What is the dotted decimal representation of the IPv4 address which is represented as the binary string 00001010.01100100.00010101.00000001?

10.100.21.1 Converting the binary string of 00001010.01100100.00010101.00000001 to dotted decimal gives 10.100.21.1

How many unique values are possible using a single binary digit?

2

What is the decimal equivalent of the hexadecimal value of 3F?

63

A student is learning number systems. What is the hexadecimal equivalent for the decimal number 165?

A5 Decimal 165 in binary is 10100101. 128+32+4+1 = 165.Each 4 binary digits equates to 1 hexadecimal digit.1010 = 10 (decimal) = A (hexadecimal)0101 = 5 (decimal) = 5 (hexadecimal)

Match the hierarchical design layer with the description.

Access layer- Provides host connectivity to the network Core layer- Provides a high-speed connection for the backbone network Distribution layer - Provides interconnections for smaller local access networks

What is the hexadecimal equivalent for the binary number 10111010?

BA Each 4 binary digits equates to 1 hexadecimal digit.1011 = 11 (decimal) = B (hexadecimal)1010 = 10 (decimal) = A (hexadecimal)

What are two differences between binary and decimal numbers? (Choose two.)

Computing devices use the binary system for data processing and storage. Binary numbers are based on powers of 2 and decimal numbers are based on powers of 10.

Which Cloud computing service would be best for a new organization that cannot afford physical servers and networking equipment and must purchase network services on-demand?

IaaS Infrastructure as a service (IaaS) provides an environment where users have an on-demand infrastructure that they can install any platform as needed.

Which Cloud computing service would be best for an organization that needs to collaboratively create applications and deliver them over the web?

PaaS Platform as a service (PaaS) provides a collaborative environment where multiple developers can create software and host an application through a Cloud provider.

An administrator is adding voice and video service capabilities to an existing network. What design requirement is being satisfied by this situation?

Scalability refers to the ability of a network to expand to support new users, services, and applications. In this example, scalability allows the administrator to expand the ability of the network to support voice and video.

Which layer of the hierarchical design model provides a means of connecting devices to the network and controlling which devices are allowed to communicate on the network?

The access layer in the hierarchical network design provides a connection point for end user devices to the network and allows multiple hosts to connect to other hosts through a network device.

Which is a characteristic of a Type 2 hypervisor?​

Type 2 hypervisors are hosted on an underlaying operating system and are best suited for consumer applications and those experimenting with virtualization. Unlike Type 1 hypervisors, Type 2 hypervisors do not require a management console and do not have direct access to hardware.​

Which statement accurately describes a Type 2 hypervisor?

Type 2 hypervisors run as a software layer atop a host operating system. These hypervisors are often found on PCs and not high-end servers.

Which term describes the state of a network when the demand on the network resources exceeds the available capacity?

congestion. When the demand on the network resources exceeds the available capacity, the network becomes congested. A converged network is designed to deliver multiple communication types, such as data, video and voice services, using the same network infrastructure.

Which IPv4 address format was created for ease of use by people and is expressed as 201.192.1.14?

dotted decimal

A college is building a new dormitory on its campus. Workers are digging in the ground to install a new water pipe for the dormitory. A worker accidentally damages a fiber optic cable that connects two of the existing dormitories to the campus data center. Although the cable has been cut, students in the dormitories only experience a very short interruption of network services. What characteristic of the network is shown here?

fault tolerance Fault tolerance is the characteristic of a network which allows it to quickly respond to failures of network devices, media, or services. Quality of service refers to the measures taken to ensure that network traffic requiring higher throughput receives the required network resources. Scalability refers to the ability of the network to grow to accommodate new requirements. Security refers to protecting networks and data from theft, alteration, or destruction. Integrity refers to the completeness of something and is generally not used as a characteristic of networks in the same way as the other terms.

Which characteristic defines a private cloud?

intended for a specific organization

Which feature relies on prioritization of network traffic and is used to ensure successful delivery of real-time services?

quality of service Quality of Service (QoS) is implemented in networks to prioritize traffic. Traffic for real-time services such as voice and video requires a higher priority than data traffic to ensure reliable delivery of voice and video content to users.

A networking technician is working on the wireless network at a medical clinic. The technician accidentally sets up the wireless network so that patients can see the medical records data of other patients. Which of the four network characteristics has been violated in this situation?

security Network security includes protecting the confidentiality of data that is on the network. In this case, because confidential data has been made available to unauthorized users, the security characteristic of the network has failed.

A company leases a cloud-based payroll system. Which cloud computing technology is this company using?

software as a service (SaaS) Software as a service (SaaS) refers to on demand software that is leased from the provider. Platform as a service (PaaS) is when the provider provides the platform for a developer. Infrastructure as a service (IaaS) is when key network devices such as routers and firewalls are leased from a provider. Wireless as a service (WaaS) is when a provider provides wireless connectivity at a fixed monthly cost.

What is the function of a hypervisor?

to create VMs and provide hardware abstraction to support them A hypervisor is a software process that abstracts the hardware layer from the operating systems allowing multiple virtual machines to run simultaneously.
