20+ practice questions focused on Virtualization and Cloud Technologies — one of the most tested topics on the CompTIA A+ Core 2 220-1202 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Virtualization and Cloud Technologies PracticeA small business wants to migrate its on-premises file server to the cloud to reduce hardware maintenance costs. They need low-latency access for local employees and want to avoid egress fees for large data transfers. Which cloud deployment model best meets these requirements?
Explanation: A hybrid cloud combines private and public cloud resources, allowing sensitive or frequently accessed data to remain on-premises (private cloud) while using public cloud for scalability and backup. This reduces latency for local users and minimizes egress fees for large data transfers. Public cloud alone would introduce latency and egress costs; community cloud is for shared organizations; private cloud alone doesn't leverage cloud scalability.
A company uses a cloud-based SaaS application for customer relationship management (CRM). Several employees report that they cannot access the CRM this morning, but internet connectivity is working. The IT support team checks the cloud provider's status page and finds no reported outages. What should the technician check next?
Explanation: When a cloud service is accessible to some but not others, the issue is often local authentication or configuration. Expired credentials or browser cache problems are common causes. The cloud provider's status page shows no outage, so the issue is likely client-side. DNS and firewall settings would affect all users if misconfigured.
A technician is tasked with deploying a virtual machine for a new employee. The VM will run a Linux distribution and needs to be isolated from the corporate network but still have internet access for updates. Which network configuration should the technician choose for the VM?
Explanation: NAT (Network Address Translation) allows the VM to access the internet using the host's IP address while keeping it separate from the host's local network. Bridged mode would give the VM its own IP on the corporate network, violating isolation. Host-only mode blocks internet access. Internal network would also block internet access.
A user reports that their virtual machine running on a Type 2 hypervisor is extremely slow, especially during disk operations. The host machine has 16 GB of RAM and an SSD, but the VM is configured with 2 GB of RAM and a 100 GB dynamically expanding virtual hard disk. What is the most likely cause of the performance issue?
Explanation: Dynamically expanding virtual hard disks can cause performance degradation because they grow as data is written, leading to fragmentation and increased I/O overhead. Fixed-size virtual hard disks pre-allocate space, reducing fragmentation and improving disk performance. The RAM and CPU configuration are not directly related to the disk slowness described.
A technician is configuring a cloud-based backup solution for a company's critical data. The company wants to ensure that if the primary cloud provider experiences an outage, the data remains accessible from another provider. Which concept should the technician implement?
Explanation: Cloud federation allows different cloud providers to share resources and data, enabling failover and redundancy. This ensures data accessibility even if one provider goes down. High availability is a general concept, not specific to multi-provider redundancy. Load balancing distributes traffic but does not guarantee data access during a provider outage. Disaster recovery is a broader plan, but federation is the specific technology for inter-provider failover.
