Question 1

What must you do when you provide a workaround for a code glitch in an existing service, for example, ProductService?Note: There are 3 correct answers to this question.

AModify the existing bean definition with the new service.

BAdd a new bean definition with a new ID for the new service.

CImplement a new custom service by extending the existing service.

DOverride the alias of the original bean definition.

EReplace all injections with a new ID for the new service.
The steps that you must do when you provide a workaround for a code glitch in an existing service, such as ProductService, are adding a new bean definition with a new ID for the new service, implementing a new custom service by extending the existing service, and overriding the alias of the original bean definition. These steps can help you create a custom service that overrides the default behavior of an existing service without modifying its source code. You do not modify the existing bean definition with the new service, nor do you replace all injections with a new ID for the new service, as these steps may cause errors or inconsistencies.

Answer : B, C, D

Question 2

What must you configure when you use the iFlow?Note: There are 2 correct answers to this question.

ASet iFlow authentication type to certificate-based.

BSet the receiver address setting and proxy type setting of the iFlow.

CAssign the AuthGroup.IntegrationDeveloper role to the SAP Commerce user.

DAssign the AuthGroup.IntegrationDeveloper role to the SAP Cloud Integration tenant.
The configurations that you must do when you use the iFlow are setting iFlow authentication type to certificate-based and setting the receiver address setting and proxy type setting of the iFlow. The iFlow is a graphical representation of an integration scenario between SAP Commerce Cloud and SAP Cloud Integration. It defines how messages are exchanged between these systems. You must configure the iFlow authentication type to use certificates for secure communication. You must also configure the receiver address setting and proxy type setting of the iFlow to specify how messages are sent to SAP Commerce Cloud.You do not assign the AuthGroup.IntegrationDeveloper role to the SAP Commerce user or to the SAP Cloud Integration tenant, as this is not related to using the iFlow.

Question 3

What are some of the benefits of using Service Layer Direct?Note: There are 3 correct answers to this question.

AIt allows you to read data from and write data to the database.

BIt bypasses the Jalo layer completely to persist data in the database.

CIt works for global sessions and for current sessions.

DIt combines the Jalo layer and service layer.

EIt bypasses the interceptors to persist data in the database.
The benefits of using Service Layer Direct are allowing you to read data from and write data to the database, bypassing the Jalo layer completely to persist data in the database, and bypassing the interceptors to persist data in the database. Service Layer Direct is a feature that allows the service layer to interact with the persistence layer more efficiently and use fewer resources. It can be enabled on an as-needed basis in your Java code or when invoking ImpEx.It does not work for global sessions and for current sessions, nor does it combine the Jalo layer and service layer.

Answer : A, B, E

Question 4

Which of the following does Product Support consider to be a workaround?Note: There are 2 correct answers to this question.

AThe support engineer provides guidelines on how to implement and configure a custom Spring bean overriding the default behavior in SAP Commerce.

BThe support engineer provides an alternative solution that resolves at least the basic processes of the affected feature.

CThe support engineer provides the customer with the official SAP Commerce patch that includes the fix.

DThe support engineer provides guidelines on how to modify the code of the affected feature.

Answer : A, D

Question 5

A new item type was added to an items.xml file named CarProcessDefinition. After the Ant build and SAP Commerce server startup, the following appears in the log file:15:56:54 **** [java] [m[0;31mERROR [main] [DefaultModelConverterRegistry] code CarProcessDefinition does not belong to known type. Maybe you have added a new type without updating your system.What does this message mean?

AThe new item has been added without specifying a deployment table.

BThe new item type will be created after a system update.

CThe new deployment table has been added without specifying a new item.

DThe Java class associated to the new item is missing.
The log message means that the new item type will be created after a system update. The message indicates that the code CarProcessDefinition does not belong to a known type, which means that the item type has not been registered in the system yet. This can happen when a new item type is added to an items.xml file but the system has not been updated to reflect the changes. A system update will create the new item type and its corresponding deployment table.The message does not mean that the new item has been added without specifying a deployment table, that the new deployment table has been added without specifying a new item, or that the Java class associated to the new item is missing.

Answer : B

Question 6

How do you persist changes to enable and disable JDBC logging?

ASAP Commerce Administration Console

BJava code

CConfiguration properties file

DBackoffice Administration Cockpit
The tool that you use to persist changes to enable and disable JDBC logging is configuration properties file. You can use this file to set various configuration parameters related to JDBC logging, such as jdbc.log.enable, jdbc.log.level, jdbc.log.file.path, or jdbc.log.trace. These parameters are persisted across server restarts and can be changed without modifying the source code.You do not use SAP Commerce Administration Console, Java code, or Backoffice Administration Cockpit to persist changes to enable and disable JDBC logging.

Answer : C

Question 7

You see the following entry in the thread dumps while analyzing a system's performance:ajp-8019- 43" nid=183 state=WAITING - waiting on <0x515a41f6> (a org.apache.tomcat.util.net.JIoEndpoint$Worker) - locked <0x515a41f6> (a org.apache.tomcat.util.net.JioEndpoint$Worker)at java.lang.Object.wait(Native Method)at java.lang.Object.wait(Object.java :485)at org.apache.tomcat.util.net.JioEndpoint$Worker.await(JioEndpoint.java :471)at org.apache.tomcat.util.net.JioEndpoint$Worker.run(JioEndpoint.java :497)at java.lang.Thread.run(Thread.java:662)Locked synchronizers: count = 0 How do you interpret this thread dump?

AThe Tomcat AJP parameter maxThreads is too small to handle simultaneous requests.

BThe JVM option maxAJPThreads is too small to handle simultaneous requests.

CThe thread is waiting for an incoming connection.

DThe system is about to crash because the thread is blocked and cannot perform its job.
The thread dump entry indicates that the thread is waiting for an incoming connection. The thread is part of the AJP connector, which communicates with a web connector via the AJP protocol. The thread is in a WAITING state, which means that it is waiting for another thread to perform an action. The thread is waiting on an object of type org.apache.tomcat.util.net.JIoEndpoint$Worker, which represents a worker thread that processes incoming requests.The thread dump entry does not imply that the Tomcat AJP parameter maxThreads is too small, that the JVM option maxAJPThreads is too small, or that the system is about to crash.
