For all CCIEs you need to pass a 3 hour written (online) exam of around 100 questions on Cisco technologies. Once you have passed this you have 18 months to pass the associated lab exam, which takes 8 hours.
TO recertify you need to pass the CCIE written exam.
How do you reduce network congestion?
There are several ways to reduce network congestion. Subnetting and adding routers will break up broadcast domains and traffic. Adding VLANs will do the same while adding security. Upgrading the speed of NICs and wiring, i.e. moving from 10BaseT to 100 or 1000, will reduce congerstion as will moving from half duplex transmissions to full duplex transmissions.
What cat Ethernet cable is the best?
The best Ethernet cable is CAT-6 (UTP), if you have enough money you can get STP for better performance and stability.
Is a Ethernet box the same as a router?
No, they are not the same. A router can connect several Ethernet networks together. Ethernet is the name of a layer 2 protocol.
to allow for transmission on two separate LANs at the same time.
Perhaps the most common application of dual Ethernet is in firewall machines.
How do you host a Halo CE server with your foreign IP address not your local 192 one?
Most routers (even home routers) have a feature known as port forwarding; you set the ports for Halo to forward to your 192 based server. The net result is that external users are routed to your server by using an external IP address and don't know that this is happening.
For example, if a game or an application uses port 5000 to communicate with the server, set port 5000 to the 192.168 address of your server. If your external IP address for the router is (for example) 31.44.55.66, then users can get to your server by using the 31 address, but packets for the game will be routed to your 192.168 server which is internal.
You must be taking Cabling at ITT Tech...
You can find the answer in your text book (Cabling: The Complete Guide to Copper and Fiber-Optic Networking) Fourth Edition: Andrew Oliviero / Bill Woodward.
It is on page 8, top paragraph. The IEEE maintains the industry standards for Ethernet Protocols (or applications). This is part of the 802.3 series of standards and includes applications such as 1000Base-T, 1000Base-SX, 10GBase-T, and 10GBase-SR.
What is also known as gigabit Ethernet?
Gigabit Ethernet is also known as 1000 mega bits per seconds (Mbps). It is a part of the family of Ethernet computer networking and communication standards.
Why can't you use a straight through cable to connect a computers NIC to a router's Ethernet port?
A straight cable is used to connect a PC to a hub, switch, or router.
Where does the Ethernet cable go on the desktop?
Your Ethernet cable should have an RJ-45 modular connector on each end of the cable. Connect one plug in the RJ-45 slot/connector in the back of the desktop unit, and connect the other end to a switch, hub, or router.
Is 15m too long for an cat5e Ethernet cable will it affect performance?
No, the standard Ethernet cables can have up to 100 meters.
No, the standard Ethernet cables can have up to 100 meters.
No, the standard Ethernet cables can have up to 100 meters.
No, the standard Ethernet cables can have up to 100 meters.

What is the difference between industrial ethernet and normal ethernet?
There is no difference; Ethernet is Ethernet, regardless of where it is deployed.
How is the network infrastructure built for manufacturers?
Networks are places with online services for personal accounts that are signed up.
These networks has unlimited space for IDs, think of it as a infinite world full of IDs floating around filled with online information in each personal ID, there are millions and millions of personal accounts in the online networks. Each of the networks are dedicated, every manufacturer (Microsoft, Sony, Nintendo, Apple ;etc) has its own dedicated online network. Every network has a certain infrastructure of online services but the storage for IDs and data inside the IDs is unlimited and same kind of storage for every network. Each ID for networks are personal and shouldn't be shared, even by just two people.
What are the characteristics of gigabit Ethernet?
data can be transferred at a maximum rate of 1000 Mbps
data transmission can be via UTP or fiber optic cabling
Short for Registered Jack-45, an eight-wire connector used commonly to connect computers onto a local-area networks (LAN), especially Ethernets. RJ-45 connectors look similar to the ubiquitous RJ-11 connectors used for connecting telephone equipment, but they are somewhat wider.
A router is a device that acts as connection between two different networks. In this case, the cable company has one network, which includes your Internet Connection. The network is your home computer or computers. The cable router allows these two networks to connect with each other and share information.
Is it ok to use 100 feet of cat 6 cable?
Yes - the maximum segment length is usually 100 meters, or 330 feet.
