a router

A hybrid cloud is made up of two or more clouds (example: part private, part public), where each part remains a distinct object, but both are connected using a single architecture

Hybrid clouds

These identify fast-spreading threats, such as zero-day or zero-hour attacks.

IPS (Intrusion prevention systems)

This attack steals the login credentials of a user in order to access private data.

Identity theft

Interface

What type of network must a home user access in order to do online shopping?

Internet

What is the Internet?

It provides connections through interconnected global networks.

Which network infrastructure provides access to users and end devices in a small geographical area, which is typically a network in a department in an enterprise, a home, or small business?

LAN (Local Area Network)

When designers follow accepted standards and protocols, which of the four basic characteristics of network architecture is achieved?

Security

These are types of software which are installed on a user's device. The software then secretly collects information about the user.

Spyware and adware

What are two functions of end devices on a network? (Choose two.)

They are the interface between humans and the communication network., They originate the data that flows through the network.

WISP stand For

Wireless internet service provider

Which option describes a network attack that occurs on the first day that a vulnerability becomes known?

Zero Day or Zero Hour

Also called zero-hour attacks, these occur on the first day that a vulnerability becomes known.

Zero-day attacks

In which scenario would the use of a WISP be recommended?

a farm in a rural area without wired broadband access

CIA stands for

Confidentiality, Integrity, Availability

A malicious person attacks user devices or network resources.

Threat actor attack

These further filter access and traffic forwarding based on IP addresses and applications.

ACL (Access control lists)

These applications help to protect end devices from becoming infected with malicious software.

Antivirus and antispyware

Which feature describes using personal tools to access information and communicate across a business or campus network?

BYOD (Bring Your Own Device)

A large corporation has modified its network to allow users to access network resources from their personal laptops and smart phones. Which networking trend does this describe?

BYOD (bring your own device)

How does BYOD change the way in which businesses implement networks?​

BYOD Provides flexibility in where and how users can access network resources

Which feature contains options such as Public, Private, Custom and Hybrid?

Cloud Computing

A community cloud is created for exclusive use by specific entities or organizations. The differences between public clouds and community clouds are the functional needs that have been customized for the community.

Community clouds

Which attack slows down or crashes equipment and programs?

DOS (Denial of Service)

This attack captures private information from an organization's network

Data interception and theft

These provide more advanced firewall capabilities that can filter large amounts of traffic with more granularity.

Dedicated firewall systems

These attacks slow or crash applications and processes on a network device.

Denial of service attacks

Which network infrastructure might an organization use to provide secure and safe access to individuals who work for a different organization but require access to the organization's data?

Extranet

Which term refers to a network that provides secure access to the corporate offices by suppliers, customers and collaborators?

Extranet

Having multiple paths to a destination is known as redundancy. This is an example of which characteristic of network architecture?

Fault Tolerance

four basic characteristics that network architects must address to meet user expectations:

Fault Tolerance, Scalability, Quality of Service (QoS), Security

When data is encoded as pulses of light, which media is being used to transmit the data?

Fiber-Optic Cable

Which option blocks unauthorized access to your network?

Firewall

Firewall filtering blocks unauthorized access into and out of the network. This may include a host-based firewall system that prevents unauthorized access to the end device, or a basic filtering service on the home router to prevent unauthorized access from the outside world into the network.

Firewall filtering

Which type of network topology lets you see which end devices are connected to which intermediary devices and what media is being used?

Logical Topology

Which connection physically connects the end device to the network?

NIC ( Network Interface Card)

Which type of network topology lets you see the actual location of intermediary devices and cable installation?

Physical Topology

Which feature is being used when connecting a device to the network using an electrical outlet?

Powerline

Cloud-based applications and services offered in a private cloud are intended for a specific organization or entity, such as a government

Private clouds

Cloud-based applications and services offered in a public cloud are made available to the general population

Public clouds

4 Cloud Types are

Public clouds, Private clouds, Hybrid clouds,Community clouds

With which type of policy, a router can manage the flow of data and voice traffic, giving priority to voice communications if the network experiences congestion?

QoS (Quality of Service)

When designers follow accepted standards and protocols, which of the four basic characteristics of network architecture is achieved?

Scalability

An employee wants to access the network of the organization remotely, in the safest possible way. What network feature would allow an employee to gain secure remote access to a company network?

VPN

Which option creates a secure connection for remote workers?
