A network administrator must ensure that a printer will still be assigned a specific IP address even if all addresses are depleted.
Which of the following network configuration concepts is this describing?
- A. Reservation
- B. VLAN
- C. Lease
- D. Exclusion
Answer: A
Explanation:
A DHCP reservation binds a specific MAC address to an IP address so the device always receives the same IP from the DHCP server. This ensures network devices like printers maintain consistent connectivity and availability even when the IP pool is low.

A company wants to save printing costs by restricting network printer use. The company implements a solution that requires employees to authenticate to the printer to release print jobs Which of the following has the company implemented?
- A. Access control list
- B. Badging
- C. Print server
- D. Audit logging
Answer: B
Explanation:
Badging is a form of authentication that requires employees to use a badge or ID card to release print jobs. This solution reduces unnecessary printing by ensuring only authorized users print.
Why Not A (Access control list): While ACLs manage permissions, they are not used for physical authentication at printers.
Why Not B (Audit logging): Audit logs track actions but do not restrict printer access.
Why Not D (Print server): A print server manages print jobs but doesn't enforce authentication.
CompTIA A+ Exam Reference: Core 2 (220-1102), Section 2.5, authentication mechanisms.

Which of the following services are typically provided by a networked host to facilitate file sharing across different OSs? (Select two).
- A. LDAP
- B. FTP
- C. ROP
- D. SMB
- E. NTP
- F. IMAP
Answer: B,D
Explanation:
Comprehensive and Detailed Explanation
To enable file sharing across different operating systems, CompTIA A+ emphasizes the use of:
✔ SMB (Server Message Block)
The primary file-sharing protocol used by Windows.
Also supported on macOS and Linux (via Samba).
Allows shared folders, printers, and network browsing.
✔ FTP (File Transfer Protocol)
A cross-platform file transfer service supported by all major OSs.
Commonly used to upload/download files between systems of different types.
These two protocols are explicitly listed in CompTIA objectives under network protocols and file services.
Why the other options are incorrect
A . NTP - Time synchronization, not file sharing.
C . IMAP - Email protocol, not related to file sharing.
E . ROP - Not a file-sharing protocol (Return-Oriented Programming = security exploit).
F . LDAP - Directory service for authentication, not file sharing.

Explanation:
Elasticity in cloud computing refers to the ability of a system to automatically allocate and release resources (such as CPU, RAM, or virtual machines) as workload demands change. This feature is key to ensuring that resources are used efficiently without manual intervention.
NEW QUESTION # 96
A user is unable to connect to network resources. A technician discovers that the user's device has an invalid static IP v dress. Which of the following should the technician configure on the user's device to request an IP address?
- A. DNS
- B. FTP
- C. SSH
- D. DHCP
Answer: D
Explanation:
DHCP (Dynamic Host Configuration Protocol) dynamically assigns IP addresses to devices on a network, resolving the issue of an invalid static IP address. Configuring the device to use DHCP allows it to request and receive a valid IP address automatically.
NEW QUESTION # 97
A company's directory services server is located on premises. Which of the following best describes the directory services infrastructure?
- A. Private cloud
- B. Public cloud
- C. Community cloud
- D. Hybrid cloud
Answer: A
Explanation:
In CompTIA A+ Core 1 (220-1201) cloud concepts, the key differentiator between cloud deployment models is where the service is hosted and who owns/uses the underlying infrastructure. If a company's directory services server (for example, a domain controller providing authentication/authorization and centralized identity management) is located on premises, that points to infrastructure that is owned and operated by the organization for its own internal use. This aligns best with a private cloud model, which is defined as cloud resources dedicated to a single organization and can be implemented on-premises (internally hosted) or in a dedicated off-site environment.
It is not a public cloud because public cloud services are hosted by a third-party provider and shared across multiple customers. It is not hybrid cloud because hybrid requires a mix of on-prem resources and public cloud resources working together (the question only specifies on-prem). It is not community cloud because that involves shared infrastructure among multiple organizations with common needs.
NEW QUESTION # 98
A third-party contractor recently installed a new switch, router, and cabling for a small corporate office. After the installation, users started experiencing issues connecting to resources over the network.
INSTRUCTIONS
Click on each PC and server to review outputs. From the remediation section on the right, select an issue and solution for each device.
Answer:
Explanation:
See the Explanation and detailed steps below.
Explanation:
Looking at the network configurations and outputs from both PCs and servers, here are the possible issues and solutions:
1. PC 1
Issue: The IP address for PC1 is 192.168.1.1, which conflicts with Server 1 (which also uses 192.168.1.1).
Solution: Change the IP address on PC1 to a unique one within the range, like 192.168.1.3.
2. PC 2
Issue: PC 2 is configured with 192.168.1.2, which conflicts with Server 2 that has the same IP address.
Solution: Update the IP address on PC 2 to something unique, like 192.168.1.4.
3. Server 1
Issue: The IP address for Server 1 is 192.168.1.1, which conflicts with PC1.
Solution: Since Server 1 and PC1 are using the same IP address, change one of them. For Server 1, you could change the IP address to 192.168.1.5.
4. Server 2
Issue: Server 2 is using the IP address 192.168.1.2, which conflicts with PC2.
Solution: Update Server 2 to use a different IP address, such as 192.168.1.6.
General Remediation:
The primary problem here is overlapping IP addresses, leading to connectivity issues. Each device on the network must have a unique IP address. After making these changes, ensure that all devices can communicate properly by testing the connection between devices and verifying they can access shared resources.

