C.BGP route-reflector will stop reflecting the routes if they’re not directly-connected clients.
D.None of the above.
Correct Answers: B
6: Which 4 statements regarding MPLS Label Stack Encoding is true?
A.A value of 4 represents the “Implicit NULL Label.”
B.A value of 0 represents the “IPv4 Explicit NULL Label.”

E.A value of 1 represents the “IPv1 Explicit NULL Label”
F.A value of 3 represents the “Implicit NULL Label”
Correct Answers: B C D F

13: The layer 2 protocol used by POS technology offers a standarized way for mapping IP packets into SONET/SDH payloads. Select the correct sequence of POS operation.
1) Data is scrambled and synchronous mapping takes place by octet into the SONET/SDH frame.
2) Encapsulated via Point-to-Point Protocol (PPP) takes place framing information is added with High-level Data Link Control (HDLC).
3) Gaps between frames are filled with flags, set to value 7E.
4) Octet stuffing occurs if any flags or resultant escape characters (of value 7D) are found in the data.
5) Data is segmented into an IP datagram with its 20-byte IP header.

E.5,2,3,1,4
Correct Answers: D
14: Which two statemets are true?
A.DPT/RPR uses a bi-directional ring consisting of two symmetric counter rotating fibre rings.
B.DPT/RPR is defined in the IEEE 802.17 standard and it uses Token Bucket system to avoid collisions on the fiber.
C.In DPT/RPR rings, data packets can be sent in one direction (downstream) and the corresponding control packets in the opposite direction (upstream), thus using both fibres concurrently to maximise bandwidth.
D.DPT/RPR can be deployed in the Core of the SP networks where point-to-point POS links are used to make best use of the Bandwidth.
