Connecting an infected device can lead to ransomware encrypting the local machine and potentially spreading across the network. Typically this is inadvertent – a member of staff unwittingly plugs in an infected USB drive, which encrypts their endpoint – but it can also be deliberate.
Network Access Control (NAC) examines the current state of network device before it is allowed to connect to the network. Any device that does not meet a specified set of criteria is only allowed to connect to a “quarantine” network after the security deficiencies are corrected. NAC Prevents computers with sub-optimal security from potentially infecting other computers through the network. This technology uses, protocols such as Dynamic Host Configuration Protocol (DHCP) server and Address Resolution Protocol (ARP).
Answer:
A) The developer must supply a comparator object belonging to a class that implements the Comparator interface
Explanation:
The comparator interface handles the ordering (sorting) of user-defined classes, it does this by comparing two different objects from different classes. The comparator interface works by accepting a method which extracts a key for sorting of a type say N, and returns a comparator that compares to N, it therefore compares the object (current one) with the specified one
