How to improve the correct rate in the morning question of network engineer examination

Network Engineer Examination is the National computer technology and software level examination of an intermediate qualification examination, through the examination of qualified personnel in accordance with the requirements of the application Department of network system planning, design and installation of network equipment and hardware debugging work, can carry out network system operation, maintenance and management, can be efficient, reliable, Manage network resources securely, as a network professional to the system development of technical support and guidance, with the actual work ability of engineers and business level, can guide network administrators to engage in network system construction and management work. Network Engineer Exam is a popular soft test, how to pass the exam is the vast number of candidates are want to know, the following Greek soft Test college for you to bring the network engineer exam preparation tips, teach you how to answer questions in the morning to improve the correct rate, to pass the exam successfully.

Network engineer Morning module knowledge structure and answer skills

The morning exam is objective (75 single-choice), the main feature is a wide range of knowledge, inner space, but usually not too much difficulty, so as long as targeted to strengthen the review, through the probability is very large. The following is from the distribution of knowledge points in the exam, the distribution of questions over the years, examination and review points three aspects of analysis, in order to help students from the macro level of the examination of the context and trends, according to their own actual situation to formulate a review plan.

1. Progress

Make sure you do the right thing before you get it easy.

Training intuition, believe that the first judgment, sometimes too much thinking, but prone to error.

Don't spend more than a minute on a problem.

No or unsure, make a mark, jump over, and maybe see the answer from the back of the question.

Answer the total time control within two hours, appropriate rest adjustment.

Allow at least half an hour to apply the answer card.

2, examining

Look at the options first, then look at the problem, find the information about the options, and remove the interference information. Vary

Look at the beginning and end of the problem, the beginning will tell you important information, the end will explain what you want to test you.

Notice the last word "except".

3. Decision-making

Don't spend too much time on completely unfamiliar options.

If you can analyze the stage of the examination questions or knowledge areas, first exclude irrelevant options.

When you do the problem, the teacher will explain the content and the content of the textbook, and then combine your thinking to make the answer.

The answer to the question refers to the relative correctness of the option, not the absolute degree of correctness.

Don't add conditions to the topic yourself.

4. Methods and techniques of answering questions

All levels of the morning module exams are choice questions, which require candidates to choose from four alternative answers to a correct answer, corresponding to such questions, often using direct push method and screening method.

(1) Direct Push method : First do not analyze the difference between the four answers and contact, according to the content to direct the correct answer, and then choose from four answers to the most appropriate answer.

Example 1: When you configure management, you typically build different configuration databases depending on your needs. Usually () is used to store a stage product that is released at the end of a phase of work.

A. Development Library B. Baseline Library C. Controlled library D. Product Library

Analysis: The knowledge point involved in the subject is "computer system development and operation and Configuration", mainly examines the configuration management in the configuration database type. To achieve change management, one of the most important means is to establish a configuration database, depending on the purpose, the configuration database can be divided into the following three categories:

Development Library: For developers to use, can be modified frequently.

Managed Library: A stage product that is released at the end of a period of work. As the name implies, controlled, that is, can not be arbitrarily changed.

Product Library: finished the software after the system test.

So we can directly draw the correct answer: C.

(2) screening method : The four answers given will be analyzed, compared, quweicunzhen, step-by-step screening and elimination, and finally establish a correct answer.

Example 2: A computer system consists of the components shown, assuming that each part of the thousands of hours of reliability R is 0.9, then the system's thousand-hour reliability is about ().

650) this.width=650; "src=" Http://s2.sinaimg.cn/mw690/002c1tKNgy71KNYU7mh61 "title=" "style=" border:0px; Vertical-align:middle; "/>

a.0.882 b.0.951 c.0.9 d.0.99

Analysis: This topic examines the knowledge of system reliability calculation. In fact, we just need to figure out some answers, the last thing left is the correct answer, that is, save time, reduce the probability of error in calculation. In the question, r=0.9, we look closely at the diagram, to arrive at a conclusion: even if the following two parallel modules are not error (reliability is 1, basic impossibility), the entire system R upper limit can only be: 0.9x1x1=0.9. The above mentioned hypothetical situation is basically impossible, so the whole system reliability must be less than 0.9, the answer to meet the condition is only 0.882, so the correct answer is: A.

Of course, there is a way to have a certain strength, so as to be in an invincible position in the choice question. The choice question examines the knowledge point to be broad and thin, the examinee needs to have certain concept resolution ability. This requires candidates in the usual review of more analysis and comparison, summary. The number of choice questions in the exam, scores scattered, candidates should have a global concept, to ensure that most of the topics of the score, encounter will not be the topic can be temporarily first slightly past, and so on, the topic is more, the knowledge of the outline opened, the previous questions involved in the knowledge structure may reappear, at this time to return to the previous problem,
