ISC2 Certified Cloud Security Professional (CCSP) Practice Question

During a security review you are asked to harden the memory configuration of a new multi-tenant IaaS host that runs a Type-1 hypervisor. The cloud provider wants to minimize the risk that one tenant could retrieve data remnants or mount side-channel attacks that read another tenant's memory pages. Which hypervisor setting BEST meets this requirement?

  • Enable large memory pages (2 MB/1 GB) for all virtual machines to improve TLB efficiency

  • Disable inter-VM transparent page sharing and ensure pages are zeroed before re-allocation

  • Increase the hypervisor's memory overcommit ratio to reduce swapping

  • Permit kernel same-page merging across guests to conserve host memory
