Question 1 Explanation:For SAP Enterprise Portal, the load-balancing solution should ensure session persistence,or “stickiness.” This means that all requests of a specific user in a single session areforwarded to the same server. Stickiness is achieved at initial logon, by linking to the IPaddress and local port of the load-balancing system. If one node fails, the other serversassume the tasks of the failed node without any pause in operation or loss of information.
Question 2 Explanation:Portal Content Directory (PCD) is a file system which stores roles and role components,and page-to-role relationships. It also stores deployable (PAR) and master iViews(written in Java) with their personalization data and derivations (Java iViews, ExternalServices). The PCD stores a copy of the page catalog.
Question 3 Explanation:The portal server needs read/write access to its PCD file system.
Question 4 Explanation:Roles are maintained with the Role Editor in both SAP Enterprise Portal 5.0 and 6.0. TheRole Editor is a Web-based tool for creating roles and hierarchies and for assigningcontent objects to roles. In EP 5.0, the Role Editor is a central tool which can be used tocreate and edit External Services, master iViews and worksets as well as roles. Othereditors are available for the administration of pages and iViews. In EP 6.0, the RoleEditor is embedded in the central administration environment for the development andadministration of content: the Portal Content Studio. This administration environment canbe used to call all editors for the creation and administration of content, including theRole Editor. Only roles can be created and edited in the Role Editor.
Question 5 Explanation:Authentication provides a way of verifying the user’s identity before he or she is grantedaccess to the portal. Once the user has been authenticated, he or she is issued a SAPlogon ticket that allows him or her to access all the applications, information and servicesin the Enterprise Portal using Single Sign-On. Since many of these applications maycontain sensitive data, it is imperative that the user in question can be identified and thisidentity authenticated.The process of authentication is based on each user having a unique set of credentials forgaining access. For example, with user ID and password authentication, theauthentication server compares a user’s authentication credentials with other usercredentials stored in a data repository. If the credentials match, the user is granted accessto the Enterprise Portal. Otherwise, the authentication fails and portal access is denied.The Enterprise Portal 5.0 offers the following integrated authentication mechanisms:· Authentication with User ID and Password· Authentication with X.509 digital certificates· Authentication using external mechanisms¡ Windows 2000 authentication¡ Authentication Against User Data in SAP R/3 System¡ External Web access management tools, such as Netegrity SiteMinder¡ COM interface allowing you to use any kind of external authentication serviceNote that you must use one method of authentication for all users. The only exception isauthentication with digital certificates. Digital certificates can be used as an additionalmethod of authentication. This means that users that have a client certificate use it to logon while other users have to provide credentials using a different authenticationmechanism.
Question 6 Explanation:The recommendation is that do not place more than fifty (50) objects in a single folder.
Question 7 Explanation:The Enterprise Portal Plug-In (WP-PI) enables the exchange of data between SAPEnterprise Portal and the mySAP.com components, for example SAP R/3 and SAP BW.It is a prerequisite to enable Drag&Relate and Single Sign-
Question 8 Explanation:The Page Builder assembles the pages that are displayed in the Enterprise Portal. It getsinformation about the navigation between pages and the layout of the pages from theroles assigned to a user. Information about which roles are assigned to which users isstored in the portal LDAP directory.
Question 9 Explanation:The operating system collector SAPOsCol is a stand-alone program that runs in theoperating system background. It runs independently of SAP instances exactly once permonitored host. SAPOsCol collects data about operating system resources, including:• Usage of virtual and physical memorySAP Enterprise Portal Fundamentals Certification questionsBy Aravindaaravind_sapep@yahoo.com• CPU utilization• Utilization of physical disks and file systems• Resource usage of running processes• Process monitoring
Question 10 Explanation:User access to content is determined by Role definitions. A portal role is a collection ofcontent. While portal content is developed to enable access to information relevant to theorganization in which the portal is deployed, roles define the subset of content availableto each functional role within the organization. Users are assigned to the role or roles thatprovide content relevant to them. A user has access to the content that has been assignedto all of his or her roles.
Question 11 Explanation:J2EE Engine cluster is a set of independent nodes that are addressed and managed as asingle system. The cluster consists of two types of nodes: dispatchers and servers. Theadministrator of the system determines the number of dispatchers and servers in a cluster.Each dispatcher node is connected to all server nodes in the cluster and each server nodemaintains connections to all other cluster nodes. Clustering enables dynamic loadbalancing by distributing client requests among the server nodes in the cluster, therebyproviding higher scalability and improved system performance
Question 12 Explanation:Users and passwords are defined in the directory server. To enable those users andpasswords for portal logon, you must define a security configuration, using the portaltools. However, in order to do so, you need to log on to the portal. The first time you logon to the portal, you log on as a default, predefined user, called admin, using the defaultpassword, admin. After you have defined a security configuration, you may continue tolog on as user admin, or you may log on with the user information defined in thedirectory server.The admin/admin logon provides you with access to the portal as a fully qualified superadministrator.Note that administrator access is enabled via Microsoft Internet Explorer browsers only.There is no administrator access via Netscape browsers.
