Which ACL can be used?

The answer to this is Dynamic. Take note that the engineer only wants to provide access to the user for a temporary period of time. This ACL can be effective in providing what the user needs for a limited amount of time. Take note that this type of ACL is associated with the user directory which means that it can be specified how long the user will have access to the session.

The moment that time runs out, the person will lose access to the data again. This ACL can also be used in order to block traffic at times. If the access list would need to be changed, the whole access list would have to be removed and then created to accommodate the users that will be given access temporarily.
