   1. A1-512
   2. B64512-65535
   3. C512-65535
   4. D1-64511
   5. E63488-65535
2. 2BGP Basic - For a 4 bytes AS number type, what is the range of private AS number ( other than the regular 2 bytes ASN private range )
   

   1. A4200000000 - 4294967294 ( 64086.59904 - 65535.65534 )
   2. BThere is no other private range.
   3. C4100000000 - 4294967294 ( 61086.59904 - 64086.59904 )
3. 3BGP Basic - From the following output, wich prefix learned have been add to the the BGP Table with the network Command.

   

   1. A112.0.0.0
   2. B150.1.1.1/32
   3. C155.1.0.0/24
   4. D169.254.100.0/24
4. 4BGP Basic - How is the compatibility between BGP router using 4 byte ASN notation and BGP Router that support only 2 Byte AS notation.

   1. AThe 2 bytes ASN router will not accept to form a peering with a 4 byte AS number.
   2. BThe 4 bytes ASN router need to have a secondary ASN number wich is 2 byte long
   3. CThe 4 Byte ASN router will use the ASN 23456 as his AS number when it will peer with a 2 bytes only ASN router.
   4. DThe 2 bytes router will use the last two octet of his peer AS number wich may prevent prefix from being advertised to an other 4 bytes AS wich have the same las two octet.
5. 5What is the BGP command to change the ASN notation to a Dot notation? (config-router)#[blank_start]bgp asnotation dot[blank_end]

   1. Abgp asnotation dot

   5. EAS_Path
7. 7iBGP Route-Reflector - Name two BGP attribute added only by the Route-Reflector to avoid routing loops:
   

   1. AOriginator ID
   2. BCluster-list
   3. CRoute-Reflector ID
   4. DReflector sequence
8. 8iBGP Route-Reflector - Name three type of peers that a Route-Reflector can have.

   1. AEBGP peers
   2. Bclient peers
   3. Cnon-client peers
   4. DRR peers
   5. ECluster peers
9. 9INCOMPLETE - iBGP Route Reflector - Is the following configuration for a iBGP Route Reflector Client is valid:
   
   Output...
   

   1. ATrue
   2. BFalse
10. 10iBGP - What happen when two BGP Routers in the same network have the same Router-ID

    1. AThe client will not accept route with the same Originator-ID as it Router so it will drop route advertised by another router with the same router-ID
    2. BRouter reflector will detect this miss configuration and will not form a bgp peering with the most recent peer with the same router-id as an already established peer.

11. 11INCOMPLETE - BGP Route-Reflector - Identify wich statement is False :

    1. ARoutes learned from EBGP peers can be sent to other EBGP peers, clients, and non-clients.
    2. BRoutes learned from client peers can be sent to EBGP peers, other client peers, and non-clients.
    3. CRoutes learned from non-client peers can be sent to EBGP peers, and client peers, but not other non-clients.
    4. DFalse!!!
12. 12BGP Basic - Place the BGP attribute in the correct order they are process in the BGP Best Path Algoritme:
    1 - [blank_start]Weight[blank_end]
    2 - [blank_start]Local Pref[blank_end]
    3 - [blank_start]Locally Originated[blank_end]
    4 - [blank_start]AS_PATH[blank_end]
    5 - [blank_start]Origine ( Lowest, IGP < EGP < ? )[blank_end]
    6 - [blank_start]multi-exit discriminator (MED)[blank_end]
    7 - [blank_start]Neighbor type (eBGP over iBGP)[blank_end]
    8 - [blank_start]IGP metric (lowest metric to Next-Hop)[blank_end]

    1. ALocal Pref
    2. BWeight
    3. CLocally Originated
    4. DAS_PATH
    5. EOrigine ( Lowest, IGP < EGP < ? )
    6. Fmulti-exit discriminator (MED)
    7. GNeighbor type (eBGP over iBGP)
    8. HIGP metric (lowest metric to Next-Hop)

19. 19RFC 4271 - Select three methods by which a given BGP speaker can indicate
    that a route has been withdrawn from service.

    1. AThe IP prefix that expresses the destination for a previously
       advertised route can be advertised in the WITHDRAWN ROUTES
       field in the UPDATE message
    2. BA replacement route with the same NLRI can be advertised
    3. CThe BGP speaker connection can be closed
    4. DThe BGP speaker send a route_refresh message to trigger an update to his peer.
20. 20RFC 4217 - How a BGP speaker change attribues of route advertise to his peers.

    1. AThe BGP Speaker advertise a replacement route with the same NLRI but new attributes in a Update message.
    2. BThe BGP Speaker send an Update message containing the prefix with the old attribute in the Withdrawn routes and the new attributes with the same prefix.
    3. CThe BGP Speaker send an Update message containing the prefix with the old attribute in the Withdrawn routes.
       After the update message with the withdrawn routes, the BGP Speaker send an other update message with the same prefix and the new attributes.
