CompTIA 220-1201 Online Questions & Answers

• Question 261:

  Which of the following is the most likely cause?

  

  A. The subnet mask Is Incorrect.
  B. NetBIOS is enabled.
  C. DHCP is enabled.
  D. DNS servers are manually set.
  D. DNS servers are manually set.

  ---

  Explanation

  The key detail in the ipconfig output is that the system is receiving an IP address, subnet mask, default gateway, and DHCP server information via DHCP , but the DNS servers shown are 8.8.8.8 and 8.8.4.4 , which are Google's public DNS servers. In most corporate networks, DNS is provided internally by the DHCP server-- usually the same device assigning the IP address. When DNS values are different from DHCP-provided defaults, it indicates manual DNS configuration.

  CompTIA A+ emphasizes that mismatched DNS settings can cause browsing issues, name-resolution delays, or an inability to access internal resources. DNS is critical because it translates domain names into IP addresses; if manually configured, the device bypasses the organization's DNS server and may not resolve internal hostnames.

  The subnet mask is correct for a Class B private network subdivided using /24 (255.255.255.0). NetBIOS being enabled is common and not a cause of connectivity issues here. DHCP being enabled is normal and functioning correctly, as shown by the proper IP lease obtained.

  Thus, the anomalous and most likely problematic configuration is manually configured DNS , making Option D correct.

• Question 263:

  Users have been reporting slow network traffic in a branch office, and the technician needs to determine if packet loss is occurring on the network.

  Which of the following would the technician most likely use to passively assess the network traffic issue?

  A. Cable tester
  B. Network tap
  C. Wi-Fi analyzer
  D. Toner probe
  B. Network tap

  ---

  Explanation

  A network tap (Test Access Point) is a device used for monitoring network traffic. It allows the technician to passively observe the traffic between two network nodes in real-time without introducing latency or affecting the network's performance. By using a network tap, the technician can analyze the data packets flowing through the network to identify if packet loss is occurring, which could be contributing to the slow network traffic in the branch office.

  References:

  Network taps are widely recognized in the field of network troubleshooting and monitoring for their ability to provide a mirror of the traffic that can be analyzed for issues such as packet loss.

• Question 264:

  A technician was called to check an unexpected clicking noise on a desktop that has become more frequent every time a video editing application is loaded. The system fans have been replaced, but the clicking noise remains. Diagnostics have been run on the video card.

  Which of the following should me the technician do FIRST?

  A. Replace the hard drive.
  B. Replace the video card.
  C. Do a System Restore.
  D. Perform a full data backup.
  E. Scan the system for viruses.
  D. Perform a full data backup.

• Question 265:

  Users working with large files back up the files to external hard drives. One user's files take longer to back up than other users' files. The user has tried backing up the files to other users' drives with the same results.

  Which of the following steps should the technician take first to correct this issue?

  A. Replace the hard drive's USB cable.
  B. Defragment the user's external hard drive.
  C. Update the storage drivers on the user's system.
  D. Instruct the user to compress the files.
  B. Defragment the user's external hard drive.

  ---

  Explanation

  If a hard drive is heavily fragmented, file read/write operations can take significantly longer, causing slow backup speeds. Defragmenting the drive organizes the data for more efficient access.

  Why Not A (Replace the hard drive's USB cable): A faulty cable would typically cause disconnections or errors, not just slower speeds.

  Why Not C (Update the storage drivers): This might help if the issue is with system drivers, but the described symptoms point to a fragmentation issue.

  Why Not D (Compress the files): Compression reduces file size but does not address the root cause of the slow backups.

• Question 266:

  A user reports that a network printer has frequent paper jams. The technician examines the printer and finds no obvious obstructions or foreign objects in the paper path.

  Which of the following should the technician do to resolve the issue?

  A. Check for firmware updates specific to the printer model
  B. Inspect and replace the printer rollers
  C. Reseat the fuser assembly
  D. Clean the printer ' s corona wire
  B. Inspect and replace the printer rollers

  ---

  Explanation

  The correct answer is B. Inspect and replace the printer rollers.

  According to CompTIA A+ Core 1 220-1201 objectives under Printers:

  Frequent paper jams with no visible obstruction are often caused by worn or dirty feed rollers, which fail to grip and feed paper properly.

