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?
Given the following pseudocode:
Program tax check
Integer: tax_rate
real: tax%
BEGIN
tax% := 0
GET (tax_rate)
WHILE tax_rate > 0 loop
IF tax_rate > 3 THEN
tax_rate := 3
ENDIF
tax% := tax% + (tax_rate / 10)
tax_rate := tax_rate - 1
ENDLOOP
IF tax% > 0.6 THEN
print ("tax rate is high")
ELSEIF tax% < 0.1 THEN
print ("tax rate is zero")
ELSE
print ("tax rate is low")
ENDIF
END tax check
