How do you monitor virtual network adapter performance?
What will be an ideal response?
Hyper-V supports two types of network adapters: Hyper-V virtual network adapters, which are high-performance synthetic drivers, and Hyper-V legacy network adapters, which are low-performance emulated drivers. Performance Monitor provides counters for both of these adapters. Consider selecting the Bytes Received/sec and Bytes Sent/sec counters for these two adapters; each counter provides a measure of network traffic through the network adapter. In both cases, measurements are made across virtual networks that are created and bound to physical adapters in Hyper-V's Virtual Network Manager. If multiple virtual machines are running, the counter results may be aggregated across multiple virtual machines.

Which of the following statements is false?
a. Stream method map maps each element to a new value and produces a new stream with the same number of elements as the original stream. b. A reference is a shorthand notation for a lambda expression. c. ClassName::instanceMethodName represents a method reference for an instance method of a class. Creates a one-parameter lambda that invokes the instance method on the lambda’s argument and returns the method’s result. d. ClassName::new represents a constructor reference. Creates a lambda that invokes the no-argument constructor of the specified class to create and initialize a new object of that class.
There are two general approaches for mapping an association to a set of collections. In Section 10.6.2, we map the N-ary association Statistics to two classes, a simple Statistics class to store the attributes of the association, and a StatisticsVault class to store the state of the links among the association links. In Section 10.4.2, we described an alternative approach where the association links are stored in one or both classes at the ends of the association. In the event associations were stored in both classes, we added mutually recursive methods to ensure that both data structures remained consistent. Use this second approach to map the N-ary Statistics association to Collections. Discuss the trade-offs you encounter and the relative advantages of each approach.
