NEW QUESTION 1
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.

NEW QUESTION 2
What is one of the benefits of using a federated repository over a user registry?

• A. Does notsupport identity profiles
• B. Supports only one registry in a realm
• C. Supports multiple registries within a realm
• D. Provides account and password policy support

Answer: C

Explanation:
Federated repositories enable you to use multiple repositories with WebSphere® Application Server. These repositories, which can be file-based repositories, LDAP repositories, or a sub-tree of an LDAP repository, are defined and theoretically combined under a single realm. All of the user repositories that are configured under the federated repository functionality are invisible to WebSphere Application Server.

• B. The applicationis automatically stopped, updated, and restarted.
• C. The application is only updated during the next restart of the application.
• D. The application is stopped, updated, and restarted at the scheduled time.

Answer: B

Explanation:
If the application is updated while it is running, WebSphere Application Server automatically stops the application, updates the application logic and restarts the application.

• A. Creating a new node for a web server adds a managed node.
• B. Creating a new node for a web server adds an unmanaged node.
• C. Adding a web server to an existing node created a managed node.
• D. Deleting a web server from an unmanaged node creates a managed node.

NEW QUESTION 6
In an IBM WebSphere Application Server cluster, an administrator notices EJB requests are not evenly distributed on the cluster members during the load test.
What two things can the administrator verify in order to identify and resolve the issue? (Select two.)

• A. Ensure Dynamic Workload Management is enabled.
• B. Ensure host scoped routing optimization is enabled.
• C. Ensure PMI Workload Management counters are enabled.
• D. Ensure each server in the cluster has an equal weighted value.
• E. Ensure the Web server plug-in is using the round robin algorithm.

Answer: AD

Explanation:
A: Workload management optimizes the distribution of client processing tasks. Incoming work requests are distributed to the application servers, enterprise beans, servlets, and other objects that can most effectively process the requests.
D: The server weighted round robin routing policy ensures a balanced routing distribution based on the set of server weights that have been assigned to the members of a cluster. For example, if all servers in the cluster have the same weight, the expected distribution for the cluster is that all servers receive the same number of requests. If the weights for the servers are not equal, the distribution mechanism sends more requests to the higher weight value servers than the lower weight value servers. The policy ensures the distribution that you want, based on the weights that are assigned to the cluster members.

• C. The time that the component was started in the application server.
• D. Data snapshots that store entire request and response bodies on the file system.

Answer: C

Explanation:
Cross Component Trace (XCT) annotates the logs so that log entries that are related to a request that is serviced by more than one thread, process, or even server are identified as belonging to the same unit of work.
XCT log records are typically added to the logs to:

NEW QUESTION 11
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.

• B. Verify that the administrator has Operator privileges.
• C. Verify the application placement controller is enabled.

NEW QUESTION 15
When deploying a new edition of an application, which edition rollout configuration option should be used to ensure that the two editions of the application are not active at the same
time?

• A. Atomic
• B. Grouped
• C. Soft reset
• D. Hard reset

Answer: A

Explanation:
Performing an atomic rollout to an edition replaces an edition on half of the cluster at a time to serve all user requests with a consistent edition of the application. All user requests are served by either the previous or the new edition; user requests are never served by both editions.
An atomic rollout ensures that all application requests are served by a consistent edition, for example, either edition 1.0 or 2.0, but not by both.

• C. Map a security role to the user/group for the application using the Integrated Solutions Console, save changes, and restart the application.
• D. Map a security role to the user runAs roles for the application using the Integrated Solutions Console, save changes, and restart the application.

Answer: C

Explanation:
WSRR defines J2EE roles that must be mapped to user or group principals. This can be done by using the WebSphere Administration Console

NEW QUESTION 23
What does the following JVM argument do?
-Xverbosegclog:${SERVER_LOG_ROOT}/verbose.m%d.7/18/16M%S.%pid.txt,20,10000

• A. It changes the default values for verbosegc logging.
• B. It changes the default location of the verbosegc logging.
• C. It configured verbosegc logging once it has already been enabled.
• D. It sets the default value for enabling and configuring verbosegc logging.

Answer: B

Explanation:
-Xverbosegclog[: <file> [,<X>,<Y>]]
Causes -verbose:gc output to be written to the specified file.
If it cannot create the file (for example, if an invalid filename is passed into the command), it will redirect the output to stderr.
If you specify <X>and <Y> the -verbose:gc output is redirected to <X> files, each containing <Y> GC cycles.
The dump agent tokens can be used in the filename. See Dump agent tokens for more information. If you do not specify <file>, verbosegc.%Y%m%d.%H%M%S.%pid.txt is used. example: -Xverbosegclog:newgclogname.log,7,10000
