1Z0-102 Exam Questions & Answers

Correct Answer: BDE

WebLogic Cluster Attributes includes:

B: * ClusterAddress Defines the address to be used by clients to connect to this cluster. This address may be either a DNS host name that maps to multiple IP addresses or a comma separated list of single address host names or IP addresses. If network channels are configured, it is possible to set the cluster address on a per channel basis.

D: The Message Mode of a cluster can be either Unicast or multicast.

E: Managed Servers are included in a WebLogic cluster.

Note: The config.xml file is an XML document that describes the configuration of a WebLogic Server domain. config.xml consists of a series of XML elements. The Domain element is the top- level element, and all elements in the Domain descend from the Domain element. The Domain element includes child elements, such as the Server, Cluster, and Application elements. These child elements may have children of their own. For example, the Server element includes the child elements WebServer, SSL and Log. The Application element includes the child elements EJBComponent and WebAppComponent.

Each element has one or more configurable attributes. An attribute defined in config.dtd has a corresponding attribute in the configuration API. For example, the Server element has a ListenPort attribute, and likewise, the weblogic.management.configuration.ServerMBean has a ListenPort attribute. Configurable attributes are readable and writable, that is, ServerMBean has a getListenPort and a setListenPort method.

Correct Answer: BE

B: To proxy requests by path, use the Location block and the SetHandler statement. When to use

Use to apply directives to content that lives outside the filesystem. For content that lives in the filesystem, use and . An exception is , which is an easy way to apply a configuration to the entire server.

For all origin (non-proxy) requests, the URL to be matched is a URL-path of the form /path/. No scheme, hostname, port, or query string may be included. For proxy requests, the URL to be matched is of the form scheme://servername/path, and you must include the prefix.

E: Add an IfModule block that defines one of the following:

For a non-clustered WebLogic Server instance:

The WebLogicHost and WebLogicPort parameters.

For a cluster of WebLogic Servers instances:

The WebLogicCluster parameter.

If you are proxying requests by MIME type to a cluster of WebLogic Servers, use the WebLogicCluster parameter.

For example:

WebLogicCluster

w1s1.com:7001,w1s2.com:7001,w1s3.com:7001

Note #1: The ... section is used to mark directives that are conditional on the presence of a specific module. The directives within an

section are only processed if the test is true. If test is false, everything between the start and end markers is ignored.

The test in the section directive can be one of two forms:

module name

!module name

Note #2:

Directive

Description: Applies the enclosed directives only to matching URLs Syntax: ...

Context: server config, virtual host

Status: Core

Module: core

The directive limits the scope of the enclosed directives by URL. It is similar to the directive, and starts a subsection which is terminated

with a directive. sections are processed in the order they appear in the configuration file, after the sections and .htaccess files

are read, and after the sections.

sections operate completely outside the filesystem. This has several consequences. Most importantly, directives should not be used to

control access to filesystem locations. Since several different URLs may map to the same filesystem location, such access controls may by circumvented.