NEW QUESTION # 102
An engineer must implement a solution to facilitate and maintain an organization's legacy application until it is retired. The application is currently hosted on three physical servers. Which of the following is the most suitable concept for this purpose?
- A. SAN
- B. FaaS
- C. Virtualization
- D. Configuration management platform
Answer: C
Explanation:
Virtualization is the most suitable solution for maintaining a legacy application that is currently running on multiple physical servers. According to CompTIA Core 1 (220-1201) virtualization concepts, virtualization allows physical servers to be consolidated into virtual machines (VMs) that run on a single or reduced number of physical hosts while preserving the original operating systems and application environments.
Legacy applications often rely on older operating systems, specific hardware configurations, or outdated dependencies. Virtualization enables the organization to encapsulate the legacy environment, reducing hardware dependency and simplifying maintenance until the application can be fully retired. This approach also lowers power consumption, hardware costs, and physical space requirements while improving manageability and backup options.
A SAN (Storage Area Network) provides shared storage but does not address application hosting or server consolidation. FaaS (Function as a Service) is a cloud-native, event-driven computing model that requires application redesign and is unsuitable for legacy systems. A configuration management platform is used to manage and automate system configurations but does not replace physical servers or host applications.
CompTIA highlights virtualization as a key strategy for supporting legacy systems, improving flexibility, and extending the lifespan of applications during transition periods.

NEW QUESTION # 103
A technician is troubleshooting a network issue. Users report that the connection keeps dropping and reconnecting every few seconds. The technician:
- Verifies the network configuration settings are correct on the
workstation
- Tests the network cable from the workstation to the switch and finds
no issues
- Uses a known-good workstation on the existing network cable and
replicates the reported issue
Which of the following should the technician do next?
- A. Check the network logs for evidence of port flapping.
- B. Assign a static IP to the impacted workstations.
- C. Add new network hardware to reduce congestion
- D. Validate the environment for external interference.
Answer: A
Explanation:
Since the NIC, cable, and workstation configuration have all been ruled out, and the problem persists even with a known-good PC on the same switch port, this behavior points to an unstable link at the switch itself (often called "port flapping"). Examining the switch's event or syslog will reveal if the port is constantly going up and down, confirming a hardware or configuration issue on the switch side.
NEW QUESTION # 104
A user is testing a new OS that is contained on a USB drive. The user wants the new OS to load automatically when the computer is turned on. Which of the following should the user configure?
- A. Trusted Platform Module
- B. BIOS password
- C. Boot options
- D. USB permissions
Answer: C
Explanation:
To boot from a USB drive, the user must configure the boot order in the system BIOS/UEFI to prioritize the USB device. This setting tells the computer to load the operating system from the USB device on startup.
From CompTIA A+ 220-1101 Official Study Guide, Objective 3.5 - Configure BIOS/UEFI settings:
"The boot order determines the sequence in which the system firmware attempts to find an OS to boot. Setting USB as the first boot device allows the computer to boot from a USB drive." Verified Source:

NEW QUESTION # 105
A student configures a wireless SOHO network to connect four laptops and one multifunction printer. All laptops must have internet access and be able to use the printer. Which of the following settings ensures the printer is always available?
- A. Use dynamic IP addresses from the ISP router for all the devices.
- B. Configure dynamic IPs for the laptops and a static IP for the printer on the same subnet.
- C. Use APIPA for laptops and connect the printer to the ISP router.
- D. Manually assign IP addresses to the laptops and printer based on the public IP from the ISP.
Answer: B
Explanation:
Comprehensive and Detailed Explanation (100-150+ Words):
CompTIA A+ stresses that printers must use static IP addresses to remain consistently reachable on a LAN.
When using DHCP, the printer's IP address may change, causing laptops to lose access. By assigning a static IP within the same subnet, the printer becomes a stable, discoverable network resource for all laptops.
Using dynamic IPs for the laptops is perfectly acceptable in SOHO environments, because clients don't require permanent IPs. Assigning public IPs (Option B) is incorrect and unsafe. APIPA (169.254.x.x) does not route and cannot reach the internet or a standard printer. Using dynamic ISP-assigned IPs for all devices (Option D) is also incorrect because ISP routers typically give only one public IP, not multiple internal ones.
Therefore, to ensure the printer is always reachable, the correct configuration is: DHCP for laptops, static IP for printer a best practice detailed in CompTIA's networking and SOHO setup guidelines.

NEW QUESTION # 108
A technician has built a new computer. On the initial startup, the computer passes POST but will not turn on the operating system. Which of the following components has failed?
- A. Audio card
- B. CPU
- C. HDD
- D. Power supply
Answer: C
Explanation:
When a newly built computer successfully passes POST, it indicates that the CPU, RAM, motherboard, video output, and other essential components are functioning at a hardware level. POST will typically fail or display error codes if there are problems with the CPU, RAM, GPU, or power delivery. Therefore, the fact that POST succeeds allows us to eliminate those components from suspicion.
The issue arises after POST, when the system attempts to load an operating system. For the OS to load, the BIOS/UEFI must detect a working storage device-such as an HDD, SSD, or NVMe drive-containing a bootable OS. If the computer cannot locate or read the drive, the system will halt at a boot error, such as "No boot device found," "Insert boot media," or similar messages. This is consistent with a failed or improperly connected HDD.
A failed HDD prevents access to boot files, even though the rest of the system hardware functions normally.
Audio cards are irrelevant to booting. A failed CPU would cause a POST failure, not an OS loading issue. A faulty power supply would affect system stability during POST, not specifically OS boot failure unless the system is not powering at all.
Thus, the failed component is the HDD.
