Ques 11 :
Which isolation level prevents dirty read in JDBC, connection class.
(A) TRANSACTION_READ_ COMMITTED
(B) TRANSACTION_UNREAD_ COMMITTED
Ques 12 :
Which of the following is true regarding not finding the java.sql.DriverManager class.
(A) This problem can be caused by running a JDBC applet in a browser that supports the JDK 1.0.2, such as Netscape Navigator 3.0. The JDK 1.0.2 does not contain the JDBC API, so the DriverManager class typically isn't found by the Java virtual machine running
(B) Most of the browsers cannot download java.* because of security reasons. Hence many vendors of all-Java JDBC drivers supply versions of the java.sql.* classes that have been renamed to jdbc.sql.*, along with a version of their driver that uses these modify
(C) Add import jdbc.sql.* in your applet code instead of java.sql.*, and add the jdbc.sql.* classes provided by your JDBC driver vendor to your applet's codebase, then all of the JDBC classes needed by the applet can be downloaded by the browser at run time,
(D) All of the above
