What is a major challenge of full mesh VPN topologies?

• A. They are straightforward and easy to implement
• B. They can be costly due to the number of connections
• C. They require the least amount of bandwidth
• D. They tend to have less secure connections

Answer: (B)

In a full mesh VPN topology, every site has a direct connection to every other site within the network. This setup provides excellent redundancy and can enhance performance since any two sites can communicate directly without the need to route traffic through a central hub. However, the primary challenge of this type of topology is its cost, which arises from the considerable number of connections that need to be established. In a full mesh configuration, if there are 'n' sites in the network, the number of connections required is calculated using the formula n(n-1)/2. This means that as the number of sites increases, the required connections grow exponentially, leading to significant infrastructure costs for setup and maintenance. These costs encompass not only the financial outlay for hardware and software but also the complexity involved in managing and configuring many individual connections. The other choices describe aspects of the topology that are not accurate: it is not considered straightforward or easy to implement due to the complexity involved (which rules out the first choice), and it typically does not require the least amount of bandwidth (refuting the third option). Additionally, while security can depend on various factors in a network, saying that full mesh VPNs tend to have less secure connections is misleading, as security is tied more closely
