CompTIA Data+ Certification Exam Sample Questions (Q340-Q345):

NEW QUESTION # 340
While reviewing survey data, a research analyst notices data is missing from all the responses to a single question. Which of the following methods would BEST address this issue?

A. Remove duplicate data.
B. Replace missing data.
C. Remove invalid data.
D. Replace redundant data.

Answer: D

NEW QUESTION # 341
Under which of the following circumstances should the null hypothesis be accepted when a = 0.05?

A. When p is 0.00003
B. When p is 0.04
C. When p is 0.06
D. When p is 0.001

Answer: B

Explanation:
The null hypothesis should be accepted when the p-value is greater than the alpha level, which is the significance level of the test. The p-value is the probability of obtaining a test statistic at least as extreme as the one observed in the sample, assuming that the null hypothesis is true. The alpha level is the probability of rejecting the null hypothesis when it is true, which is also known as a type I error12.
In this case, the alpha level is 0.05, which means that there is a 5% chance of rejecting the null hypothesis when it is true. Therefore, to reject the null hypothesis, the p-value must be less than or equal to 0.05, which indicates that the test statistic is very unlikely to occur by chance under the null hypothesis. Conversely, to accept the null hypothesis, the p-value must be greater than 0.05, which indicates that the test statistic is not very unlikely to occur by chance under the null hypothesis.
Among the four options, only option D has a p-value that is greater than 0.05 (p = 0.06). Therefore, option D is the correct answer. When p = 0.06, it means that there is a 6% chance of obtaining a test statistic at least as extreme as the one observed in the sample, assuming that the null hypothesis is true. This probability is not very low, and therefore does not provide enough evidence to reject the null hypothesis.

NEW QUESTION # 342
A site reliability team wants to monitor the stability of their website. so they can proactively diagnose issues when they occur Which of the following deliverables would best suit their needs?

A. A weekly log report of site visits and user actions
B. A portal that is refreshed daily and reports errors classified by type
C. A self-serve dashboard of website performance that updates in real time
D. A daily summary email indicating website outages for the previous day

Answer: C

Explanation:
The best deliverable that would suit the site reliability team's needs is A) A self-serve dashboard of website performance that updates in real time.
A self-serve dashboard is a visual display of the most important information needed to achieve one or more objectives, consolidated and arranged on a single screen so the information can be monitored at a glance. A self-serve dashboard of website performance that updates in real time would allow the site reliability team to easily and quickly access the information they need about the stability of their website, such as uptime, response time, error rate, traffic volume, etc. A self-serve dashboard would also enable the team to proactively diagnose issues when they occur, by providing alerts, notifications, or drill-down options. A self-serve dashboard would also be more interactive and engaging than a report or an email.
A weekly log report of site visits and user actions would not be a good deliverable for the site reliability team's needs, because it would not provide timely or relevant information about the stability of their website. A weekly log report would be too infrequent and delayed to monitor and diagnose issues when they occur. A weekly log report would also focus on the behavior and actions of the users, rather than the performance and functionality of the website.
A portal that is refreshed daily and reports errors classified by type would not be a good deliverable for the site reliability team's needs, because it would not provide real-time or comprehensive information about the stability of their website. A portal that is refreshed daily would be too slow and outdated to monitor and diagnose issues when they occur. A portal that reports errors classified by type would be too narrow and limited to capture the full picture of the website performance.
A daily summary email indicating website outages for the previous day would not be a good deliverable for the site reliability team's needs, because it would not provide real-time or actionable information about the stability of their website. A daily summary email would be too late and retrospective to monitor and diagnose issues when they occur. A daily summary email indicating website outages would also be too passive and generic to help the team resolve or prevent issues in the future.
