Which of the following policies should be adopted to help reduce increasing congestion caused by devices attempting to resend lost packets too quickly or too often?
Retransmission policy
Window policy
Discarding policy
Admission policy
The retransmission policy should be adopted to help reduce the increasing congestion caused by devices attempting to resend lost packets too quickly or too often.
A retransmission policy is a technique that requires the sending of packets until an acknowledgment is received from the receiver. When a packet is sent, it is kept in the queue until an acknowledgment is obtained. If no acknowledgment is obtained, the packet is considered lost and is retransmitted.
This cycle of sending and resending packets causes congestion in the network. As a result, the retransmission policy should be implemented to reduce congestion caused by devices that attempt to resend lost packets too frequently or too quickly.
The issue of too many packets present in the network at the same time, slowing data transmission and affecting the quality of service, is known as congestion. Congestion causes packet loss, slows data transmission, and lowers service quality, which affects the user experience. The following are some common sources of network congestion:
Too much traffic in the network.Failure to keep up with traffic spikes.Network devices' processing power is limited.Poor network design.Packet loss occurs when one or more packets of data traveling through a network do not reach their intended destination. It may be caused by network congestion, poor network design, hardware failure, or packet corruption. When packet loss occurs, the data contained in the packet must be resent, resulting in increased network traffic, delays, and poor service quality.

what propagation technique where a stem is placed in contact with media or soil and allowed to root?
Stem cutting propagation, or simply "stem propagation," is the method of propagation in which a stem is placed in touch with media or soil and allowed to root.
In the process of stem cutting propagation, a healthy plant's stem cutting is removed and placed in a rooting media or soil where it can establish roots and become a new plant. In horticulture, this method is frequently used to multiply attractive plants like roses, lavender, and mint. The cutting may comprise one or more nodes where leaves arise from the stem and is normally taken from the parent plant using a sharp, sterile tool. The stem cutting can develop roots and eventually develop into a new plant that is genetically similar to the parent plant under the right circumstances, such as adequate soil moisture and light. This method is well-liked because it's reasonably easy and affordable.

A systems administrator wants to conduct a scan to identify which services are open on their machines in an attempt to try to disable unused services. Which of the following should they perform?
Question options:
- UDP scan
- NSE scan
- TCP scan
- OS scan
- Ping scan / sweep
The correct answer is To identify which services are open on their machines and disable unused services, the systems administrator should perform a TCP scan.
A TCP scan is a type of port scan that uses the Transmission Control Protocol (TCP) to check whether a port is open or closed. By scanning TCP ports, the systems administrator can identify which services are running on their machines and determine which ones are not being used, allowing them to disable any unnecessary services and improve the security and performance of their system. A UDP scan, on the other hand, is used to identify open User Datagram Protocol (UDP) ports, which are often used for non-critical services that do not require a reliable connection. An NSE (Nmap Scripting Engine) scan is used to gather additional information about the target system, while an OS scan is used to identify the operating system running on the target system. A ping scan/sweep is used to check whether a host is up or down. In summary, the systems administrator should perform a TCP scan to identify which services are open on their machines and disable any unused services to improve the overall security and performance of their system.

The syntax rules for the SPL language should be defined using EBNF notations.
What is the purpose of creating a lexical analyzer for the SPL language?
The SPL language is a small programming language that requires a lexical analyzer, parser, and interpreter to function. The lexical analyzer is the first component in this process, and its purpose is to analyze the input program and break it down into smaller tokens that can be used by the parser.
The lexical analyzer for the SPL language should be designed to identify and differentiate between different types of tokens, such as keywords, identifiers, constants, and operators. Keywords are reserved words that have a predefined meaning in the SPL language, while identifiers are used to define variable and function names.
Constants in the SPL language can be integer, Boolean, or string literals, and they are used to represent fixed values that do not change during program execution. Operators in the SPL language are used to perform operations on different types of data, such as assignment (=), comparison operators (== and !=), and logical operators (not, or, and).
The extended Backus-Naur form (EBNF) is used to define the syntax rules for the SPL language. The syntax rules define the structure and organization of the language constructs and specify how different tokens can be combined to form valid SPL programs.
In summary, the purpose of creating a lexical analyzer for the SPL language is to break down the input program into smaller tokens that can be used by the parser to generate a parse tree. The lexical analyzer should be designed to identify different types of tokens, such as keywords, identifiers, constants, and operators, and the syntax rules for the SPL language should be defined using EBNF notations.

Your firm has recently converted its purchasing cycle from a manual process to an online computer system. Which of the following is a probable result associated with conversion to the new automatic system?A. Processing time is increased.B. The firm's risk exposures are reduced.C. Traditional duties are less segregated.D. Processing errors are increased.
The probable result associated with conversion to the new automatic system is that "traditional duties are less segregated." Option C is correct.
When a firm converts its purchasing cycle from a manual process to an online computer system, the traditional segregation of duties may be disrupted. This is because the new system may centralize tasks and responsibilities that were previously segregated among different individuals or departments.
For example, the new system may allow a single individual to initiate, approve, and execute a purchase transaction. This increases the risk of fraud or errors as there are fewer checks and balances in place.
Therefore, it is important to establish appropriate controls and monitoring mechanisms to mitigate the risk of fraud or errors and ensure that the segregation of duties is maintained in the new system. Option C holds true.

81.0% complete question a cloud administrator deploys two cloud servers on the amazon web services (aws) platform, each in a separately defined virtual network. how does the administrator get both servers to communicate with each other without using an internet gateway?
The cloud administrator gets both servers to communicate with each other without using an internet gateway by creating a VPC Peering Connection between the two virtual networks.
What is VPC! Virtual Private Cloud (VPC) is a virtual network that enables the user to launch AWS resources into a virtual network that the user has defined. It helps in providing complete control over the virtual networking environment such as the selection of IP address range, creation of subnets, and configuration of route tables & network gateways. VPC Peering Connection VPC Peering Connection is a network connection that enables the user to route traffic between two VPCs in the same region using private IP addresses. It makes it easy to connect VPCs that are part of a similar account or are owned by different accounts within the same region. Also, VPC peering is possible across multiple accounts as long as they are within the same region. Here are the steps to create VPC Peering Connection:
Step 1: Log in to your AWS account.
Step 2: Go to the VPC console.
Step 3: Select Peering Connections and then Create Peering Connection.
Step 4: Fill out the form. You'll need to enter the ID of the VPC that you're peering with.
Step 5: Click Create Peering Connection. Your VPC Peering Connection is now created.
The user can now establish a VPC Peering Connection between the two virtual networks to enable the servers to communicate with each other.

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
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.
