Virtual Employee Cyber Security Analyst Interview Questions, Process, and Tips

MGCP, SIP, and SCCP are protocols used in telecommunications for controlling communication sessions.

• MGCP (Media Gateway Control Protocol) is used for controlling media gateways in VoIP networks.

• SIP (Session Initiation Protocol) is used for initiating, maintaining, and terminating real-time sessions like voice and video calls over IP networks.

• SCCP (Skinny Client Control Protocol) is a Cisco proprietary protocol used for...read more

Logs can be collected using various methods such as syslog, SNMP, agent-based monitoring, and log management tools.

• Use syslog to collect system logs from network devices

• Utilize SNMP to gather performance data and alerts from network devices

• Deploy agent-based monitoring tools on servers to collect detailed logs

• Implement log management tools like Splunk or ELK stack for centralized log collection and analysis

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven different layers.

• The OSI model stands for Open Systems Interconnection model.

• It helps in understanding how different networking protocols work together.

• Each layer has a specific function and communicates with the layers above and below it.

• Examples of layers include physical layer, data link laye...read more

The OSI model consists of 7 layers that define the functions of a network.

• The 7 layers of the OSI model are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and protocols associated with it.

• For example, the Physical layer deals with the physical connection between devices, while the Application layer handles user interfaces.

Routers connect multiple networks together, while switches connect devices within a single network.

• Routers operate at the network layer (Layer 3) of the OSI model, while switches operate at the data link layer (Layer 2).

• Routers use IP addresses to forward data between networks, while switches use MAC addresses to forward data within a network.

• Routers determine the best path for data packets to reach their destination, ...read more

The statement is incorrect. Routers route between different networks, while switches connect devices within the same network.

• Routers route traffic between different networks based on IP addresses

• Switches connect devices within the same network based on MAC addresses

• Example: A router connects a home network to the internet, while a switch connects devices within the home network

Public IP is the address assigned to a device connected to a network, accessible over the internet. Private IP is used within a private network.

• Public IP is unique and globally routable

• Private IP is used within a local network and not accessible over the internet

• Public IP allows devices to communicate with other devices on the internet

• Private IP allows devices to communicate within the local network

• Example of public IP

STP stands for Spanning Tree Protocol, a network protocol used to prevent loops in Ethernet networks.

• STP is used to create a loop-free logical topology in a network.

• It works by selecting a root bridge and calculating the shortest path to reach each network segment.

• STP uses a tree-like structure to block redundant paths and ensure data flows efficiently.

• It helps in preventing broadcast storms and improving network stabi
