CompTIA 220-1202 Practice Test - Questions Answers

Modern authenticator apps (such as Microsoft Authenticator or Google Authenticator with push capability) can send a push notification to the user's registered device. The user approves or denies the login request via the notification, providing a quick and secure second factor for authentication.

RDP (Remote Desktop Protocol): Allows the user to connect to and control the Windows PC's desktop environment from home.

VPN (Virtual Private Network): Establishes a secure tunnel into the office network so the user's home device can reach the Windows PC before initiating the RDP session.

Linux distributions are open-source and generally free of licensing fees, making them suitable for both desktop workstations and servers. Organizations can use the same Linux OS across all their systems without incurring per-seat or per-server costs, unlike proprietary systems such as Windows or macOS.

Streaming HD video requires substantial network throughput, typically several Mbps. With only a 3G connection showing two bars, the available bandwidth is likely too limited or inconsistent to sustain an HD stream, resulting in timeouts.

The completed configuration:

1. Wireless AP (LAN side)

1. LAN IP: 192.168.10.1

2. Encryption: WPA2 PSK

2. Router (port-forward rule)

1. Allow TCP Any 3389

This forwards inbound RDP traffic (TCP/3389) from the Internet to the Windows PC, enabling Remote Desktop access.

3. Firewall (screened subnet side)

1. LAN IP: 10.100.0.1

4. Device placement

1. PC: place behind the router (where the port-forward rule points).

2. Game console: place on the Wireless AP (so it can use chat and extra services over WPA2 PSK).

3. Firewall: place in front of the screened subnet (with its 10.100.0.1 IP facing that subnet).

Comprehensive and Detailed Explanation From Exact Extract:

The correct answer is VNC (Virtual Network Computing). VNC is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It is platform-independent and widely supported on Linux, which makes it ideal for providing interactive remote support for a Linux-based operating system. It allows the technician not only to view the remote desktop session but also to control it, fulfilling the need to see and interact with the user's session.

A . VPN (Virtual Private Network) creates a secure tunnel to a network but does not provide desktop sharing or session control by itself.

C . SSH (Secure Shell) provides secure command-line access to Unix/Linux systems but does not offer graphical desktop interaction, which is a requirement in this case.

D . RDP (Remote Desktop Protocol) is primarily a Microsoft protocol, and although it can be made to work on Linux, it is not natively supported on legacy Linux systems, and thus less suitable than VNC in this scenario.

CompTIA A+ 220-1102 Core 2 Objective

Reference:

Objective 1.8 -- Given a scenario, use features and tools of the operating system.

Under this objective, candidates are expected to be familiar with remote access technologies, including RDP, SSH, and VNC, and understand their appropriate uses and limitations on different platforms such as Windows and Linux.

Comprehensive and Detailed Explanation From Exact Extract:

The issue described---''domain cannot be found'' despite the ability to ping the server and access the internet---indicates a DNS resolution problem, not a network connectivity issue. The workstation is currently using public DNS servers (8.8.8.8 and 1.1.1.1) which cannot resolve internal domain names, such as the ones used in Active Directory environments. To resolve this, the technician needs to change the DNS settings to point to the internal DNS server, which in most domain setups is the domain controller itself (likely 192.168.1.10 in this case).

Here's the breakdown of the incorrect options:

B . Assign a static IP address: The IP is already assigned and functioning; the device can ping and reach the network and internet.

C . Configure a subnet mask: The subnet mask is appropriate for the network range (Class C /24).

D . Update the default gateway: The gateway is valid and allows internet access; this is not the issue.

CompTIA A+ 220-1102 Core 2 Objective

Reference:

Objective 1.8 -- Given a scenario, use features and tools of the operating system.

Under this objective, candidates must know how to troubleshoot OS-based network configurations, including proper DNS settings in domain environments.

In a structured change-management process, the very first step is to propose (or formally request) the change via a Request for Change (RFC). This ensures stakeholders review the need, assess risks, and determine the priority before any approvals, scheduling, or implementation occur.

Time-based one-time password (TOTP) MFA apps rely on accurate clock synchronization. Traveling can desynchronize the device's clock, causing generated codes to be invalid. Ensuring the smartphone's date/time (and time zone) are correct will typically restore MFA functionality immediately.
