1. What is the name of the Safe Work Australia code of practise that provides guidance on how to manage the risks of electrical equipment in the workplace?2. In the code of practise referred to in question 1 (hint: there is a download link in the link 1 article that enables you to download and review the code of practise) what are the four steps of the risk management process?3. What are two things you can do to manage risks associated with electrical equipment in the workplace (see section 3 of the code of practise)?4. What does MPLS use instead of a destination IP address to forward data between routers across an MPLS network?5. True or False? MPLS only works with IP networks.6. What is the major function of Label Edge Router (LER) in an MPLS network?7. What is the major function of a Label Switching Router (LER) in an MPLS network?8. What is the definition of a Label Switched Path (LSP) in an MPLS network?9. What are the names of the three operations (corresponding to add a tag, remove a tag, and exchanging one tag for another) a router can perform on a tag in an MPLS network? 10. True or false? Traffic engineering in MPLS sometimes means a longer (i.e. more hops) data path can be preferred to a shorter one.11. Give one example of a technology that could be used to implement a point-to-point WAN link between two devices.12. List the four steps a network engineer could use to implement a point-to-point WAN link13. Give two examples of equipment that would typically be defined as Customer Premises Equipment (CPE)14. Why is clocking usually necessary over serial links?15. List three organisations who are active in defining and publishing WAN-related standards.16. What is meant by "path selection" as it applies to routers?17. List three different types of hardware that a router would typically have.18. What information is typically stored in the RAM of a router?19. Where is the router backup/startup configuration usually stored?20. What information is stored on the flash memory of a router?21. For what reason would a router have multiple power supplies?22. If I want to connect to a router console port from a PC, what port do I use on the PC and what type of Cisco cable do I need to use?23. What is meant by "out-of-band" management as it applies to Cisco routers? 24. What port(s) on a router would I typically use for out-of-band management of routers?25. Give a brief example of a situation where a network engineer would need to use out-of-band management for a router.
