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.
A.1,2,3,4,5
B.1,3,4,5,2
C.2,3,5,4,1
D.5,2,3,4,1
E.5,2,3,1,4
Correct: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.
Correct:A C

15.Which of the following IOS commands cause syslog messages to be stamped with time and dates?
A.service timestamps log datetime
B.logging trap datetime
C.service logging datetime
D.logging datetime on
E.logging timestamps on
Correct:A

16.The OSPF External LSA for prefix x.x.x.x exists in the OSPF database, but the prefix is not installed in the routing table. Which are possible explanations?
A.Inbound distribute-list is configured under the ospf process and it is denying x.x.x.x
B.ASBR origination the LSA is not reachable.
C.Route to the Forwarding Address in not an internal OSPF route.
D.Route to the Forwarding Address is an internal OSPF route.
E.Route to the ASBR does not follow the same path as the one to the Forwarding Address.
Correct:A B C

17.What is the action of “pop” in the context of MPLS switching?
A.It removes the top label in the MPLS label stack.
B.It adds a top label in MPLS label stack.
C.It replaces the top label in the MPLS label stack with another value.
D.It replaces the top label in the MPLS label stack with a set of labels.
E.None of above.
Correct:A

18.What are the differences between LLQ and CBWFQ? (Choose two.)
A.LLQ supports the addition of strict priority queuing.
B.With LLQ, bandwidth allocations for the priority queue and all the CBWFQ queues are configured using the priority command.
C.LLQ is configured using MQC and CBWFQ is configured using the fair-queue command.
D.LLQ priority queue bandwidth is policed with a congestion aware policer.
E.LLQ does not support WFQ on the default traffic class (class-default).
Correct:A D

19.Which command will display the MPLS label binding for IP prefix 1.1.1.0 on the router?
A.show tag-switching tdp binding 1.1.1.0/24
B.show tag-switching tdp bindings neighbor 1.1.1.0
C.show tag-switching interface e0/0
D.A and B both will show the binding.
E.All of the above.
Correct:A

20.Which two statements are true about RPF checks in MSDP(Multicast Source Discovery Protocol)?
A.It prevents message looping, Session Advertisement (SA) messages must be RPF checked.
B.RPF check should be done against the route to the source S of the corresponding PIM-SM domain.
C.RPF check should be done against the route to the Rendez-vous Point of the corresponding PIM-SM domain, which originated the SA.
D.RPF checking Session Advertisement (SA) messages will cause message looping.
Correct:A C
