? - AnsThe data link layer
indicates to the network layer the MTU for the medium that is being used.
The network layer uses that information to determine how large the packet
can be when it is forwarded. When packets are received on one medium
and forwarded on a medium with a smaller MTU, the network layer device
can fragment the packet to accommodate the smaller size.
How many octets exist in an IPv4 address? - Ans4
1
, Each octet holds 8 bits and an IPv4 address contains 32 bits. Therefore, an
IPv4 address contains four octets.
How many unique addresses are available for assignment to hosts in the
network of 10.100.16.0 with subnet mask 255.255.252.0? - Ans1022
Match the components in the notation 100Base-T to the specification. -
AnsBASE- Baseband transmission
T- Twisted-pair cable
100- Speed in Mbps
What addressing information is recorded by a switch to build its MAC
address table? - Ansthe source Layer 2 address of incoming frames
What do devices on the same IPv4 subnet have in common? - AnsThey all
use the same default gateway.
What happens to runt frames received by a Cisco Ethernet switch? -
AnsThe frame is dropped.
What important information is examined in the Ethernet frame header by a
Layer 2 device in order to forward the data onward? - Ansdestination MAC
address
