220-1101 Exam Dumps - CompTIA A+ Questions and Answers

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.

In Platform as a Service (PaaS), the cloud provider manages the hardware, operating system, and middleware, while the customer is responsible for managing data and applications.

Why Not B (SaaS): In SaaS, the provider manages all layers, including applications and data, leaving no responsibility for the customer.

Why Not C (IaaS): In IaaS, the customer manages the OS, data, and applications, while the provider only handles the hardware.

Why Not D (CaaS): CaaS (Container as a Service) is not a primary cloud model described in the CompTIA objectives and is less commonly referenced.

A loopback plug allows a technician to verify that the cable functions as expected by looping the signal back for testing. While a punchdown tool installs cables in a panel, it does not test functionality, and Wi-Fi analyzers and toner probes serve other network diagnostics. This is in line with CompTIA A+ Core 1 objectives for validating cable installation and connectivity.

Mobile Device Management (MDM) enables administrators to enforce controls on enterprise devices, such as restricting apps, ensuring compliance, and remotely managing security policies.

Why Not B (MFA): Multi-Factor Authentication secures user access but does not control device configurations.

Why Not C (VPN): VPN secures communication but does not enforce device controls.

Why Not D (SSL): SSL secures data in transit but does not provide device management.

Configuring the monitor as an "extended" display will allow the laptop and monitor to show different content. By default, laptops mirror displays, so this setting change enables dual display functionality. This is covered under CompTIA Core 1 exam objectives for managing display configurations and settings​.

Older motherboards use 20-pin connectors, while newer power supplies use 24-pin connectors. An adapter resolves the compatibility issue cost-effectively.

Why Not A (Adjust the input voltage): Input voltage adjustment is unrelated to connector compatibility.

Why Not B (Install a modular power supply): While modular supplies are versatile, this doesn’t address the connector issue directly.

Why Not C (Rebuild the failed power supply): Rebuilding is costly and complex compared to using an adapter.

CompTIA A+ Exam Reference: Core 1 (220-1101), Section 3.4, power supply compatibility​.

To terminate an RJ45 port, a technician should use a punchdown tool. This tool is specifically designed to insert and cut (terminate) the wires into a patch panel, keystone jack, or a network surface mount box. The punchdown tool ensures that the wire is properly seated in the terminal block and that the connection is secure. It also trims the excess wire during the termination process, which is not a function that cable testers, toner probes, or cable strippers are designed to perform.

The IP address 192.168.1.56 is within the private IP address range (192.168.0.0 to 192.168.255.255) and is appropriate for use in an internal network utilizing NAT (Network Address Translation). The other IP addresses provided (172.15.65.10, 175.16.20.3, and 193.167.35.4) are either public IP addresses or not in the private IP range suitable for an internal network using NAT.

Mobile Device Management (MDM) is the best solution for remotely managing security settings and configuring applications on tablets across branch offices. MDM allows administrators to control device security policies, push applications, track device locations, perform remote wipes, and manage many other aspects of mobile devices from a centralized console. While SSH, RDP, and VPN are useful for remote access and secure connections, they do not offer the comprehensive device management and configuration capabilities that MDM provides.

The ticking noise likely indicates a failing hard drive. The technician should attempt to extract data before the drive fails completely.

Removing unnecessary applications frees up storage and processing power, which may allow the device to sync data more effectively. Data caps, Preferred Roaming List settings, and Bluetooth discovery are unrelated to syncing large datasets in cloud storage, as noted in CompTIA A+ Core 1 objectives on mobile device troubleshooting.

The 12VHPWR connector can supply up to 600 watts of power, designed for high-end graphics cards.

Why Not A (400W): This is less than the connector’s maximum capability.

Why Not B (MOW): This is an invalid option.

Why Not D (700W): The maximum supported power is 600W.

The digitizer converts touch inputs into digital signals, enabling touch functionality on a monitor. This component is essential for touch screens to process user input and is covered under the CompTIA A+ Core 1 objective on display technologies for mobile devices​.

To make sure that the new operating system on the USB drive loads automatically, the user must configure the boot options in the BIOS/UEFI. Boot options determine the sequence of devices the computer will attempt to boot from when powered on. Setting the USB drive as the first boot option ensures that the system will load from the USB before trying other devices.

D. Boot options: The user should configure the boot sequence to prioritize the USB drive, so the system boots from it automatically.

Why the other options are incorrect:

A. BIOS password: A BIOS password is used to restrict access to the BIOS settings, not to control boot order.

B. Trusted Platform Module (TPM): TPM is a security feature used for cryptographic operations and securing hardware, not for controlling boot options.

C. USB permissions: This refers to access permissions for USB devices but does not affect booting from a USB drive.

This concept is part of the Hardware domain in the CompTIA A+ Core 1 exam, specifically regarding BIOS configuration​.

The IPv4 address (192.168.10.5) and the gateway address (192.168.1.1) are on different subnets. With a netmask of 255.255.255.0, the network part of the IPv4 address is 192.168.10.x, while the network part of the gateway address is 192.168.1.x. For the workstation to correctly route traffic to the gateway, both must be on the same subnet. The correct gateway address should be within the same subnet as the IPv4 address, such as 192.168.10.1.
