    Which option is true about session scope?

    • Objects are accessible only from the page in which they are created

    • Objects are accessible only from the pages which are in same session

    • Objects are accessible only from the pages which are processing the same request

    • Objects are accessible only from the pages which reside in same application

    Correct Answer
    A. Objects are accessible only from the pages which are in same session
    Explanation
    Session scope refers to the lifespan of an object in a web application. When an object is stored in session scope, it is accessible only from the pages that are in the same session. This means that the object can be accessed and manipulated by any page within the same session, but not by pages in different sessions. This allows for the sharing of data and information between multiple pages within a single session, providing a way to maintain state and pass data between different parts of an application.

    Attribute standalone="no" should be included in XML declaration if a document:

    • Has processing instructions

    • Is linked to an external XSL stylesheet

    • Has external general references

    • Has an external DTD

    Correct Answer
    A. Has an external DTD
    Explanation
    The attribute standalone="no" should be included in the XML declaration if the document has an external DTD. This attribute is used to indicate whether the document relies on an external DTD or not. By including standalone="no", it signifies that the document is not self-contained and requires the presence of the external DTD for proper validation and interpretation.

    Correct Answer
    A. Session_start()
    Explanation

    • Request

    • HttpRequest

    • HttpServletRequest

    • ServletRequest

    Explanation

    To use the external DTD we have the syntax:

    • <?xml version=”A.0” standalone=”no”?> <! DOCTYPE DOCUMENT SYSTEM “order.dtd”?>  

    • <?xml version=”A.0” standalone=”yes”?> <! DOCTYPE DOCUMENT SYSTEM “order.dtd”?>

    • <?xml version=”A.0” standalone=”no”?> <! DOCTYPE DOCUMENT “order.dtd”?>

    • <?xml version=”A.0” standalone=”yes”?> <! DOCTYPE DOCUMENT SYSTEM “order.dtd”?>

    Correct Answer
    A. <?xml version=”A.0” standalone=”no”?> <! DOCTYPE DOCUMENT SYSTEM “order.dtd”?>  
    Explanation
    The correct answer is "". This is the correct syntax for using an external DTD in an XML document. The "DOCTYPE" declaration specifies the type of document and the location of the DTD file. In this case, the DTD file is named "order.dtd" and it is located in the same directory as the XML document. The "SYSTEM" keyword is used to indicate that the DTD file is an external file. The "standalone" attribute is set to "no" to indicate that the document depends on the external DTD for its structure and validation.

    • <firstElement>some text goes here <secondElement> another text goes here</firstElement> </secondElement>

    • </firstElement>some text goes here </secondElement>another text goes here <firstElement>

    Correct Answer

    Consider the following statement containing regular expressions var text = "testing: 1, 2, 3"; var pattern = /\d+/g; In order to check if the pattern matches, the statement is

    • Text==pattern

    • Text.equals(pattern)

    • Text.test(pattern)

    • Pattern.test(text)

    Correct Answer
    A. Pattern.test(text)
    Explanation
    The correct answer is "pattern.test(text)" because the test() method is used to check if a pattern matches a string. In this case, the pattern is /\d+/g which matches one or more digits, and the string is "testing: 1, 2, 3". So, by using the test() method on the pattern with the string as the argument, we can determine if the pattern matches the string.
