What is a characteristic of a fault tolerant network?

a network that protects confidential information from unauthorized access
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 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

Explanation:

Fault tolerant networks limit the impact of a failure because the networks are built in a way that allows for quick recovery when such a failure occurs. These networks depend on multiple or redundant paths between the source and destination of a message.
A scalable network can expand quickly to support new users and applications without impacting the performance of the service being delivered to existing users.
Quality of service (QoS) is a mechanism for managing congestion and ensuring reliable delivery of content to all users.

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, web page, financial transactions

financial transactions, audio conference, web page

Explanation:

QoS mechanisms enable the establishment of queue management strategies that enforce priorities for different categories of application data. Thus, this queuing enables voice data to have priority over transaction data, which has priority over web data.

What is a benefit of using cloud computing in networking?

End users have the freedom to use personal tools to access information and communicate across a business network.
Network capabilities are extended without requiring investment in new infrastructure, personnel, or software.
Technology is integrated into every-day appliances allowing them to interconnect with other devices, making them more ‘smart’ or automated.

Home networking uses existing electrical wiring to connect devices to the network wherever there is an electrical outlet, saving the cost of installing data cables.

Explanation:

Cloud computing extends IT’s capabilities without requiring investment in new infrastructure, training new personnel, or licensing new software. These services are available on-demand and delivered economically to any device anywhere in the world without compromising security or function. BYOD is about end users having the freedom to use personal tools to access information and communicate across a business or campus network. Smart home technology is integrated into every-day appliances allowing them to interconnect with other devices, making them more ‘smart’ or automated. Powerline networking is a trend for home networking that uses existing electrical wiring to connect devices to the network wherever there is an electrical outlet, saving the cost of installing data cables.

What is the function of the shell in an OS?
- It interacts with the device hardware.
- It interfaces between the users and the kernel.
- It provides dedicated firewall services.
- It provides the intrusion protection services for the device.
  
  Explanation:
  
  Most operating systems contain a shell and a kernel. The kernel interacts with the hardware and the shell interfaces between the kernel and the users.

Which connection provides a secure CLI session with encryption to a Cisco switch?

a console connection
an AUX connection
a Telnet connection

an SSH connection

Explanation:

A CLI session using Secure Shell (SSH) provides enhanced security because SSH supports strong passwords and encryption during the transport of session data. The other methods support authentication but not encryption.

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 is being entered from the wrong mode of operation.
The command syntax is wrong.
The subnet mask information is incorrect.

The interface is shutdown and must be enabled before the switch will accept the IP address.

Explanation:

The wrong mode of operation is being used. The CLI prompt indicates that the mode of operation is global configuration. IP addresses must be configured from interface configuration mode, as indicated by the SanJose(config-if)# prompt.

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 process
to interrupt the ping process
to exit to a different configuration mode

to allow the user to complete the command

Explanation:

To interrupt an IOS process such as ping or traceroute, a user enters the Ctrl-Shift-6 key combination. Tab completes the remainder of parameters or arguments within a command. To exit from configuration mode to privileged mode use the Ctrl-Z keystroke. CTRL-R will redisplay the line just typed, thus making it easier for the user to press Enter and reissue the ping command.

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?

Cisco ITN CCNA 1 v6.0 Final Exam Answer R&S 2018 2019 001

letmein
secretin
lineconin

linevtyin

Explanation:

Telnet accesses a network device through the virtual interface configured with the line VTY command. The password configured under this is required to access the user EXEC mode. The password configured under the line console 0 command is required to gain entry through the console port, and the enable and enable secret passwords are used to allow entry into the privileged EXEC mode.

On which switch interface would an administrator configure an IP address so that the switch can be managed remotely?

FastEthernet0/1
VLAN 1
vty 0

console 0

Explanation:

Interface VLAN 1 is a virtual interface on a switch, called SVI (switch virtual interface). Configuring an IP address on the default SVI, interface VLAN 1, will allow a switch to be accessed remotely. The VTY line must also be configured to allow remote access, but an IP address cannot be configured on this line.

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
IP
HTTP

Ethernet

Explanation:

TCP is a Layer 4 protocol of the OSI model. TCP has several responsibilities in the network communication process. It divides large messages into smaller segments which are more efficient to send across the network. It also controls the size and rate of segments exchanged between clients and servers.

What is an advantage to using a protocol that is defined by an open standard?

A company can monopolize the market.
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.

