Enterprise networks, no matter campus networks or DCNs, are facing a lot of potential attacks. What are the common types of attack methods we are facing? (Select All that Apply)
Correct Answer:ABCD
Common Attack Methods in Enterprise Networks:
Enterprise networks are vulnerable to various cyberattacks, targeting both infrastructure and applications.
Explanation of Each Attack Method:
Command line injection:Exploits vulnerabilities in command-line interfaces to execute unauthorized commands.
Brute-force attacks:Attempts to guess passwords or encryption keys through exhaustive trial-and-error methods.
Cross-site attacks:Includes cross-site scripting (XSS) and cross-site request forgery (CSRF), targeting web applications.
Remote code execution:Exploits vulnerabilities to execute arbitrary code on a target system, often leading to full system compromise.
Conclusion:All four options represent common attack methods faced by enterprise networks.

Which of the following protocols operate at the network layer? (Select All that Apply)
Correct Answer:ABCE
Understanding the Network Layer:
The network layer (Layer 3 of the OSI model) is responsible for end-to-end packet delivery, including routing and addressing. Protocols operating at this layer handle logical addressing and path determination.
Explanation of Each Protocol:
IPv6:The next-generation Internet Protocol, which operates at the network layer to provide addressing and routing for packets.
ICMPv6:Internet Control Message Protocol version 6, used for error reporting and diagnostic functions in IPv6 networks. It operates at the network layer.
IPv4:The current widely-used Internet Protocol, which operates at the network layer to provide addressing and routing for packets.
OSPF:Open Shortest Path First is a dynamic routing protocol that operates at the network layer to exchange routing information between routers.
ICMP:Internet Control Message Protocol, used for error reporting and diagnostic functions in IPv4 networks. It operates at the network layer.
Conclusion:IPv6, ICMPv6, IPv4, and ICMP all operate at the network layer. OSPF is also correct because it is a routing protocol that works at Layer 3.

Wide area network (WAN) covers a large geographical area, ranging from dozens of kilometers to thousands of kilometers. It can connect multiple cities or even countries and provide long-distance communication to form an international large-scale network.
Correct Answer:A
A Wide Area Network (WAN) is designed to span large geographical areas, such as cities, regions, or even countries. WANs enable long-distance communication and are typically used to connect multiple Local Area Networks (LANs) or Metropolitan Area Networks (MANs). They rely on technologies like MPLS, SD-WAN, and leased lines to provide connectivity over vast distances.
The description provided in the question accurately reflects the characteristics and purpose of a WAN. Therefore, the statement is TRUE .
