QUESTION 97 A technician is setting up a new laptop for a user who wants to be able to quickly pack up the laptop and leave if needed. The user has the following accessories: USB badge reader USB badge printer USB signature pad 3.5mm headset HDMI external monitor IT Certification Exams - Questions & Answers | Vdumps.com Mouse Which of the following is the best way to meet the user's requirement? A. Directly connect all accessories to the laptop. B. Provide the user with a second laptop. C. Connect everything to a compatible docking station. D. Provide the user with a USB hub. Correct Answer: C Section: Explanation: The best way to meet the user's requirement is C. Connect everything to a compatible docking station. A docking station is a device that allows a laptop to connect to multiple peripherals and accessories with a single connection. A docking station usually has ports for USB, HDMI, audio, Ethernet, and power, as well as slots for expansion cards. A docking station can enhance the functionality and convenience of a laptop by providing a desktop-like experience1. A compatible docking station is one that matches the laptop's model, brand, and connector type2. A port replicator is a simpler device that only replicates the ports of the laptop, such as USB and HDMI, without providing additional features or power. A port replicator can also allow a laptop to connect to multiple peripherals and accessories with a single connection, but it does not offer the same benefits as a docking station1. Directly connecting all accessories to the laptop would not meet the user's requirement, as it would be cumbersome and time-consuming to pack up and leave if needed. The user would have to disconnect and reconnect multiple cables every time they want to use or move the laptop. This option would also limit the number of accessories that can be connected, as the laptop may not have enough ports for all of them. Providing the user with a second laptop would not meet the user's requirement, as it would be expensive and impractical. The user would have to transfer data and settings between the two laptops, and keep them both updated and secure. This option would also create confusion and redundancy, as the user would have two identical devices. Providing the user with a USB hub would not meet the user's requirement, as it would only allow the user to connect more USB devices to the laptop. A USB hub is a device that splits one USB port into multiple ports, but it does not support other types of connections, such as HDMI or audio. A USB hub would also require an external power source or drain the laptop's battery faster. This option would not help the user connect the HDMI external monitor or the 3.5mm headset. QUESTION 98 Which of the following cloud models allows an organization to retain data on site as well as in the cloud? A. Public B. Community C. Hybrid D. Private Correct Answer: C Section: Explanation: The correct answer is C. Hybrid. A hybrid cloud model is a combination of two or more different cloud models, such as public, private, community, or on-premises. A hybrid cloud model allows an organization to retain data on site as well as in the cloud, depending on the security and performance requirements of the data. A hybrid cloud model can also provide flexibility, scalability, and cost-efficiency for the organization12. A public cloud model is a cloud service that is available to anyone over the internet. A public cloud model does not allow an organization to retain data on site, as the data is stored and managed by a third-party provider. A public cloud model can offer lower costs, higher availability, and easier access, but it may have less security and control over the data12. A community cloud model is a cloud service that is shared by a group of organizations that have similar needs or goals. A community cloud model does not allow an organization to retain data on site, as the data is stored and managed by a third-party provider or one of the participating organizations. A community cloud model can offer higher security, privacy, and compliance, but it may have higher costs and lower availability than a public cloud model12. A private cloud model is a cloud service that is exclusively used by a single organization. A private cloud model can allow an organization to retain data on site or in the cloud, depending on the configuration of the private cloud. A private cloud model can offer higher security, control, and customization, but it may have higher costs and lower scalability than a public cloud model12. QUESTION 99 Isolating email attachments in a safe place until the attachments can be scanned for malware is defined as: IT Certification Exams - Questions & Answers | Vdumps.com A. an approve listing. B. a screened subnet. C. cross-platform virtualization. D. sandboxing. Correct Answer: D Section: Explanation: The correct answer is D. Sandboxing. Sandboxing is a security technique that isolates email attachments in a safe place until the attachments can be scanned for malware. A sandbox is a virtual environment that mimics the operating system and applications of the user, but prevents any changes or damage to the actual system. A sandbox can also monitor the behavior and activity of the attachments and detect any malicious code or actions12. An approve listing is a security technique that allows only trusted or authorized email senders or domains to be received by the user. An approve listing can help reduce spam and phishing emails, but it does not scan or isolate email attachments for malware3. A screened subnet is a security technique that creates a buffer zone between the internal network and the internet. A screened subnet uses firewalls and routers to filter and control the traffic that enters and exits the network. A screened subnet can help protect the network from external attacks, but it does not scan or isolate email attachments for malware. Cross-platform virtualization is a technology that allows running multiple operating systems and applications on the same physical machine. Cross-platform virtualization can help improve efficiency, flexibility, and compatibility, but it does not scan or isolate email attachments for malware. QUESTION 100 A user calls the help desk about a 4K monitor that will not output an image from a desktop. The monitor was working previously but now shows a black screen with a message stating a signal is not detected. The desktop is connected via HDMI, and the monitor has an empty DVI port. Which of the following steps should the technician perform first? (Select two). A. Check the version of the HDMI cable. B. Check the input source. C. Set up the desktop for DVI. D. Replace the HDMI cable. E. Install OS updates. F. Initiate a system restore. Correct Answer: A, B Section: Explanation: The first steps that the technician should perform are A. Check the version of the HDMI cable and B. Check the input source. A possible cause of the problem is that the HDMI cable is not compatible with the 4K resolution of the monitor. HDMI cables have different versions that support different features and bandwidths. For example, HDMI 1.4 supports up to 4K at 30 Hz, while HDMI 2.0 supports up to 4K at 60 Hz1. The technician should check the version of the HDMI cable and make sure it matches the specifications of the monitor and the desktop. Another possible cause of the problem is that the monitor is not set to the correct input source. The input source is the option that allows the monitor to switch between different video signals from different ports, such as HDMI, DVI, VGA, or DisplayPort2. The technician should check the input source and make sure it is set to HDMI, since that is how the desktop is connected to the monitor. The input source can usually be changed using the buttons or menu on the monitor itself2. QUESTION 101 A technician installed a Cat 5 UTP cable approximately 275ft (84m) from a network switch in an office to a workstation located on a factory floor. The technician sees both a flashing green LED and a flashing orange LED on the workstation's NIC. Which of the following should the technician do first? A. Check for loose connections, pinched bends, and physical damage. B. Install a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run. IT Certification Exams - Questions & Answers | Vdumps.com C. Replace the entire run of Cat 5 UTP cable with Cat 5 STP cable. D. Upgrade the entire cable run to multimode fiber. Correct Answer: B Section: Explanation: The correct answer is B. Install a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run. The problem is most likely caused by the excessive length of the Cat 5 UTP cable, which exceeds the maximum limit of 100 meters (328 feet) for Ethernet over twisted pair12. This can result in signal degradation, interference, and packet loss, which can affect the network performance and connectivity. The flashing green LED indicates that the NIC is receiving data, while the flashing orange LED indicates that the NIC is sending data3. However, these LEDs do not indicate the quality or speed of the data transmission, which may be poor due to the long cable run. The best solution is to install a powered hub as close as possible to the halfway point in the Cat 5 UTP cable run. A powered hub is a device that can amplify and regenerate the signal, as well as provide additional ports for connecting more devices. A powered hub can extend the effective range of the cable and improve the network performance and connectivity1. The other options are not the best solutions for this problem. Checking for loose connections, pinched bends, and physical damage is a good troubleshooting step, but it is unlikely to solve the problem if the cable is too long. Replacing the entire run of Cat 5 UTP cable with Cat 5 STP cable may reduce some interference, but it will not solve the problem of signal degradation due to the length. Upgrading the entire cable run to multimode fiber may provide better performance and range, but it will also re