Explanation:

A monopoly by one company is not a good idea from a user point of view. If a protocol can only be run on one brand, it makes it difficult to have mixed equipment in a network. A proprietary protocol is not free to use. An open standard protocol will in general be implemented by a wide range of vendors.

What are two benefits of using a layered network model? (Choose two.)

It assists in protocol design.
It speeds up packet delivery.
It prevents designers from creating their own model.
It prevents technology in one layer from affecting other layers.

It ensures a device at one layer can function at the next higher layer.

Explanation:

Some vendors have developed their own reference models and protocols. Today, if a device is to communicate on the Internet, the device must use the TCP/IP model. The benefits of using a layered model are as follows:

assists in protocol design
fosters competition between vendors
prevents a technology that functions at one layer from affecting any other layer
provides a common language for describing network functionality
helps in visualizing the interaction between each layer and protocols between each layer

Which two OSI model layers have the same functionality as two layers of the TCP/IP model? (Choose two.)

data link
network
physical
session

transport

Explanation:

The OSI transport layer is functionally equivalent to the TCP/IP transport layer, and the OSI network layer is equivalent to the TCP/IP internet layer. The OSI data link and physical layers together are equivalent to the TCP/IP network access layer. The OSI session layer (with the presentation layer) is included within the TCP/IP application layer.

Which name is assigned to the transport layer PDU?

bits
data
frame
packet

segment

Explanation:

Application data is passed down the protocol stack on its way to be transmitted across the network media. During the process, various protocols add information to it at each level. At each stage of the process, a PDU (protocol data unit) has a different name to reflect its new functions. The PDUs are named according to the protocols of the TCP/IP suite:

Data – The general term for the PDU used at the application layer.
Segment – transport layer PDU
Packet – network layer PDU
Frame – data link layer PDU
Bits – A physical layer PDU used when physically transmitting data over the medium

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?

presentation layer
network layer
physical layer

data link layer

Explanation:

The NIC has responsibilities in both Layer 1 and Layer 2. The NIC encodes the frame as a series of signals that are transmitted onto the local media. This is the responsibility of the physical layer of the OSI model. The signal could be in the form of electrical, optical, or radio waves.

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.)

the amount of traffic that is currently crossing the network
the sophistication of the encapsulation method applied to the data
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 bandwidth of the WAN connection to the Internet

the reliability of the gigabit Ethernet infrastructure of the backbone

Explanation:

Throughput usually does not match the specified bandwidth of physical links due to multiple factors. These factors include, the amount of traffic, type of traffic, and latency created by the network devices the data has to cross.

What is a characteristic of UTP cabling?

cancellation
cladding
immunity to electrical hazards

woven copper braid or metallic foil

Explanation:

Cladding and immunization from electrical hazards are characteristics for fiber-optic cabling. A woven copper braid or metallic foil is used as a shield for the inner coaxial cable conductor. Cancellation is a property of UTP cabling where two wires are located adjacent to one another so each magnetic field cancels out the adjacent magnetic field.

What are two characteristics of fiber-optic cable? (Choose two.)

It is not affected by EMI or RFI.
Each pair of cables is wrapped in metallic foil.
It combines the technique of cancellation, shielding, and twisting to protect data.
It typically contains 4 pairs of fiber-optic wires.

It is more expensive than UTP cabling is.

Explanation:

Fiber-optic cabling supports higher bandwidth than UTP for longer distances. Fiber is immune to EMI and RFI, but costs more, requires more skill to install, and requires more safety precautions.

What is a characteristic of the LLC sublayer?

It provides the logical addressing required that identifies the device.
It provides delimitation of data according to the physical signaling requirements of the medium.
It places information in the frame allowing multiple Layer 3 protocols to use the same network interface and media.

It defines software processes that provide services to the physical layer.

Explanation:

The Logical Link Control (LLC) defines the software processes that provide services to the network layer protocols. The information is placed by LLC in the frame and identifies which network layer protocol is being used for the frame. This information allows multiple Layer 3 protocols, such as IPv4 and IPv6, to utilize the same network interface and media.

A network team is comparing physical WAN topologies for connecting remote sites to a headquarters building. Which topology provides high availability and connects some, but not all, remote sites?

mesh
partial mesh
hub and spoke

point-to-point

Explanation:

Partial mesh topologies provide high availability by interconnecting multiple remote sites, but do not require a connection between all remote sites. A mesh topology requires point-to-point links with every system being connected to every other system. A point-to-point topology is where each device is connected to one other device. A hub and spoke uses a central device in a star topology that connects to other point-to-point devices.
