Question 237
Which of the following is the best way to protect the data of a virtual machine in the event of hardware failure?
Correct Answer: C
Explanation The best way to protect the data of a virtual machine in the event of hardware failure is to use a cloud-based backup solution. A cloud-based backup solution is a service that copies and stores the data of a virtual machine to a remote server or storage device over the internet. A cloud-based backup solution can offer several benefits, such as: High availability and reliability: A cloud-based backup solution can ensure that the data of a virtual machine is always accessible and recoverable, even if the hardware that hosts the virtual machine fails or is damaged. A cloud-based backup solution can also provide redundancy and fault tolerance, by replicating the data across multiple locations or regions. Scalability and flexibility: A cloud-based backup solution can adapt to the changing needs and demands of the virtual machine, by allowing the user to adjust the backup frequency, retention period, and storage capacity. A cloud-based backup solution can also support different types of backup, such as full, incremental, or differential, depending on the user's preferences and requirements. Cost-effectiveness and simplicity: A cloud-based backup solution can reduce the cost and complexity of maintaining a backup infrastructure, by eliminating the need to purchase, install, or manage hardware, software, or licenses. A cloud-based backup solution can also automate and streamline the backup process, by providing easy-to-use tools and interfaces, such as web portals, APIs, or scripts. Other options, such as redundant hardware, UPS, or RAID, may improve the performance or resilience of the hardware that hosts the virtual machine, but they do not provide a complete protection for the data of the virtual machine in the event of hardware failure. Redundant hardware is a technique that uses multiple components or devices to perform the same function, so that if one fails, another can take over. UPS (uninterruptible power supply) is a device that provides backup power to a system in case of a power outage or surge. RAID (redundant array of independent disks) is a technology that combines multiple disks into a logical unit, to improve the speed, capacity, or reliability of the storage. However, these options may not prevent data loss or corruption due to other causes, such as human error, malware, or natural disasters. Therefore, a cloud-based backup solution is the best way to protect the data of a virtual machine in the event of hardware failure.

Question 238
A user built a new PC with parts sourced torn a popular online vendor. The system boots to the OS and basic browsing works, but whenever the user opens a 4K video or starts to play a game, the system Immediately shuts down. Which of the following is the MOST likely cause of this issue?
Correct Answer: B
Thermal paste is a substance that fills in any gaps between a CPU and its heat sink, which is a device that dissipates heat from the CPU. Without adequate thermal paste, the CPU may overheat and cause the system to shut down automatically to prevent damage. This is especially likely when running 4K video or games, which are more demanding and generate more heat. The technician should check if the CPU heat sink was attached properly and apply enough thermal paste to ensure good contact and heat transfer.

Question 239
Which of the following network devices would an administrator use to distribute traffic evenly throughout multiple nodes?
Correct Answer: A
A load balancer is a network device that distributes network or application traffic across multiple servers to ensure that no single server bears too much of the load. Load balancing helps to improve application availability, increase scalability, and optimize resource utilization. A bridge is used to connect two different networks, often to divide a larger network into smaller segments. A proxy server is used to forward client requests to other servers, and can also be used to cache frequently requested data. A switch is used to connect multiple devices within a network and to control the flow of network traffic. A firewall is used to secure a network by controlling incoming and outgoing traffic based on defined security rules. Reference: CompTIA A+ Core 1 Exam Guide, page 244.
