<span>On the computer there are always issues. For a developer to sit all day in front of a google that always invents things and the flashy images that disrupt everything. Googling on facebook is also an issue. Youtube, everything that contain flashy image is quite disruptive. If you think about content, maybe googling is less inventive. In a way it's nicer to buy applications but if you finally think of building it, there are always nicer ways of spending time. I prefer to go to seaside when I can.</span>
        
             
        
        
        
Answer:
Option (D) is the right answer.
Explanation:
DHCP term used as a short form of dynamic host configuration protocol, which is used to assigns the IP address automatically according to the network.
According to the scenario, the system is getting the wrong IP address that resulting in internet disconnection which is a failure of the DHCP server because it is responsible for assigning the right IP address to the system.
Hence option (D) is the most appropriate answer.
While other options are wrong because of the following reasons:
- Static IP is the type of IP address which is fix and doesn't change in the system after rebooting, hence it has no connection in the change of IP address.
-  If the DHCP server is working well there is no chance of interference from the surrounding device.
- Network setting has no connection with computer power supply as SMPS is used to give power and boot system only.
 
        
             
        
        
        
Answer:
Agentless NAC
Explanation:
An active directory is a kind of storage service that holds data of objects like user credentials, resource location etc, for permission and network access authentication.
Network access control is a form of computer network security that integrates security technology like antivirus, intrusion detection and prevention systems etc to system authorisation and authentication processes to control access to a network.
An agentless network access control uses the active directory to scan devices to confirm its compliance to security policies.
