Correct Answer: C
ccna book 200-125 pdf.Scalability --------VPN enables companies to use the Internet Service Provider's (ISP) Internet infrastructure. This makes it easy to add new users, so companies can significantly increase capacity without adding significant infrastructure.One-by-one VPN compatible broadband technology allows mobile workers, telecommuters, and those who need to work longer hours to access the corporate network using a high-speed broadband connection, providing staff with great flexibility and efficiency. High-speed broadband connections provide a cost-effective solution for connecting to remote offices.8.1.1.2 Types of VPNsIn simple terms, a VPN connects two endpoints (for example, two remote offices) on a common network to form a logical connection. These logical connections can be built at Layer 2 or Layer 3 of the 0SI model. Based on these logical connection models, VPN technologies can be broadly classified as Layer 2 VPNs and Layer 3 VPNs o Establishing connectivity between sites through a Layer 2 or Layer 3 VPN is the same. The load is preceded by a delivery header that allows it to reach the destination site. This chapter focuses on Layer 3 VPN technology.Common Layer 3 VPNs are GRE, MPLS, and IPSeco Layer 3 VPNs can be point-to-point site connections, such as GRE and IPSec, or they can use MPLS to establish any-to-any connections to many sites.GenericRoutingEncapsulation (GRE) was originally developed by Cisco and later standardized as RFC 1701. The IP delivery header for GRE is defined in RFC 1702. A GRE tunnel between two sites that are reachable by 1P can be described as a VPN, because the private data between the sites is encapsulated in a GRE delivery header.MPLS, developed by Cisco, was originally called tag switching and later standardized by the IETF as MPLS. more and more service providers are deploying MPLS to provide MPLSVPN services to their customers. MPLSVPN uses tags to encapsulate raw data or load to form a VPNoHow can network administrators protect data from eavesdropping in a VPN? Encrypting data is one way to protect it. Data encryption can be achieved by deploying encryption devices at each site. IPSec is a cluster of protocols developed with the support of the IETF to implement security services over IP packet-switched networks. The Internet is the most popular public network for packet switching, so an IPSec VPN deployed on the public Internet± can save a company a significant amount of money compared to a dedicated VPN.IPSec services provide authentication, integrity, access control and confidentiality. With IPSec, information exchanged between remote sites can be encrypted and authenticated. Both remote access VPNs and site-to-site VPNs can be deployed using IPSec.8.1 VPN 221
