You work for manufacturing company who operate a hybrid infrastructure with systems located both in a local Datacentre and in AW

S, connected via Direct Connect. Currently, all on premise servers are backed up to a local NAS, but your CTO wants you decide on the best way to store copies of these backups in AWS. He has asked you to propose a solution which will provide access to the files within milliseconds should they be needed, but at the same time minimizes cost. As these files will be copies of backups stored on-premise, availability is not as critical as durability. Choose the best option from the following which meets the brief.
Copy the files from the NAS to an S3 bucket configured as Standard class.
Copy the files to an EC2 instance with a large EBS volume attached.
Copy the files from the NAS to an S3 bucket with the Reduced Redundancy Storage class.
Copy the files from the NAS to an S3 bucket with the One Zone-IA class

Answer: Copy the files from the NAS to an S3 bucket with the One Zone-IA class

Explanation:

Th one Zone -IA class with S3 bucket has reduced cost but offers the same durability for which the files needs to be copied from NAS to access them faster.

The association between a UCS and a CS can be extended to include more stimuli (more stimuli related to the CS can elicit the CR
almond37 [142]

Answer:

The answer is Stimulus generalization

Explanation:

Stimulus generalization is an example of classical condition. Classical conditioning takes a stimulus that does not cause a particular response (neutral stimulus) and then pairs it repeatedly with an unconditioned stimulus that will cause an unconditioned response. In the case of Stimulus generalization, I will give an example of a subject presenting food to a dog once they ring a bell. Lets say that you have taught a dog to salivate every time it hears a bell ring. If you took another bell that has a similar sound and rang it, the dog would still salivate and come pick its food. This is a perfect example of Stimulus generalization. The dog has responded to a new stimulus as if it was the initial conditioned stimulus.

Assume a TCP sender is continuously sending 1,090-byte segments. If a TCP receiver advertises a window size of 5,718 bytes, and
Arturiano [62]

Answer:

for the 5 segments, the utilization is 3.8%

Explanation:

Given the data in the question;

segment size = 1090 bytes

Receiver window size = 5,718 bytes

Link transmission rate or Bandwidth = 26 Mbps = 26 × 10⁶ bps

propagation delay = 22.1 ms

so,

Round trip time = 2 × propagation delay = 2 × 22.1 ms = 44.2 ms

we determine the total segments;

Total segments = Receiver window size / sender segment or segment size

we substitute

Total segments = 5718 bytes / 1090 bytes

Total segments = 5.24587 ≈ 5

Next is the throughput

Throughput = Segment / Round trip

Throughput = 1090 bytes / 44.2 ms

1byte = 8 bits and 1ms = 10⁻³ s

Throughput = ( 1090 × 8 )bits / ( 44.2 × 10⁻³ )s

Throughput = 8720 bits / ( 44.2 × 10⁻³ s )

Throughput = 197.285 × 10³ bps

Now Utilization will be;

Utilization = Throughput / Bandwidth

we substitute

Utilization = ( 197.285 × 10³ bps ) / ( 26 × 10⁶ bps )

Utilization = 0.0076

Utilization is percentage will be ( 0.0076 × 100)% = 0.76%

∴ Over all utilization for the 5 segments will be;

⇒ 5 × 0.76% = 3.8%

Therefore, for the 5 segments, the utilization is 3.8%

Explain any one method of creating a presentation.
Arisa [49]

Answer:

Step 1: Analyze your audience

The first step in preparing a presentation is to learn more about the audience to whom you'll be speaking. It's a good idea to obtain some information on the backgrounds, values, and interests of your audience so that you understand what the audience members might expect from your presentation.

Step 2: Select a topic

Next, if possible select a topic that is of interest to the audience and to you. It will be much easier to deliver a presentation that the audience finds relevant, and more enjoyable to research a topic that is of interest to you.

Step 3: Define the objective of the presentation

Once you have selected a topic, write the objective of the presentation in a single concise statement. The objective needs to specify exactly what you want your audience to learn from your presentation. Base the objective and the level of the content on the amount of time you have for the presentation and the background knowledge of the audience. Use this statement to help keep you focused as you research and develop the presentation.

Preparing the Content of Your Presentation

Step 4: Prepare the body of the presentation

After defining the objective of your presentation, determine how much information you can present in the amount of time allowed. Also, use your knowledge about the audience to prepare a presentation with the right level of detail. You don't want to plan a presentation that is too basic or too advanced.

The body of the presentation is where you present your ideas. To present your ideas convincingly, you will need to illustrate and support them. Strategies to help you do this include the following:

Present data and facts

Read quotes from experts

Relate personal experiences

Provide vivid descriptions

And remember, as you plan the body of your presentation it's important to provide variety. Listeners may quickly become bored by lots of facts or they may tire of hearing story after story.

Step 5: Prepare the introduction and conclusion

Once you've prepared the body of the presentation, decide how you will begin and end the talk. Make sure the introduction captures the attention of your audience and the conclusion summarizes and reiterates your important points. In other words, "Tell them what you're going to tell them. Tell them. Then, tell them what you told them."

During the opening of your presentation, it's important to attract the audience's attention and build their interest. If you don't, listeners will turn their attention elsewhere and you'll have a difficult time getting it back. Strategies that you can use include the following:

Make the introduction relevant to the listeners' goals, values, and needs

Ask questions to stimulate thinking

Share a personal experience

Begin with a joke or humorous story

Project a cartoon or colorful visual

Make a stimulating or inspirational statement

Give a unique demonstration

During the opening you want to clearly present your topic and the purpose of your presentation. Clearly articulating the topic and purpose will help the listeners focus on and easily follow your main ideas.

During the conclusion of your presentation, reinforce the main ideas you communicated. Remember that listeners won't remember your entire presentation, only the main ideas. By reinforcing and reviewing the main ideas, you help the audience remember them.

Practicing and Delivering

Step 6: Practice delivering the presentation

Most people spend hours preparing a presentation but very little time practicing it. When you practice your presentation, you can reduce the number of times you utter words and phrases like, "um," "well," and "you know." These habits can easily diminish a speaker's credibility. You can also fine-tune your content to be sure you make your most important points in the time alloted.

In addition to planning the content of your presentation, you need to give advanced thought to how you want to deliver it. Do you want to commit your presentation to memory, use cards to guide you, or read from a script? Or, you might want to use a combination of methods. To help you decide, read the advantages and disadvantages of the four delivery methods described below.
