JN0-1103 Exam Dumps : Design - Associate (JNCIA-Design)

IPsec with NAT Traversal (NAT-T) encapsulates IPsec packets within UDP headers, adding additional overhead compared to standard IPsec. This results in higher packet overhead, which can affect performance and MTU handling more than other VPN protocols.

These elements directly impact port density and scaling requirements in a campus switching design. Understanding the number of unmanned devices, fixed user workstations with IP phones, and standalone VoIP phones is critical for calculating the total number of access ports needed and ensuring the infrastructure can support current and future capacity demands.

Secure Vector Routing (SVR) is specifically designed for SD-WAN environments with limited bandwidth, as it offers encrypted and policy-based routing with minimal overhead compared to protocols like IPsec or GRE. This makes it ideal for bandwidth-constrained branch sites.
