Network Engineer Exam Satisfaction 100 points do what it says

I'm a communications major.

Network Engineer"It belongs to the category of national soft examination.

Three levels in the direction of the network"Network Engineer"It belongs to the intermediate level, and the elementary one is called"Network administrators"

Generally so-called"Cross the line"There are national and provincial lines.

Crossing the national line of the intermediate"Network Engineer"It's almost the level of a university lecturer.

I have read the relevant tutorials and past exam questions, and the exam questions can not only have breadth but also depth. The difficulty is relatively large.

Have relevant professional knowledge, intellectual property patent law, English test questions.

Judging from the ability of college students, it is quite good to be able to take the intermediate certificate.

2.About employment.

Network Engineer Because it is really difficult, basically social recognition is okay. Contrast to"Computer-based exams"More professional strength. Of course, if the employment environment is particularly bad, (like this year's financial crisis) it is difficult to find any certificates, but some are better than nothing.

3.Graduate school entrance examination. Now the postgraduate examination for computer science majors has also implemented a unified examination, and you can buy the syllabus to correspond to the systematic review. In fact, it is also very common to go to graduate school across majors, but you have to put in more effort.

In addition, network engineers and computer science graduate school have nothing to do with each other.

Network Engineer is a certification at the relevant level;

The computer science entrance examination is an exam that you need to go through for graduate school.

Moreover, network engineering and computer science do not focus on the same direction of expertise.

I'm already past my third year of online engineering, and now I'm going to take the computer science graduate exam, and I feel that the recognition of network engineering is in general, and if there is any problem, we will communicate with each other.

I am a computer science major, and I am preparing for the network engineer exam, and now I have a network engineer certificate to go out to find a job, which is not very easy to find, and only belongs to the intermediate level. The network engineer exam does not test English and other subjects, but only the computer aspect, which has a wide range, and there are English questions in the test questions. I don't know the difference between a computer engineer and a network engineer 、、、

Network Engineer Interview Question 1: How does a switch get packets?

The switch learns the source MAC address in the dataframe.

Generally the simplest protocol concept, there are also some commonly used protocol port numbers such as EIGRP what protocol is, what is its port number, what does it do, and will not let you touch the device,

Analysis] Using Shannon's theorem c=wlog2(1+s n), and because db=10log10(s n), so c=40kbps, and back to Nyquist's law, if r=2wlog2(n), calculate n=32.

A software engineer generally refers to a person who pursues a career in software development. The difference between a software engineer and a general programmer is that a programmer's job is to code according to specified specifications, while a software engineer's job requires design and planning. However, as the division of labor in society is becoming more and more blurred, the division of labor between software engineers and programmers is becoming less obvious.

However, for organizations that strictly enforce CMM, the division of work between each person is clearer, which helps to understand the difference between software engineers and general programmers.

First question:

A4000H and CBFFFFH are both hexadecimal data, H represents hexadecimal, so the number of bytes from A4000H to CBFFFH is: CBFFFH(835583)-A4000H(671744)+1=28000H(163840), the mantissa H in some equations represents the hexadecimal number, and the number in parentheses is its corresponding decimal number, so there are 163840 bytes in them, And 163840 1024=160, so that there are 160*1024 bytes in A4000H to CBFFFH.

The second question: If a memory chip with a storage capacity of 32k*8bit is used to compose the memory, then 5 chips are required.

Department A, Department B

Department C, Department D

2) If you want to draw a diagram, you don't need to draw it, the idea is to divide VLANs, and then use Layer 3 switches or routers to communicate with each other between different VLANs. Hope it helps.

Roughly speaking, it is the person who works on computer structure construction, hardware maintenance, ** construction, and multiple cross-regional networking, but it is not complete, these are some of them.

a=10b=11

c=12d=13

e=14f=15

cc000h-a4000h=28000h

h stands for hexadecimal.

28000h=2^17+2^15=128k+32k=160k28000h=0010

binary) = 2 17 + 2 15

From 1k=2 10, we can let the rock deduce the following result:

2^17=2^10×2^7=1k×128

2^15=1k×32=32k

128k+32k=160k
