CompTIA Updated 220-1202 Exam Questions and Answers by adele

SSH (Secure Shell)allows encrypted console sessions to access and administer remote servers.

FromQuentin Docter – Complete Study Guide:

“Secure Shell (SSH) provides an encrypted console session to manage Linux, UNIX, or network devices securely over TCP port 22.” .

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).

The Windows PC is placed in the screened subnet (behind the firewall) for enhanced security. Remote access to this PC requires port forwarding of TCP port 3389 (RDP), which is correctly configured through the router.

The Game Console is placed on the Wireless AP LAN, using WPA2 PSK for a secure wireless connection. Game consoles typically use peer-to-peer chat and online services that require open access without firewall restrictions, which is why the console is not placed behind the firewall.

CompTIA A+ 220-1102 Reference Points:

Objective 3.4: Given a scenario, implement best practices associated with data and device security.

Objective 2.4: Given a scenario, use appropriate tools to support and configure network settings.

Study Guide Reference: CompTIA A+ Core 2 guides recommend using screened subnets (a type of DMZ) for systems needing controlled external access, such as remote desktops, while placing gaming and media devices on less restricted networks for full functionality.

First Chat Response:When the user mentions setting up a new router, the best initial response to maintain a helpful and professional tone is:

>Select reply:"I am happy to assist you today."

Second Chat Response:When the user states that they need to set up basic security settings:

>Select reply:"Is this the first router in your office?"

Third Chat Response:After learning it's a replacement router and the user is logged into the router's web page:

>Select reply:"The first thing you need to do is change the default password."

Fourth Chat Response:For the response about password settings:

>Select reply:"Create a new password with an uppercase, a lowercase, and a special character."

Fifth Chat Response:When the router prompts to reboot:

>Select reply:"Yes, reboot please."

Study Guide Reference: The CompTIA A+ Core 2 guide highlights the importance of changing default credentials and using strong password policies, particularly in SOHO environments where routers are often targeted.

Comprehensive and Detailed Explanation From Exact Extract:

Ransomware is a type of malware that encrypts the user's files and demands a payment (ransom) for the decryption key. When a user receives a message stating that their files are encrypted and cannot be accessed, ransomware is the most likely cause. The attacker’s goal is to hold the data hostage until the victim pays to restore access.

A. Keylogger records keystrokes and doesn’t encrypt files.

C. Phishing is a social engineering tactic to gather credentials, not to encrypt data.

D. Cryptominer uses system resources to mine cryptocurrency, not encrypt files.
