False
2. An architecture that can be used to create a solution for a problem (“a good solution”) must: (1 point each):
a. Be the absolute best architecture for that system?
True
False
b. Support the implementation of all the functional requirements for the work that has to be done;
True
False
c. Help the implementation of the system achieve a value for all quality requirement that is greater than or equal to all qualities that have a minimum acceptable value;
True
False
d. Help the implementation help the system achieve a value for all quality requirement that is less than or equal to all qualities that have a maximum acceptable value.
True
False
e. Must be buildable within any cost, budget, and schedule constraints by the available personnel. (Note some engineers/architects include these as qualities of the system).
True
False
3. The “best” architecture(s) is an architecture that is in the set of known good architectures, that give the best blend values for the qualities once arranged in order of importance to the stakeholders? (Note: the stakeholders may not agree on an absolute order, in which case there can be more that 1 “best”) (1 point):
True
False
4. What pattern is represented by the following diagram? (1 point)

a. Service Oriented Architecture
b. Publisher-Subscriber
c. Control-Loop
d. Blackboard
e. Broadcast
5. Your chief architect has concluded that the Central Monitor Subsystem is likely to be too slow for the system to achieve an acceptable level for Latency (measured from the time a door or window is opened until the police are called. So, he had decided that:
a. There should be separate subsystems: (i) Monitoring Subsystem, and (ii) Customer Management subsystem;
b. The Monitor Subsystem should have
i. A Controller and Database Management System (DBMS) for handling the alarm messages from the home;
ii. The Controller should automatically process all alarm messages, including the check with the customer whether the brake-in is real, calling the police, and tracking progress, which it saves to its DBMS;
iii. One operator station should be dedicated to monitoring the activity of the Controller;
iv. A new component that should synchronizes the Home Owner-Customer and Event History databases in the Monitoring DBMS with the corresponding databases in the Customer Management DBMS when time permits
c. The Customer Management Subsystem should have the remaining Operator Stations, Server(s) and DBMS.
You have been tasked to update you Internal Block Diagrams for the Central Monitoring Subsystem to reflect this structural change. (6 points)
