A . It is possible for more than two threads to deadlock at once. B . The JVM implementation guarantees that multiple threads cannot enter into a deadlocked state. C . Deadlocked threads release once their sleep（） method’s sleep duration has expired. D . Deadlocking can occur only when the wait（）， notify（）， and notifyAll（） methods are used incorrectly. E . It is possible for a single-threaded application to deadlock if synchronized blocks are used incorrectly. F . If a piece of code is capable of deadlocking， you cannot eliminate the possibility ofdeadlocking by insertinginvocations of Thread.yield（）.

A . A must contain all of the characters defined in B B . A must be Unicode C . The encoded values in A must match the encoded values in B for all characters defined in B D . A must be a multibyte character set E . The encoded values in A must match the encoded values in B for all numeric and alphabetic characters in B

A .  16 > 4 B .  16 / 2 C .  16 * 4 D .  16 >> 2 E .  16 / 22 F .  16 >>> 2

A .  Dense mode multicast requires explicit join messages from their members. B .  Dense mode multicast uses a push model to flood traffic throughout the network and then prunes the  unwanted traffic. C .  Sparse mode multicast uses a pull model to send multicast traffic to where it is requested.   D .  Sparse mode uses reverse path forwarding （RPF） to prune off redundant flows. E .  The primary use of sparse mode multicast is for test labs and router performance testing.

A .  An encapsulated， public class promotes re-use. B .  Classes that share the same interface are always tightly encapsulated. C .  An encapsulated class allows subclasses to overload methods， but does NOT allow overriding methods. D .  An encapsulated class allows a programmer to change an implementation without affecting outside code.

A . DPT/RPR uses a bi-directional ring consisting of two symmetric counter rotating fibre rings. B . DPT/RPR is defined in the IEEE 802.17 standard and it uses Token Bucket system to avoid collisions on the fiber. C . In DPT/RPR rings， data packets can be sent in one direction （downstream） and the corresponding control packets in the opposite direction （upstream），thus using both fibres concurrently to maximise bandwidth. D . DPT/RPR can be deployed in the Core of the SP networks where point-to-point POS links are used tomake best use of the Bandwidth.

A . It is possible for more than two threads to deadlock at once. B . The JVM implementation guarantees that multiple threads cannot enter into a deadlocked state. C . Deadlocked threads release once their sleep() method's sleep duration has expired. D . Deadlocking can occur only when the wait(), notify(), and notifyAll() methods are used incorrectly. E . It is possible for a single-threaded application to deadlock if synchronized blocks are used incorrectly. F . If a piece of code is capable of deadlocking, you cannot eliminate the possibility of deadlocking by inserting invocations of Thread.yield().

A . A finalizer may NOT be invoked explicitly. B . The finalize method declared in class Object takes no action. C . super.finalize（）is called implicitly by any over riding finalize method. D . The finalize method for a given objec twill be called no more than once by the garbage collector. E . The order in which finalize will be called on two objects is based on the order in which the two objects became finalizable.
