The Authentication Center (AC) is responsible for authenticating subscribers to the cellular network. Which of the following is NOT a function of the AC?0.5 MarksGenerating authentication challenges for subscribersStoring subscriber authentication credentialsRouting traffic between subscribers and the network Providing roaming services to subscribersValidating authentication responses from subscribers
Solution
One of the functions of the Authentication Center (AC) is generating authentication challenges for subscribers. This means that the AC is responsible for creating unique challenges that subscribers must respond to in order to prove their identity and gain access to the cellular network.
Another function of the AC is storing subscriber authentication credentials. This means that the AC keeps a record of the authentication information for each subscriber, such as their username and password or other authentication credentials.
The AC also has the function of routing traffic between subscribers and the network. This means that it acts as a middleman, directing the communication between subscribers and the cellular network, ensuring that the traffic is properly routed and delivered.
Providing roaming services to subscribers is also a function of the AC. Roaming allows subscribers to use their cellular services when they are outside of their home network, and the AC plays a role in facilitating this process.
However, validating authentication responses from subscribers is not a function of the AC. Once the AC generates an authentication challenge, it is the responsibility of other network elements, such as the Home Location Register (HLR) or the Visitor Location Register (VLR), to validate the subscriber's response and determine whether they should be granted access to the network.
