One of your work tasks is to inventory all the software running on the network. You’ve been running Wireshark on your network for several weeks now. You’ve built a long list of all the source and destination port numbers seen on your network. As you examine this list, you find that there are more than 100 port numbers that are not listed on the IANA port list. There are also about 20 port numbers that belong to applications you know are not running on your network. What happened? Why are your research results so far off base?

A local area network (LAN) makes use of something called a hub. Is there a route out of the collision zone that we don't have to go into? In the event that this is the case, could you kindly elaborate? In the event that this is not possible, what alternative types of technology are available, and how do they function?

You’re the database administrator for a large grocery store chain. When you leave on Wednesday, there are no problems. When you arrive on Thursday (the day a new sale starts), you learn that the network is down. It went down before the local stores could download the new sales prices. All scanned goods will ring up at the price they were last week (either sale or regular) and not at current prices. The provider says he is working on the network problem but can’t estimate how long the repairs will take. How do you approach the problem?

Imagine for a moment that the desktop of your computer is completely covered with FIN WAIT 1 TCP connections, and that you have a large number of these connections. Is there a certain outcome that is more likely to take place than the others? Who precisely is to blame for this situation?

the question i am having trouble with is: you are designing an application at work that transmits data records to another building within the same city. The data records are 500 bytes in length, and your application will send one record every 0.5 seconds. is it more efficient to use a synchronous connection or an asynchronous connection? What speed transmission line is necessary to support either type of connection? juat looking for some insight on how to solve for the connection and also for the speed.

Three students, including A, B, and C, share the same apartment. They have been assigned with 3 IP addresses, respectively. However, there is only one Ethernet cable outlet in the apartment. Therefore, they decided to buy a device to connect three computers to the outlet. Suppose none of them can use port mirroring if the device is a switch, please identify all statements that are true below.    Question 11 options:   If the device is a hub, A can sniff B's and C's packets since the hub will broadcast all packets to all ports.    If the device is a switch, A cannot sniff B's and C's packets without launching any attack.   If the device is a switch, A can sniff B's and C's packets if A can launch ARP spoofing attacks against B and C successfully.    None of above is correct.

When using HTTP streaming, are the TCP receive buffer and the client's application buffer the same thing as each other? If they don't communicate with one another, how do they interact with one another?

Write down the commands to configure each step Assuming SW1 is a 24 port switch. Connect PC1, PC2, PC3, PC4 and PC5 on port numbers 6, 8, 13, 17 and 21 respectively. Configure VLANs on SW1 in such a way that PC1 should ping PC2 only and PC3 should ping PC5 only. PC4 should not be able to communicate with any other PC (Note: All ports on SW1 connecting to other switches will be kept in default VLAN) Configure Ether-channel between SW2 and SW6. Show commands.
