- Encryption – TKIP and AES.
- Configuring the Wireless Access Point
- Configuring security: personal and enterprise (AAA and EAP ).
- WLAN Troubleshooting: Incorrect Channel Settings, Solving RF Interference, Access Point Misplacement and Authentication and Encryption
LAN Switching and Wireless: Ch2 - Basic Switch Concepts and ConfigurationAbdelkhalik Mosa
This chapter starts with discussing the key elements of ethernet/802.3 networks such as CSMA/CD, communication using unicast, multicast, and broadcast, the ethernet frame, MAC address, duplex settings, half-duplex and full-duplex, switch port settings, auto-MDIX, and the switch MAC table.
After that, there is a discussion about the design considerations for Ethernet networks such as bandwidth, throughput, goodput, collision domains, broadcast domains, LAN segmentation, and network latency.
Switch forwarding modes: store and forward and cut-through and the difference between symmetric and asymmetric switching.
Memory Buffering: port-based memory and shared memory.
The difference between layer 3 switches and routers.
Cisco switch CLI commands, accessing the history, switch boot sequence and recovering from system crash.
Managing the MAC address table, dynamic MAC addresses and static MAC addresses and backing configuration files to a TFTP server.
Configuring switch passwords and password recovery, configuring telnet and SSH.
Common Security Attacks such as MAC address flooding, spoofing attacks, CDP attacks and telnet attacks.
Switch port security, sticky port security and security violation modes: protect, restrict and shutdown and verifying poert security
Switching: means receiving data on a certain port and forwarding it to appropriate port transparently, just care about the next hop, so it is a layer 2 action.
Examples of Layer 2 devices: NIC, Bridge and Switch.
Hierarchical network design with access, distribution and core layers.
The benefits of the hierarchical network design.
Understanding hierarchical network design principles such as network diameter, bandwidth aggregation and redundancy.
The definition converged network.
Understanding different switch features:
1. Form Factors (Fixed, Modular and Stackable)
2. Performance (Port Density)
3. Performance (Forwarding Rates & Link Aggregation)
4. Power over Ethernet
5. L3 Functions
Access Layer Switch Features.
Distribution Layer Switch Features.
Core Layer Switch Features
Features of Cisco Catalyst Switches
LAN Switching and Wireless: Ch4 - VLAN Trunking Protocol (VTP)Abdelkhalik Mosa
This chapter discusses in detail the VLAN Trunking Protocol (VTP). How the VTP manages the consistency of VLAN configurations? Understanding the different components of the VTP: VTP domain, VTP Advertisements and the different VTP Modes. A switch can be configured in one of three modes: server, client, or transparent.
VTP pruning and the anatomy of VTP advertisements. The different types of VTP advertisements: summary advertisement, subset advertisement and request advertisement. This is followed by showing VTP in action.
Finally, the VTP configuration and the troubleshooting of common VTP connections problems such as incompatible VTP versions, incorrect VTP domain name and the incorrect revision number.

Module name is Networks 512
As the demand for faster and more efficient high-performance computers grows, so do the
dimensions of the form factors that house them. Computer engineers have been tasked for years
with the difficult task of incorporating increasingly powerful computers into and onto
increasingly smaller chassis and printed circuit boards (PCBs), primarily to meet a growing
demand for more reliable, affordable, size-conscious, energy-efficient, and cost-effective
computer systems. This is why the world of embedded systems continues to see boundary-
pushing size, weight, power, and cost developments. 2.1 Use your knowledge of embedded
systems and devices to answer the question below. 2.1.1 What are embedded systems? 2.1.2
What are the various kinds of embedded systems? 2.1.3 What is the difference between soft and
hard real-time embedded systems?
device may require on both the serial and network sides of a connection. Should the device
always be connected to a specific host or PC? Is it possible that multiple hosts or network
devices will want or need to connect to the newly networked serial device? Are there any
specific requirements for an application that requires the serial device to reject a network
connection under certain conditions? The bottom line is that a server must be able to service a
wide range of application requirements while also meeting all of the demands of those
applications. Discuss how device servers are used to improve the usability of various
applications such as: Data Collection, Factory/Industrial Automation, Security Systems, Bar
Code Readers and Point-of-Sale Scanners, Medical Applications, M2M Wireless
Communication/Networking. (30)
1. An extensive telecommunications infrastructure is provided by a structured cabling system,
which is a complete system of cabling and related components. This infrastructure is used for a
variety of purposes, including phone service provision and data transmission across computer
networks. It shouldn't be hardware-reliant. A structured cabling system is further defined in
terms of ownership. At the termination of the service provider (SP), the structured cabling
system starts. The demarcation point (demarc) or network interface device is at this location
(NID). For instance, in the establishment of a telephone system, the SP provides one or more
service lines (per customer requirements). At the line of demarcation, the SP joins the service
lines. 1.1 Explain the significance of structured cabling and the advantages of structured cabling.
(10) 1.2 As a network architecture, you are tasked with designing a network for a six-story office
building, with each floor connecting 5 computers in 5 offices and having a wireless access point
to connect wireless devices. Design a network plan for the building using your knowledge of
structured cabling and various network devices, labeling all the hardware in devices and cabling.
