Question 192mediummultiple choice

Study the full virtualization explanation →

A company uses a hypervisor to run multiple virtual machines on a single physical server. The host server has 64 GB of RAM. The administrator allocates 8 GB of RAM to each of 10 VMs, for a total allocation of 80 GB. The hypervisor utilizes memory overcommitment, which allows the total allocated memory to exceed the physical memory by sharing idle memory pages among VMs. Which of the following cloud computing characteristics does this configuration BEST demonstrate?

Question 193mediummultiple choice

A company operates a private cloud using a hypervisor cluster. The administrator wants to ensure that if a physical host server fails, the virtual machines running on that host are automatically restarted on other healthy hosts in the cluster with minimal manual intervention.

A company develops a custom web application that requires a specific runtime environment and middleware. The company wants to avoid managing the underlying servers, operating system patches, and runtime scaling. They choose a cloud service where they can upload their application code and the provider automatically handles the OS, runtime, and scaling based on demand. Which cloud service model does this describe?

A company uses a public cloud provider to host a critical database. The provider automatically replicates the data across multiple geographic regions to ensure data durability and availability. The company does not need to manage the underlying servers or storage infrastructure. Which cloud characteristic does this configuration BEST demonstrate?

Question 196mediummultiple choice

A company runs multiple virtual machines (VMs) on a single hypervisor host. The administrator wants to ensure that if one VM is compromised by malware, it cannot read the memory contents of other VMs running on the same host. Which hypervisor feature primarily provides this protection?

Question 197mediummultiple choice

A company runs its e-commerce website on a virtualized infrastructure. During a flash sale, the number of website visitors spikes dramatically. The virtualization platform automatically creates additional virtual web servers to handle the load and later terminates them when traffic returns to normal. This capability BEST illustrates which characteristic of cloud computing?

Question 198hardmultiple choice

Study the full virtualization explanation →

A company runs its customer-facing web application on a public cloud platform. The application experiences dramatic traffic spikes during promotional events. The cloud platform automatically increases the number of virtual server instances during high demand and reduces them when demand subsides. The company only pays for the compute resources consumed during the billing cycle. Which cloud computing characteristic does this configuration BEST exemplify?

Question 199hardmultiple choice

Study the full virtualization explanation →

A server administrator live-migrates a virtual machine (VM) from one hypervisor host to another within a cluster. After the migration, the VM powers on and the operating system boots, but it cannot communicate with any network resources. Other VMs on the destination host can communicate normally. The VM uses a virtual switch with a custom port group. Which of the following is the MOST likely cause of the network connectivity loss?

Question 200hardmulti select

A company runs its virtualized infrastructure on a cluster of hypervisor hosts. The administrator configures the cluster to automatically move virtual machines to other hosts in the event of a planned host maintenance, minimizing downtime. The administrator also wants to ensure that virtual machines are redistributed to balance CPU and memory utilization across the cluster periodically. Which two technologies or features are being utilized? (Select TWO.)
