It exits configuration mode and returns to user EXEC mode.
It moves the cursor to the beginning of the next line.
It completes the remainder of a partially typed word in a command.
What layer is responsible for routing messages through an internetwork in the TCP/IP model?
internet
transport
network access
session
Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?
Data is sent from the internet layer to the network access layer.
Packets are sent from the network access layer to the transport layer.
Segments are sent from the transport layer to the internet layer.
Frames are sent from the network access layer to the internet layer.
What unique address is embedded in an Ethernet NIC and used for communication on an Ethernet network?
host address
IP address
MAC address
network address
k layer
Which procedure is used to reduce the effect of crosstalk in copper cables?
requiring proper grounding connections
twisting opposing circuit wire pairs together
wrapping the bundle of wires with metallic shielding
designing a cable infrastructure to avoid crosstalk interference
avoiding sharp bends during installation
During the encapsulation process, what occurs at the data link layer for a PC connected to an Ethernet network?
An IP address is added.
The logical address is added
The physical address is added.
The process port number is added.
What are two characteristics of Ethernet MAC addresses? (Choose two.)
They are globally unique.
They are routable on the Internet.
They are expressed as 12 hexadecimal digits.
MAC addresses use a flexible hierarchical structure.
MAC addresses must be unique for both Ethernet and serial interfaces on a device.
If a device receives an Ethernet frame of 60 bytes, what will it do?
drop the frame
process the frame as it is
send an error message to the sending device
add random data bytes to make it 64 bytes long and then forward it
Under which two circumstances will a switch flood a frame out of every port except the port that the frame was received on? (Choose two.)
The frame has the broadcast address as the destination address.
The destination address is unknown to the switch.
The source address in the frame header is the broadcast address.
The source address in the frame is a multicast address.
The destination address in the frame is a known unicast address.
Which switching method has the lowest level of latency?
cut-through
store-and-forward
fragment-fre
fast-forward
Which two commands can be used on a Windows host to display the routing table? (Choose two.)
netstat -s
route print
show ip route
netstat -r
tracert
Which two functions are primary functions of a router? (Choose two.)
packet forwarding
microsegmentation
domain name resolution
path selection
flow control
What is the binary representation of 0xCA?
10111010
11010101
11001010
11011010
At a minimum, which address is required on IPv6-enabled interfaces?
link-local
unique local
site local
global unicast
Which service provides dynamic global IPv6 addressing to end devices without using a server that keeps a record of available IPv6 addresses?
stateful DHCPv6
SLAAC
static IPv6 addressing
stateless DHCPv6
What is the purpose of the command ping ::1?
It tests the internal configuration of an IPv6 host.
It tests the broadcast capability of all hosts on the subnet.
It tests the multicast connectivity to all hosts on the subnet.
It tests the reachability of the default gateway for the network.
How many usable IP addresses are available on the 192.168.1.0/27 network?
32
254
62
30
16
What is the process of dividing a data stream into smaller pieces before transmission?
segmentation
encapsulation
encoding
flow control
When IPv4 addressing is manually configured on a web server, which property of the IPv4 configuration identifies the network and host portion for an IPv4 address?
DNS server address
subnet mask
default gateway
DHCP server address
Which two roles can a computer assume in a peer-to-peer network where a file is being shared between two computers? (Choose two.)
client
master
server
slave
transient
Which two protocols operate at the highest layer of the TCP/IP protocol stack? (Choose two.)
DNS
Ethernet
IP
POP
UDP
What is one difference between the client-server and peer-to-peer network models?
Only in the client-server model can file transfers occur.
Every device in a peer-to-peer network can function as a client or a server.
A peer-to-peer network transfers data faster than a transfer using a client-server network.
A data transfer that uses a device serving in a client role requires that a dedicated server be present.
What is the function of the HTTP GET message?
to request an HTML page from a web server
to send error information from a web server to a web client
to upload content to a web server from a web client
to retrieve client email from an email server using TCP port 110
Which networking model is being used when an author uploads one chapter document to a file server of a book publisher?
peer-to-peer
master-slave
client/server
point-to-point
What network service resolves the URL entered on a PC to the IP address of the destination server?
DNS
DHCP
FTP
SNMP
