  • I have tried to write all the 65 questions I got in my exam

    Correct answers what i think are marked with a #\ YOu can rely on me on these sections.

    Routing - 100%

    Bridging & Switching - 100 %

    Cisco IOS basics & configurations - 100%

    1.What is the requirement of OSI ?

    #a. interoperatability between vendors.

    b. defines a standard for how a pc works.

    c. & d. were junk.

    2.They will give a question which contains some of the functions of the OSI

    layers like physical - does decisions on physical , mechanical chara . etc. the

    functions are marked 1,2 3. we have to arrange in order which all layers will

    map to which all functions.

    3. An enterprise server. is there. 2 domains sales & management are

    accesssing this server.. we want to have security between these 2 domains. what

    will u use.

    a & b were junk#c. use a router

    d. use a switch with access-lists applied. ( i think this is wrong- any how imarked c which i think got correct.).

    4. What is the term used , when a packet using one protocol is encapsulated

    using another protocol..... ( such as IP) ......Tunneling

  • 5. 8 PCs are connected to a switch each have 10 Mbps BW. what will be the

    individual bandwidth available to each.

    a.80

    b.20

    #c.10

    d.5

    6. What r the 2 layers of the Data Link Layer?

    LLC & MAC

    7. What r the three basic switch functions among the following.

    a & b were junk#c address learning

    #d broadcast filtering ( i marked this since it is possible withVLANS)e packet forwarding / filtering

    #f loop avoidance

    8 . 238.255.255.255 falls into which group

    Multicast

    9 what r the 2 parts of a IPX address.?

    network and node( mac ) address,

    10 ICMP & RFC 1700 is implemented in all tcp/ip hosts.

    a. true

    #b.false

    i marked false bcos what i thought was that rfc 1700 defines well known ports. &

    increases no: of collision domains, or decreases collisions, decreases size of

    collision domains.
