By default, Telnet uses port ____ to connect to a remote host.
- A.
20
- B.
21
- C.
23
- D.
80
Correct Answer
C. 23Explanation
Telnet is a network protocol used to establish a remote connection with a host. By default, Telnet uses port 23 to connect to a remote host. This port is specifically assigned for Telnet communication. Ports 20 and 21 are used for FTP (File Transfer Protocol), while port 80 is used for HTTP (Hypertext Transfer Protocol). Therefore, the correct answer is 23.Rate this question:

When you load a kernel module, you do not need to specify the path to the module’s directory.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When you load a kernel module, you do not need to specify the path to the module's directory because the kernel is already aware of the default directories where the modules are located. The kernel is designed to search for the module in these default directories, so you only need to specify the module's name when loading it. This allows for easier and more convenient loading of kernel modules without the need to provide the full path every time.Rate this question:

Ping ____ to check that the internal networking stacks are functioning and that networking is enabled in the Linux kernel.
- A.
127.0.0.1
- B.
128.0.0.1
- C.
128.0.0.254
- D.
128.0.1.255
Correct Answer
A. 127.0.0.1Explanation
The correct answer is 127.0.0.1. This IP address is the loopback address, also known as localhost, which is used to test the network functionality on a local machine. When a device sends a ping request to 127.0.0.1, it is essentially testing its own network stack and verifying that networking is enabled in the Linux kernel.Rate this question:

The ____ option of the ping command lists all of the intervening routers that your ping packet passed through to reach the destination host.
- A.
-a
- B.
-f
- C.
-i
- D.
-r
Correct Answer
D. -rExplanation
The "-r" option of the ping command lists all of the intervening routers that your ping packet passed through to reach the destination host. This option can be used to trace the route that the packet takes, helping to identify any network connectivity issues or bottlenecks along the way.Rate this question:

IP ____ enables you to assign more than one IP address to an interface.
- A.
Aliasing
- B.
Indexing
- C.
Masking
- D.
Tracing
Correct Answer
A. AliasingExplanation
The term "aliasing" in the context of IP addresses refers to the ability to assign multiple IP addresses to a single network interface. This can be useful in situations where a device needs to communicate with multiple networks or when multiple services need to be hosted on the same device. By assigning multiple IP addresses to a single interface, the device can effectively handle multiple network connections simultaneously.Rate this question:

When the Network Configuration Tool starts, the ____ tab is selected.
- A.
Devices
- B.
Hardware
- C.
DNS
- D.
Hosts
Correct Answer
A. DevicesExplanation
When the Network Configuration Tool starts, the "Devices" tab is selected. This is because the Network Configuration Tool is used to manage and configure network devices. The "Devices" tab allows users to view and manage the network devices connected to the system, such as network interfaces, Ethernet adapters, wireless devices, etc. By selecting the "Devices" tab, users can easily access and configure the settings of these devices to ensure proper network connectivity and functionality.Rate this question:

The MTU (maximum transmission unit) for Ethernet always defaults to ____.
- A.
250
- B.
1000
- C.
1500
- D.
2000
Correct Answer
C. 1500Explanation
The MTU (maximum transmission unit) for Ethernet always defaults to 1500. This is the standard value for Ethernet networks and represents the maximum size of the data packet that can be transmitted in a single frame without fragmentation. This default value ensures compatibility and efficient data transmission across Ethernet networks.Rate this question:

The ____ column output by the route command specifies the number of hops this particular route represents.
- A.
Ref
- B.
Iface
- C.
Flags
- D.
Metric
Correct Answer
D. MetricExplanation
The "Metric" column output by the route command specifies the number of hops this particular route represents. The metric is a value used by routing protocols to determine the best path for forwarding network traffic. It is typically based on factors such as the speed or reliability of the route. The lower the metric value, the more preferred the route is. Therefore, the metric column provides information about the number of hops or the quality of the route.Rate this question:

Traceroute relies on the ____ field and ICMP “packet timed out” messages to move step-by-step through the Internet to reach the host in which you are interested.
- A.
TTL
- B.
Identification
- C.
Protocol
- D.
Header Checksum
Correct Answer
A. TTLExplanation
Traceroute relies on the TTL (Time to Live) field and ICMP "packet timed out" messages to move step-by-step through the Internet to reach the host in which you are interested. The TTL field is used to limit the lifespan of a packet and prevent it from circulating indefinitely in the network. As the packet travels through routers, the TTL value is decremented by each hop. When the TTL reaches zero, the router discards the packet and sends an ICMP "packet timed out" message back to the source. Traceroute utilizes this mechanism to determine the path and measure the latency of packets to a specific destination.Rate this question:

The loopback interface exists as a physical device.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The loopback interface does not exist as a physical device. It is a virtual network interface that allows a device to communicate with itself. It is often used for testing and troubleshooting purposes. Unlike physical interfaces, the loopback interface does not require any external connections or hardware. It is solely used for internal communication within the device itself.Rate this question:

To use Telnet as a terminal emulator program, you must connect to a host running a Telnet ____.
- A.
Server
- B.
Interface
- C.
Interpreter
- D.
Client
Correct Answer
A. ServerExplanation
To use Telnet as a terminal emulator program, you must connect to a host running a Telnet server. The Telnet server is responsible for accepting incoming Telnet connections and providing access to the host's command line interface or other services. The server listens for incoming connections on a specific port and allows clients to establish a Telnet session, enabling them to remotely access and control the host system.Rate this question:

The utility that you use to send ICMP echo packets is called ____.
- A.
Ip
- B.
Ifconfig
- C.
Route
- D.
Ping
Correct Answer
D. PingExplanation
The utility that is used to send ICMP echo packets is called "ping". This utility is commonly used to test the connectivity between two devices on a network by sending echo requests and waiting for echo replies. It helps to determine if a remote host is reachable and measure the round-trip time for the packets to travel. The "ping" command is available on most operating systems and is a fundamental tool for network troubleshooting and diagnostics.Rate this question:

Table that contains a mapping of IP addresses to interface hardware addresses.
Correct Answer
ARP cache
ARP Cache
arp
ARPExplanation
The table that contains a mapping of IP addresses to interface hardware addresses is called the ARP cache. ARP (Address Resolution Protocol) is used to map an IP address to a physical (MAC) address on a local network. The ARP cache stores these mappings temporarily to speed up future communication between devices.Rate this question:

Traditional way of viewing and controlling network interfaces.
Correct Answer
ifconfig program, ifconfig, Ipconfig, ipconfigExplanation
The correct answer includes three options: ifconfig program, Ipconfig, and ipconfig. These options refer to different commands or programs used to view and control network interfaces. "ifconfig" is a command used in Unix-like operating systems, while "Ipconfig" is a command used in Windows operating systems. "ipconfig" is another command that is similar to "Ipconfig" but is used in Linux and macOS. These commands provide information about network interfaces, such as IP addresses, subnet masks, and other network configuration details.Rate this question:
