How can an administrator configure Web services security?

• A. Customize WS-Security policy set and bindings and attach to Web services.
• B. Configure global security with LDAP authentication and map the configuration to Web services.
• C. Request application developer to use Web Services Security API to achieve Web services security.
• D. Enable the Web ServicesMetadata Exchange (WS-MetadataExchange) protocol to enable message-level security.

Answer: C

Explanation:
The Web Services Security specification provides a flexible framework for building secure web services to implement message content integrity and confidentiality. The Web Services Security service programming model supports this flexible framework by providing extension points to integrate new token formats, and methods to obtains keys needed for message protection. The application server programming model provides Web Services Security programming application programming interfaces (WSS API) for securing SOAP messages.
Note: WS-Security is a message-level standard that is based on securing SOAP messages through XML digital signature, confidentiality through XML encryption, and credential propagation through security tokens. The Web services security specification defines the facilities for protecting the integrity and confidentiality of a message and provides mechanisms for associating security-related claims withthe message.

• A. Cookies
• B. LTPA Token
• C. Rest Services
• D. URL Rewriting
• E. HTTP Response codes

Answer: CE

Explanation:
Representational State Transfer (REST) is a lightweight framework for designing
applications that use HTTP to make calls. REST uses HTTP to perform the Create, Read, Update, and Delete (CRUD) operations between client and server. Applications interactwith the services by using HTTP, POST, PUT, GET, and DELETE operations.

NEW QUESTION 6
When installing a new application to IBM WebSphere Application Server, which location is valid for the application file?

• A. Client Machine
• B. Managed Node
• C. Unmanaged Node
• D. Remote Web Server

Answer: B

Explanation:
Configuration file location during application installation
Several things occur upon installation of an application onto WebSphere Application Server:
Note: A node is a logical grouping of managed servers. Nodes can be managed or unmanaged. An unmanaged node does not have a node agent or administrative agent to manage its servers, whereas a managed node does. Both application servers and supported web servers can be on unmanaged or managed nodes.

NEW QUESTION 8
What determines which On Demand Routers (ODRs) a Web server forwards requests to?

• A. The default order in theODR_Module_Routing_Poilicy.xml.
• B. The configuration scope determines which ODRs are included inhttpd.conf.
• C. The configuration scope determines which ODRs are included inplugin-cfg.xml.
• D. The configuration scope determines which ODRs are included inHTTPplugin-cfg.xml.

Answer: C

Explanation:
In a topology with a web server which forwards requests to an on demand router (ODR), the ODR can be set to dynamically generate and update the web server plug-in configuration file plugin-cfg.xml. By configuring an ODR to dynamically update plugin- cfg.xml, you avoid manually updating the file during administrative actions, which can affect the content.

NEW QUESTION 16
Through what protocol can a Java client directly access EJBs running on an application server?

• A. JDBC
• B. RMI/IIOP
• C. SOAP/JMS
• D. SOAP/HTTP

Answer: D

Explanation:
Provided that it uses the correct protocols (SOAP, HTTP, WSDL), any web service client can access a stateless session bean, whether ornot the client is written in the Java programming language. The client doesn’t even “know” what technology implements the service: stateless session bean, JAX-WS, or some other technology. In addition, enterprise beans and web components can be clients ofweb services. This flexibility enables you to integrate Java EE applications with web services.

NEW QUESTION 20
An administrator has deployed an application that uses 30 unique SQL statements with a maximum data source connection pool size of 10.
What is the recommended prepared statement cache size for the application?

• A. 10
• B. 30
• C. 40
• D. 300

Answer: B

Explanation:
To determine the highest value for your cache size to avoid any cache discards, add the number of uniquely prepared statements and callable statements, as determined by the SQL string, concurrency, and the scroll type, for each application that uses this data source on a particular server. This value is the maximum number of possible statements that can be cached on a given connection over the life of the server. Setting the cache size to this value means that you never have cache discards. In general, configure a larger cache for applications with a greater number of statements.
