Your new trainee is interested in ACLs (access control lists). He asks you want they can be used for. What should you tell him? A. Protect hosts from viruses. B. Classify network traffic. C. Provide high network availability. D. IP route filtering.

B. Classify network traffic.

D. IP route filtering.

Explanation:

An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.

Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification

Hence, an access control list primarily is composed of a set of permissions and operations associated with a network or file.

In Computer networking, access control lists (ACLs) can be used to perform the following tasks;

I. Classify network traffic: it can be used to classify the different networks on a router and define whether packets are rejected or accepted.

II. Internet protocol (IP) route filtering: any internet protocol (IP) address that's is not on the accept list would be refused permission into accessing a network. Thus, ACLs can either deny or accept IP addresses depending on the routing table configured on the router.

to change your username, you must:

1) make sure what the username you want to change to is allowed in this community

2) contact a administrator (for example, jaysl)

3) through pm, tell the admin what you want to change to

4) if the username is allowed, it will be changed in a matter of seconds (minutes at most)
