Q11❓ MCQ📑 Lec 14Easy🔁Repeated⭐High-Yield
Within the Java Architecture for XML Binding (JAXB) framework, what are the formal definitions of Marshalling and Unmarshalling?
  1. A.Marshalling is validation of a document against a schema; Unmarshalling is schema compiling using xjc.
  2. B.Marshalling transforms an in-memory JAXB Java object tree into XML data; Unmarshalling converts XML data back into JAXB Java objects.
  3. C.Marshalling compiles XML elements to SQL tables; Unmarshalling maps database rows to Java fields.
  4. D.Marshalling compresses XML documents; Unmarshalling extracts the compressed content.

  1. A.Extensible Stylesheet Language Transformations
  2. B.Extensible Schema Language Transmitter
  3. C.XML Stylesheet Language Transformer
  4. D.Extensible Style Sheet Translation

In the context of the JAXP SAX parsing API, which of the following is the most accurate description of the `characters()` method defined in the `ContentHandler` interface?
💻 java Snippet
public void characters(char[] ch, int start, int length) throws SAXException { ... }
  1. A.A method of the W3C DOM API used to programmatically insert character data nodes into an XML document tree.
  2. B.A callback method of the SAX ContentHandler interface invoked by the parser to notify the application of the presence of character data.
  3. C.A helper method of the DOM interface used to replace an EntityReference node with its literal character data equivalent.
  4. D.A validation utility used in DTDs to enforce character length constraints on element content.

In which of the following scenarios is a developer most likely to choose a SAX-based parser over a DOM-based parser?
  1. A.You want to perform random-access traversals across siblings and parent relationships.
  2. B.The XML document is exceptionally large and memory constraints exist.
  3. C.When there is an absolute requirement to write modifications back to the source file.
  4. D.When the application needs to build a persistent in-memory visual tree representation.
Q15❓ MCQ📑 Lec 14Medium🔁Repeated⭐High-Yield💡Conceptual
Consider an application running in a highly memory- and speed-constrained environment that needs to parse XML documents and transmit the data to a high-configuration machine. Which parsing model is most appropriate for this context?
  1. A.Using a SAX-based approach is the best.
  2. B.Using a DOM-based approach is the best.
  3. C.Using an XSLT-based approach is the best.
  4. D.Using a database-bound ORM mapping is the best.
Q16❓ MCQ📑 Lec 14Medium🔁Repeated⭐High-Yield💡Conceptual
Consider an application running in a highly memory- and speed-constrained environment that needs to parse XML documents, sort their elements, and transmit the sorted data to a high-configuration machine. Which parsing model is most appropriate for this context?
  1. A.A platform-native language parsing approach without standard XML APIs.
  2. B.A DOM-based parsing approach.
  3. C.A SAX-based parsing approach.
  4. D.A combined DOM and SAX parsing pipeline.
Q17❓ MCQ📑 Lec 14Medium🔁Repeated⭐High-Yield💡Conceptual🌟Starred
An enterprise application needs to process an exceptionally large XML document to extract a small, targeted portion of its information. Given severe system memory constraints and high execution speed requirements, which of the following XML parsing approaches is most appropriate?
  1. A.Use SAX (Simple API for XML) to stream and filter the document elements sequentially.
  2. B.Use DOM (Document Object Model) to load the entire document structure into a traversable in-memory tree.
  3. C.Load the document into memory and apply an XSLT transformation template.
  4. D.Use a schema-based DOM builder factory to perform full validation before extraction.
Q18❓ MCQ📑 Lec 14Easy🔁Repeated⭐High-Yield💡Conceptual
JDOM is an open-source, Java-based parsing library designed to parse XML documents. JDOM is designed to work with which of the following standard parsing APIs?
  1. A.Only SAX APIs
  2. B.Only W3C DOM APIs
  3. C.Both SAX and DOM APIs
  4. D.Only StAX pull-parsing APIs
Q19❓ MCQ📑 Lec 14Easy🔁Repeated⭐High-Yield💡Conceptual
Which parsing approach or model does SAX (Simple API for XML) utilize to process XML documents?
  1. A.Event-based parsing (streaming event notifications sequentially)
  2. B.Tree-based parsing (building an in-memory node hierarchy)
  3. C.Query-based parsing (evaluating XPath expressions directly)
  4. D.Schema-based parsing (generating Java classes directly from XSD)
Q20❓ MCQ📑 Lec 14Easy🔁Repeated⭐High-Yield
What does the abbreviation **JAXP** stand for in the context of Java XML processing APIs?
  1. A.Java API for XML Processing
  2. B.Java Architecture for XML Parsing
  3. C.Joint Application for XML Processing
  4. D.Java API for XML Protocol
