When parallelizing an application, the ideal speedup is speeding up by the number of processors. this is limited by two things: percentage of the application that can be parallelized and the cost of communication. amdahl’s law takes into account the former but not the latter. a. [10] < 1.10> what is the speedup with n processors if 80% of the application is parallelizable, ignoring the cost of communication? b. [20] < 1.10> what is the speedup with 8 processors if, for every processor added, the communication overhead is 0.5% of the original execution time. c. [20] < 1.10> what is the speedup with 8 processors if, for every time the number of processors is doubled, the communication overhead is increased by 0.5% of the original execution time?

You have been supporting csm tech publishing's windows server 2016 server network for over a year. the office has two windows server 2016 servers running active directory and a number of other roles. management has informed you that a small sales office is opening in the same building three floors up. the sales manager wants to install a sales application on a server located in the sales office. this server will have limited physical security because there's no special room dedicated for it, which means it will be accessible to non-it personnel and visitors. you're considering installing windows server 2016 server core on the new server because accessing its console regularly probably won't be necessary, and this server will be managed from one of the other csm tech publishing servers. what are the benefits and drawbacks of using server core for this branch office? what are some things you should do to set up this server management environment?
