• Question 401:

  Which of the following server types can dynamically assign primary and secondary DNS?

  A. DHCP server
  B. Global catalog server
  C. Web server
  D. Name server
  A. DHCP server

  ---

  Explanation

  A DHCP (Dynamic Host Configuration Protocol) server is a server type that can dynamically assign IP addresses and other network configuration parameters to clients, such as primary and secondary DNS (Domain Name System) servers. DNS servers are responsible for resolving hostnames to IP addresses and vice versa. A global catalog server, a web server, and a name server are not involved in DHCP operations.

• Question 402:

  Which of the following allows a switch to be divided into separate logical networks?

  A. VLAN
  B. SSL VPN
  C. NAT
  D. RADIUS
  A. VLAN

  ---

  Explanation

  A Virtual LAN (VLAN) is a network topology that allows a switch to be divided into separate logical networks. This allows for the creation of multiple broadcast domains within a single physical network, improving network segmentation and security. With VLANs, you can segment your network so that different departments, applications, or users are isolated from each other, improving network security and performance.

• Question 403:

  An engineer is experiencing unexpected reboots on a graphics workstation when rendering complex 3-D models. The workstation is configured with a 115V power supply that is rated at 200W and connected to a UPS. The central processing unit contains 16 hyperthreaded cores, and a discrete graphics solution utilizing an 8-pin power connector is installed in a PCI Express x16 slot. Which of the following indicates where the technician should begin troubleshooting?

  A. The UPS, as 115V is insufficient for the configuration and should be increased to 220V
  B. The power supply, as 200W is insufficient when the GPU is heavily tasked
  C. The graphics card, as it is the component that triggers the unexpected reboots
  D. The motherboard, as only standard PCI slots should be used for high-end graphics cards, not PCI Express slots
  B. The power supply, as 200W is insufficient when the GPU is heavily tasked

  ---

  Explanation

  The unexpected reboots on a graphics workstation when rendering complex 3-D models may be caused by insufficient power supply. The workstation is configured with a 115V power supply that is rated at 200W, which may not be enough when the GPU is heavily tasked. The technician should begin troubleshooting by checking the power supply.

• Question 404:

  A company has a dot matrix printer that uses carbon paper. The company reports that the first page is printing too light, although the following pages are still legible. Which of the following MOST likely needs to be fixed?

  A. The print drum is worn and loose causing the printing to be light in places
  B. The ribbon is low on ink or missing and must be replaced to get proper output
  C. The heating element has failed, and a new one needs to be installed for proper transfer
  D. The wrong type of filement is loaded, preventing it from sticking correctly
  E. The fuser assembly is not calibrated properly, causing it to impact the paper too hard
  B. The ribbon is low on ink or missing and must be replaced to get proper output

  ---

  Explanation

  Dot Matrix printers do not use heat, they use a pin striking an inked ribbon (for the first copy, the subsequent copies are handled by the carbon paper) The ribbon is low on ink or missing and must be replaced to get proper output in a dot matrix printer that uses carbon paper.

• Question 405:

  A user needs to connect a laptop to the internet while traveling on a train. Which of the following features should be enabled on the user's phone?

  A. Bluetooth
  B. Near-field communication
  C. Hotspot
  D. Roaming
  C. Hotspot

  ---

  Explanation

  A hotspot is a feature that allows a phone to share its cellular data connection with other devices via Wi-Fi, Bluetooth, or USB. This can be useful when traveling on a train, where Wi-Fi networks may not be available or reliable. A hotspot can provide internet access to a laptop or other devices that need to connect to the web. Bluetooth is a wireless technology that allows devices to communicate over short distances, usually within 10 meters. It can be used to pair devices such as headphones, speakers, keyboards, mice, etc. However, it cannot be used to share internet access from a phone to a laptop. Near-field communication (NFC) is a wireless technology that allows devices to exchange data by touching or bringing them close together, usually within 4 cm. It can be used for applications such as contactless payments, smart cards, digital tickets, etc. However, it cannot be used to share internet access from a phone to a laptop. Roaming is a feature that allows a phone to use another carrier's network when the home network is not available. This can be useful when traveling abroad, where the home network may not have coverage or agreements with local operators. However, roaming can incur additional charges and may not provide the same speed or quality of service as the home network. Roaming does not affect the ability of the phone to share internet access with other devices via hotspot.

• Question 406:

  Ann, an accountant, reports that after turning on her new laptop, she received a message stating her IP address is already in use on the system. She tried going back to her old desktop, which she now only uses for email, but received the same message. The technician checks the account and sees a comment that Ann requires a special network setup to connect to the banking software. Which of the following should the technician do to resolve the issue?

  A. Remove the static IP configuration from the desktop.
  B. Set the laptop configuration to DHCP to prevent conflicts.
  C. Replace the network card in the laptop, as it may be defective.
  D. Bridge the LAN connection between the laptop and the desktop.
  B. Set the laptop configuration to DHCP to prevent conflicts.

• Question 408:

  A laptop has been returned for a screen repair. The owner insists the screen is broken, but occasionally a faded image is able to be seen in very bright settings on the desktop. Which of the following steps should the repair technician take FIRST?

  A. Replace the graphics card.
  B. Replace the screen, as the customer insists.
  C. Recommend the usage of an external display instead.
  D. Ensure the backlight is functioning as expected.
  D. Ensure the backlight is functioning as expected.

  ---

  Explanation

  If a laptop has been returned for a screen repair and the owner insists the screen is broken, but occasionally a faded image is able to be seen in very bright settings on the desktop, the first step the repair technician should take is to ensure the backlight is functioning as expected. If the backlight is faulty, the screen may appear to be broken, but it may only be dim or too dark to be visible

• Question 409:

  Which of the following network devices is used to separate broadcast domains?

  A. Switch
  B. Wireless access point
  C. Router
  D. Hub
  C. Router

  ---

  Explanation

  A router (option C) is a network device that is used to separate broadcast domains. A broadcast domain is a logical division of a computer network in which all nodes can reach each other by broadcast at the data link layer. Routers operate at the network layer of the OSI model and use routing tables to determine the best path for forwarding packets between different networks. By separating broadcast domains, routers can help to reduce network congestion and improve performance. When a router receives a broadcast packet on one of its interfaces, it does not forward the packet to any other interfaces. This means that only devices within the same broadcast domain as the sender will receive the broadcast packet.

• Question 410:

  A security team wants to implement compliance controls that only permits the installation of company-approved software on user laptops.

  Which of the following should the IT department deploy?

  A. EDR
  B. VPN
  C. MDM
  D. SaaS
  C. MDM

  ---

  Explanation

  Mobile Device Management (MDM) allows IT departments to enforce compliance controls, such as restricting the installation of unapproved software, on laptops and mobile devices.

  Why Not A (EDR): Endpoint Detection and Response focuses on detecting and mitigating security threats, not compliance controls.

  Why Not B (VPN): Virtual Private Networks provide secure connections but do not enforce software installation policies.

  Why Not D (SaaS): Software as a Service refers to software delivery models and does not enforce compliance controls.
