CompTIA Updated 220-1101 Exam Questions and Answers by sage

M.2 SSD and NVMe interface are the best options for storage devices and interfaces that provide the best performance. M.2 SSD is a form factor that allows for faster data transfer and lower power consumption than traditional SATA SSDs. NVMe is a protocol that enables direct communication between the SSD and the PCIe bus, bypassing the SATA controller and reducing latency and overhead. Together, they offer the highest speed and efficiency for storage devices.

The best option to help the administrator secure the corporate resources is B. Biometric scanner.

A biometric scanner is a device that can authenticate a user’s identity based on their physical or behavioral characteristics, such as fingerprint, iris, face, voice, or signature. A biometric scanner can provide a high level of security and convenience for accessing corporate laptops, as it can prevent unauthorized users from accessing the devices and eliminate the need to remember passwords .

The other options are not the best options for this scenario. A Trusted Platform Module (TPM) is a chip that can store encryption keys and other sensitive data on a laptop. A TPM can enhance the security of data and devices, but it does not limit access to authorized users by itself. A TPM can work with a password or a biometric scanner to provide multifactor authentication . A laptop lock is a device that can physically secure a laptop to a desk or other object using a cable and a lock. A laptop lock can deter theft or tampering, but it does not prevent unauthorized users from accessing the laptop if they have the password or the key. Encryption is a process that can protect data on a laptop by transforming it into an unreadable format using a key. Encryption can prevent unauthorized users from accessing or modifying the data, but it does not prevent them from accessing the laptop itself.

High availability is a characteristic of cloud computing that prioritizes reliability. High availability means that cloud services can be accessed without interruption or failure, even in the event of a disaster or a hardware malfunction. This is achieved by using redundant components, backup systems, load balancing, and failover mechanisms. According to the CompTIA Core1 objectives, one of the benefits of cloud computing is high availability. A research paper on cloud reliability also defines high availability as the ability to provide continuous service despite faults or failures.

The correct answer is D. Identify the problem.

The first troubleshooting step that the technician should perform is to identify the problem. This means that the technician should gather information from the user and the system, and analyze the symptoms and the error messages to determine the nature and the scope of the issue. Identifying the problem can help to define the expected outcome, establish a theory of probable cause, and plan a course of action.

The other options are not the first troubleshooting steps, but they are part of the troubleshooting process that should be performed after identifying the problem. Establishing a plan of action (option A) means that the technician should devise a strategy to resolve the issue, based on the theory of probable cause and the available resources. Testing the theory (option C) means that the technician should verify if the theory of probable cause is correct, by performing tests or experiments on the system or its components. Documenting the findings (option B) means that the technician should record and report the results of each troubleshooting step, as well as the final solution and outcome.
