Question 6

Which infrastructure-centric metric measures the down-time of an information system?
A) Accuracy
B) Throughput
C) System availability
D) System downtown

Accepted Answer

System availability is the metric that measures the percentage of time that an information system is operational and available for use.

Question 9

Which infrastructure-centric metric measures the error rate or the number of errors per thousand (or million) that an information system generates?
A) Accuracy
B) Throughput
C) Scalability
D) Critical success factor

Accepted Answer

Accuracy measures the error rate or the number of errors per thousand (or million) that an information system generates. Throughput measures the amount of data that is transferred in a given period of time. Scalability measures how well a system can handle increased demands in terms of performance and capacity. Critical success factor is a strategic goal or objective that must be achieved for an organization to be successful.

Question 10

Which infrastructure-centric metric measures the speed at which a system can process a transaction?
A) Transaction speed
B) Accuracy
C) Throughput
D) Reaction time

Accepted Answer

Question 11

If you were working in an environment where each IT system was partitioned into layers and each layer performed a specific function, what type of infrastructure would you be using?
A) Distributed
B) Tiered
C) Decentralized
D) Client/server

Accepted Answer

The scenario described is that of a tiered infrastructure, where IT systems are divided into layers, with each layer performing a specific function. This approach is commonly used in enterprise environments to improve scalability, reliability, and maintainability. Distributed and decentralized infrastructures refer to different approaches to organizing IT resources and are not applicable in this scenario. Client/server refers to a specific model of distributed computing where clients request resources or services from servers, again not applicable to the scenario described.

Question 12

What is a baseline value that a system seeks to attain?
A) Benchmark
B) Milestone
C) Quality measures
D) Criterion

Accepted Answer

A baseline value is a benchmark or standard that a system seeks to attain. It serves as a reference point for evaluating progress and determining success or failure. Milestones are specific achievements or events that mark significant progress toward a goal. Quality measures are methods for assessing the level of quality in a system or process. Criteria are standards or requirements for determining success or failure. Out of these options, benchmark is the only one that matches the definition of a baseline value.

Question 13

If you were working in Calgary, Alberta and all of your ERP application ran from a computer located in Mississauga, Ontario you would be using a _____ infrastructure.
A) Client/server
B) Centralized
C) Decentralized
D) Distributed

Accepted Answer

If the ERP application is running from a computer located in another province, it implies that the infrastructure is distributed. This means that the components of the application are spread across multiple locations, and communication occurs over a network.

Question 14

In what type of tiered infrastructure do all the computing resources sit on one computer?
A) 1-tier
B) 2-tier
C) 3-tier
D) 4-tier

Accepted Answer

In a 1-tier infrastructure, all the computing resources sit on one computer. This is also known as a monolithic architecture.

Question 15

Which infrastructure-centric metric measures the amount of information that can pass through a system in a given amount of time?
A) Transaction speed
B) Accuracy
C) Throughput
D) Bandwidth

Accepted Answer

Throughput is the infrastructure-centric metric that measures the amount of information that can pass through a system in a given amount of time. Transaction speed refers to the time taken for a single transaction to be processed, accuracy refers to the correctness and precision of the output, and bandwidth refers to the capacity of a network to transmit data.

Question 16

What is the process of continuously measuring system results and comparing those results to values a system seeks to attain?
A) Critical milestones
B) Benchmarking
C) Quality testing
D) Criterion checking

Accepted Answer

The process described in the question is benchmarking. Benchmarking involves measuring a system's performance over time and comparing it to a desired standard or best practice. This allows for continuous improvement and identification of areas for improvement. None of the other choices accurately describe this process.

Question 17

Which metric assesses whether or not some function or task is completed the fastest?
A) Benchmark
B) Effectiveness
C) Efficiency
D) Fitting metrics

Accepted Answer

Efficiency is the metric that assesses the speed of completing a function or task. Benchmark refers to a standard or point of reference, effectiveness measures how well a task achieves its goals, and fitting metrics evaluate how well a model fits a dataset.

Question 18

What type of tiered infrastructure is the most common approach used for Web applications today?
A) 1-tier
B) 2-tier
C) 3-tier
D) 4-tier

Accepted Answer

The 3-tier infrastructure, consisting of presentation, application, and database tiers, is the most common approach used for Web applications today. This structure allows for better scalability, manageability and separation of concerns.

Question 19

What does an infrastructure-centric metric measure?
A) Efficiency
B) Speed
C) Capacity
D) Efficiency, speed, and capacity

Accepted Answer

Infrastructure-centric metrics are designed to measure the efficiency, speed, and capacity of a system's infrastructure, encompassing all these aspects to ensure optimal performance and resource utilization.

Question 20

If your task was to determine if your clothing store demonstrated effectiveness, which of the following activities would you measure?
A) The level of traffic coming into your store
B) The time it takes to process customer's purchases
C) The number of mistakes made by employees working the cash register
D) The number and amount of purchases made by customers who visit the store

Accepted Answer

The number and amount of purchases made by customers who visit the store would demonstrate the effectiveness of the clothing store. If customers are making purchases in the store, it suggests that they find the clothing selection and shopping experience satisfactory. Tracking this metric can help the store assess its overall performance and make necessary improvements. The other options may be important to measure for different reasons, but they do not directly reflect the effectiveness of the store.
