43. A server crashes on the average once in 30 days, that is, the Mean Time Between Failures (MTBF) is 30 days. When this happens, it takes 12 hours to reboot it, that is, the Mean Time to Repair (MTTR) is 12 hours. The availability of server with these reliability data values is approximately :

  • Option : C
  • Explanation :
    MTBF = 30 days = 30 * 24 = 720 hour. MTTR = 12 hour. Availability(A) = MTBF / (MTBF + MTTR) i.e. A = 720 / (720 + 12) = 0.9836 = 98.36%. So, option (C) is correct.

44. Match the software maintenance activities in List – I to its meaning in List – II.

List - IList - II
I. Corrective (a) Concerned with performing activities to reduce the softwarecomplexity thereby improving program understandability and increasing software maintainability.
II. Adaptive (b) Concerned with fixing errors that are observed when the software is in use.
III. Perfective  (c) Concerned with the change in the software that takes place to make the software  adaptable to new environment (bothhardware and software).
IV. Preventived) Concerned with the change in the software that takes place to make the software  adaptable to changing user requirements.

Codes:

 IIIIIIIV
(1)(b)(d)(c)(a)
(2)(b)(c)(d)(a)
(3)(c)(b)(d)(a)
(4)(a)(d)(b)(c)

  • Option : B
  • Explanation :
  • Corrective Concerned with fixing errors that are observed when the software is in use.
  • Concerned with the change in the software that takes place to make the software adaptable to new environment (bothhardware and software).
  • Perfective Concerned with the change in the software that takes place to make the software adaptable to changing user requirements.
  • Preventive Concerned with performing activities to reduce the software complexity thereby improving program understandability and increasing software maintainability.
  • So, option (B) is correct.

45. Match each application/software design concept in List – I to its definition in List – II.

List – I   List – II
I. Coupling (a) Easy to visually inspect the design of the software and understand its purpose.
II. Cohesion(b) Easy to add functionality to a software without having to redesign it.
III. Scalable   (c) Focus of a code upon a single goal.
IV. Readable   (d) Reliance of a code module upon other code modules.

Codes:

 IIIIIIIV
(1)(b)(a)(d)(c)
(2)(c)(d)(a)(b)
(3)(d)(c)(b)(a)
(4)(d)(a)(c)(b)

  • Option : C
  • Explanation :
  • Coupling is reliance of a code module upon other code modules.
  • Cohesion is easy to visually inspect the design of the software and understand its purpose.
  • Scalable is focus of a code upon a single goal.
  • Readable is easy to add functionality to a software without having to redesign it.
  • So, option (C) is correct.