Question 13 Explanation:Load balancing is dividing the work of one computer among several computers so thatmore work gets done in the same amount of time and all users get served faster. You canimplement a hardware or a software load balancing solution.
Question 14 Explanation:The role definition determines the navigation structure within the portal. The navigationstructure consists of the top-level navigation bar, and the detailed navigation tree. Thetop-level navigation bar is a series of tabs in the title area of the portal header. A usernavigates portal pages and services by clicking tabs in the top-level navigation bar.
Question 15 Explanation:When the user performs a Drag&Relate action in the front end, the client sends a HRNP(hyperrelational navigation protocol) request to the Unification Server through HTTP.The Unification Server resolves the relationship between the drag source and the droptarget, and queries the database and/or applications to determine the record set. Then itredirects the result set to the Portal Server and launches the screen which appears in thebrowser.
Question 16 Explanation:If you are using basic authentication, we strongly recommended that you set up thebrowser and portal Web server to communicate using Secure Sockets Layer (SSL).Otherwise users‘ credentials will be transmitted in clear text.
Question 17 Explanation:The SAP System has Release 4.0B or higher. SAP logon tickets are not supported inreleases lower than 4.0B.
Question 18 Explanation:Reverse Proxy Filter enables the portal to do the following:• Check all HTTP requests coming to the portal platform.• Distinguish between the following HTTP requests to the portal: those coming fromexternal sources, such as the Internet and outside the firewall of an enterprise, and thosecoming from internal sources, such as the intranet within the firewall.• Replace the scheme, host, and port number in an HTTP request.• Respond to more than one domain name using different proxy servers.
Question 19 Explanation:An iView is handled differently by Enterprise Portal depending on whether it is invokedfrom an Internet Explorer or Netscape browser. In Internet Explorer, each iView in aportal page is contained in an iFrame. Each iFrame is a distinct container, independent ofthe other containers. In Netscape, each iView is contained in an HTML table. Whenmultiple iViews are displayed in a portal page in Netscape, you are actually viewing asingle HTML page formatted into HTML tables.
Question 20 Explanation:Content Admin tab provides the tools for creating portal-related content, such as roles,iViews, pages, Web components.
Question 21 Explanation:Portal applications are configured according to the logger.xml configuration file. Variousportal applications place information into different log files. SAP recommend that you setlog levels in production environments to WARNING or ERROR.
Question 22 Explanation:SAP JCo is a middleware component that enables the development of SAP-compatiblecomponents and applications in Java. SAP JCo supports communication with the SAP server in both directions: inbound calls (Java calls ABAP) and outbound calls (ABAPcalls Java). So, SAP JCo realizes communication between the ABAP and the J2EEenvironments that can be used in SAP Web AS.
Question 23 Explanation:You use the cryptographic tool SAPGENPSE to generate a keystore in which you canstore a certificate. You only need this keystore for storing the root certificate of the portalWeb server. It is therefore not necessary that you send the generated certificate request toyour CA.
Question 24 Explanation:The entire portal administration is performed using administration roles contained in thestandard content of the portal. The administration roles contain all the functions possiblefor portal administration.The standard delivery of SAP Enterprise Portal 6.0 contains four administration roles, allof which subdivide the existing administration tasks into the following four groups:· Super Administration (containing all administration tasks)· Content Administration· System Administration· User Administration
Question 25 Explanation:You implement the Knowledge Management (KM) platform of the Enterprise Portal toenable unstructured content management, and sophisticated search and retrievalfunctionality over unstructured content in disparate information repositories. Theknowledge management platform also provides collaboration functionality, such assending messages, annotating documents, and setting up discussion groups.
Question 26 Explanation:
Question 27 Explanation:The Enterprise Portal iView interface enables you to create and manage portal channelsand iViews. When you open the interface, a list of iViews and channels is displayed,along with a set of tools that let you create and maintain channels and iViews. In thissection, we describe the main functions of this interface.iView Editor screen: (1) Search Tool, (2) Toolbar, (3) Channel List, (4) iView List
Question 28 Explanation:The user management component of the Enterprise Portal is an extensive applicationprogramming interface (API) that allows iViews to read data from the corporate LDAPdirectory and to read and write data to the portal LDAP directory. It also provides SingleSign-On functions and Authentication of portal users against user repository.
Question 29 Explanation:Single Sign-On (SSO) is a key feature of the Enterprise Portal that eases user interactionwith the many component systems available to the user in a portal environment. Once theuser is authenticated to the enterprise portal, he or she can use the portal to accessexternal applications. With SSO in the Enterprise Portal, the user can access differentsystems and applications without having to repeatedly enter his or her user informationfor authentication.The Enterprise Portal SSO mechanism is available in two variants depending on securityrequirements and the supported external applications:· SSO with SAP logon tickets· SSO with user ID and passwordBoth variants eliminate the need for repeated logons to individual applications after theinitial authentication at the enterprise portal. Whereas SSO with SAP logon tickets isbased on a secure ticketing mechanism, SSO with user ID and password forwards theuser’s logon data (user ID and password) to the systems that a user wants to call.
