  1. How are traditional and SD networks different?

  2. what is the overlay, underlay design principle?

  3. What is the redundancy design principle?

  4. what are the 4 different types of operational planes in SDWAN? What does each one do

    MCDP

  5. what is a chasis switch?

    A chassis switch enables users to plug modules directly into the switch. Each module is a certain type of network device. One module might be a 16-port 100Base-T hub, another might be a router, whereas another might be a 4-port 100Base-T switch, and so on. The switch is designed to hold a certain number of modules and has a certain internal capacity, so that all the modules can be active at one time. For example, a switch with five 10Base-T hubs, two 10Base-T switches (with 8 ports each), a 100…

  6. what are the components of a chassis switch?

    Modules - can be anything: router or switch Back plane - circuitry which enables data transfer Eg: 6520 Chassis Switch 8 modules with 1 GBps back plane

  7. What are the three different types of common underlay n/w designs?

    N/W in a box - 200 -300 points 2000 points 10000 end points

  8. Draw he design of a 2000 endpoint system. Discuss the components used

  9. What makes up overlay architecture?

  10. Wha are the two types of tokens used by vlan?

  11. What is the main difference between a traditional n/w and sdwan when it comes to subnets?

  12. what are the two ways in which sdwan n/w in a campus is connected to other n/w?

    Internet Edge -> Backbonw has module connected to ISP of Internet WAN Edge -> Backbone has module connected to POP in common carrier

  13. what is an example where both the connections are used?

    Branch campus: has no core router backbone switch1 connected to ISP backbone switch2 connected to POP

  14. Who are the three different types of cybersec perpetrators?

    physical security wireless LAN security internet security

  18. how does a firewall work?

    using Traffic filter like : Access control lists ACL - re db > permit source address -> dest address -> destination port benefit: can block any hacker from outside based on source address even if they have access to credentials

  19. how does a distributed denial of service attack work?

    need 100,000 devices to effectively carry out a ddos attack: spread virus to control device launch when have enough device

  20. how to protect against DDOS?

    contract with the common carrier get alerted when observe too much traffic being directed to a particular server divert DDoS traffic to scrubber

  21. how is workforce security implemented?

    Passwords long passwords sso - so that you don't have to remember multiple passwords Mulit factor authentication DUO

  22. what is a common threat to workforce security?

    phishing attacks: pretend to be someone to steel login credentials

  23. how is workplace security implemented?

    give company devices for company related work can track activity desktop management enforce system updates control access

  24. what are the 3 areas of focus for workload security?

    data if you use cloud storage, you need to have backup of all data apps implement 3 tier thin architecture: client ->app server-> db where firewall secures the connection to the db traffic use IPS to monitor, alert and block malicious traffic
