CompTIA A+ Practice Test Set 2 Of 7

The best way for the technician to handle the situation is to contact the customer and give an estimated arrival time. This shows professionalism and consideration for the customer's time. It allows the customer to adjust their schedule accordingly and reduces any frustration or inconvenience caused by the technician's delay. It also demonstrates good communication skills and helps maintain a positive relationship with the customer.

The PING command is used to determine if there is a connection to a specified IP address and also measures the response time. By sending a small packet of data to the specified IP address and waiting for a response, the PING command can determine if there is a connection and calculate the time it takes for the response to be received. This is useful for troubleshooting network connectivity issues and measuring the latency of the connection.

Scheduling regular system backups is the best means of ensuring that data is not lost. Regular backups create copies of data and store them in a separate location, providing a safety net in case of data loss due to hardware failure, accidental deletion, or other unforeseen events. By regularly backing up data, organizations can restore lost information and minimize the impact of data loss on their operations. Deploying a RAID system and securing servers are important measures, but they do not guarantee data preservation as effectively as regular backups.

A technician would find a telephone wire on the RJ-11 connector. The RJ-11 connector is commonly used for connecting telephones and modems to a telephone line. It typically has six positions and two or four conductors, which are used for transmitting voice signals over the telephone network. The RJ-11 connector is not used for fiber, RS-232, or coaxial cable connections.

RDP (Remote Desktop Protocol) is commonly used for Windows Remote Desktop. It allows users to connect to and control a remote computer over a network. NTP (Network Time Protocol) is used for time synchronization, PPTP (Point-to-Point Tunneling Protocol) is used for creating VPNs, and LDAP (Lightweight Directory Access Protocol) is used for accessing and managing directory information. However, none of these protocols are specifically designed for Windows Remote Desktop like RDP is.

The clicking sound coming from the computer indicates a potential issue with the hard disk drive. The fact that Windows fails to load and displays a file not found error further supports this possibility. Therefore, the hard disk drive should be tested first to determine if it is the cause of the crashing issue.

A docking station would be the best device to address this issue. A docking station allows the customer to connect multiple devices to their laptop simultaneously by providing additional ports. This would enable them to connect their keyboard, mouse, monitor, and scanner all at the same time, providing a convenient and efficient solution for their work in the office.

Windows 2000 and XP have a maximum FAT32 volume size limit of 32GB. This means that the operating systems can recognize and work with FAT32 volumes up to this size. Volumes larger than 32GB would require a different file system, such as NTFS, to be recognized by these operating systems.

Hibernate consumes the least amount of power among the given options. When a computer is in hibernate mode, it saves the current state of the system to the hard drive and completely shuts down. It does not require any power to maintain the system's state, as opposed to sleep, suspend, and standby modes where the system remains partially active and consumes some power. Hibernate allows for quick startup and resume by restoring the saved state from the hard drive, while consuming minimal power during the hibernation period.

The most likely cause for the computer powering off after ten minutes is that the heat sink is not installed correctly. The heat sink plays a crucial role in dissipating heat generated by the CPU. If it is not installed properly, the CPU can overheat, triggering a thermal protection mechanism that shuts down the computer to prevent damage. This issue can lead to frequent shutdowns and is a common problem when replacing a CPU.

The FDD (Floppy Disk Drive) has the least amount of storage capacity compared to the other options. Floppy disks typically have a storage capacity of 1.44 MB, which is significantly lower than the storage capacities of tape drives, Blu-Ray discs, and SSDs. Tape drives can store several terabytes of data, Blu-Ray discs can store up to 50 GB or more, and SSDs can have storage capacities ranging from a few hundred gigabytes to several terabytes. Therefore, the FDD has the least amount of storage capacity among the given options.

A heat sink is a device that is used to dissipate heat from a component by increasing its surface area. It is typically made of a metal with high thermal conductivity, such as aluminum or copper. Heat sinks work through a process called conduction, where the heat generated by the component is transferred to the heat sink and then dissipated into the surrounding air. Unlike other options listed, such as a liquid cooling system or a case fan, a heat sink does not require any moving parts to dissipate heat, making it a more reliable and low-maintenance solution.

A screwdriver with a magnetized tip should be used to retrieve the screw because the magnetized tip will attract and hold onto the metal screw, making it easier to retrieve from the case of the desktop computer.

After completing an upgrade to a customer's system, the technician should follow up with the customer in a few days. This is important to ensure that the upgrade was successful and that the customer is not facing any problems or issues. By reaching out to the customer, the technician can address any concerns or difficulties that may have arisen after the upgrade and provide any necessary support or assistance. This proactive approach demonstrates good customer service and helps to ensure customer satisfaction.

Windows Vista Business 64-bit requires a minimum of 20GB of hard drive space. Among the given options, the only hard drive that meets this requirement is the 40GBHDD with 15GB of free space.

DRAM (Dynamic Random Access Memory) is a type of memory that can be easily replaced by the user in a computer system. It is a volatile memory that stores data and instructions temporarily while the computer is running. Unlike ROM (Read-Only Memory), which is non-volatile and cannot be easily replaced by the user, DRAM can be easily removed and replaced if needed. SRAM (Static Random Access Memory) and CMOS (Complementary Metal-Oxide-Semiconductor) are also types of memory, but they are not typically user replaceable in a computer system.

XGA (Extended Graphics Array) would be the best resolution setting for an application that requires a minimum resolution of 1024x768. XGA provides a higher resolution than SVGA, PAL, and VGA, making it the most suitable option for meeting the minimum requirement.

AAC (Advanced Audio Coding) and WMA (Windows Media Audio) are both digital audio-only formats. They are commonly used for compressing and encoding audio files while maintaining high sound quality. AAC is widely used in various devices and platforms, including Apple's iTunes and iPod, while WMA is primarily used in Windows-based systems. Both formats support audio playback and are not designed for video or multimedia purposes. Therefore, AAC and WMA are the correct answers as they are the only options that consist of digital audio-only formats.
