SELECT ONE OPTION

• A.RTE.
• B.LDAP.
• C.MMS.
• D.WSCL.

ich ONE of the following options is a specific performance risk in mobile applications?
ONE OPTION

• A.Slow data flow from sensors.
• B.Network congestion.
• C.Inefficient Implementation of algorithms.
• D.Limited resources.

(REFER TO BASE SCENARIO 2): When you refer to Base Scenario 2, you are referring to the description and only the description, without any modification.
Question specific constraints: (specific constraints are not part of the Base Scenario and are specific to this question).
Throughout the month of January (31 days), the company performed 3,100 departure operations from the Capital City Airport. These departure operations transported 465,000 passengers during the hours of operation, from 07:00 to 23:00.
The departing passengers (one of the most relevant operational profiles) will access the front-end of the application to check in for their flight. It is known that 30% of departing passengers reconnect after checking in to request the boarding pass to be resent or printed.
Question
Assuming there is one boarding every 5 minutes, what should be the minimum front-end processing capacity of the system for the "departing passenger* user? It is assumed that there will be 12 peaks or maximums per hour.
SELECT ONE OPTION

• A.100 * 12 + (60 -12) * 10.42 = 1.700.16 transactions/hour
• B.100 * 12 + (60-12) *4.69 = 1,425.12 transactlons/hour
• C.100 * 12 + (60 -12) * 15.10 = 1,924.80 transactions/hour
• D.100 * 12 + (60 -12) * (10.42 - 4.69) = 1.475.04 transactions/hour

Base Scenario 2 : This Base Scenario 2 is used for 8 questions throughout this exam. When you refer to Base Scenario 2, you are referring to this description and only this description, without any modification.
Natalie works for a company that develops an online check-in management software for a major international airline.
Online check-in is available for passenger check-in from 24 to 1 hour before boarding time.
Once the registration is confirmed by the customer and the system, the information must be available to the rest of the types of users (flight managers, among others) in a maximum time of 3 seconds (it is expected that this temporal constraint is met in 90% of the transactions and that 90% of the transactions are completed at 100%).
At the beginning of the check-in window, there are peaks of 100 users per minute, for one minute.
Question
Which of the following options is a performance-related business objective that could be suitable for this project?
SELECT ONE OPTION

• A.The system must be capable of supporting peak concurrent users in excess of 6,000 users per hour for one minute, accessing check-in without performance degradation, considering that peaks must not exceed a value that exceeds the processing capacity of the system.
• B.The system must be able to support peak attendance of 1,000 users, considering that there cannot be more than two flights with overlapping schedules.
• C.The system must be able to support 200 concurrent users with a response time of one second for the issuance of the boarding pass, considering that the fleet is likely to have a very high percentage of medium size aircraft.
• D.The system must have a completion time of up to three seconds for 2,000 concurrent users for updating passenger check-in data

Choose the option that BEST describes valid opportunities for the dynamic performance testing.
SELECT ONE OPTION

• A.During unit testing, including using or not profiling information to determine potential bottlenecks and white box techniques to evaluate resource utilization.
• B.During acceptance testing, especially for data flows and workflows across key inter-system interfaces. In system integration testing, it is not uncommon for the "user* to be another system or machine (e.g. inputs from sensor inputs and other systems).
• C.During component Integration testing, across any kind of use cases and workflows, especially when integrating different use case features or Integrating with the "backbone" structure of a workflow.
• D.During system testing of overall end-to-end behaviors under various load conditions.
