A Direct Connect deployment needs more than 10 Gbps aggregate. How do you scale bandwidth on a single logical connection?
A.Request a 100 Gbps dedicated connection only
100G ports exist but LAG is the modular scale-and-resilience answer.
B.Link Aggregation Group (LAG) — bundle multiple DX connections into one logical link
Port aggregation = LAG. Correct.
C.Add a second VPN tunnel
VPN caps ~1.25 Gbps — not a scaling path for DX.
D.Enable jumbo frames
MTU affects frame size — not aggregate capacity.
Why this answer
DX LAG bundles up to 4 (or 2 for 100G) physical connections into a single logical link for aggregated bandwidth and failover — the standard scale-out for dedicated connections. Jumbo frames help per-flow throughput, not aggregate.
