OKE - PCCET - 2.12 Define virtual private networks fully solved to pass 2023 What does a "A virtual private network (VPN)" creates? - correct answer a secure, encrypted connection (or tunnel) across the internet back to an organization's network. What is "Point-to-Point Tunneling Protocol (PPTP)"? - correct answer is a basic VPN protocol that uses Transmission Control Protocol (TCP) port 1723 to establish communication with the VPN peer and then creates a Generic Routing Encapsulation (GRE) tunnel that transports ncapsulated Point-to Point Protocol (PPP) packets between the VPN peers. Which "Transmission Control Protocol (TCP)" port number does PPTP use? - correct answer 1723 What is a "Generic Routing Encapsulation"? - correct answer Is a tunneling protocol developed by Cisco Systems that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links or point-to-multipoint links over an Internet Protocol network. What authentication protocols does the "PPTP" use to establish its tunnel? - correct answer - Password Authentication Protocol (PAP) - Challenge Handshake Authentication Protocol (CHAP) - Microsoft Challenge-Handshake Authentication Protocol versions 1 and 2 (MS-CHAP v1/v2), PAP and CHAP have vulnerabilities, which protocol should you best use to authenticate? - correct answer The Extensible Authentication Protocol Transport Layer Security (EAP-TLS) If we are talking about authentication in PPTP, why is setting up EAP-TLS as an authenticatio protocol more difficult? - correct answer requires a public key infrastructure (PKI) What is "Extensible Authentication Protocol Transport Layer Security (EAP-TLS)"? - correct answer is an Internet Engineering Task Force (IETF) open standard that uses the Transport Layer Security (TLS) protocol in Wi-Fi networks and PPP connections. What is a "Secure Socket Tunneling Protocol (SSTP)"? - correct answer is a VPN tunnel created by Microsoft to transport PPP or L2TP traffic through an SSL 3.0 channel For what is the "Secure Socket Tunneling Protocol (SSTP)"primarily used? - correct answer for secure remote client VPN access What is "Microsoft Point-to-Point Encryption (MPPE)"used for? - correct answer encrypts data in PPP-based dial-up connections or PPTP VPN connections. What protocol does "MPPE" use for encryption? - correct answer RSA RC4 what lengt in bits session keys does RSA RC4 support? - correct answer 40-bit and 128-bit session keys What is "OpenVPN"? - correct answer is a highly secure, open-source VPN implementation that uses SSL/TLS encryption for key exchange How much bit encryption does OpenVPN support - correct answer 256-bit encryption and can run over TCP or UDP What is "IPsec"? - correct answer is a secure communications protocol that authenticates and encrypts IP packets in a communication session. What does IPsec VPN require? - correct answer compatible VPN client software to be installed on the endpoint device.
