B.
Switch to Standard Network Tier for non-critical internet traffic
C.
Provision Cloud Interconnect for on-premises data transfers
D.
Compress all data using Cloud KMS before sending
E.
Move all VMs to a single zone to avoid cross-region egress
F.
Use Cloud NAT for all outbound traffic
How to approach this question
Identify GCP features that specifically lower the per-GB cost of data transfer.
Full Answer
Implement Cloud CDN to cache media files at the edge, Switch to Standard Network Tier for non-critical internet traffic, Provision Cloud Interconnect for on-premises data transfers
Network egress costs can be optimized by: 1) Cloud CDN (serves from cache, avoiding region egress charges), 2) Standard Network Tier (cheaper per-GB routing for internet traffic), and 3) Cloud Interconnect (offers discounted egress rates for hybrid traffic compared to public internet).
Common mistakes
Thinking Cloud NAT (F) reduces costs.
