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, web page
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
What is the function of the shell in an OS? - ANS-it interfaces between the users and
the kernel.
What is a benefit of using cloud computing in networking? - ANS-Network capabilities
are extended without requiring investment in new infrastructure, personnel, or software.
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
A home user is looking for an ISP connection that provides high speed digital
transmission over regular phone lines. What ISP connection type should be used? -
ANS-DSL
How does quality of service help a network support a wide range of applications and
services? - ANS-by providing mechanisms to manage congested network traffic
On which switch interface would an administrator configure an IP address so that the
switch can be managed remotely? - ANS-VLAN 1
, After making configuration changes on a Cisco switch, a network administrator issues a
copy running-config startup-config command. What is the result of issuing this
command? - ANS-The new configuration will be loaded if the switch is restarted.
Refer to the exhibit. A network administrator is configuring access control to switch
SW1. If the administrator has already logged into a Telnet session on the switch, which
password is needed to access privileged EXEC mode? - ANS-secretin
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-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

entered from the wrong mode of operation.
What function does pressing the Tab key have when entering a command in IOS? -
ANS-It completes the remainder of a partially typed word in a command.
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 layer is responsible for routing messages through an internetwork in the TCP/IP
model? - ANS-internet
Which statement accurately describes a TCP/IP encapsulation process when a PC is
sending data to the network? - ANS-Segments are sent from the transport layer to the
internet layer.
What unique address is embedded in an Ethernet NIC and used for communication on
an Ethernet network? - ANS-MAC address
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
