Questions in: Network & Telecom

Right Answer:
IP Splicing, also known as IP Hijacking, is a technique where an attacker takes control of an IP address that is not assigned to them, allowing them to intercept, redirect, or manipulate network traffic intended for that IP address.

Right Answer:
Challenge/Response is an authentication method where a server sends a challenge (a random number or string) to a client, and the client must respond with a valid response generated using a secret key or password. This process verifies the client's identity without transmitting the actual password.

Right Answer:
A Trojan Horse is a type of malicious software that disguises itself as a legitimate program to trick users into installing it, allowing attackers to gain unauthorized access to the user's system.

Right Answer:
Least Privilege is a security principle that grants users and systems the minimum level of access necessary to perform their tasks, reducing the risk of unauthorized actions or breaches.

Right Answer:
To access broadband, you need a modem and a router (if using multiple devices), along with a broadband connection from an Internet Service Provider (ISP).

Right Answer:
c) Tx & Rx should be visible to each other

Right Answer:
A tunneling router is a device that encapsulates data packets within another protocol to enable secure communication over a network, often used to connect remote networks or users through a virtual private network (VPN).

Right Answer:
A cryptographic checksum is a value generated from data using a cryptographic hash function, which ensures data integrity by allowing verification that the data has not been altered.

Right Answer:
c) 255

Right Answer:
Switches are networking devices that connect devices within a local area network (LAN) and use MAC addresses to forward data to the correct destination.

Layer-3 switches, also known as multilayer switches, operate at the network layer (Layer 3) of the OSI model. They can perform routing functions in addition to switching, allowing them to route traffic between different VLANs (Virtual Local Area Networks) and manage IP addresses. This enables more efficient data handling and improved network performance.

Right Answer:
b) common channel signaling

Right Answer:
A matrix is a rectangular array of numbers, symbols, or expressions arranged in rows and columns.

Right Answer:
A Virtual Network Perimeter is a security boundary that protects a virtual network by controlling access and monitoring traffic between the virtual network and external networks, ensuring that only authorized users and devices can communicate with it.

Right Answer:
You must configure a DHCP relay agent (also known as IP Helper) on the router to forward DHCP requests from the JumpStart clients to the DHCP server.

Right Answer:
A Data Driven Attack is a type of cyber attack where the attacker manipulates input data to exploit vulnerabilities in a system, often aiming to gain unauthorized access, execute malicious code, or extract sensitive information.

Right Answer:
Logging is the process of recording events, activities, or transactions in a system, typically for monitoring, troubleshooting, and auditing purposes.

Right Answer:
Defense in Depth is a security strategy that uses multiple layers of protection to safeguard information and systems, ensuring that if one layer fails, others still provide security.

Right Answer:
Abuse of privilege refers to a situation where an individual uses their authorized access to systems, data, or resources inappropriately or for unauthorized purposes, often leading to security breaches or violations of policies.

Right Answer:
A proxy is an intermediary server that acts as a gateway between a user and the internet, allowing requests to be sent and responses to be received while hiding the user's IP address and providing additional security or filtering.
