Which statement correctly describes the hierarchy of elements in an XML document?

Elements form a tree structure with one root element that contains all other elements.

An element can have multiple parent elements.

Elements are ordered sequentially, and the order of siblings is not significant.

Elements can overlap, but each element must have a unique name.

How is an XML namespace declared?

Using a special processing instruction at the top of the document.

By placing the namespace URI in the document's DOCTYPE declaration.

Using an xmlns attribute on an element, such as xmlns:prefix="URI".

By adding a schemaLocation attribute to the root element.

What is the primary purpose of an XML attribute compared to a child element?

Attributes are required for every element, while child elements are optional.

Attributes are used to define the structure of the document.

Attributes supply simple name-value metadata about an element, while child elements can contain complex nested data.

Attributes provide a way to include large blocks of text.

An engineer is parsing a Junos XML configuration with a script. The document has the following structure: router1 ge-0/0/0 . The engineer wants to extract the host-name using XPath. Which expression correctly navigates the hierarchy?

/configuration/system/host-name

/configuration/interfaces/host-name
