Question 2hardmultiple choice
Full question →A business uses a cloud service that automatically increases the number of virtual servers during peak traffic hours and decreases them during low usage, all without manual intervention. The policy is predefined in the cloud management console. This scenario best exemplifies which characteristic of cloud computing?
Question 3easymultiple choice
Full question →A cloud administrator can log into a web portal at any time, day or night, and immediately provision a new virtual server with the desired resources without having to contact the cloud provider's support team or wait for approval. Which essential characteristic of cloud computing does this scenario BEST describe?
Question 4mediummultiple choice
Full question →A cloud administrator configures a virtual machine so that it automatically increases its allocated CPU and RAM resources during peak demand and reduces them during low usage periods without any manual intervention. Which cloud computing characteristic does this configuration BEST represent?
Question 5hardmultiple choice
Full question →A cloud administrator is migrating a virtual machine from a private cloud to a public cloud. The VM must retain its hostname and IP address. The public cloud provider does not support the same hypervisor as the private cloud. Which of the following migration methods is MOST appropriate?
Question 6mediummultiple choice
Full question →A cloud administrator needs to increase the amount of RAM allocated to a running virtual machine (VM) from 4GB to 8GB to handle a temporary workload spike. The administrator logs into the cloud management console, selects the VM, and changes the instance type to one with 8GB of RAM. The change takes effect immediately without requiring a reboot. Which cloud computing characteristic does this scenario BEST illustrate?
Question 7easymultiple choice
Full question →A cloud provider hosts virtual servers for multiple clients on the same physical hardware. Each client's data and applications are logically isolated from others, and the clients have no knowledge of where their resources are physically located. This is an example of which essential characteristic of cloud computing?
Question 8mediummultiple choice
Full question →A cloud provider houses multiple customers' virtual machines on the same physical server hardware. Each customer's data and applications are logically isolated, and customers have no knowledge or control over exactly which physical resources they are using. This scenario best describes which essential characteristic of cloud computing?
Question 9easymultiple choice
Full question →A cloud provider offers a service where customers can provision virtual servers with varying amounts of CPU, RAM, and storage on-demand. Customers are billed only for the actual resources they consume each hour, with no upfront commitment. This cloud characteristic is known as:
Question 10mediummultiple choice
Full question →A cloud provider tracks a customer's usage of storage, processing power, and network bandwidth on a per-hour basis. At the end of the month, the customer receives a bill that exactly matches the resources consumed. Which essential cloud characteristic does this scenario BEST illustrate?
Question 11mediummultiple choice
Full question →A cloud service provider uses a Type 1 hypervisor to host multiple tenant virtual machines on a single physical server. This allows the provider to serve many customers from the same infrastructure while maintaining isolation. Which essential characteristic of cloud computing does this best represent?
Question 12hardmultiple choice
Full question →A company currently hosts its own on-premises email server. To reduce hardware maintenance overhead, they decide to move the email server to the cloud. They require the ability to install and manage their own email application (e.g., Microsoft Exchange), including the underlying operating system, while the cloud provider is responsible for the physical infrastructure and virtualization layer. Which cloud service model best meets these requirements?
Question 13mediummultiple choice
Full question →A company decides to migrate its on-premises customer relationship management (CRM) software to the cloud. They want to avoid managing the underlying servers, operating systems, and runtime environments. They also want to focus only on configuring the CRM application to meet their business needs. Which cloud service model should they choose?
Question 14easymultiple choice
Full question →A company hosts a legacy application on a virtual machine. The application's license is tied to the MAC address of the virtual machine's network interface. The administrator needs to migrate the VM to a different host server without breaking the license. Which of the following virtualization features should the administrator use?
Question 15hardmultiple choice
Full question →A company deploys a stateless web application on multiple virtual machines in a public cloud behind a load balancer. The application experiences unpredictable traffic spikes. During a spike, the load balancer distributes requests evenly, but users report that they are randomly logged out or lose session data such as shopping cart contents. The application is designed to store session state locally on each server. Which of the following should the administrator implement to resolve this issue?
Question 16mediummultiple choice
Full question →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?
Question 17hardmultiple choice
Full question →A company develops a web application that relies on a custom library available only for a specific Linux distribution. They want to deploy the application in the cloud with minimal administrative overhead, but they need full control over the software stack, including the ability to install the custom library and configure the web server. Which cloud service model BEST meets these requirements?
Question 18hardmultiple choice
Full question →A company has a legacy virtual machine running on a deprecated hypervisor (Hyper-V). They want to migrate this VM to a new hypervisor (VMware vSphere) hosted in a private cloud while preserving the VM's configuration, installed applications, and data. The migration must be performed with minimal downtime. Which of the following methods is MOST appropriate?
Question 19mediummultiple choice
Full question →A company has a router with four Ethernet ports. They need to connect 12 wired devices in the same LAN segment. All devices must receive IP addresses from the same DHCP server running on the router. Which device should the technician add?
Question 20mediummultiple choice
Full question →A company hosts a critical application on a public cloud platform. The IT team configures the application to run on multiple virtual machines in an auto-scaling group. The cloud platform monitors the health of each instance. If a health check fails, the platform automatically terminates the unhealthy instance and launches a new one to maintain the desired capacity. Which cloud concept does this configuration BEST illustrate?
Question 21hardmultiple choice
Full question →A company hosts a critical application on a public cloud provider. The solution is designed with a set of pre-configured virtual machines that are kept powered off in a different availability zone. In the event of a failure in the primary zone, the standby VMs are automatically started, and traffic is rerouted. This design primarily addresses which of the following cloud computing characteristics?
Question 22mediummultiple choice
Full question →A company hosts a critical application on two virtual machines located in different availability zones within the same cloud region. Both VMs are active and running simultaneously. The application is designed such that if one VM fails, the other continues serving traffic without any downtime. Which cloud concept does this configuration BEST demonstrate?
Question 23mediummultiple choice
Full question →A company hosts a critical database on a virtual machine in a public cloud. The database requires persistent storage that must be retained even if the VM is terminated. The storage must also be accessible from multiple VMs simultaneously for a future high-availability configuration. Which type of cloud storage BEST meets these requirements?
