Answer: Protocols developed by organizations who have control over
their definition and operation
●● What service is provided by DNS?
Answer: Resolves domain names, such as cisco.com, into IP addresses.
●● A client packet is received by a server. The packet has a destination
port number of 110. What service is the client requesting?
,Answer: POP3
●● What command can be used on a Windows PC to see the IP
configuration of that computer?

●● A wired laser printer is attached to a home computer. That printer has
been shared so that other computers on the home network can also use
the printer. What networking model is in use?
Answer: peer-to-peer (P2P)
●● What characteristic describes a virus?
Answer: malicious software or code running on an end device
●● 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

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.

table that is shown?
, Answer: ARP
●● A network administrator notices that some newly installed Ethernet
cabling is carrying 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?
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?A host is trying to send a
packet to a device on a remote LAN segment, but there are currently no
mappings in the 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.
