when exploring the k-means clustering of a data set you examine the projections of the first two principle component of the cluster ellipses, for a certain number of clusters, and you observe: * the major and minor axes of each of the ellipses are of distinctly different length. * the directions of major axes of the ellipses are distinctly different. which of the following statements is true? a. the number of clusters chosen is too many for this dataset and should be reduced. b. the number of clusters chosen fits this dataset well. c. clustering is not a useful method for this dataset. d. the clusters will exhibit a poor separation

Answers

Answer 1

The number of clusters chosen fits this dataset well when exploring K-means. The correct answer is b.

Cluster analysis is a class of techniques for identifying objects or individuals that are related or related to each other. K-means clustering, the most popular technique, is used to classify objects into K-numbered clusters in a data set. It is used in statistics, bioinformatics, computer science, marketing, and many other fields.K-means clustering of a data set involves examining the projections of the first two principle components of the cluster ellipses for a certain number of clusters. When the number of clusters chosen fits the dataset well, then it implies that the projections of the first two principle components of the cluster ellipses, for a certain number of clusters, shows that the major and minor axes of each of the ellipses are of distinctly different length, and the directions of major axes of the ellipses are distinctly different.In other words, when the projections of the first two principle components of the cluster ellipses, for a certain number of clusters, show that the major and minor axes of each of the ellipses are of distinctly different length and the directions of major axes of the ellipses are distinctly different, then it means that the number of clusters chosen fits this dataset well.The correct answer is b.

you work at a large department store selling computer products. iwina walks in and wants to buy a wireless router. she explains that the media streaming device she ordered online supports a transmission speed of up to 200 mbps. what type of router should you recommend?

Answers

If Iwina's media streaming device supports a transmission speed of up to 200 Mbps, I would recommend a wireless router that supports at least 802.11n wireless standard.

What is a 802.11n wireless standard?

802.11n is a wireless networking standard that operates on both the 2.4 GHz and 5 GHz frequency bands. It offers higher speeds and greater range compared to earlier wireless standards, and is commonly used in home and small business networks.

Thus, if Iwina's media streaming device supports a transmission speed of up to 200 Mbps, I would recommend a wireless router that supports at least 802.11n wireless standard. This wireless standard supports a theoretical maximum speed of up to 600 Mbps, which should provide enough bandwidth to support Iwina's device. Alternatively, a router that supports the newer 802.11ac wireless standard could also be considered, as it offers even higher theoretical speeds.

you are the administrator for the westsim domain. organizational units (ous) have been created for each company department. user and computer accounts for each department have been moved into their respective department ous.

Answers

As an administrator for the Westsim domain, the Organizational Units (OUs) have been created for each company department. All user and computer accounts for each department have been moved into their respective department OUs.

An Organizational Unit (OU) is a container object within an Active Directory that can contain other objects, including other OUs. OUs are created to facilitate the administration of users, computers, and other directory objects. An OU can have policies and permissions applied to it that are distinct from those of other OUs. These containers organize objects within the AD, making it simpler to implement administrative assignments and deploy Group Policy Objects (GPOs). What is Active Directory (AD)?Active Directory (AD) is a directory service that is utilized in Windows environments to centrally manage authentication and authorization for users, computers, and other network resources. It works by combining information about user accounts, computer accounts, and other resources into a central database.

Answers

The correct answer is TCP and UDP are two transport layer protocols that are used for sending data over a network. The following three statements correctly describe their functions:

The TCP source port number identifies the sending host on the network: TCP uses a 16-bit source port field to identify the sending process or application on the host. This helps the receiving host to identify the source of the data. UDP segments are encapsulated within IP packets for transport across the network: UDP does not have any built-in error recovery mechanism, so it simply encapsulates its segments within IP packets and sends them over the network. The source port field identifies the running application or service that will handle data returning to the PC establishing a session with the server: Both TCP and UDP use the source and destination port fields to identify the applications or services that will handle the data. The source port field helps the server to identify the process or application that sent the data and establish a session with the PC. In summary, TCP and UDP are transport layer protocols that use source and destination port numbers to identify the sending and receiving hosts and the applications or services that will handle the data. UDP simply encapsulates its segments within IP packets, while TCP establishes a reliable, connection-oriented session between the hosts.