  Inspecting and replacing the rollers ensures smooth paper feeding and prevents repeated jams, particularly in high-use network printers.

  Why the other options are incorrect:

  A. Check for firmware updates: Firmware updates address software or functionality issues, not mechanical paper feeding problems.

  C. Reseat the fuser assembly: Fuser issues typically cause smudging or incomplete toner adhesion, not paper jams.

  D. Clean the corona wire: The corona wire affects toner adhesion and print quality, not paper feeding.

• Question 267:

  Which of the following protocols is used for sending emails?

  A. POP3
  B. IMAP
  C. LDAP
  D. SMTP
  D. SMTP

  ---

  Explanation

  The correct answer is D. SMTP (Simple Mail Transfer Protocol).

  According to CompTIA A+ Core 1 220-1201 objectives under Networking: SMTP is the standard protocol used to send emails from a client to a mail server or between servers.

  POP3 (Post Office Protocol 3) and IMAP (Internet Message Access Protocol) are used for receiving emails, not sending them.

  LDAP (Lightweight Directory Access Protocol) is used for accessing and managing directory services, such as authentication and organizational information, not for email transport.

• Question 268:

  A technician has noticed that a monitored server is receiving a disk failure notice during startup. When the technician clicks to continue, the machine still seems to startup into Windows but at a much slower speed. The technician looks at the BIOS information and sees the machine utilizes a RAID 5 configuration.

  Which of the following does the technician MOST likely need to perform?

  A. Reinstall the HDD drivers.
  B. Rebuild The RAID.
  C. Replace the failed drivers.
  D. Restart the system.
  B. Rebuild The RAID.

  ---

  Explanation

  The disk failure notice during startup indicates that one or more disks in the RAID array have failed. The machine still seems to startup into Windows but at a much slower speed because the RAID 5 configuration can tolerate one disk failure and still operate, but with reduced performance and reliability. The technician most likely needs to rebuild the RAID, which means replacing the failed disk(s) and restoring the data from the parity information. Reinstalling the HDD drivers will not fix the disk failure. Replacing the failed drivers is not a valid option, as drivers are software, not hardware. Restarting the system will not fix the disk failure either.

• Question 269:

  Which of the following virtualization concepts is suitable for a development team that requires a bare minimum platform to run web applications with the capability to dispose and redeploy as needed?

  A. Containers
  B. IaaS
  C. SaaS
  D. Desktop virtualization
  A. Containers

  ---

  Explanation

  The correct answer is A. Containers.

  According to CompTIA A+ Core 1 220-1201 objectives under Networking and Cloud/Virtualization Concepts:

  Containers provide lightweight, portable environments that package applications and their dependencies, allowing them to run consistently across multiple environments.

  Containers are ideal for development teams because they require minimal underlying infrastructure, can be quickly deployed or destroyed, and isolate applications from the host system, making it easier to manage multiple applications simultaneously.

  Why the other options are incorrect:

  B. IaaS (Infrastructure as a Service): Provides virtualized hardware over the cloud but is more general-purpose; it includes virtual machines, storage, and networking, not minimal isolated application environments.

  C. SaaS (Software as a Service): Provides fully managed software to end-users; not intended for deploying custom web applications by a development team.

  D. Desktop virtualization: Provides virtual desktop environments to users; it does not provide a minimal, disposable platform for web application development.

• Question 270:

  A technician is working on a RAID 1 array that is apparently degraded. The technician verifies the RAM and power are both operating as expected.

  Which of the following can the technician do to further isolate the issue?

  A. Perform individual drive diagnostics.
  B. Run the chkdsk /i command.
  C. Rebuild the RAID array.
  D. Reconfigure the array as RAID 0.
  A. Perform individual drive diagnostics.

  ---

  Explanation

  A degraded RAID 1array usually means one of the drives has failed or is failing. The correct next step is to run diagnostics on each drive to identify the faulty one. RAID 1 uses mirroring, so one good drive should still contain all the data.

  Option B:chkdsk checks file system integrity, not hardware drive health.

  Option C:Rebuilding should only occur after identifying and replacing a faulty drive.

  Option D:RAID 0 offers no redundancy and would destroy data in this context.
