Oracle 1Z1-899 실제 시험문제 및 답변

문제1
You have built a web application that you license to small businesses. The webapp uses a context parameter, called licenseExtension, which enables certain advanced features based on your client's license package.
When a client pays for a specific service, you provide them with a license extension key that they insert into the <context-param> of the deployment descriptor. Not every client will have this context parameter so you need to create a context listener to set up a default value in the licenseExtension parameter.
Which code snippet will accomplish this goal?

A. String ext = context.getInitParameter('licenseExtension')if ( ext == null ) { context.setInitParameter('licenseExtension' DEFAULT);}

B. String ext = context.getInitParameter('licenseExtension')if ( ext == null ) { context.resetInitParameter('licenseExtension' DEFAULT);}

C. String ext = context.getAttribute('licenseExtension');if ( ext == null ) { context.setAttribute('licenseExtension' DEFAULT);}

D. String ext = context.getParameter('licenseExtension');if ( ext == null ) { context.setParameter('licenseExtension' DEFAULT);}

E. You cannot do this because context parameters CANNOT be altered programmatically.
