QUESTION NO: 1
Assume that a certain XMLDB has an HTTP listener function, and can receive XML documents via HTTP protocol.
In this case, the XMLDB follows [Procedure] below to identify the character encoding method of the XML document received.
[Procedure]
(1) If the XML document character encoding method can be determined from the HTTP request header, process the XML document character encoding according to the HTTP request header information.
(2) If the XML document character encoding method cannot be determined from the HTTP request header, identify the character encoding from the XML document itself
Select which is correct as the identified character encoding resulting from the procedure above when the XMLDB receives a well-formed XML document according to [Conditions] below. Assume that the XMLDB follows RFC3023.
[Conditions]
The actual character encoding method for XML document is “UTF-16;” however, no XML
declaration is specified.
The HTTP request header defines “Content-Type: text/xml.” however, the charset parameter is not defined in this Content-Type header field.
A. US-ASCII
B. UTF-8
C. UTF-16
D. The character encoding method is determined from system locale, and is therefore
undetermined
Answer: A
QUESTION NO: 2
Consider the structure of XML when storing date information as XML data. You must aggregate data for each calendar year from this XML data.
Assume that statistical values related to the storage and retrieval of date information in a certain XMLDB is as follows:
[Date Information XML Structure A]
2007-04-OK/date>
[Date Information XML Structure B]
2QQ741
[Statistical Values] (assumed)
The search for one date node (XML structure A) or one y node (XML structure B) takes one microsecond in either case, regardless of search path.
With respect to structure A, two microseconds are required for each date node to determine whether the date element value matches the search year.
With respect to structure B, one microsecond is required for each y node to determine whether they element value is the same as the search year value.
The number of date elements at the initial state is 2000.
The number of date elements will increase with future updates; however, this is not a
consideration for this question.
Insertion of a new date element under structure A takes 10 microseconds.
Insertion of a new date element under structure B takes 20 microseconds.
Do not consider any facts or conditions other than those noted above.
When the average number of new date element insertions per month is 20, and the average number of calendar date information searches per month is 10, which is the most effective XML structure in improving overall execution efficiency for insertions and searches?
A. XML Structure A
B. XML Structure B
C. Under these conditions, both are equivalent
Answer: B
QUESTION NO: 3
Assume that a certain XMLDB can perform a validation check using DTD when inserting an XML document. Select two of the following that are unsuitable when using the xml:id attribute to manage the uniqueness of XML document elements.
Assume that the XMLDB can properly process the xml:id attribute, and that an error is reported when a violation of the xml:id specification occurs.
A. The xml:id attribute can be defined as the ID type using DTD
B. Duplication errors in the values of the xml:id attribute cannot be detected unless a validation check is performed
C. Duplications may occur in the values of the xml:id attribute when combining two XML
documents (neither having errors related to xml:id attributes) into one XML document
D. Duplication errors in the values of the xml:id attribute cannot be detected when the XMLDB does not support XML namespaces
Answer: B,D
