Is it possible for two network interfaces to share a single MAC address? What might possibly be the cause of this? Can two network interfaces share the same IP address? Do you have any ideas as to why this would be the case?
How can you troubleshoot issues related to DNS cache poisoning attacks that disrupt domain name resolution in a network?
Please answer and not copy answers from the internet cause i need some understading :
An educational institution has an access network whose operating parameters are as follows:access link to originating servers’ rate: 15.4 MbpsRTT from institutional router to server: 2 secWeb object size: 100K bitsAverage request rate from browsers to origin servers: 150/sec average data rate to browsers: 45.0 MbpsInstitutional access network speed: 1Gbps.
3.1. You are requested to provide the performance of the institutional access network in terms of• LAN utilization• Access link utilization• End-to-end delay from the access network to the origin servers.
Note: Assume that the requests from the web client to the originating web servers are of the order of 2GB of data on average.
3.2. Assuming that the institution would like to install a web cache in its access network with a cache hit rate is 0.65, you are asked to recompute the new performance of the access network…
