   After a heavily used color laser printer was serviced to remove excessive dust, the image quality decreased. Which of the following should a technician most likely check on the printer?

   • AToner
   • BCalibration
   • CFuser
   • DDrum

   Show answer

   Answer: D

   Explanation

   Reasoning for the Answer: Drum (D) Reasoning: Dust Accumulation: The drum is a critical component in a laser printer, responsible for transferring toner onto the paper. When a printer is heavily used, dust can accumulate on the drum's surface. This dust can interfere with the toner transfer process, leading to uneven or faded prints. Service and Dust Removal: After a service to remove excessive dust, it's highly likely that some dust particles may have remained on the drum, even after the cleaning process. These residual particles can still impact the printer's performance. Drum Sensitivity: Drums are sensitive components and can be easily damaged or contaminated. Even small amounts of dust or debris can affect their functionality.

   Which of the following technologies can allow multiple networks to traverse a switch?

   • AVLAN
   • BVRRP
   • CVPN
   • DDHCP

   Show answer

   Answer: A

   Explanation

   Virtual Local Area Networks (VLANs) separate an existing physical network into multiple logical networks. Thus, each VLAN creates its own broadcast domain. Communication between two VLANs can only occur through a router that is connected to both. VLANs work as though they are created using independent switches.

   Which of the following cables provides the best performance with the least EMI?

   • ACat 5
   • BCat 6
   • CCat 7
   • DCoaxial

   Show answer

   Answer: D

   Explanation

   While Cat 7 cables offer advanced shielding, other Cat cables also have varying levels of shielding. For example, Cat 5e and Cat 6 cables can be shielded or unshielded. Shielded cables are more resistant to interference but are also more expensive and difficult to install. In general, Cat 7 cables offer the best combination of performance and interference protection, making them ideal for high-performance networks where signal integrity is critical. However, for most home and small office networks, Cat 6 or Cat 6a cables are sufficient. GG

6. Question 516 · 624 in bank

   A user is having difficulty connecting to the corporate Wi-Fi network. The user has the correct SSID and network key, but the connection fails every time the user attempts to connect. Which of the following is the most likely cause of the issue?

   • AIncorrect security settings
   • BOutdated firmware
   • CInsufficient power input to the AP
   • DRouter malfunction

   Show answer

   Answer: A

   Explanation

   Given that the user has the correct SSID and network key but still fails to connect, the most likely cause of the issue is incorrect security settings. This could include using the wrong encryption method (e.g., WPA instead of WPA2), wrong authentication type (e.g., using WEP instead of WPA2-PSK), or mismatched security settings between the client device and the Wi-Fi access point. Therefore, the correct answer is: A. Incorrect security settings

   A user returns to work after a two-week vacation and cannot connect to an internal server. The remote drives were working the last time the user accessed them. Which of the following steps should the technician take next?

   • AConduct external research on the server software vendor’s website.
   • BReference the server vendor's documentation for guidance.
   • CConfirm a theory and determine the next steps to resolve the issue.
   • DDetermine if any infrastructure changes have been made.

   Show answer

   Answer: D

   Explanation

   Given the situation described, the most appropriate next step for the technician is to determine if any infrastructure changes have been made during the user's absence. Changes in the network or server configuration could potentially affect the user's ability to connect to the internal server. Therefore, the correct answer is: D. Determine if any infrastructure changes have been made.

8. Question 518 · 624 in bank

   A user purchased a retail router and would like to set up a private network. Which of the following network address ranges should the user configure?

   • A170.50.0.0 to 170.50.255.255
   • B172.16.0.0 to 172.31.255.255
   • C224.0.0.0 to 224.255.255.255
   • D239.0.0.0 to 239.255.255.255

   Show answer

   Answer: B

   Explanation

   The user should configure a private network using one of the reserved IP address ranges specified for private use by RFC 1918. These ranges are: 10.0.0.0 to 10.255.255.255 172.16.0.0 to 172.31.255.255 192.168.0.0 to 192.168.255.255 Option B falls within the second range (172.16.0.0 to 172.31.255.255), which is commonly used for private networks. Therefore, the correct answer is: B. 172.16.0.0 to 172.31.255.255

9. Question 519 · 624 in bank

   A user is reporting that a computer has been very slow in recent days. The technician looks into the problem and finds pop-ups are randomly appearing on the screen. Which of the following is the next step the technician must take?

   • AEstablish a knowledge base.
   • BEstablish a theory of probable cause.
   • CEstablish a new theory and consider escalating.
   • DEstablish a plan of action.

   Show answer

   Answer: B

   Explanation

   Given the symptoms described, the next step for the technician should be to establish a theory of probable cause. The sudden appearance of pop-ups and the computer's slow performance could be indicative of malware or potentially unwanted programs (PUPs) running in the background. By identifying this as a possible cause, the technician can then proceed with a plan of action to diagnose and address the issue, which may involve running antivirus or antimalware scans, removing suspicious software, or performing other remediation steps as necessary. Therefore, the correct answer is: B. Establish a theory of probable cause.

10. Question 520 · 624 in bank

    A company wants to add virtual servers to handle unusually high web traffic usage. Which of the following is the most efficient way?

    • ACommunity cloud
    • BFile synchronization
    • CRapid elasticity
    • DCloud VDI

    Show answer

    Answer: C

    Explanation

    The most efficient way for a company to handle unusually high web traffic usage by adding virtual servers is through rapid elasticity. Rapid elasticity is a characteristic of cloud computing that enables resources, such as virtual servers, to be rapidly provisioned and released in response to demand. This allows the company to quickly scale up its server capacity during periods of high traffic and scale it back down when the demand decreases, ensuring efficient resource utilization and cost-effectiveness. Therefore, the correct answer is: C. Rapid elasticity.
