The correct answer is B. Increase network bandwidth on the multiplayer servers. An 800ms average ping indicates severe network latency degrading the gaming experience, and increasing network bandwidth is the first corrective action to reduce packet queuing and improve responsiveness.
Question
A cloud administrator works for an online gaming company that is hosting its multiplayer servers in a public IaaS cloud. The following metrics are reported during a controlled beta test:
RAM usage 80% Bandwidth usage 50% Average ping 800ms The beta test shows poor performance for gamers. Which of the following should the cloud administrator implement FIRST to improve the gamers' experience?
Options
- AScale the deployment of multiplayer servers by doubling the number of VMs.
- BIncrease network bandwidth on the multiplayer servers.
- CIncrease the RAM on the multiplayer servers.
- DDeploy multiplayer servers in public cloud locations closer to the user base.

Why each option
An 800ms average ping indicates severe network latency degrading the gaming experience, and increasing network bandwidth is the first corrective action to reduce packet queuing and improve responsiveness.
Doubling the number of VMs scales compute capacity but does not address the network bandwidth constraint that is contributing to high latency.
During the beta test, bandwidth sits at 50% with a limited user base, meaning that as player count scales to production levels, the network will become saturated and cause significant packet queuing delays. Queuing delay is a primary contributor to high latency in real-time multiplayer gaming. Increasing bandwidth on the existing multiplayer servers is the fastest first action to provide headroom for burst traffic and reduce the 800ms ping.
RAM at 80% is elevated but is not the cause of 800ms ping - memory pressure affects server-side processing throughput, not network round-trip time.
Deploying servers closer to users could reduce geographic latency, but this is a larger infrastructure undertaking compared to increasing bandwidth on existing servers and is not the FIRST action to take.