Question 30 Explanation:Channels, used to organize iViews into logical groups, are also assigned to roles. While every iViewmust be assigned to a channel, not every iView is associated with a page. A user has access to theiViews displayed on the pages in his or her portal. When personalizing portal pages, the user will alsohave access to the iViews in the channels assigned to his or her roles.
Question 31 Explanation:There is a permissions concept for portal objects in SAP Enterprise Portal 6.0. It is valid for all objectsof the Portal Content Directory that can be maintained with a special editor (Permission Editor) in theportal. Portal permissions mainly define the access rights of portal administrators to portal objects inthe Portal Catalog. The access permissions are implemented with the Access Control List (ACL)method.
Question 32 Explanation:In a load balanced landscape with multiple portal server installations the lock server is the portalcomponent that enables the components of the middleware layer to work concurrently with thepersistence layer, notably with the Portal Content Directory (PCD) and the database server.The middleware layer is installed as clients that access the persistence layer and the shared resources.Each middleware client must not interfere with other clients accessing and modifying the sameresources, therefore there is the need to implement a concurrent control mechanism.The control mechanism is a synchronization process over TCP/IP at port 3299. Through the port, thelock server identifies the specific process request coming from each middleware client. It then allowsaccess to the shared resources and the persistence layer. By so doing, each portal works with aconsistent view of the shared resources. Portals communicating with the lock server become the lockclients.
Question 33 Explanation:Web Dynpro is a browser-based, device-independent technology which provides a runtime and adevelopment environment for professional business Web applications. Web Dynpro delivers adeclarative meta-model to minimize the need to write programming code. From this abstract definition,Web Dynpro generates code to create a ready-to-run Web application.
Question 34 Explanation:The Enterprise Portal includes two user management master iViews that you can modify to suit yourcompany’s requirements and integrate in the portal. These are:· Self registration master iView: Allows users, for example, external users that do not exist in thecorporate LDAP directory, to register themselves as portal users.· Change password master iView: Allows users to change their password and optionally other userdata.
Question 35 Explanation:For the portal cluster:· To guarantee proper portal functionality, external load-balancing solutions must alwaysimplement stickiness, using either a source-IP or cookie-based distribution policy.· All machines in a portal cluster are covered by a license installed on any of them. However, forhigh availability purposes, you should install a license on at least two portal machines,although a license on each machine is recommended. In this case, if the machine with thesingle license is stopped for more than an hour (the period of time during which the license iscached), portal operation will not be interrupted.
Question 36 Explanation:My Pages tab contains the default Welcome page plus the pages assigned to all of the roles to whichthe logged on user is assigned. My Pages display iViews, small applications designed to retrieveinformation from various information resources.
Question 37 Explanation:
If you have a mixed system landscape including both SAP and non-SAP systems, we reकॉम mendthat you use a corporate LDAP directory as a primary store for central user data। Also use thisoption if you have a large number of users in your system landscape।In the above figure, a system running CUA is used to administer user data from several SAPABAP systems centrally। The user data from the CUA is synchronized with a corporate LDAPdirectory। The UMEs of any standalone J2EE Engines are configured to use the corporate LDAPdirectory as data source। Third-party systems can also access user data on the LDAP directory।
Question 38 Explanation:The Unification Server enables your Portal for Drag&Relate (hyperrelational navigation)। This meansthat you can relate business data across applications and/or databases for which you have installed aunifier on your Unification Server। Moreover the Unification Server provides functions to display datafrom the installed database unifiers।
Question 39 Explanation:To enable high load and avoid errors when running SAP Enterprise Portal with an Oracle database,increase the maximum number of processes and sessions in the database।
Make sure no one is currently using the database, as you must restart the database server.To change the number of processes on an Oracle database server:
1. From the Oracle program group in the Windows Start menu, go to Database Administration >DBAStudio, and log on to your Oracle database using DBA Studio as user SYSDBA.
2. Open the Database branch and choose: Instances > Database.
3. Choose All Initialization Parameters.
4. Scroll down the list of parameters to the processes property and increase its value (e.g. 150).
5. Verify the increase with your DBA.
6. Scroll down to the sessions property and increase its value to 1.2 multiplied by the number ofprocesses.
7. Choose OK and then Apply. You are prompted to restart the database server.
8. Restart the IIS and the Oracle server.Question 40 Explanation:When Single Sign-On with user ID and password is used, the user ID and password are transmitted inplain text using HTTP POST. We strongly reकॉमmend that you protect the connections to the SAPSystem using HTTPS or SNC to prevent the user ID and password being eavesdropped by an external party.
