Two rounds of testing preceded the release of the cheque-return module. In the rst, the module was exercised at the bank's own development centre by a team drawn from the systems department and the methods cell, working from scripted cases, with the developers present in the room to observe the failures and correct them as they arose. In the second, the module was placed at eleven branches and used upon live work by the branch sta , with no developer present and no script; the branches recorded whatever went wrong and reported it back at the end of each week. The two rounds are, respectively:

1. ABeta testing and alpha testing
2. BAlpha testing and beta testingCorrect
3. CSystem testing and integration testing
4. DSmoke testing and regression testing
5. EWhite-box testing and black-box testing Directions (Q19–Q49) : Questions 19 to 49 concern the information systems of Chandrabhaga Urban Bank, whose technology committee has this year taken up together the network that joins its branches, the databases that hold its records, the packaged and in-house software it runs, the manner in which that software is procured and built, and the measures by which its terminals and its handheld devices are secured. The seven-layer reference model reproduced in Figure 1 and the analyst's picture of the chequereturn module reproduced in Figure 2 are to be looked at whenever a question below points to either of them. Against every question below stand ve responses lettered (A) to (E). Exactly one of them disposes of the question as it has been framed; mark that one and no other. Layer 7 Layer 6 Layer 5 Layer 4 Layer 3 Layer 2 Layer 1 Application – the interface offered to the user process itself Presentation – the form in which the data is represented on the wire Session – the dialogue between the two end processes Transport – end-to-end delivery between processes Network – delivery of the packet from source host to destination host Data link – delivery of the frame across a single link Physical – the bit stream upon the medium EXTERNAL ENTITY – the clearing house, which hands in the return memo for every dishonoured instrument ▼ PROCESS 1 – validate the return memo against the presentation register and reject any memo that names no known instrument ▼ DATA STORE D1 – the presentation register, read by process 1 and written by process 2 ▼ PROCESS 2 – raise the return charge upon the drawer's account and post the reversal entry ▼ EXTERNAL ENTITY – the branch, which receives the return advice and the charge intimation
