switches is having a duplex mismatch. Which command would the technician use to see
the Layer 1 and Layer 2 details of a switch port? - ANS-Show interfaces
Where are Cisco IOS debug output messages sent by default? - ANS-Console Line
Which command can an administrator issue on a Cisco router to send debug messages
to the vty lines? - ANS-Terminal Monitor
What is one indication that a Windows computer did not receive an IPv4 address from a
DHCP server? - ANS-The computer receives an IP address that starts with 169.254
What source IP address does a router use by default when the traceroute command is
issued? - ANS-The IP address of the outbound interface.
A user is unable to reach the web site when typing http://www.cisco.com in a web
browser, but can reach the same site by typing http://72.163.4.161. What is the issue? -
ANS-DNS
What is a characteristic of a fault tolerant network? - ANS-A network that recovers
quickly when a failure occurs and depends on redundancy to limit the impact of a
failure.
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? - ANS-Audio
conference, Financial transactions, and Web page.
What is a benefit of using cloud computing in networking? - ANS-Network capabilities
are extended without requiring investment in new infrastructure, personnel, or software.
What is the function of the shell in an OS? - ANS-It interfaces between the users and
the kernel.
, Which connection provides a secure CLI session with encryption to a Cisco switch? -
ANS-An SSH connection.
A network technician is attempting to configure an interface by entering the following
command: SanJose(config)# ip address 192.168.2.1 255.255.255.0. The command is
rejected by the device. What is the reason for this? - ANS-The command is being
entered from the wrong mode of operation.
An administrator uses the Ctrl-Shift-6 key combination on a switch after issuing the ping
command. What is the purpose of using these keystrokes? - ANS-To interrupt the ping
process.
Refer to the exhibit. A network administrator is configuring access control to switch
SW1. If the administrator uses a console connection to connect to the switch, which
password is needed to access user EXEC mode? - ANS-lineconin
On which switch interface would an administrator configure an IP address so that the
switch can be managed remotely? - ANS-VLAN 1
What protocol is responsible for controlling the size of segments and the rate at which
segments are exchanged between a web client and a web server? - ANS-TCP
What is an advantage to using a protocol that is defined by an open standard? - ANS-It
encourages competition and promotes choices.
What are two benefits of using a layered network model? (Choose two.) - ANS-It assists
in protocol design.
It prevents technology in one layer from affecting other layers.
Which two OSI model layers have the same functionality as two layers of the TCP/IP
model? (Choose two.) - ANS-Network
Transport
Which name is assigned to the transport layer PDU? - ANS-Segment
A network administrator is troubleshooting connectivity issues on a server. Using a
tester, the administrator notices that the signals generated by the server NIC are
distorted and not usable. In which layer of the OSI model is the error categorized? -
ANS-Physical Layer
A network administrator is measuring the transfer of bits across the company backbone
for a mission critical financial application. The administrator notices that the network
throughput appears lower than the bandwidth expected. Which three factors could
influence the differences in throughput? (Choose three.) - ANS-The amount of traffic
that is currently crossing the network.
The type of traffic that is crossing the network.
