Three bank employees are using the corporate network. The first employee uses a web
browser to view a company web page in order to read some announcements. The
second employee accesses the corporate database to perform some financial
transactions. The third employee participates in an important live audio conference with
other corporate managers in branch offices. If QoS is implemented on this network,
what will be the priorities from highest to lowest of the different data types? - Answer -
audio conference, financial transactions, web page
This is the portion of the address assigned by the provider - Answer -global routing
prefix
,This part of the address is used by an organization to identify subnets. - Answer -
subnet ID
This part of the address is the equivalent to the host portion of an IPv4 address. -
Answer -interface ID (IPv6)
Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the
TCP/IP model would be used? - Answer -application, transport, Internet, and network
access layers
cut-through switching - Answer -low latency
may forward runt frames
begins forwarding when destination address is recived
store-and-forward switching - Answer -always stores entire frame
checks the CRC before forwarding
checks the frame length before forwarding
Refer to the exhibit. The IP address of which device interface should be used as the
default gateway setting of host H1? - Answer -R1: G0/0
What service is provided by Internet Messenger? - Answer -An application that allows
real-time chatting among remote users.
Match the network with the correct IP address and prefix that will satisfy the usable host
addressing requirements for each network. - Answer -Explanation: Network A needs to
use 192.168.0.128 /25, which yields 128 host addresses.Network B needs to use
192.168.0.0 /26, which yields 64 host addresses.Network C needs to use 192.168.0.96
/27, which yields 32 host addresses.Network D needs to use 192.168.0.80/30, which
yields 4 host addresses.
Refer to the exhibit. Which protocol was responsible for building the table that is shown?
- Answer -ARP
Explanation: The table that is shown corresponds to the output of the arp -a command,
a command that is used on a Windows PC to display the ARP table.

corrupt and distorted data signals. The new cabling was installed in the ceiling close to
fluorescent lights and electrical equipment. Which two factors may interfere with the
copper cabling and result in signal distortion and data corruption? (Choose two.) -
Answer -RFI
EMI
, A host is trying to send a packet to a device on a remote LAN segment, but there are
currently no mappings in its ARP cache. How will the device obtain a destination MAC
address? - Answer -It will send an ARP request for the MAC address of the default
gateway.
A client packet is received by a server. The packet has a destination port number of 53.
What service is the client requesting? - Answer -DNS
A network administrator is adding a new LAN to a branch office. The new LAN must
support 25 connected devices. What is the smallest network mask that the network
administrator can use for the new network? - Answer -255.255.255.224
What characteristic describes a Trojan horse? - Answer -malicious software or code
running on an end device
What service is provided by HTTPS? - Answer -Uses encryption to secure the
exchange of text, graphic images, sound, and video on the web.
A technician with a PC is using multiple applications while connected to the Internet.
How is the PC able to keep track of the data flow between multiple application sessions
and have each application receive the correct packet flows? - Answer -The data flow is
being tracked based on the source port number that is used by each application.
Explanation: The source port number of an application is randomly generated and used
to individually keep track of each session connecting out to the Internet. Each
application will use a unique source port number to provide simultaneous
communication from multiple applications through the Internet.
A network administrator is adding a new LAN to a branch office. The new LAN must
support 61 connected devices. What is the smallest network mask that the network
administrator can use for the new network? - Answer -255.255.255.192
Refer to the exhibit. Match the network with the correct IP address and prefix that will
satisfy the usable host addressing requirements for each network. (Not all options are
used.) - Answer -Explanation:Network A needs to use 192.168.0.0 /25 which yields 128
host addresses.Network B needs to use 192.168.0.128 /26 which yields 64 host
addresses.Network C needs to use 192.168.0.192 /27 which yields 32 host
addresses.Network D needs to use 192.168.0.224 /30 which yields 4 host addresses.
What characteristic describes a DoS attack? - Answer -an attack that slows or crashes
a device or network service
