Port 9081 must be available for a default WebSphere Portal Test Environment installation. This is the default port used by WebSphere Portal for the test environment server. Port 9080 is typically used for production environments, while 8080/8081 are common HTTP ports but not the WebSphere Portal defaults.

An active credential performs a login on behalf of a client without exposing the secret to the client's code or application. This pattern enhances security by keeping credentials server-side while still allowing authentication. The term 'active' refers to the credential actively performing the login action transparently.

JSR168 portlet custom tags are not prefixed with a fixed string like 'portlet', 'portal', or 'portletAPI'. The prefix depends entirely on the taglib definition in the portlet's deployment descriptor and tag library descriptor files. Developers define their own prefixes in the taglib directive.

The numeric value in the expiration-cache tag is measured in seconds. An expiration-cache value of 10 means the portlet output is cached for 10 seconds before regenerating. This is the standard unit for cache expiration in the JSR168 portlet specification.

The fmt:setBundle tag in JSTL uses the 'basename' attribute to specify the resource bundle. This basename represents the fully qualified name of the resource bundle (minus the .properties extension). The other options (bundlefile, bundlename, basefile) are not valid attributes for this tag.

Microsoft's 'Oslo' was the codename for a set of Service-Oriented Architecture (SOA) technologies focused on model-driven development and visualization tools. This included the 'Oslo' repository, modeling language (M), and related tooling. Option C is correct. 'Dolly,' 'Azure' (which became Microsoft's cloud platform), and 'Wolverine' do not correspond to Microsoft's SOA technology codename.

Microsoft's codename for their ASP.NET AJAX framework implementation was 'Atlas.' This was the official internal name during development before being branded as ASP.NET AJAX when released for the .NET Framework 2.0. Option A is correct. 'Bullet,' 'Katmai' (a SQL Server codename), and 'Jolt' are not associated with ASP.NET AJAX.

Silverlight 1.0, Microsoft's first release of their rich web application plugin framework, carried the internal codename 'Jolt' during development. Option C is correct. 'Jasper' was a Microsoft data access codename, 'Paxos' is not associated with Microsoft Silverlight, and 'Burton' does not correspond to known Microsoft codenames for this product.

jQuery is famously marketed with the slogan 'Write Less, Do More' because it simplifies JavaScript programming with its concise syntax and powerful methods. Silverlight is a Microsoft framework for rich internet applications, JavaScript is the programming language itself, and HTML is the markup language.

Microsoft Silverlight is the correct answer as it was a web application framework designed to provide rich interactive multimedia capabilities similar to Adobe Flash. Silverlight supported animations, vector graphics, and audio/video playback. Microsoft Atlas was an advertising platform, AJAX is an asynchronous web technology, and Expression is a design tool suite.

Bing is Microsoft's current web search engine, launched in 2009 to replace Live Search. MSN Search was the earlier name for Microsoft's search service, while Wikipedia is an encyclopedia platform, not a search engine.

Microsoft Search Server (MSS) is the correct answer as it was an enterprise search platform built on SharePoint Server's search capabilities. WSS is the free Windows SharePoint Services, MOSS is the broader SharePoint Server platform, and Bing Services refers to web search.

Windows SharePoint Services (WSS) is correct as it was the free add-on version providing basic portal functionality for Windows Server 2003 and 2008. MSS and MOSS were paid enterprise editions, while Bing Services is unrelated to SharePoint.

HTML stands for Hyper Text Markup Language, which is the standard markup language for creating web pages. This makes option A correct. Options B, C, and D propose incorrect expansions that don't represent the actual meaning of HTML in web development and markup languages.

W3C (World Wide Web Consortium) is the international standards organization that develops protocols and guidelines for the World Wide Web. It was founded by Tim Berners-Lee and ensures the long-term growth and interoperability of web technologies. The other options are private companies or incorrect statements about web standards.

HTML headings use tags from
