Exam 200-301 topic 1 question 991 discussion

Never heard of these SMH.

Here we go again. Cisco will give you 3 correct answers and ask for the best 2 out of the 3. Cisco is not really concerned if you can implement or repair their technology only that you fail the test the first, maybe more, times around. I think AB is correct. C is technically correct too. https://www.cisco.com/c/dam/en/us/products/collateral/ios-nx-os-software/enterprise-class-teleworker-ect-solution/prod_brochure0900aecd80582078.pdf chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://www.cisco.com/c/dam/en/us/products/collateral/ios-nx-os-software/enterprise-class-teleworker-ect-solution/prod_brochure0900aecd80582078.pdf

1. **GETVPN (Group Encrypted Transport VPN)**: - GETVPN is a scalable solution for large-scale deployments, particularly suitable for enterprises with multiple branch offices. It allows for secure communication between multiple sites, using a centralized key management approach, and it scales well because it does not require full mesh IPsec tunnels between every branch. GETVPN is ideal for large-scale site-to-site VPNs. 2. **DMVPN (Dynamic Multipoint VPN)**: - DMVPN is a highly scalable, flexible VPN solution that is ideal for large networks with dynamic and remote branches. It allows for direct communication between branch offices without requiring dedicated point-to-point tunnels. DMVPN uses GRE (Generic Routing Encapsulation) and IPsec to create a secure and scalable mesh VPN network, which makes it a good choice for multiple branch offices.

DMVPN and GETVPN is not within the scope of the CCNA

A & B are correct

A. GETVPN (Group Encrypted Transport VPN): GETVPN is a Cisco VPN technology that provides secure and scalable VPN connectivity for multiple branch offices and large-scale deployments. It uses a group-based encryption mechanism to encrypt traffic between sites, allowing for efficient and scalable encryption across the network. GETVPN is particularly suitable for deployments with high bandwidth requirements and complex routing environments. B. DMVPN (Dynamic Multipoint VPN): DMVPN is another Cisco VPN technology designed for scalable and dynamic VPN deployments. It allows for the creation of secure overlay networks over public or private WAN connections. DMVPN provides efficient and scalable connectivity between multiple branch offices by using a combination of IPsec, GRE (Generic Routing Encapsulation), and NHRP (Next Hop Resolution Protocol). It simplifies the configuration and management of VPN connections, making it well-suited for large-scale deployments.

DMVPN and FlexVPN are more commonly recommended by Cisco for large-scale VPN deployments, GETVPN can be a viable alternative in certain situations where a tunnel-less VPN solution is desirable. Ultimately, the choice between these VPN technologies will depend on specific requirements and factors, such as the underlying network topology, transport technologies, and security policies
