Question 2 of 553
Which of the following would MOST likely be used to connect one or more devices to the Internet in a SOHO?
Answer

Suggested Answer

The suggested answer is D.

In a Small Office/Home Office (SOHO) environment, a router is most commonly used to connect one or more devices to the Internet. A router provides the necessary functionality to manage the connection between the local network and the Internet, allowing multiple devices to share a single Internet connection. It handles network address translation (NAT) and often includes additional features such as firewall security. A hub lacks the capability to manage Internet connections, an Ethernet gateway is a less commonly used term, and a wireless access point provides wireless connectivity but does not handle the primary Internet connection.

Answer

Suggested Answer

The issue here stems from DNS resolution due to the change in the IP address of ComputerA. Because of this change, the DNS cache on any other computer trying to communicate with ComputerA might contain outdated information. To resolve this issue, one should clear the DNS cache to ensure that the computer fetches the latest IP information. The commands are typically executed on the computer experiencing connectivity issues, in this case, ComputerB. Therefore, perform the following steps on ComputerB: 1. Type 'ipconfig /flushdns' and press Enter. This clears the local DNS cache. 2. To verify a successful connection, type 'ping ComputerA' and press Enter. You should see replies from the new IP address 10.10.10.20. This will confirm that the issue has been resolved and ComputerB is now able to communicate with ComputerA using its name.

Question 5 of 553
A technician is troubleshooting what appears to be a RAM issue on a PC. Which of the following symptoms would indicate if this is a RAM issue?
Answer

Suggested Answer

The suggested answer is A.

POST code beeps are commonly used by computers to indicate hardware issues during the Power-On Self-Test (POST), and different beep patterns can specifically signify problems with RAM. Continuous reboots can result from various issues, including but not limited to power supply problems, motherboard failures, or even CPU issues. Distended capacitors typically indicate a problem with the motherboard or power supply, and the wrong BIOS time is usually related to a dead or dying CMOS battery. Therefore, the most direct and indicative symptom of a RAM issue would be POST code beeps.
