HPE Aruba Network Architecture

Aruba networks utilize a modular, scalable architecture, enabling flexibility in deployment and management.
The architecture comprises various components, including access points, switches, and controllers, often leveraging Software-Defined Networking (SDN) principles for centralized management.
Key components often include wireless access points (APs) for wireless connectivity, wired switches for wired connectivity and a controller for centralized management and configuration.
Different network segments might be based on the functionality they provide, like guest networks, or specific departmental networks.
Network topology design considerations include factors like required bandwidth, user density, and power requirements.

Core Networking Concepts

Network topologies, such as star, bus, ring, mesh, and hybrid designs, define the physical layout and interconnections of devices.
Network protocols, like TCP/IP, ARP, and DHCP, govern data transmission and communication across the network.
Understanding routing protocols, like OSPF and BGP, enables traffic forwarding and optimization in large networks.
Network addressing schemes (IPv4/IPv6) are crucial for devices to communicate effectively with each other. Key aspects include subnet masks, IP addresses, and DNS.
Network segmentation techniques like VLANs (Virtual LANs) enable isolating different groups of users, services, or departments with specific security requirements.

Network Security Practices

Network security solutions are crucial in protecting network resources from unauthorized access and threats.
Authentication methods, including username/password, multi-factor authentication, and 802.1x, verify user identity.
Access control lists (ACLs) restrict network access based on predefined rules.
Intrusion Detection and Prevention Systems (IDS/IPS) detect and mitigate potential security threats. Firewalls are also critical for protecting network perimeters.
Data encryption protocols, like WPA2/3, secure data transmission over the network. Network security policies need to be in place to ensure a secure and controlled environment.
Regular security assessments and vulnerability scans are essential to identify and address potential weaknesses. Maintaining a secure network involves adopting and adhering to best practices, including regular patching and updates.

Troubleshooting Methodologies

Systematic troubleshooting procedures are essential for resolving network issues.
A multi-step approach, including identifying the problem, isolating the problem, testing the solution, and verifying the fix is crucial.
Utilizing various diagnostic tools (e.g., network analyzers, packet sniffers) for collecting network data and determining root causes.
Logging mechanisms help track events and identify trends in network activity.
Using network documentation such as diagrams (schematics), configuration details, and device logs enables quicker identification of the problem and finding solutions.
Employing the five WHYS to determine the root problem is essential for reliable problem-solving.

Wireless LAN Design

Designing a Wireless LAN (WLAN) involves several considerations such as the environment, user requirements, security, and performance.
Determining the optimal placement of access points (APs) takes account of factors including user density, interference, and coverage requirements.
Channel selection and frequency planning for APs minimizes interference in the wireless network.
Proper radio frequency signal strength and coverage are essential for optimal WLAN functioning and performance.
Security protocols like WPA2 and WPA3, along with authentication methods for managing access and preventing unauthorized users, are vital components of WLAN design.
Wireless standards compatibility is also a key factor in design decisions from 802.11a, 802.11b, 802.11g, 802.11n to 802.11ax (Wi-Fi 6E) or later.
Capacity planning involves determining the system's ability to meet future expansion or growth needs.
