CompTIA Network+ N10-009 Practice Question

Implementing network security lists specifically allows for granular control over traffic between resources, such as between web service and database servers, by defining rules that permit or deny traffic based on pre-set conditions, such as source and destination IP addresses, and port numbers. This method ensures that only authorized traffic can flow between the services, enhancing security without impacting other unrelated services. Using VLANs, while helpful in segmenting the network, often does not provide the depth of traffic filtering based on multiple conditions like network security lists do. Encryption enhances data security but does not control traffic flow. Relying solely on firewalls could be overextensive if the goal is to manage internal traffic between specific services within a protected environment.
