Cisco Related by MindLeaders BCRAN 642-821
The ability to work efficiently and effectively from a remote location, whether it's a branch office, small office/home office (SOHO), or a mobile location, is critical. Similarly, understanding how the available technologies interact and determining how to best manage them are key components of any professional's skill set. This course presents the methodologies involved with configuring remote access. It describes IOS options and hardware products for securing a network and defines ways to make securing the network easier. Other topics discussed include virtual private network (VPN) capabilities, integration with intrusion detection system (IDS) sensors, and the firewall feature set.
This series is for anyone preparing for the Cisco BCRAN 642-821 exam or for anyone who wants to learn more about networking. This online course contains 8 lessons and 1 practice exams and should take approximately 13 hours to complete.
WAN Technologies, Components, and AAA Security
This course presents the methodologies involved with configuring remote access The ability to work efficiently and effectively from a remote location?whether it's a branch office, small office/home office (SOHO), or a mobile location?is critical to virtually every industry and company Knowing what technologies are available, how they can interact, and how to manage those technologies is a key component of any professional's skill set The second part of the course describes IOS options and hardware products to help secure a network and make securing the network easier, such as virtual private network (VPN) capabilities and integration with intrusion detection system (IDS) sensors and the firewall feature set and teaches you how to select appropriate hardware, determine bandwidth requirements, select a WAN connection and a backup connection, choose and Configure WAN encapsulations, start the AAA process on a router, configure AAA addresses and passwords, enable authentication, authorization, and accounting, and understand the AAA commands.
PPP Authentication and Network Address Translation
This course covers the login process using PPP Today's corporate environments contain more telecommuters than ever before As a result, dial-in access is an important part of network connectivity The course also describes how NAT provides the ability to convert one address to another One of the biggest challenges in networking is addressing, and the challenge only becomes bigger as networks scale and grow connected NAT offers great flexibility in the use of addresses and teaches you how to configure and troubleshoot PPP, describe link quality monitoring, analyze debug output, configure static and dynamic NAT, configure overloaded and overlapped NAT, and understand how to verify and troubleshoot NAT.
Modems and Asynchronous Connections
This course describes how to correctly choose and deploy the proper cabling and master the configuration of the router, its resources, and modems attached to the router Asynchronous connections via modem are an integral part of any wide-area network (WAN) implementation Although it has been relegated to backup status in most cases, the asynchronous connection still has many advantages, including its ready availability and low cost and teaches you how to configure an asynchronous line, select the proper cables and adapters, set up modem autoconfiguration, configure modems manually, maintain the modemcap database, and debug modem autoconfiguration.
Using ISDN Connections
This course covers the two forms of Integrated Services Digital Network (ISDN): Basic Rate Interface (BRI) and Primary Rate Interface (PRI) ISDN usage, equipment and call progress, are discussed prior to a detailed description of BRI and PRI configuration and teaches you how to understand the relationship of ISDN components, describe call setup and teardown, configure an ISDN interface, and troubleshoot an ISDN configuration.
Using Frame Relay Connections
This course covers the concepts, components, and use of Frame Relay Frame Relay is a standard supported by both the American National Standards Institute (ANSI) and the International Telecommunication Union that defines the encapsulation from the customer premises equipment (CPE) to the data circuit-terminating equipment (DCE) at the regional provider's switch Frame Relay configuration, traffic shaping, fragmentation, and troubleshooting are presented and teaches you how to determine correct line speeds, configure interfaces for Frame Relay, monitor Frame Relay operation, and troubleshoot Frame Relay operation.
Dial-on-Demand and Broadband
This course covers the DDR process by which a link is created on demand As traffic needs to cross the WAN, a circuit is completed from the source router to the destination, allowing the traffic to cross DDR circuits are useful when you pay for access based on the amount of time the circuit remains up The second part of this course examines broadband technologies A cursory look at direct broadcast satellite (DBS) and fixed wireless providers is followed by more on cable modems Four wireless segments: local multipoint distribution service (LMDS); multichannel multipoint distribution service (MMDS); industrial, scientific, and medical (ISM); and unlicensed national information infrastructure (U-NII) bands are also presented and teaches you how to understand DDR (dial-on-demand routing), articulate dialer profiles and interface, describe broadband, cable modems, and DSL, describe a cable modem infrastructure, identify different DSL types, describe ADSL, PPPoE and PPPoA, configure PPPoE and PPPoA, and troubleshoot DSL configurations.
Enabling Backup Connections and Management of Traffic
This course covers the use of dial backup to back up a permanent connection Having a second connection that can move data in the event the primary connection fails is a wise move for today's corporate environment This course also covers the use of each of the three types of queuing (WFQ, PQ, and CQ), how to configure the router for each type, and the potential pitfalls of each The Link, Payload, Header, and Modem data compression types are presented and teaches you how to use the backup load command, determine routing protocol preferences, calculate backup delay, describe basic queuing, compare advanced queuing techniques, articulate traffic importance, and describe compression types.
Securing the Network with VPNs
This course covers VPN and IPSec terminology, design, configuration, testing, and verification The key to the popularity of VPNs is that companies can replace traditionally high-priced dedicated WAN connections for a fraction of the cost with VPN and teaches you how to define VPN and list its advantages, describe tunneling and encryption, identify different VPN scenarios and solutions, articulate the five steps of IPSec, describe how IKE works, design and configure IKE and IPSec, and test and verify IPSec.
Practice Exam
This course provides two practice exams for the Cisco BCRAN 642-821 certification exam.
