Use Remote Access Technologies

Question 1

Answer 1

Remote Desktop Connection client (mstsc.exe).

Question 2

Answer 2

Configuring Remote Desktop server settings.

Question 3

Answer 3

Using Remote Assistance.

Question 4

Answer 4

Confirming the SSH server’s host key.

Question 5

Remote desktop

Answer 5

enables users to work on a different computer over a network by running a terminal server, often used for remote work or IT troubleshooting via VPN access.

Question 6

Remote access security

Answer 6

requires least privilege permissions, encrypted connections, secure server authentication, and vulnerability management, especially for internet-exposed ports.

Question 7

Remote Desktop Protocol (RDP)

Answer 7

In windows, for terminal server and client functionality. To connect, open Remote Desktop Connection or run mstsc.exe, enter the server’s IP address or FQDN, and verify the certificate for security.

Question 8

To authenticate on an RDP session

Answer 8

use Domain\Username for domain accounts or .\Username/Host\Username for local accounts. RDP encryption ensures credentials and session data remain secure from network interception.

Question 9

RDP

The mstsc client is available

Answer 9

for Linux, macOS, iOS, and Android, enabling devices on these platforms to establish RDP connections to Windows servers for remote access.

Question 10

Virtual Network Computing (VNC)

Answer 10

is an alternative to RDP for remote access. macOS uses Screen Sharing, which relies on VNC and allows connections via any VNC client. VNC operates over TCP port 5900, but not all versions support secure connections—macOS Screen Sharing ensures encryption.

Question 11

Remote Desktop servers

Answer 11

require access control, Network Level Authentication (NLA) for security, Restricted Admin Mode to protect credentials, and can run on TCP port 3389, with open-source alternatives like XRDP for Linux.

Question 12

Microsoft Remote Assistance (MSRA)

Answer 12

allows users to request help via an invitation file, while Quick Assist (CTRL+START+Q) offers an alternative using TCP/443 with encryption, requiring a Microsoft account for secure access.

Question 13

Secure Shell (SSH)

Answer 13

enables remote command-line access using TCP port 22 and encryption. Servers authenticate via a public/private key pair and host key fingerprint to prevent on-path attacks. Key management can be handled manually or with enterprise tools.

Question 14

SSH host key pair

Answer 14

SSH uses a host key pair to establish encryption, with authentication via password or public key, ensuring secure remote access.

Question 15

Network visibility

Answer 15

ensures authorized hosts operate securely, relying on remote monitoring and management tools rather than manual inspections. These technologies help technicians oversee configurations and detect anomalies across the network efficiently.

Question 16

**Remote monitoring and management (RMM)

Answer 16

tools** help managed service providers (MSPs) oversee client IT systems, track activity, and report billable support efficiently.

Question 17

Desktop management

Answer 17

including Unified Endpoint Management (UEM) and Mobile Device Management (MDM) suites, helps organizations enforce access control and authorization for secure device administration. Let me know if you want to explore their features further!

Question 18

locally installed agent

Answer 18

gathers status, log, and inventory data for a management server, integrating with help desk systems. Most suites support Windows, Linux, macOS, iOS, and Android devices for comprehensive oversight.

Question 19

agent with Endpoint Detection and Response (EDR) capabilities

Answer 19

enhances security by scanning for threats, detecting anomalies, and responding to potential breaches. It helps organizations proactively identify, isolate, and mitigate security risks across managed endpoints.

Question 20

Automated push deployment

Answer 20

streamlines upgrades, updates, security definitions, app installations, and script execution while ensuring license compliance across managed devices.

Question 21

Wake on LAN (WOL)

Answer 21

enables remote network boot functionality, allowing administrators to power on devices remotely. Advanced management tools can also facilitate system firmware access, firmware updates, and OS installations for streamlined maintenance and deployment.

Question 22

Access control enforcement

Answer 22

ensures that devices failing OS version, update, or health policy compliance are prevented from connecting to the network, reducing security risks and unauthorized access.

Question 23

Remote management suites

Answer 23

often include live chat, remote desktop, and remote shell access, enabling technicians to interact with users and directly troubleshoot systems without physical access.

Question 24

software agent

Answer 24

requires the OS to be active for communication with the management server, but out-of-band (OOB) management via Intel vPro or AMD PRO allows remote power control and system access even when the OS is offline.

Question 25

**alternative remote access tools**

Answer 25

For smaller environments like SOHO networks, **alternative remote access tools** can provide cost-effective solutions for managing **non-Windows devices**. These protocols and software options help administrators maintain network oversight without the expense of enterprise monitoring suites.

Question 26

Third-party **screen-sharing software**

Answer 26

like **TeamViewer** and **LogMeIn** provides remote control functionality over **HTTPS (TCP/443)**, ensuring encryption while avoiding complex firewall configurations. Some require local installation, while others run non-persistently. Users grant access using a **PIN code**, but organizations should enforce **out-of-band verification** to prevent social engineering attacks.

Question 27

Video-conferencing software

Answer 27

like **Microsoft Teams** and **Zoom** offer **screen-sharing**, allowing users to share a **window or entire desktop**, with optional participant control for demonstrations and troubleshooting.

Question 28

File transfer

Answer 28

software simplifies sharing files without requiring complex **network file share** configurations, ensuring compatibility across hosts and streamlining permissions.

Question 29

AirDrop

Answer 29

available on **Apple iOS** and **macOS**, uses **Bluetooth** to initiate a **Wi-Fi Direct** connection for file transfers, ensuring security through **Bluetooth pairing** and **Wi-Fi encryption**.

Question 30

**Near Sharing**

Answer 30

introduced in **Windows 10 (1803)**, is **Microsoft’s equivalent of AirDrop**, allowing seamless file transfers between devices using **Wi-Fi and Bluetooth** without complex network configurations.

Question 31

**Nearby Share**

Answer 31

designed for **Android devices**, enables **Bluetooth-powered file sharing**, allowing seamless transfers without requiring a direct internet connection.

Question 32

**Virtual Private Network (VPN)**

Answer 32

creates a **tunneled connection** between a local computer and a remote network, enhancing security. Instead of exposing **remote desktop ports**, users can **establish a VPN first**, then connect via **Remote Desktop Protocol (RDP)**, reducing firewall vulnerabilities.
