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

The technician should check the MAC filtering list next as the new router may have a different MAC address than the old router. References: CompTIA A+ Certification Exam Guide, Exam 220-1001, Page 332

RAID 10 array is often used for server virtualization as it provides both redundancy and performance benefits. It uses a combination of mirroring and striping to provide both fault tolerance and improved I/O performance. An optical disk drive or eMMC storage device would not provide enough storage or performance for a VM host server, while a 15,000rpm drive may provide good performance but would not provide redundancy for fault tolerance. Therefore, a RAID 10 array is the best option for cost-effective storage that will be used for all VMs that run from the server.

The most likely action that would resolve the issue is to clean the keyboard. Sometimes dust, hair, and other debris can affect keyboard functionality. The technician can try to clean the keyboard as much as possible, which may be enough to get the keyboard back in working order

Comprehensive and Detailed Step-by-Step Explanation:To answer this question, we need to identify the port numbers associated with email protocols used in client-server communication.

Port 25 (SMTP - Simple Mail Transfer Protocol):

This port is primarily used for sending emails between mail servers and from mail clients to mail servers (sending outbound mail).

SMTP is an essential protocol for email traffic.

Printers that use PostScript drivers are designed to handle complex printing tasks, including detailed graphics and images in PDF files. However, if the printer's PostScript driver is outdated, incompatible, or improperly configured, it may struggle to process and print PDF files containing images. Updating or reinstalling the PostScript driver, or choosing a different driver compatible with the printer and document type, can resolve this issue.

The connection type that the technician should recommend is Satellite. Satellite internet is a good option for people who travel around the world and want to have connectivity while visiting remote camping locations. It works by using terminals which can give you internet access in remote locations as long as they have a line of sight to the satellite in orbit above12.

Since the customer travels to remote camping locations with limited or unreliable cellular service, the best recommendation is satellite internet connection. Satellite internet uses a dish to connect to satellites orbiting the earth, which can provide coverage anywhere in the world as long as there is a clear line of sight to the satellite. This is especially useful in remote areas where traditional terrestrial connections are not available.

An administrator would use Infrastructure as a Service (IaaS) to migrate virtual machines from on-premises to the cloud. IaaS is a cloud computing service that provides virtualized computing resources, such as servers, storage, and networking, that can be used to deploy and run applications in the cloud. By using IaaS, an administrator can create a virtual machine in the cloud and migrate the existing virtual machine from on-premises to the cloud.

A VLAN (Virtual Local Area Network) segments a physical network into separate logical networks, enhancing security by isolating traffic.

Why Not A (Minimizes collision domains): VLANs manage broadcast domains, not collision domains.

Why Not B (Provides private access to cloud resources): VLANs operate within a local network, not cloud-specific.

Why Not C (Increases network address space): VLANs do not affect address space.

CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.6, VLAN concepts​.

Mobile Device Management (MDM) policies are crucial for companies that allow employees to use personal devices for work duties. MDM enables the company to enforce security policies, manage and secure corporate data on personal devices, and ensure compliance with company standards. It allows for remote management of these devices, including the ability to remotely wipe company data if the device is lost or stolen, without impacting personal data, thereby protecting company information effectively.

An imaging drum is a component of a laser printer that transfers the toner to the paper. It is sensitive to light and can wear out over time, resulting in poor print quality or missing colors. If the cleaning cycle does not resolve the issue, the imaging drum may need to be replaced1.

A fuser is a component of a laser printer that heats and melts the toner onto the paper. It does not affect the color output of the printer, but it can cause paper jams, smudges, or wrinkles if it is defective2.

An ink cartridge is a component of an inkjet printer, not a laser printer. A laser printer uses toner, which is a dry powder, instead of ink, which is a liquid. An ink cartridge would not be compatible with a laser printer3.

A toner tank is a container that holds the toner for a laser printer. It can be either integrated with the imaging drum or separate from it. If the toner tank is empty or low, the printer will display a warning message and the print quality will deteriorate. However, if only one color is missing, the problem is more likely with the imaging drum than the toner tank4.

Resin is a material that is used in some types of 3D printers, not laser printers. Resin printers use a liquid resin that is cured by a light source to create solid objects. Resin has nothing to do with laser printing5.

A hotspot provides a redundant internet connection using cellular data. This ensures connectivity for the meeting even if the primary ISP connection fails.

Why Not A (Wireless access point): A wireless access point expands Wi-Fi connectivity but does not provide internet redundancy.

Why Not B (Near-field communication): NFC is used for short-range communication, not internet connectivity.

Why Not D (Bluetooth): Bluetooth is for short-range device pairing and cannot serve as a backup internet connection.

CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.7, internet connection types and redundancy​.

Hubs operate in half-duplex mode and are limited to low speeds like 10Mbps, making them the most likely cause for the network card's performance issue.

Why Not A (DSL): DSL relates to internet connectivity, not local network hardware.

Why Not B (Unmanaged switch): Unmanaged switches typically support full-duplex and higher speeds than 10Mbps.

Why Not C (NIC teaming): NIC teaming increases bandwidth and redundancy, and is not relevant to this issue.

In the SaaS (Software as a Service) model, the service provider manages the infrastructure, platforms, and software applications, including maintenance tasks such as application patching. Users access the applications over the internet, and the provider is responsible for ensuring the software is up to date, secure, and performing optimally. This model contrasts with IaaS (Infrastructure as a Service) and PaaS (Platform as a Service), where the customer has more control and responsibility over the environment and may need to manage patching for applications they develop or install.

References: SaaS is designed to relieve users from the complexity of software maintenance, including patch management, as highlighted in cloud computing service model descriptions.

Comprehensive and Detailed Step-by-Step Explanation:

Wi-Fi Analyzer:

A Wi-Fi analyzer is a tool used to detect and analyze wireless networks, even those that are not broadcasting their SSIDs (hidden networks).

It provides detailed information about nearby networks, including signal strength, channel usage, and security protocols.

In this case, the Wi-Fi analyzer can identify the hidden networks that users are connected to, which are not visible on the standard user interface.

Incorrect Options:

A. Cable tester: A cable tester is used to test the integrity of physical network cables. It does not detect wireless networks or SSIDs.

B. Toner probe: A toner probe is used to trace and identify cables within a wiring system. It is not applicable to wireless network analysis.

D. Loopback plug: A loopback plug is used to test the functionality of a network port or NIC. It is unrelated to identifying hidden wireless networks.

A firewall monitors and filters incoming and outgoing network traffic based on security rules, protecting the network from unauthorized access and threats.

Why Not A (Switch): A switch connects devices within a network but does not monitor or filter traffic.

Why Not B (Access point): An access point provides Wi-Fi connectivity but does not filter traffic.

Why Not D (Hub): A hub simply broadcasts data to all connected devices without filtering traffic.
