A rollover cable is used in a networking environment where a router/switch is to be configured from a computer. One end is wired one way but on the other it is reversed. You would typically use one end into a serial port on a PC and the other into the console port of the switch/router. It is common within cisco configurations.

What are three main safety features of an F1 car?
Formula One racing is considered one of the most dangerous sports for drivers because of the high speeds and challenging courses. Many of the rules in Formula One racing are designed with driver safety in mind and constructors are always looking at new design features to enhance driver safety. Formula One racing rules require that a driver must be able to get out of the racecar quickly. The exit must be accomplished in less than five seconds with the removal of nothing more than the steering wheel. According to FIA rules the steering wheel must also be able to be re-installed within five seconds to allow for quick removal of a car from the track to insure the safety of other Formula One racing drivers. The cockpit area of a Formula One racing car is referred to as the survival cell. In Formula One racing, the survival cell is equipped with a rollover protection hoop as well as front and rear crash protection features. Recent changes have focused on making side walls taller and stronger to protect the driver's head from flying debris. Formula One racing cars are put through crash tests to determine their ability to safely protect the driver. Although fires are rare in Formula One racing today, fire safety precautions are still an important part of driver safety. The clothing worn by race drivers are made from fireproof materials designed to protect the driver in case of fire until it can be extinguished. Design of the clothing must also take into account the extreme conditions that Formula One racing drivers face during a race. During a race drivers must endure extremely high temperatures inside the care and must wear items that allow sweat to escape to avoid overheating. Specially designed fabric that meets both the fireproof and wear-ability factors is used for everything, including the thread and sponsor patches on the uniform as well as the underwear worn by the driver. The shoulders on overalls worn by Formula One racing drivers have to large safety handles. Because FIA rules require that a driver be removed quickly from his car while strapped into the seat they are held in place with only two standardized bolts that can be removed with a tool carried by every rescue team. The long and strong straps make it possible to remove both driver and seat together. Helmets play a key role in Formula One racing safety. It is important that helmets be as lightweight as possible since added weight increases the severity of whiplash during a crash. Today's Formula One racing helmets weigh just under three pounds. The helmet is comprised of layers made of carbon fiber, a plastic like that used in bulletproof vests, a softer plastic and a covering of flameproof material. Visors are composed of a polycarbonate. The leading causes of death in auto racing accidents are skull and neck fractures resulting from rapid deceleration during accidents. The Head and Neck Support system (HANS) was designed to reduce these whiplash effects. The system consists of a collar that is attached to the safety belt and strapped to the helmet to hold the helmet in place during an accident. HANS usage became mandatory in Formula One racing in 2003. Injuries and accidents are unavoidable. Formula One racing sets high standards for medical care at each Grand Prix. Trained medical and extraction teams are in place at each race, each circuit has a fully equipped medical center and local hospitals are on standby during races. * http://www.carsaddiction.info/formula-one/security-first-drivers-safety-in-f-1.html

Why would one choose to use a Cisco VPN?
A Cisco VPN is a Virtual Private Network and used to extend a private network over a wider public network. One might use such a network from Cisco to access a private network from a remote location.
Whenever a screen needs redrawing (e.g., upon creation, resizing, validating) the update method is called. By default, the update method clears the screen and then calls the paint method, which normally contains all the drawing code.
What is the purpose of routers?
Routers are responsible for delivering and receiving network communication. They regulate what goes in from either "leg" of the router and what goes out of either "leg". They can also be configured to send specific data through specific routes, hence the name.
The purpose of routers is to take the signal that is being sent via the cable wire and convert it into a wireless signal that multiple devices can connect to.
The Cisco Certified Internetwork Expert, or CCIE, is a technical certification offered by Cisco Systems. The CCIE certifies the skills required of network engineers to plan, operate and troubleshoot complex, converged network infrastructures on a wide variety of Cisco equipment.
The CCIE is described by Cisco as "the most prestigious networking certification in the industry." The CCIE certifies a very specific set of skills in the field of networking. According to Cisco, less than 3% of Cisco Certified engineers obtain CCIE certification and less than 1% of the networking professionals worldwide, and the average candidate will spend thousands of their own dollars and spend at least 18 months studying while pursuing it. Passing all the requirements of the program earns the individual a unique CCIE number assigned by Cisco.
The program is currently divided into seven different areas of expertise or "tracks". The CCIE track in which one becomes certified determines the different aspects of networking technology that individual is recognized as being an expert in. One may also choose to pursue multiple CCIE tracks to be recognized as an expert in several different categories of Cisco technology: Routing & Switching, Service Provider, Security, Service Provider Operations, Voice/Collaboration, Data Center, and Wireless.

What statement describes the purpose of a default route?
A host uses a default route to transfer data to a host outside the local network when no other route to the destination exists.
You may configure the gateway of last resort to achieve this functionality especially if there is a need to route packets outside the LAN.
The way to configure a default route to a Cisco Layer 3 device is as follows:
Router(config)# ip route <network-address> <subnet-mask> <next-hop-address>
Example: Router(config)# ip route 0.0.0.0 0.0.0.0 172.18.3.1
