INSTRUCTIONS: For each question, circle the answer of the one best choice. All questions count
equally.
1. What is a DTD, and why is it important?
A. It stands for Day-Time-Direction, and is used to tell the server what time zone and type of
language the browser uses.
B. It stands for Dom Tree Development, and it is used to tell Javascript what window to pop up,
depending on the time zone and whether the browser is Internet Explorer or not.
C. It stands for Dom Tree Dither, and tells the browser whether to use Internet Explorer or Apache.
D. It stands for Document Type Definition, and it is the part of the DOCTYPE that tells the browser
what version of HTML or XHTML was used to write the web page.
E. It stands for Dreamweaver Topic Descriptor, and it is used to tell Apache what the username and
password are.
2. What is wrong with this fragment of an XHTML web page:
<H1>CS-081 Rocks!</H1>

B. The closing tag should be <H1/>.
C. There should be no closing tag.
D. XHTML tag names have to be lower case.
E. The font attribute is missing.
3. How can you tell whether Firefox is interpreting a page in standards compliant mode or quirks
mode?

D. Use Tools Æ Options to turn standards compliant mode on or off.
E. View the page using Opera or Internet Explorer.
4. Trick question: What does Firefox do with the information from <?php to ?>.
A. This is a trick question because the PHP, running on the server, processes that information and
Firefox never sees it.
B. This is a trick question because <?php and ?> are handled by JavaScript, not Firefox.
C. This is a trick question because <?php and ?> are interpreted as alert() functions by Firefox.
D. This is a trick question because <?php and ?> are converted into Firebug commands by Internet
Explorer.
E. This is not a trick question at all: Firefox converts that information into PHP source code and
sends it to the server.
