Content filtering is a technique that blocks or allows access to certain types of web content, based on predefined criteria or policies. Content filtering can be used to comply with the cease-and-desist order by preventing users from accessing torrent sites or downloading torrent files, which are often used for illegal file sharing or piracy. Content filtering can also protect the network from malware, phishing, or inappropriate content.

OSPF (Open Shortest Path First) is a link-state routing protocol that uses an administrative distance of 110. This means that OSPF routes are preferred over routes from other routing protocols, such as RIP (Routing Information Protocol), which has an administrative distance of
120.
BGP (Border Gateway Protocol) is a path vector routing protocol that uses an administrative distance of 200. EIGRP (Enhanced Interior Gateway Routing Protocol) is a hybrid routing protocol that uses an administrative distance of 90.
Static routes have an administrative distance of 1.

Explanation
Hub-and-spoke is a network topology where each node connects to a central switching device, such as a hub or a switch. All traffic between the nodes must pass through the central device, which acts as a single point of communication and control. Hub-and-spoke topology is simple, easy to manage, and cost-effective, but it also has drawbacks, such as low redundancy, high latency, and scalability issues.

A service-level agreement (SLA) is a document that states what the minimum performance expectations are within a network, such as uptime, throughput, latency, and security. An SLA is usually signed between a service provider and a customer, and it specifies the penalties or remedies if the service level is not met
