Everyday Ten Ask ccie 400-101 study guide pdf

1. Question: Is the switch docking virtual machine unreachable?

Answer: The data sent by the VM cluster may be a vlan tag. The interface of the switch is configured with a trunk and the corresponding vlan is created.
2. Question: Under the interface, is sw mode trunk  reported incorrectly?
Answer: (1) Check if there are any configurations on the port
(2) Determine the role of the port
3. Question: The physical interface has been configured as the mirroring destination port. Can you also add this physical interface to the member ports of the aggregation port?
Answer: Configuration is not supported. A physical port is configured as a mirroring destination port. It is not supported to add the physical port to an aggregation group.
4. Question: What is the difference between dynamic and static aggregation applications?
Answer: Dynamic aggregation can dynamically discover link failure, avoid static aggregation, single line is not accessible (e.g. although switch side up, due to intermediate fiber problems can no longer communicate the situation), the user has high reliability requirements that member ports dynamically join to leave switching speed requirements are faster when the use of dynamic aggregation is recommended.
5. Question: What is the type of message format for the lacp dynamic protocol to send lacpdu, and what is the address for which the purpose of the message is sent?
Answer: LACPDU message when a two-tier Ethernet message, its characteristics are as follows:
(1) EtherType is 0x8809.
(2) The purpose is fixed at 01:80:c2:00:00:02 multicast address.
(3) The content of the message is divided into two parts with the same structure, Actor (this end) and Partner (the peer saved by this end)
6. Question: The switch uses static port aggregation. What is the default load balancing?
Answer: Load balancing based on source and destination mac.
7. Question: What standard protocol is port aggregation?
Answer: The standard protocol used for port aggregation is 802.3ad
8. Question: The switch made a port aggregation computer, the computer can use normally?
Answer: The dynamic aggregation computer of the switch configuration can not be used normally because the static aggregation does not need to be negotiated, the configuration is effective. Then, the static aggregation configuration can be used normally when the terminal.
9. Question: When both the switch and the switch's ports are configured with spanning-tree portfast, is that causing the straight connection to fail?
Answer: You can either directly default interface gi0/X or when you turn off the spanning tree removal configuration.
10. Question: How does the switch see which interfaces participate in STP computing?
Answer: View using the command show span summary which shows the ports under the command that participate in the stp calculation.

I believe many people have the experience of being cheated. lowest The means of defrauding money is: Your good friend comes to borrow money from you, and you have a relationship card with you so that you can lend him money. At this time, according to the normal person’s thinking, this friend has known me for many years that he might not take the money away. Note that it is often the same idea that gives others the opportunity to owe money. If the amount borrowed is not high, then it is okay.

What is proxy communication?

Is it correct to understand the working level of forward proxy reverse proxy transparent proxy? Forward proxy and reverse proxy (application load balancing, some NG reverse proxy) can be understood as a man-in-the-middle mode. At the same time, both ends establish a TCP connection, and then the man-in-the-middle performs TCP connection between the two ends. Can a transparent proxy be understood as a simple and crude "hijacking" of a passing data packet, without splitting the complete TCP connection into two independent segments. So, in this sense, this kind of transparent proxy is similar to the working hierarchy of NAT devices? Preface I once saw a person write tens of thousands of words to answer a question, and read it after three days. Shocked, what is all this for? These words can produce a book, and it is also a reward for your hard work. However, I think the man has always been happy, but there is no doubt that his reputation (Reputation) is in full swin
