Consider a system which uses a ring-based access control mechanism with 9 rings (from 0 to 8). Consider two procedures running in this system p1 and p2. Procedure p1 is executing and needs to invoke procedure p2. Procedure p2’s bracket is (3,5,6). Procedure p2’s ACL gives p1 full (read, write, append, and execute) rights to p2. In which ring(s) must p1 execute for the following to happen? p1 can invoke p2, but a ring-crossing fault occurs p1 can invoke p2 provided that a valid gate is used as an entry point p1 cannot invoke p2 p1 can invoke p2 without any ring-crossing fault occurring, but not necessary through a valid gate.

Given int variables k and total that have already been declared, use a while loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. thus your code should put 11 + 22 + 33 + + 4949 + 50*50 into total. use no variables other than k and total.

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?
