SCEA Objectives
Section 1: Concepts
-
Draw UML Diagrams
-
Interpret UML diagrams.
-
State the effect of encapsulation, inheritance, and use of interfaces on
architectural characteristics.
Section 2: Common Architectures
-
Recognize the effect on each of the following characteristics of two tier,
three tier and multi-tier architectures: scalability maintainability,
reliability, availability, extensibility, performance, manageability, and
security.
-
Recognize the effect of each of the following characteristics on J2EE
technology: scalability maintainability, reliability, availability,
extensibility, performance, manageability, and security.
-
Given an architecture described in terms of network layout, list benefits
and potential weaknesses associated with it.
Section 3: Legacy Connectivity
-
Distinguish appropriate from inappropriate techniques for providing access
to a legacy system from Java code given an outline description of that
legacy system
Section 4: Enterprise JavaBeans Technology
-
List the required classes/interfaces that must be provided for an EJB
technology.
-
Distinguish stateful and stateless Session beans.
-
Distinguish Session and Entity beans.
-
Recognize appropriate uses for Entity, Stateful Session, and Stateless
Session beans.
-
State benefits and costs of Container Managed Persistence.
-
State the transactional behavior in a given scenario for an enterprise bean
method with a specified transactional deployment descriptor.
-
Given a requirement specification detailing security and flexibility needs,
identify architectures that would fulfill those requirements.
-
Identify costs and benefits of using an intermediate data-access object
between an entity bean and the data resource.
Section 5: Enterprise JavaBeans Container Model
-
State the benefits of bean pooling in an EJB container.
-
State the benefits of Passivation in an EJB container.
-
State the benefit of monitoring of resources in an EJB container.
-
Explain how the EJB container does lifecycle management and has the
capability to increase scalability.
Section 6: Protocols
-
Given a scenario description, distinguish appropriate from inappropriate
protocols to implement that scenario.
-
Identify a protocol, given a list of some of its features, where the
protocol is one of the following: HTTP, HTTPS, IIOP, JRMP.
-
Select from a list, common firewall features that might interfere with the
normal operation of a given protocol.
Section 7: Applicability of J2EE Technology
-
Select from a list those application aspects that are suited to
implementation using J2EE.
-
Select from a list those application aspects that are suited to
implementation using EJB.
-
Identify suitable J2EE technologies for the implementation of specified
application aspects.
Section 8: Design Patterns
-
From a list, select the most appropriate design pattern for a given
scenario. Patterns will be limited to those documented in Gamma et al. and
named using the names given in that book.
-
State the benefits of using design patterns.
-
State the name of a design pattern (for example, Gamma) given the UML
diagram and/or a brief description of the pattern's functionality.
-
Select from a list benefits of a specified design pattern (for example,
Gamma).
-
Identify the design pattern associated with a specified J2EE feature
Section 9: Messaging
-
Identify scenarios that are appropriate to implementation using messaging,
EJB, or both.
-
List benefits of synchronous and asynchronous messaging.
-
Select scenarios from a list that are appropriate to implementation using
synchronous and asynchronous messaging.
Section 10: Internationalization
-
State three aspects of any application that might need to be varied or
customized in different deployment locales.
-
Match the following features of the Java 2 platform with descriptions of
their functionality, purpose or typical uses: Properties, Locale,
ResourceBundle, Unicode, java.text package, InputStreamReader and
OutputStreamWriter.
Section 11: Security
-
Select from a list security restrictions that Java 2 environments normally
impose on applets running in a browser.
-
Given an architectural system specification, identify appropriate locations
for implementation of specified security features, and select suitable
technologies for implementation of those features.
