B: Hacker
Explanation:

Answer:
The blocking system.
Explanation:
In order to avoid servers to replicate with each other, I should configure the blocking system of the first DHCP.
For example, if the first DHCP fails to respond, the second will get in place, however, I have to configure the first system that immediately that the second DHCP starts working, the first blocks its information and use.
By this way, there won´t be any duplicated actions or reponses.
Answer:
b) Bounded Waiting
Explanation:
int currentThread = 1;
bool thread1Access = true;
bool thread2Access = true;
thread1 { thread2 {
While (true) {
While (true)
{
while(thread2Access == true)
{
while(thread1Access == true)
{
If (currentThread == 2) {
If (currentThread == 1)
{
thread1Access = false; thread2Access = false;
While (currentThread == 2);
While (currentThread == 1);
thread1Access = true; thread2Access = true;
} }
/* start of critical section */ /* start of critical section */
currentThread = 2 currentThread = 1
… ...
/* end of critical section */ /* end of critical section */
thread1Access = false; thread2Access = false;
… ...
} }
} }
} }
It can be seen that in all the instances, both threads are programmed to share same resource at the same time, and hence this is the bounded waiting. For Mutual exclusion, two threads cannot share one resource at one time. They must share simultaneously. Also there should be no deadlock. For Progress each thread should have exclusive access to all the resources. Thus its definitely the not the Progress. And hence its Bounded waiting.
Answer: Hot sites
Explanation:
Virtualization in the cloud computing is the technology that are useful for the hot sites. It basically making the virtual image of the network devices so that it can be easily use multiple machine at the similar time.
There are various types of benefits of the virtualization in the cloud computing are as follow:
- It protect the system from the system failure.
- It is the cost effective technology.
- By using this we can easily transfer the data from the physical storage to the virtual server.
