  Explanation

  802.1X is a network authentication protocol commonly used in enterprise environments. If the user cannot connect to the office wireless network but can connect at home, the issue is likely related to the 802.1X certificate required for authentication. Installing or updating the certificate will resolve the issue.

  Why Not B (Check the wireless router settings): If other users can connect to the network, this step is unnecessary.

  Why Not C (Update the wireless driver): Driver updates might resolve connectivity issues but are unrelated to 802.1X certificate authentication.

  Why Not D (Disable the Windows firewall): The firewall does not affect 802.1X authentication.

• Question 896:

  A technician receives a call from a user about a new USB 3.1 docking station. The user claims that their laptop does not charge when connected to the dock. The user confirms that the AC adapter for the dock is plugged in.

  Which of the following is the most likely cause?

  A. The dock is not designed to provide power passthrough.
  B. The dock is only connected to a USB 3.0 port.
  C. Proper drivers for the dock were not installed.
  D. Too many accessories are plugged into the dock.
  A. The dock is not designed to provide power passthrough.

  ---

  Explanation

  If a laptop does not charge when connected to a USB 3.1 docking station despite the AC adapter being plugged in, the most likely reason is that the dock is not designed to provide power passthrough. This means that the dock's primary function is connectivity for peripherals rather than power delivery to the laptop. The other options are possible but less likely if the sole issue is the absence of charging functionality when the dock and its power supply are properly connected.

• Question 897:

  Which of the following scenarios best illustrate a need for VDI? (Select two).

  A. An IT engineer who is designing and showcasing organization user experiences for multiple clients
  B. A company that needs to store IOPB worth of data
  C. A manufacturing plant that has high turnover
  D. A bank that has security concerns regarding employee activity
  E. A payment processor that is planning on implementing virtual currency
  F. An application developer who needs to configure network settings for an application
  A. An IT engineer who is designing and showcasing organization user experiences for multiple clients
  D. A bank that has security concerns regarding employee activity

  ---

  Explanation

  The scenarios that best illustrate a need for VDI are A and

  D. VDI can provide several benefits for different use cases, such as: Enhancing security and compliance by centralizing and encrypting data and applications on the server, rather than on the endpoint devices. This can prevent data loss, theft, or leakage, as well as reduce the risk of malware or unauthorized access. This is especially important for organizations that deal with sensitive or regulated information, such as banks, healthcare providers, or government agencies123. Improving flexibility and mobility by allowing users to access their desktops and applications from any device, location, or network. This can enable remote work, bring your own device (BYOD) policies, or disaster recovery scenarios. This is especially useful for organizations that have distributed or mobile workforce, such as IT engineers, consultants, or sales representatives123. Reducing costs and complexity by simplifying the management and maintenance of desktops and applications. This can lower the hardware, software, and energy expenses, as well as the IT staff workload. This is especially beneficial for organizations that have large or diverse desktop environments, such as schools, call centers, or manufacturing plants123. Based on these benefits, the scenarios that best illustrate a need for VDI are:

  A. An IT engineer who is designing and showcasing organization user experiences for multiple clients. This scenario requires flexibility and mobility, as the IT engineer needs to access different desktop environments and applications from various devices and locations. VDI can enable the IT engineer to create and switch between multiple virtual desktops on the same server, and to access them from any client device with an internet connection1.

  D. A bank that has security concerns regarding employee activity. This scenario requires security and compliance, as the bank needs to protect its data and applications from internal and external threats. VDI can enhance the security of the bank's desktop environment by storing and encrypting all data and applications on the server, rather than on the endpoint devices. VDI can also provide granular control and monitoring of user access and activity2. The scenarios that do not illustrate a need for VDI are:

  B. A company that needs to store IOPB worth of data. This scenario does not require VDI, as VDI is not a storage solution but a desktop virtualization solution. VDI can help reduce the storage requirements of endpoint devices by storing data on the server, but it does not provide storage capacity or performance for large- scale data processing or analysis. The company may need a different type of cloud service, such as storage as a service (SaaS) or big data as a service (BDaaS), to store and manage its massive amount of data4.

  C. A manufacturing plant that has high turnover. This scenario does not require VDI, as VDI is not a human resource solution but a desktop virtualization solution. VDI can help reduce the costs and complexity of managing desktops and applications for a large number of users, but it does not address the root causes of high turnover, such as low wages, poor working conditions, or lack of training. The manufacturing plant may need to improve its human resource policies and practices to retain its employees.

  E. A payment processor that is planning on implementing virtual currency. This scenario does not require VDI, as VDI is not a payment solution but a desktop virtualization solution. VDI can help improve the security and flexibility of accessing desktops and applications over the internet, but it does not provide the functionality or compatibility for processing virtual currency transactions. The payment processor may need a different type of cloud service, such as blockchain as a service (BaaS) or cryptocurrency as a service (CaaS), to implement and manage its virtual currency platform.

  F. An application developer who needs to configure network settings for an application. This scenario does not require VDI, as VDI is not a development solution but a desktop virtualization solution. VDI can help provide different desktop environments and applications for testing purposes, but it does not provide the tools or resources for developing or configuring applications. The application developer may need a different type of cloud service, such as platform as a service (PaaS) or software development as a service (SDaaS), to create and deploy applications.

• Question 900:

  A technician receives a phone call from a traveling sales representative indicating that the maps application on a phone is not working. The representative runs a speed test on the phone and gets ~10Mbps in both directions. Which of the following settings should the technician check first to troubleshoot the issue?

  A. Airplane mode
  B. PRL
  C. GPS
  D. LTE
  C. GPS

  ---

  Explanation

  GPS (Global Positioning System) is a feature that allows a phone to determine its location by receiving signals from satellites. A maps application relies on GPS to provide accurate directions and navigation. If GPS is turned off or not working properly, the maps application may not function as expected. The other options are not relevant to the issue. Airplane mode is a setting that disables all wireless communication on a phone, including cellular, Wi-Fi, Bluetooth, and GPS. However, since the representative runs a speed test and gets ~10Mbps in both directions, it means that airplane mode is not enabled. PRL (Preferred Roaming List) is a database that contains information about the cellular towers and networks that a phone can connect to. Updating the PRL can improve the phone's signal strength and coverage, but it does not affect the maps application. LTE (Long Term Evolution) is a standard for high-speed wireless communication on mobile devices. It is related to the cellular data speed and quality, but not to the maps application. To troubleshoot the issue, the technician should check the GPS settings on the phone and make sure that it is turned on and has a clear view of the sky. The technician should also verify that the maps application has permission to access the GPS location. If the problem persists, the technician may suggest resetting the network settings, updating the phone's software, or contacting the maps application's support team.
