%. Therefore, our workshop will introduce you to the RHCE Lab Test process and skills, hoping to help you obtain your own RHCE certificate. RHCE is somewhat different from other MCSE and CCNA certificates because it not only tests the examinee's familiarity with RedHat Linux using multiple choice questions, but also requires a one-day internship, this includes the RedHat Linux installation settings and the Troubleshooting section. The method for apply

today will bring you a new technical introduction series, the name of this series is called "Routing technology in the enterprise's specific application" This is the first article series, "Static routing, default route NAT and static floating routing "I think when you see these nouns, you will not be unfamiliar, whether you are learning Cisco Certification system ( Ccna-ccie) , or to learn the Huawei Certification system (Hcna-hcie) friends may be in

, wireless, voice, data center and so on many aspects, so there are a lot of content need to learn and understand, but lofty high-rise flat, so the basis for the system operation and maintenance is the most important, for the network learning should start from the foundation, network knowledge of the beginning.Network Basic Learning SystemCisco Course System Overview (CCNA), although the knowledge content is not too much, the training cycle generally

wireless is basically from the terminal to a device transmission between the wireless technology, the ultimate backbone or cable or fiber media transmission.So routing switching is the basis of the foundation. This course will build the values of your entire IP network system, so it is recommended to start your network from this course. In-group recommendations: Routing switch learning, you can go to the wireless course, a lot of public CCNA

And the n

router receives a route from OSPF and a route from RIP, it chooses the OSPF route. Because the management spacing of OSPF is 110, the management spacing of RIP is 120. Here's another example: your router receives a route from EIGRP internal, and its management spacing is 90, but you accidentally enter a static route into an IP address where the spacing management address is 1. Then the router uses a static route and does not use EIGRP routing. (☆ Introduction to Programming Network ☆) Finally

formula combines the old RTT (R) and the new RTT (m) to consider the size of the new RTT (R. However, we can see that this kind of estimation is completely unable to make a "sensitive response" when the network is greatly changed (not even mentioned by Jacob boson ), the following formula is provided: Err = M-A A D RTO = a + 4D For specific explanations, please read the 228 page.

, you can also abstract it into three use cases based on the specific operations in the case. The system requirements expressed by it are exactly the same as those of a single use case model. How should we determine the granularity of use cases? At a technical seminar, someone asked Dr. Ivar Jacob boson how many use cases are required for a system? The answer from the master is 20. Of course, he means that it is better to control the scale of the cas

Whether it is to maintain the security of your balance treasure encryption process or you play "Battlefield 4", the computer will produce random numbers. There are two kinds of random numbers--"true" random numbers and pseudo random numbers--the difference of which is related to the security of the encryption system. As the discussion of random numbers heats up, many people suspect that random-number-generation chips built into various hardware within Intel are reliable. To understa

For the optimization of the site, successful keyword analysis will help the site do half the work, the remaining half is the implementation of details and link optimization, because the grasp of the key words determines the direction of our work, the direction is correct, in order to achieve the goal we want to achieve faster. I do not know if you have seen boson analysis of the expression of the keyword, of which the k

This video is the first video course of some network-related training courses for Linux System Engineers. The main content is the IP routing principle and the RIP Protocol. At work, I found that many Linux O M personnel encounter bottlenecks due to lack of basic network knowledge, and it is still a common phenomenon thanks to the inapplicable education system in China ). From the perspective of public welfare and personal knowledge sharing, I plan to share a series of online knowledge. The re

selects an OSPF route. Because the OSPF management interval is 110, and the RIP management interval is 120. Here is another example: for example, if your vro receives a route from Internal, its management interval is 90, But you accidentally input a static route to an IP address, the Gap Management address of this IP address is 1. The vroeigrp uses a static route instead of an IPsec route. The last point is to emphasize that the management interval is the focus of the
