Question 1hardmultiple choice
Full question →A user reports intermittent network connectivity on a desktop computer. The technician observes that the Ethernet link light on the NIC turns off for a few seconds and then turns back on. The cable passes a wiremap test, the switch port is verified good with another device, and the NIC driver is updated. The issue occurs more frequently when the computer's case fan runs at high speed. Which of the following is the MOST likely cause?
Question 2mediummulti select
Full question →A workstation is unable to connect to the internet. The technician runs the 'ipconfig' command and sees the IPv4 address is 169.254.15.200 with a subnet mask of 255.255.0.0. The workstation can ping other devices on the local subnet but cannot ping the default gateway or any external addresses. Which TWO actions should the technician take to resolve this issue? (Select two.)
Question 3mediummultiple choice
Full question →A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?
Question 4hardmultiple 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 5hardmultiple 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 6mediummultiple 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?
Question 7mediummultiple 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 8easymultiple 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 9mediummultiple choice
Full question →A company hosts a critical web application using a public cloud provider. The application is deployed across two separate data centers in different geographic regions. The cloud provider automatically routes traffic to the healthy region in the event of a full data center outage, with no manual intervention. Which cloud computing characteristic does this BEST describe?
Question 10mediummultiple choice
Full question →A company implements a private cloud where multiple departments share the same physical hardware. The cloud platform ensures that each department's virtual machines are isolated from each other and that resources are dynamically allocated based on demand. Which cloud characteristic BEST describes this arrangement?
Question 11hardmultiple choice
Full question →A company hosts a critical web application on a public cloud provider. The architecture uses virtual server instances in two geographically separate data centers (regions). A global load balancer monitors the health of each region and distributes incoming user traffic. If an entire region becomes unavailable due to a natural disaster, the load balancer automatically redirects all traffic to the remaining healthy region. This design is intended to meet a specific business requirement. Which cloud characteristic does this architecture BEST demonstrate?
Question 12easymultiple choice
Full question →A company hosts its e-commerce website on a public cloud platform. During the holiday shopping season, traffic increases dramatically. The cloud platform automatically adds more virtual server instances to handle the increased load and then removes them when traffic returns to normal. Which cloud computing characteristic does this scenario BEST describe?
Question 13mediummultiple choice
Full question →A company must run a sensitive financial application that requires the application to be hosted on physical servers that are not shared with any other customer. The workload is highly variable and may require large amounts of resources for a few hours at a time. The company wants to minimize costs by paying only for the resources consumed. Which of the following cloud deployment models BEST meets these requirements?
Question 14hardmultiple choice
Full question →A company hosts a production database on a public cloud IaaS platform. The database requires consistent low-latency access to a storage volume that can be attached to a single virtual machine. The volume must persist independently of the VM's lifecycle, meaning data should remain intact even if the VM is stopped and started. The workload requires up to 10,000 IOPS. Which of the following cloud storage types should the technician configure to meet these requirements?
Question 15hardmultiple 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 16mediummultiple choice
Full question →A company subscribes to a cloud service that allows them to select a set amount of virtual CPU cores, RAM, and storage for their instances. They are billed monthly based on the total resources used, regardless of how many times they change the configuration. This billing model BEST represents which cloud computing characteristic?
Question 17hardmultiple 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 18hardmultiple 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 19easymultiple choice
