Unit 3 Review

Automatically slows down the computer allowing it to cool down.

• Overclocking
• Disk defragmentation
• Memory upgrade
• Thermal throttling

Answer explanation

Thermal throttling automatically slows down the computer's performance to reduce heat generation, allowing it to cool down. This is a protective measure to prevent overheating, unlike cooling systems that actively dissipate heat.

Ava is troubleshooting her laptop because it's not performing well. What should she consider when dealing with issues caused by her device?

• CPU usage

• Memory

• Temperature

• All of the above

Answer explanation

When addressing device issues, it's crucial to consider CPU usage, memory, and temperature, as all can impact performance and functionality. Therefore, the correct answer is 'All of the above'.

During a computer networking class, Oliver asked, "What is the maximum transfer throughput capacity of a network, being measured in bits, megabits, or gigabits per second?"

Answer explanation

Bandwidth is the maximum transfer throughput capacity of a network, measured in bits, megabits, or gigabits per second. It indicates how much data can be transmitted in a given time, making it the correct choice.

Michael is experiencing issues with his video calls at home. What are the main two causes of network jitter he might be facing?

• Network congestion and wireless connection

• Router changes and outdated equipment

• Outdated equipment and wireless connection

• Network congestion and route changes

Answer explanation

Network jitter is primarily caused by network congestion, which leads to delays in data packets, and route changes, which can disrupt the flow of data. Thus, the correct answer is network congestion and route changes.

Latency is a measurement of ______ in a network.

• signal strength
• speed

• time delay
• bandwidth

Answer explanation

Latency is a measurement of delay in a network, indicating the time it takes for data to travel from one point to another. Therefore, the correct answer is 'delay'.

Ethan is setting up a new network for his small business. He wants to ensure that the network operates efficiently and meets expected performance levels. What is the standard level of performance of a device or network called?

• Baseline

• Bottom line

• Availability

• Data flow level

Answer explanation

The standard level of performance for a device or network is referred to as the 'Baseline'. It serves as a reference point for measuring performance and identifying deviations.

Luna is working on a network project and needs to track TCP/IP flows within the network. Which protocol should she use as a powerful tool for this purpose?

• DHCP

• HTTP

• Syslog

• SNMP

Answer explanation

SNMP (Simple Network Management Protocol) is designed for network management and monitoring, making it a powerful tool for tracking TCP/IP flows within a network. The other options serve different purposes.

Daniel is responsible for maintaining the company's network. If the network has an uptime of four nines, how is that represented in percentage?

• 99.9%

• 99.99%

• 99.999%

• 99.9999%

Answer explanation

Uptime of four nines means 99.99%. Each 'nine' represents a decimal place, so four nines translates to 99.99%, indicating the network is operational 99.99% of the time.

Sophia is working on a project that involves monitoring network devices. She needs to use a protocol that utilizes OIDs and MIBs for data collection. Which protocol should she use?

• HTTPS

• TCP

• SNMP

• FTP

Answer explanation

The Simple Network Management Protocol (SNMP) uses Object Identifiers (OIDs) and Management Information Bases (MIBs) to manage and monitor network devices, making it the correct choice for this question.

Network watchdogs called agents send an alert called a(n) ______ to the management station if something isnt functioning properly.

• incident

• trap

• emergency

•  reconnaissance

Answer explanation

In networking, a 'trap' is an alert sent by agents to the management station when an issue arises. This term specifically refers to the notification mechanism used for monitoring network devices.
