Suppose that a bank wishes to make a 5% rate of return on a one-year loan but expects inflation over the course of the loan to be roughly 3% (and assuming not risk of default).

Which statement is TRUE?

a. If the bank charges an interest rate of 8% or higher, it will earn the expected return.

b. As long as the bank charges a nominal interest rate of at least 5%, it will earn its expected return.

c. If the bank charges 8% and the inflation rate is less than 3%, then the bank will have earned a higher rate of return than expected.

d. If the bank charges 8% and the inflation rate is more than 3%, then the bank will have earned a higher rate of return than expected.

Problem 3: access control pokeygram, a cutting-edge new email start-up, is setting up building access for its employees. there are two types of employees: managers and engineers, and there are three departments: security, networking, and human resoures. each employee works in a single department, and each department is housed on a different floor. managers are allowed access to any floor, while engineers are allowed access only to their own floor. there are three badge-operated elevators, each going up to only one distinct floor. every employee has one badge. pokeygram wants to use the best possible access control method in order to minimize delay for the elevators (a) access control matrix, 1. which of the following would you recommend that pokeygram use: (b) access control lists, or (c) capabilities? make sure to justify your answer. 2. what, if any, would be the benefits (and/or disadvantages) of using rbac (role-based access control) in this situation? keep your solution for this problem limited to 10-12 lines of text.
