Which VPN protocol is known for its strong security and is widely used for site-to-site VPNs?
Look for the protocol that combines tunneling with strong encryption standards.
L2TP combined with IPsec provides strong encryption and is commonly used for secure site-to-site VPN connections. PPTP is outdated and less secure. OpenVPN is secure but more often used for remote access. SSTP is Microsoft-specific and less common for site-to-site.
Which VPN type is best suited for a company that wants to allow employees to securely connect to the company network from home?
Think about VPNs that connect individual users to a network remotely.
Remote access VPNs allow individual users to connect securely to a company network from remote locations such as home. Site-to-site VPNs connect entire networks. Extranet VPNs connect business partners. Intranet VPNs are internal.
Given these VPN protocols, which one generally provides the strongest encryption and is considered the most secure?
Consider the encryption algorithms and protocol security history.
OpenVPN with AES-256 encryption is widely regarded as very secure. PPTP is outdated and vulnerable. L2TP without IPsec lacks encryption. SSTP uses SSL 3.0, which has known vulnerabilities.
A user wants a VPN that balances good security with fast connection speeds for streaming. Which VPN protocol is most suitable?
UDP-based protocols often offer better speed than TCP-based ones.
OpenVPN over UDP offers a good balance of security and speed, making it suitable for streaming. PPTP is fast but insecure. L2TP/IPsec is secure but slower. SSTP is secure but generally slower due to TCP overhead.
Match the VPN type to its primary use case:
- 1. Site-to-site VPN
- 2. Remote access VPN
- 3. Extranet VPN
- 4. Intranet VPN
Which option correctly pairs the VPN types with these use cases?
Think about who is connected in each VPN type: offices, employees, partners, or internal users.
Site-to-site VPN connects branch offices (1). Remote access VPN connects individual employees (2). Extranet VPN connects business partners (3). Intranet VPN is for internal use within an organization (4).
