The last release of a hotel booking website resulted in poor system performance when hotel searches reached peak volumes. To address these problems in the forthcoming release, changes to the system architecture are to be implemented as follows:
Change 1 - Provision of a single Internet service using multiple servers, rather than a single server, to maximize throughput and minimize response time during peak volumes Change 2 - Prevention of unnecessary database calls for objects that were not immediately needed by the calling applications. Achieved by not automatically creating database connections at the start of processing, instead only just before the data is required.
The system architecture document has been drafted and as Technical Test Analyst you have been invited to participate in its review. Which of the following review checklist items is MOST likely to identify any defects in the proposed system architecture for Change 1?

• A. Load balancing
• B. Connection pooling
• C. Distributed processing
• D. Caching

Which TWO of the following could be identified using Dynamic Analysis?
A) Objects having too much or too little visibility into parent classes.
B) Repetition of code within a single component or module.
C) System memory not released when it is no longer needed.
D) Pointers in a program that are no longer accurate and must not be used. E. Code that cannot be reached and so will not be executed.

• A. d and e
• B. a and c
• C. a and b
• D. c and d

BestFor Incorporated is a rapidly growing online financial services company that offers guidance to its customers on a range of financial products. Its first website, BestForMortgages, was launched two years ago, shortly followed by BestForPensions. The popularity of both sites has driven the company to expand its offerings into other sectors and a third website, BestForFood, is currently under development.
The first two websites have proven to be functionally robust but suffered from performance issues due to:
Underestimation of concurrent user access at peak times in its original operational profiles Data volumes rapidly growing beyond expectations on a single database shared by both sites.
All three websites will share the same web server.
In consideration of the problems encountered with the first two websites, which TWO of the following types of testing should be performed on the BestForFood website to see whether similar defects exist?
A) Load Testing
B) Stress Testing
C) Scalability testing
D) Portability Testing
E) Recoverability testing

• A. d and e
• B. a and c
• C. b and c
• D. b and d
