Question 25 – Objective 5 – Infrastructure/Technology Architecture
Scalability is an important part of your clustering architecture design. You want to ensure that
EJB method calls made from your clustered web applications to your clustered EJB components
are evenly load balanced across all available members. Which architecture design below
describes how this is accomplished?

clustered EJB components are co-located on the same server. Use the
HTTPClusterServlet for even load balancing and failover of EJB calls.

clustered EJB components are co-located on the same server. Use the EJB’s replica
aware stub for even load balancing and failover of EJB calls.
c) Split your cluster into two separate tiers, one tier for your clustered web applications, and
the other tier for your clustered EJB components. Use the EJB’s replica aware stub for
even load balancing and failover of EJB calls.
d) Use a single tier cluster architecture where both you clustered web applications and
clustered EJB components are co-located on the same server. Use a web server plugin
for even load balancing and failover of EJB calls.
e) Split your cluster into two separate tiers, one tier for your clustered web applications, and
the other tier for your clustered EJB components. Use a web server plugin for even load
balancing and failover of EJB calls.
Question 26 – Objective 5 – Infrastructure/Technology Architecture
You are using a JMS file store as your persistent message store. It is critical that transactional
safety and reliability be maintained for your persistent store as other components of your
architecture depend upon this. You must also ensure that the JMS persistent mechanism scal
well. Knowing this, what synchronous write policy attribute value will you specify for the file store
configuration?
a) Disabled
b) Cache-flush
c) Direct-write
d) Flush on commit
e) Write on commit
Question 27 – Objective 5 – Infrastructure/Technology Architecture
You use many enterprise portal desktops as the composite applications tier of your architecture.
You have determined that the best way to scale these applications and handle increasing
capacity demands is to cluster them. Given the current tools available for portal replication in a
cluster and your architectural layout, what is the best option for propagating portal data
throughout your cluster when moving the portal application from QA to production?
a) Propagate data from the source server in QA to the admin server in the production
cluster. Let the admin server propagate the data to each managed server.
b) Propagate data from the source server in QA to each managed server in the cluster
since the admin server will not propagate portal data.
c) Use the provided database scripts to copy data from the QA portal database to the
database that will be used by the production portal application.
d) Write a custom database script to copy data from the QA portal database to the
database that will be used by the production portal application.
e) Use JMX to copy the portal application data from the QA domain directly to the
production domain than synchronize the data and redeploy the portal application.
Question 28 – Objective 1 – Architectural Vision
Which description below best defines the purpose of the presentation services layer of SOA?
a) The layer providing access to services combining diverse and disparate enterprise data
from multiple sources throughout the enterprise.
b) Provides the orchestration an assembly of services into application components or entire
applications.

interface.
d) Implements orchestration and coordination logic.
e) Provides a uniform, coupled API.
Question 29 – Objective 1 – Architectural Vision
As you begin to plan your SOA implementation it becomes clear to you that governance is going
to be a big concern. Specifically you must decide who will be responsible for the development,
design and equally as important, funding of services and service infrastructure. You need to
minimize issues or ownership, access, buy in and not maintaining architectural standards. What
is the most appropriate governance model to use in accomplishing this?
a) Federated model
b) Partially federated model
c) Hierarchical model
d) Federated hierarchy model

portlets on multiple platforms. Which technology below will allow you to do this while allowing
the portlets to integrate with the host platform at the application level?
a) WS-I
b) WSRP
c) Java Portlet API
d) WS-Portlet
e) Screen scraper utilities
Question 31 – Objective 3 – Information Systems Architecture–Applications
When sending a message to multiple end points the decision on when to apply the data
transformation is crucial. If you transform too early you possibly waste time transforming a
message that didn’t need it. If you transform too late you run the risk of service failure when
sending a message. What SOA design pattern ensures that message transformation is done at
the correct time?
a) Basic Asynchronous Stateless 2 Way design pattern.
b) Basic Asynchronous Stateful 2 Way design pattern.
c) Message Fan Out design pattern.

system. The module will also manage tokens and handle single sign-on across multiple pages.
This module must be used in stand alone web applications and portlets. You must make the
module as cohesive and reusable as possible. What is the best way to accomplish this?
a) Implement the login module logic as a Custom Control.
b) Implement the login module logic using a built in login control.
c) Implement the login module logic using a portlet backing file.
d) Implement the login module logic using a nested page flow.

to create additional service architecture to handle synchronous clients. What design pattern
could you implement that would allow you to support asynchronous calls by synchronous clients
without designing additional infrastructure?
