Question 1

Networking devices allow the computers on a network to interact with each other.

Accepted Answer

Networking devices, such as routers, switches, and hubs, facilitate the connection and communication between computers on a network, enabling them to share data and resources.

Question 2

A proxy server is hard to use since it is usually not included in router or firewall software.

Accepted Answer

Proxy servers are often included as a feature in router or firewall software, making them relatively easy to implement and use for network administrators.

Question 3

The user interacting via the proxy server is hidden, but can be traced through the log stored on the proxy server.

Accepted Answer

Proxy servers can log user activities, including IP addresses and requests, making it possible to trace the user's actions back to them if those logs are accessed.

Question 4

Routers and switches both segment a network, and all can filter packets.

Accepted Answer

Routers segment a network into different subnets and can filter packets based on IP addresses, while switches primarily operate within a single subnet, forwarding packets based on MAC addresses and do not inherently filter packets.

Question 5

Hackers can perform many attacks on routers and switches even if they cannot get into the building and set themselves up as a system administrator.

Accepted Answer

Hackers can exploit vulnerabilities in routers and switches remotely through the internet or a network connection, using techniques such as malware, phishing, or exploiting software vulnerabilities, without needing physical access to the devices or administrative privileges.

Question 6

A network can be divided into two main areas: networking software and networking ____.&#10;A)agents&#10;B)devices&#10;C)programs&#10;D)robots

Accepted Answer

Networking is broadly divided into two main areas: networking software and networking devices. Networking devices include routers, switches, hubs, and modems, which are essential for creating and managing networks.

Question 7

Networking software can be divided into three categories: security software, ____ software, and transport software.&#10;A)presentation&#10;B)routing&#10;C)connection&#10;D)linking

Accepted Answer

The answer of Networking software can be divided into three...

Question 8

The attacks made through proxy servers include buffer overflow attacks, denial-of-service attacks, and ____ attacks.&#10;A)session-hijacking&#10;B)password cracking&#10;C)switch cracking&#10;D)router hijacking

Accepted Answer

Session-hijacking attacks are commonly associated with proxy servers, as they involve intercepting and taking over an active user session, which can be facilitated through the use of proxies.

Question 9

____ are a form of logical network segmentation.&#10;A)VPNs&#10;B)VRNs&#10;C)VEs&#10;D)VLANs

Accepted Answer

VLANs (Virtual Local Area Networks) are a form of logical network segmentation that allow network administrators to group hosts together even if they are not directly connected to the same network switch. This is done for efficiency, security, and ease of management.

Question 10

____ are often considered the ultimate one-point solution for securing networks from both internal and external threats.&#10;A)VPNs&#10;B)Routers&#10;C)Firewalls&#10;D)Switches

Accepted Answer

Firewalls are designed to inspect and filter incoming and outgoing network traffic based on an organization's previously established security policies. At its most basic, a firewall can block traffic meant to harm networks, while allowing legitimate communication to pass, thus acting as a barrier against many types of cyber threats from both inside and outside an organization.
