During peak times, users are unable to access their online wealth management applications in a timely fashion. The online banking application resides in a community cloud environment. Which of the…

Memory ballooning is a hypervisor technique that uses a guest OS driver to reclaim idle memory from lightly loaded virtual machines and reallocate it to VMs under peak demand, directly addressing slowdowns caused by memory contention. In a community cloud hosting a wealth management application, concurrent user spikes can exhaust the memory allocated to application VMs, causing timeouts and slow response times. Ensuring memory ballooning is enabled gives the hypervisor the flexibility to satisfy peak memory demand without provisioning additional physical resources.

Insufficient disk space affects storage I/O and write operations but does not directly cause the application access delays users experience during concurrent peak load.

Routing all users through a single web endpoint does not address underlying compute or memory resource contention and could actually increase latency by concentrating traffic through one access path.

ACL misconfigurations cause access denial or authentication errors, not performance slowdowns - users who can reach the application at all are not being blocked by incorrect ACLs.
