November 17‚ 2008 Backup and Recovery 1. Describe the four-step process to locate and load the IOS. The four step process to locate and load the Internetwork Operating System‚ or IOS‚ is known as the boot sequence. These are the steps that a router must follow in order to bring the device into an operational status. The first step is known as POST. POST is a ROM based program that runs whenever the device is booted up. This is where the hardware will get checked to ensure they are “operational

Checkpoint: Signals Adam Kurylo IT/242 3/8/2012 Voice Signal Technology- Commonly referred to voice over IP‚ or VoIP‚ involves the delivery of voice services over the internet. Voice travels in packets over IP networks with fixed maximum compacity. The technology uses protocols that deal with the data link and the physical layer‚ and use quality of service mechanisms to ensure the technology works well even in congested scenarios. Some of those technologies are; IEEE 802.11e- which defines

Initially‚ suppose there is no physical link between AS2 and AS4. * Router 3c learns about subnet with prefix x from which routing protocol: OSPF‚ RIP‚ eBGP‚ or iBGP? eBGP * Router 1d learns about subnet with prefix x from which routing protocol? iBGP * Once router 1d learns about x it will put an entry (x‚I) in its forwarding table. Will I be l1 or l2 for this entry? Explain your answer briefly. I1‚ the interface

As a network administrator for a company‚ you want to configure an IP route between two routers. Of static and dynamic routing‚ which is more appropriate? Explain your answer in 200 to 300 words. I think that the best routing choice for this would be a static IP; this is because for a company you may want to have the ability to check the log for problems. Using a dynamic IP would mean that the people that logged on to their device would be almost invisible because they could

P.O.W. #2 The Big Knight Switch Problem Statement One day 2 white chess knights and 2 black chess knights were on a chess board‚ which is 3x3 squares. The knights decided to try to switch places‚ like the white knights would end up where the black knights started out and the black knights would end up where the white knights started out. The rules are: Each ‘move’ consists of two squares in 1 direction and then 1 square in a perpendicular direction. They have to stay within the nine squares

There is no true defining evidence that can explain our actions when we are alone and when we are with a group of people. The only thing we have to offer are theories and technical research that can really support what triggers a hive switch. There are several reasons
