  Explanation

  To configure a printer for network communications, the technician must configure its network settings, such as gateway, subnet mask, and IP address. The gateway is the IP address of the router or device that connects the printer to other networks or the internet. The subnet mask is a value that defines which part of the IP address identifies the network and which part identifies the host or device on that network. The IP address is a unique identifier that allows the printer to communicate with other devices.

• Question 883:

  Which of the following video cables can carry an audio signal?

  A. HDMI
  B. S-Video
  C. VGA
  D. DVI
  A. HDMI

  ---

  Explanation

  This is because HDMI (High-Definition Multimedia Interface) is a digital video cable that can also carry audio signals1. HDMI cables are commonly used to connect devices like Blu-ray players, game consoles, and streaming boxes to HDTVs and monitors. The other options are not capable of carrying audio signals. VGA (Video Graphics Array) is an analog video cable that only carries RGBHV signals12. S-Video (Super Video) is another analog video cable that carries separate luminance and chrominance signals1 . DVI (Digital Visual Interface) is a digital video cable that can carry either analog or digital signals, but not audio1.

• Question 884:

  A systems administrator is configuring a server to host several virtual machines. The administrator configures the server and is ready to begin provisioning the virtual machines.

• Question 885:

  An engineer is setting up two-factor authentication so users can access a company's human resources system. Which of the following should the engineer require users to do?

  A. Use a mobile authenticator application.
  B. Connect to the company's Wi-Fi.
  C. Connect through the VPN.
  D. Use a bastion server.
  A. Use a mobile authenticator application.

  ---

  Explanation

  Two-factor authentication (2FA) is a method of verifying a user's identity by requiring two pieces of evidence: something the user knows (such as a password) and something the user has (such as a device). A mobile authenticator application is a software program that runs on a smartphone or tablet and generates a one-time code or token that the user can enter along with their password to access a system. This adds an extra layer of security to prevent unauthorized access.

• Question 886:

  A technician wants to monitor network statistics for devices communicating with one another on the local subnet.

  Which of the following devices should the technician install?

  A. Managed switch
  B. Router
  C. Access point
  D. Firewall
  A. Managed switch

  ---

  Explanation

  A managed switch provides advanced features such as traffic monitoring and VLAN configuration, allowing a technician to view network statistics for devices on the local subnet.

  Why Not B (Router): A router connects different networks and directs traffic between them but does not provide detailed subnet-level statistics.

  Why Not C (Access point): Access points provide wireless connectivity but lack traffic monitoring features.

  Why Not D (Firewall): A firewall filters traffic but is not used for monitoring detailed statistics on a local subnet.

  Core 1 (220-1101), Section 2.6, network monitoring tools.

  Explanation

• Question 890:

  Which of the following is an advantage that OLED displays have over LCD displays?

  A. The color does not degrade over time.
  B. The power consumption is lower.
  C. The power contrast results in finer grayscale levels.
  D. A backlight is utilized.
  B. The power consumption is lower.

  ---

  Explanation

  OLED (Organic Light Emitting Diode) displays have lower power consumption than LCD (Liquid Crystal Display) displays because they do not require a backlight to produce light. Each pixel in an OLED display can emit its own light, which also allows for higher contrast and finer grayscale levels. However, OLED displays are more prone to color degradation over time than LCD displays, which use filters to create colors. Verified
