   A customer reports that the default local USB printer is no longer working. The technician views the printer properties in the OS and sees the printer is connected to LPT1. Which of the following steps should the technician most likely take next?

   • ATest the printer on a known-good PC.
   • BClear the print queue.
   • CConfigure a different printing port.
   • DSwap the USB and power cables.

   Show answer

   Answer: C

   Explanation

   Explanation: LPT1 Connection: If the printer is listed as connected to LPT1, it suggests that the system is trying to use a parallel (LPT) port for a USB printer, which is not correct. This misconfiguration can cause the printer to appear as not working. Next Steps: Changing the printer's port settings to a USB port (such as USB001 or similar) in the printer properties would be the appropriate step to ensure the printer can communicate correctly with the computer.

   A human resources department uses a network shared with other departments to produce a variety of printed resources for legal retention. The human resources department only wants its members to have access to these materials. Which of the following should the technician implement?

   • ASecurity groups
   • BAudit logs
   • CTime-of-day access
   • DPrint server

   Show answer

   Answer: A

   Explanation

   A. Security groups Security groups allow you to control access to resources by assigning permissions to specific groups of users. This way, only members of the human resources department will have access to the materials.

   A user acquired a new workstation and is attempting to open multiple large Excel files simultaneously. The user is not experiencing the expected performance when executing such large requests. Which of the following should a technician do FIRST?

   • AIncrease the swap partition.
   • BUpgrade the CPU in the workstation.
   • CUpgrade the power supply in the workstation.
   • DUpgrade the RAM in the workstation.

   Show answer

   Answer: A

   Explanation

   No this one does make sense, I think. Because they’re asking what you should do FIRST. So it would make sense to try increasing the swap partition before you go in and start replacing hardware.

   Which of the following utilizes TCP ports 20/21 and transfers data in cleartext?

   • ASNMP
   • BSSH
   • CFTP
   • DTelnet

   Show answer

   Answer: C

   Explanation

   C. FTP. File Transfer Protocol (FTP) is a commonly used protocol for transferring files over the internet. FTP uses TCP ports 20 and 21 to transfer data. However, FTP transfers data in cleartext, which means that the data can be read by anyone who intercepts the transmission. This can be a security concern, as sensitive information such as login credentials and file contents can be easily compromised. For this reason, it is recommended to use more secure protocols, such as Secure File Transfer Protocol (SFTP) or HTTPS, when transferring sensitive data. Simple Network Management Protocol (SNMP) uses UDP ports 161 and 162 and transfers data in cleartext, whereas Secure Shell (SSH) uses TCP port 22 and transfers data securely. Telnet also uses TCP port 23 and transfers data in cleartext.

7. Question 587 · 624 in bank

   An organization is looking to upgrade the processing ability for its computers. Most users report that whenever multiple applications are being utilized, the system's response time slows down drastically. When only one application is open, the response time is acceptable. Which of the following should be upgraded FIRST?

   • ASSD
   • BCPU
   • CHDD
   • DRAM

   Show answer

   Answer: D

   Explanation

   Random Access Memory (RAM) is a type of memory that temporarily stores data for the processor to access. If the system's response time slows down when multiple applications are being utilized, it is likely that the amount of RAM available is insufficient to handle the demand. Upgrading the RAM can help increase the processing ability of the computers and improve the system's performance when multiple applications are being used. Adding or upgrading a Solid-State Drive (SSD) can also improve performance, but it is unlikely to resolve the issue with slow response times when multiple applications are being used. Upgrading the Central Processing Unit (CPU) may also help, but it is often more expensive than upgrading the RAM. Upgrading the Hard Disk Drive (HDD) is not likely to have a significant impact on the system's performance when multiple applications are being utilized.

   Client-side virtualization guest machines have security requirements similar to physical machines, but they also need to ensure separation from other guest machines. Which of the following BEST describes this client-side guest security requirement?

   • AIsolation
   • BAuthentication
   • CHardening
   • DAuthorization

   Show answer

   Answer: A

   Explanation

   Virtual networks require the same attention to security details as physical networks. Because a single physical computer can house two or more VMs, knowing which computers in an organization are using VMs is a vital first step in securing a virtualized environment. Security: A VMM that enables sandboxing (isolation) of each VM and that provides physical partitioning of resources provides better security against attacks. https://www.pearsonitcertification.com/articles/article.aspx?p=3150818&seqNum=4

10. Question 590 · 624 in bank

    Recently, an organization received a number of spam emails that passed through the spam gateway. These emails contained generally the same information, but the sending domains were different. Which of the following solutions would BEST help mitigate the issue?

    • AUpdating the keyword filtering
    • BEditing the sender policy framework
    • CContacting the gateway vendor
    • DVerifying DMARC is enabled

    Show answer

    Answer: A

    Explanation

    DMARC is used to prevent an organizations "outgoing" email from being marked as spam. The question explains that the spam is incoming and DMARC would do nothing to help the organization from receiving spam from different domains. Keywords are mostly the same with these incoming spam messages. Update your keywords and be done with it. Those of you who believe DMARC is the answer, please spend 20 or more minutes researching it and how it works. It is used to prevent spoofing and phishing of your own organizations email.
