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. Caching
• C. Connection pooling
• D. Distributed processing

You are a Technical Test Analyst preparing load test scripts. You have been invited to a technical review of the system's operational profile document produced by the business. The meeting is next week, during your preparation you notice that volumetric data covering projected transaction volumes will be held in a separate document that will not be available before the meeting. What would be the BEST course of action?

• A. Request that the meeting be delayed until the volumetric document has been drafted and examined by the reviewers
• B. State that you are not a mandatory reviewer but request that both documents be sent to you once agreed
• C. To avoid delay to the project, attend the review as scheduled and raise the issue at the meeting
• D. Delay the review but limit schedule impact by presenting the volumetric document to the reviewers during the meeting

You have run static analysis tools against four large, complex code components (A, B, C, and D) with the following measures reported:
(Insert Table 1)
You must decide which component should be selected FIRST for applying maintainability improvements. The combination of Cohesion and Coupling is regarded as the MOST important factor, v/ith the number of repeated code sections as the next important factor.
Which component should you select?

• A. Component B
• B. Component C
• C. Component D
• D. Component A

You are working on the first release or an online dating service product Market research has shown that the site can expect to experience its heaviest usage during the months of January March June October. November and December During these months usage can be 2 to 10 times higher than dunng other times it has also been determined that people win not tolerate a wait time higher than 2 seconds for queries made regarding potential dates who have selected their profile Extensive usability studies have been done by the marketing department, including work with focus groups and comparative analysis of other similar sites The analysis on the project have provided detailed Ul mockups in reading the design documents, you have discovered that the marketing team plans to run reports to analyze usage patterns to improve the advertising What item on the architecture review checklist will be important to verify to ensure these reports don't impact the user response time?

• A. Load balancing
• B. Lazy Instantiation
• C. Connection pooling
• D. Process isolation between OLTP and OLAP
