Ralph, the administrator of a 500-node private internetwork, is devising a plan to connect the network to the Internet. The primary objective of the project is to provide all of the network users with access to web and email services while keeping the client computers safe from unauthorized users on the Internet. The secondary objectives of the project are to avoid having to manually configure IP addresses on each one of the client computers individually and to provide a means of monitoring and regulating the users' access to the Internet. Ralph submits a proposal calling for the use of private IP addresses on the client computers and a series of proxy servers with public, registered IP addresses, connected to the Internet using multiple T-1 lines. Which of the following statements about Ralph's proposed Internet access solution is true?

Study Notes
Here are the study notes:
Networking Appliances, Applications, and Functions
- Firewall: a device located between two networks that restricts incoming and outgoing traffic; capable of service-dependent filtering, stateful packet inspection, and deep packet inspection.
- Router: a device that connects two networks together, forwarding traffic between them as needed.
- Switch: a device that connects multiple devices within a network, forwarding packets to the intended recipient.
- Hub: a simple network device that connects multiple devices, repeating incoming data signals to all connected devices.
- Bridge: a device that connects two networks, forwarding packets between them based on MAC addresses.
- Proxy Server: a device that acts as an intermediary between a client and a server, providing anonymity and security.
- Load Balancer: a device that distributes incoming network traffic among multiple servers to improve responsiveness and availability.
- IDS/IPS: a system that monitors network traffic for signs of unauthorized access or malicious activity.
Network Security
- NAT: a technique that allows multiple devices to share a public IP address when accessing the Internet.
- Stateful Packet Inspection: a firewall feature that tracks the state of network connections to ensure only authorized traffic is allowed.
- Deep Packet Inspection: a firewall feature that examines the contents of packets to identify and block malicious traffic.
- Intrusion Detection/Prevention Systems (IDS/IPS): systems that monitor network traffic for signs of unauthorized access or malicious activity.
Network Protocols and Technologies
- Fibre Channel: a high-speed storage networking technology used in SANs.
- iSCSI: a protocol that allows SCSI commands to be sent over TCP/IP networks.
- FCoE: a protocol that enables Fibre Channel packets to be transmitted over Ethernet networks.
- SAN: a dedicated high-speed network for storage devices, providing block-level access.
- NAS: a device that provides file-level access to shared files over a network.
Network Architecture and Design
- Multilayer Switch: a device that operates at multiple OSI layers, providing routing, switching, and other functions.
- Unified Threat Management (UTM) Appliance: a device that integrates multiple security functions, including firewalling, antivirus, and intrusion detection.
- Virtual Private Networking (VPN): a technology that enables secure, encrypted connections over the Internet.
- Quality of Service (QoS): a technique for ensuring network traffic is prioritized and managed to meet performance requirements.
Other Networking Concepts
- Content Filtering: a feature that blocks access to specific websites or content based on administrator-defined rules.
- Load Balancing: a technique for distributing incoming network traffic among multiple servers.
- CGN: a technique for extending the availability of IPv4 addresses using NAT and other technologies.
- DoS/DDoS: types of attacks that overwhelm a network or system with traffic in order to make it unavailable.
