Failures_and_Recovery_3 LRVM Give one pro and one con for the “no_flush” mode in end_transaction.

Failures_and_Recovery_7 Quicksilver In Quicksilver, assume the following:  There is a file server, which talks to a directory server for mapping a client’s file name to an index node that contains the disk block addresses for the file;   The directory server talks to a data server that manages the allocation of disk blocks to store the file contents.  A client opens a file and starts writing to it. The directory server crashes in the middle of the file write by the client. Mention any two possible inconsistent states that may result by identifying the breadcrumbs that may have been left behind due to this crash.

Real_time_and_Multimedia_3 PTS Your friend is a geologist who studies earthquakes and tsunamis. They have placed 1000 seismograph sensors all around the world. Each sensor produces a 1 kilobyte datapoint every second. They have also placed 50 cameras in coastal areas around the world that record at 60 frames per second. Each video frame is 1 MB.  Your friend wants to record this data and analyze it for two purposes:  To send urgent alerts when multiple sensors in a region report strong shaking in the same brief time window. To correlate timestamped video recordings with timestamped seismograph data in order to study what types of shaking cause tsunamis. Is PTS a good basis to build a system for analyzing this data? Justify your answer. 

Failures_and_Recovery_6c Quicksilver The context for this question is same as previous. You are designing a distributed database system on top of the Quicksilver operating system. The system allows clients to perform “read” and “write” operations on data stored across multiple nodes. Each operation generates a transaction tree for recovery purposes. For persistent changes made during a “write” operation, what cleanup protocol would be appropriate? Why?

Firm value always increases as more debt is addedII. Firm value stays constant as more debt is addedIII. WACC always decreases as more debt is addedIV. WACC always increases as more debt is addedV. WACC stays constant as more debt is added

Defects of the IRR method versus the NPV is that the IRR does not consider: I.     Cash flows after the payback periodII.     The time value of moneyIII.     Differences in the size of projectsIV.     Unconventional cash flows (i.e., outflow, inflow, then another outflow) 

The Francis Company is expected to pay a dividend of D1 = $1.25 per share at the end of the year, and that dividend is expected to grow at a constant rate of 6.00% per year in the future. The company’s beta is 1.15, the market risk premium is 5.50%, and the risk-free rate is 4.00%.  What is the company’s current stock price?

Langston Labs has an overall (composite) WACC of 10%, which reflects the cost of capital for its average asset. Its assets vary widely in risk, and Langston evaluates low-risk projects with a WACC of 8%, average-risk projects at 10%, and high-risk projects at 12%.  The company is considering the following projects:                                  Project                           Risk                   Expected Return                                    A                               High                            15%                                    B                            Average                         12%                                    C                               High                            11%                                    D                               Low                              9%                                    E                               Low                              6%   Which set of projects would maximize shareholder wealth?

22.    Which of the following statements is CORRECT? I. One advantage of dividends over share repurchases is that dividends provide financial managers with more flexibility.II. Despite several advantages of share repurchases, dividends remain the dominant form of shareholder payout.III. After announcing a share repurchase program, a firm is not required to repurchase any of the shares it intended to buy back.

Which of the following statements is CORRECT? (Assume that the projects being considered have conventional cash flows, with one outflow followed by a series of inflows.)
