  • Answer:

    There are various technologies involved in establishing WAN (wide area networks) links. It’s a huge topic. Simply put, there are 3 main technologies-

    1. Leased Lines - They are dedicated point-to-point connection between two remote locations. Usually the line is 'leased' from a service provider such as BSNL. Provide high speed, but is costliest.

    2. Circuit Switching- In this, in both ends, the devices are connected to the service providers switching network (such as telephone network) via modems. Think like you are making a 'data call' between two sites. Example- Dial-up connections and ISDN (integrated services digital network). This kind of link is cheaper and is used as backup for leased lines.

    3. Packet Switching- This is the hottest thing in the market. Here data is sent as small 'packets'. So it's faster, but slower than leased lines. Also cheaper, as same network is shared between other users. One example of this is MPLS (multi protocol label switching) which is now being widely used by corporate.

    Now talking about protocols (the logical part of WAN), there are various protocols for WAN such as PPP (point to point protocol), HDLC (high level data link control), ATM (asynchronous transfer mode) etc.

  • Question: What is RAID in CCNA ?

    Posted in: Cisco certification | Date: 11/09/2015

    Answer:

    RAID stands for Redundant Array of Independent Disks. In which we keep more than one disk (hard disk) for storing data. Data is continuously replicated and synced between disks. It creates a redundancy of data between the disks. So that in case of one disk failure, data can be immediately retrieved from other disks.

  • Answer:

    If the ios file is missing from router flash memory, or is corrupted; we give the command tftpdnld command from the romon mode. Before that you've to give five commands also, they’re-

    IP_ADDRESS=192.168.1.1

    IP_SUBNET_MASK=255.255.255.0

    DEFAULT_GATEWAY=192.168.1.2

    TFTP_SERVER=192.168.1.2

    TFTP_FILE=c1841-advsecurityk9-mz.124-15.T17.bin

    tftpdnld

    It'll ask for confirmation to delete all file in flash memory, press yes and hit enter.

    It'll download latest ios file from TFTP server and after completion, give command boot and hit enter.

    Here the values are given for example purpose, they may vary for your purpose.

Sir is a very good and knowledgeable teacher with excellent teaching skills. He makes sure that all difficulties and doubts are clarified and solved. He also explains the concepts well.

Shivesh Tiwari

I understood the lessons and my doubts were cleared, but it was an average experience.

Rajkumar

The classes on numerical methods was very simple and effective for solving the problems. Only suggestion is, can give importance to the derivation of equation which obviously will take more time but will be useful for understanding the theory.
