What is a characteristic of a fault tolerant network?
a network that recovers quickly when a failure occurs and depends on redundancy to limit the impact of a failure
a network that can expand quickly to support new users and applications without impacting the performance of the service delivered to existing users
a network that protects confidential information from unauthorized access
a network that supports a mechanism for managing congestion and ensuring reliable delivery of content to all users
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?
audio conference, financial transactions, web page
financial transactions, web page, audio conference
audio conference, financial transactions, web page
What is a benefit of using cloud computing in networking?
Network capabilities are extended without requiring investment in new infrastructure, personnel, or software
End users have the freedom to use personal tools to access information and communicate across a business network
Technology is integrated into every-day appliances allowing them to interconnect with other devices, making them more ‘smart’ or automated.

What is the function of the shell in an OS
It provides the intrusion protection services for the device
It interfaces between the users and the kernel
It provides dedicated firewall services
It interfaces between the users and the kernel
Which connection provides a secure CLI session with encryption to a Cisco switch?
an SSH connection
a console connection
a Telnet connection
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?
The command syntax is wrong
The command is being entered from the wrong mode of operation
The interface is shutdown and must be enabled before the switch will accept the IP address
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
to restart the ping proces
to allow the user to complete the command
to interrupt the ping process
to exit to a different configuration mode
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?
pytanie 8
On which switch interface would an administrator configure an IP address so that the switch can be managed remotely?
console 0
VLAN 1
FastEthernet0/1
vty 0
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?
TCP
Ethernet
IP
HTTP
TCP
What is an advantage to using a protocol that is defined by an open standard?
A company can monopolize the market.
It encourages competition and promotes choices
The protocol can only be run on equipment from a specific vendor.
An open standard protocol is not controlled or regulated by standards organizations.
It encourages competition and promotes choices
What are two benefits of using a layered network model? (Choose two.)
It prevents designers from creating their own model.
It speeds up packet delivery.
It ensures a device at one layer can function at the next higher layer
It prevents technology in one layer from affecting other layers.
It assists in protocol design.
It prevents technology in one layer from affecting other layers.
It assists in protocol design.
Which two OSI model layers have the same functionality as two layers of the TCP/IP model? (Choose two.)
physical
session
network
transport
data link
network
transport
Which name is assigned to the transport layer PDU?
segment
frame
bits
segment
A network engineer is measuring the transfer of bits across the company backbone for a mission critical database application. The engineer notices that the network throughput appears lower than the bandwidth expected. Which three factors could influence the differences in throughput? (Choose three.)
the amount of traffic that is currently crossing the network*
the sophistication of the encapsulation method applied to the data
the bandwidth of the WAN connection to the Internet
the type of traffic that is crossing the network
the latency that is created by the number of network devices that the data is crossing
the reliability of the gigabit Ethernet infrastructure of the backbone
the amount of traffic that is currently crossing the network*
the type of traffic that is crossing the network
the latency that is created by the number of network devices that the data is crossing
