23. The requirement is not to have any downtime for the application clients when redeploying a new version
of the application. Existing clients will be given certain amount of grace time beyond which the new version
should prevail. Which of the following approaches would you prefer if you are supposed to deploy the new
version of the application?
A. Use a command similar to weblogic.Deployer… “-redeploy…-name appname -appversion newappver”
and “-undeploy -appversion oldappver” later to undeploy
B. Use a command similar to weblogic.Deployer… “-redeploy…-name appname -appversion newappver

24. Which of the following is false regarding auto-deployment?
A. If auto-deployment is enabled, when an application is copied into the /autodeploy directory of the
Administration Server, the Administration Server detects the presence of the new application and deploys it
automatically
B. If you delete application files from the /autodeploy directory when the admin server is not active,
managed servers will still detect that the application files were deleted and will undeploy the application
C. When you switch from the development mode to production mode, any applications that were previously
deployed via the /autodeploy directory remain deployed; if you wish to undeploy or redeploy such
applications after you have switched to production mode, you must undeploy or redeploy them manually
D. When an application has been auto-deployed in the exploded archive format, the Administration Server
periodically looks for a file named REDEPLOY in the exploded application directory. If the timestamp on this
file changes, the Administration Server redeploys the exploded directory
E. Production mode disables the auto-deployment feature and prevents any applications you place in the
/autodeploy directory after you switch to production mode from being deployed
Answer: B

11. Langham Rudolph, a large industrial manufacturing firm, has a procurement department that serves the
purchasing needs for over 14 manufacturing sites. These sites were acquired over a period of time, and
operate with disparate legacy systems that serve a variety of requirements beyond just purchasing. It
takes an average of 20 minutes to log off one site and log on to another site, and each site maintains its
own set of purchasing rules and part numbering system. Thus, purchasers will typically process all
requirements for a single site before moving onto the next one this will often take up to a whole day.
This system unfortunately did not handle priorities well customer purchasing requirements could be held
up as much as 14 days if it was at the end of the list.
How should this problem be solved, balancing effectiveness and time to implement? Choose two of the
following:
A. The purchasing department should be sent a list of orders to expedite and dedicate one or more
resources to spend the extra time switching between systems and expediting.
B. Shared business services should be written to replace the legacy systems for all purchasing functions.
This will provide a unified part numbering format and purchasing rules.
C. A composite application should be written to pre-login and communicate across all legacy systems,
automatically translating between part numbers and rules, but re-using each legacy systems existing local
rule base.
D. A presentation service should be written to sort orders by priority and part type.
Answer: CD
12. Best Tech, inc. is a national retailer of consumer electronic goods. Their stores have been dealing with
supply problems. Best Techs central distribution department allocates goods to stores based on weekly
forecasts calculated by their inventory system. These forecasts are based on monthly batch files sent
from the stores that contain sales history. The marketing department sometimes runs flash promotions
which causes a run on a particular product. The forecasters usually account for this, but they dont account
for complementary products, or products that may be nearby in the store layout that become whim
purchases. As such, Best Tech stores are often out of stock on many popular items. Other times, Best
Tech stores and regional warehouses are flooded with inventory that they dont need.
While there are several solutions to this problem, what would be the optimal solution for BestTech to handle
sales of complementary products, considering SOA best practices?
A. Service enable the forecast feeds so they can be sent on a more frequent basis.
B. Service-enable point of sale and inventory: All sales from the point of sale system should invoke a
shared business service that logs the sale, so the forecasters have up-to-the-second planning information
C. Service-enable a pull supply chain: All sales from the point of sale system should invoke a shared
business service that immediately orders a new part from the warehouse. This in turn invokes a service at
the regional distributor, which then invokes a service at the supplier.
D. Service-enable the local store and regional warehouse inventory systems, so the planning department
can, in real time, request inventory status from several stores at once to gain a more accurate single view to
drive forecasts.
Answer: C
13. An order entry service is deployed on a .NET based cluster, callable through SOAP over HTTP, with an
expected response time of 1.5 seconds, and guaranteed exactly once message delivery using

A. Implementation
B. Interface
C. Contract

version will be deployed to a new URL endpoint. How should this change be handled?
A. All dependents should move to the new URL
B. All dependents can continue use the existing URL; maintain parallel implementations at the new and
existing URL.
C. An intermediary should be provided to adapt the interface from the existing URL to the new URL

Answer: C
16. An information and access service is created to standardize message-oriented access to a relational
database. Several batch file feeds go directly to the database and bypass the service interface. What is
the most appropriate long term action?
A. Batch feeds must be re-designed at their source systems to instead use messages
B. None. Direct batch feeds do not have any drawbacks in an SOA.
C. The batch files should be routed through the service interface as large messages.
D. The service interface should be designed to handle both message-oriented and streamed data access.
Answer: D
17. An information and access service is being harvested from an existing application. This service
returns relatively small data sets. It requires high-speed, low-latency access from services within its own
physical infrastructure, as well as moderate-latency access from physically remote services. How should
this be handled to ensure the service can be re-used and evolved autonomously?
A. Provide the same logical service interface for all transports or access paths, but allow different contracts
to be used between them.
B. Provide a separate logical service interface for each transport or access path.
C. Provide a separate service implementation for each transport or access path.
D. Provide the same logical service contract for all transports or access paths, but allow different
implementations to vary between them.
Answer: A

19. Several shared business services are implemented by an application with a sophisticated and highly
intertwined code base. These business services need to use each other at times. What is the impact of
allowing this collaboration to occur within the implementation without forcing it to communicate through the
explicit service interface? Choose the correct answer with the broadest implication.
A. The implementation, when it evolves, will break the service interface.
B. Communicating through a service interface is inefficient; it is best to allow the collaboration to occur
within the implementation.
C. The shared business services would effectively be a managed as a single service, as they are tightly
coupled to a single implementation and must evolve together.
D. Collaborations cannot be managed or monitored through service infrastructure if they do not
communicate through the service interface.
