Following questions and answers are all new published by Cisco Official Exam Center: QUESTION 381What is also called Type 0 authentication in OSPF on Cisco Routers? A.    MD5B.    There is no Type 0 authenticationC.    SHA1D.    NullAnswer: DExplanation:These are the three different types of authentication supported by OSPF. Null Authentication--This is also called Type 0 and it means no authentication information is included in the packet header. It is the default.Plain Text Authentication--This is also called Type 1 and it uses simple clear-text passwords. MD5 Authentication--This is also called Type 2 and it uses MD5 cryptographic passwords. QUESTION 382Refer to the exhibit. Which two statements are correct, when the QoS configuration is applied in an outbound direction on a 10-Mb/s interface? (Choose two.)   A.    When reaching 10 Mb/s of input rate, the video class will be policed to 200 kb/s.B.    The class FTP is allowed to reach more than 1 Mb/s in the event of congestion.C.    IP precedence 1 traffic is affected by a drop probability.D.    Video traffic above 200 kb/s is allowed to pass when the total interface output rate does not reach 10 Mb/s.E.    Video traffic above 200 kb/s is allowed to pass when congestion is present. Answer: BDExplanation: QUESTION 383Refer to the exhibit. A user with IP address fails to use Telnet to a switch with IP address is most likely the issue?   A.    The switch is not configured with a default gateway.B.    The HTTP server is not enabled on the switch.C.    STP is blocking the connection from switch to router.D.    IP routing is enabled on the switch, but no route pointing back to the client is configured.E.    The switch is configured with an IP address from the wrong subnet. Answer: DExplanation:As you can see in the exhibit that IP routing is enabled on the switch but no route is pointing back to the client. The ip address of interface vlan 1 is given but after that nothing! QUESTION 384Refer to the exhibit. Router RTB is performing one-way redistribution from RIP to OSPF. Which outgoing interface will router RTD choose for packets to the network, and why?   A.    Fa0/1, because OSPF is a link-state routing protocolB.    Fa0/0, because RIP is a distance vector protocolC.    Fa0/0, because RIP has a higher administrative distanceD.    Fa0/0, because OSPF has a lower administrative distanceE.    Fa0/1, because OSPF has a lower administrative distanceF.    Fa0/1, because RIP has a lower administrative distance Answer: E QUESTION 385Refer to the exhibit. What is the potential issue with this configuration?   A.    There is no potential issue; OSPF will work fine in any condition.B.    Sub-optimal routing may occur since there is no area 1 adjacency between the ABRs.C.    This is a wrong OSPF configuration because all routers must be in area 0 only.D.    This is a wrong OSPF configuration because /30 requires wild card. Answer: BExplanation:The primary difference is that the GRE tunnel hides the real recipients under the outer IP header. The "transit" area, in that case, does not need to actually know all the prefixes. What it needs, though, is a default route that points towards the backbone. Suboptimal routing may occur, then, because the traffic from the "transit" area must first reach the backbone in order to get GRE- encapsulated and carried again through the "transit" area to the disconnected area. QUESTION 386Refer to the exhibit. What triggered the first SPF recalculation? A.    changes in a router LSA, subnet LSA, and external LSAB.    changes in a router LSA, summary network LSA, and external LSAC.    changes in a router LSA, summary network LSA, and summary ASBR LSAD.    changes in a router LSA, summary ASBR LSA, and external LSA Answer: BExplanation:OSPFv2 is built around links, and any IP prefix change in an area will trigger a full SPF. It advertises IP information in Router and Network LSAs. The routers thus, advertise both the IP prefix information (or the connected subnet information) and topology information in the same LSAs. This implies that if an IP address attached to an interface changes, OSPF routers would have to originate a Router LSA or a Network LSA, which btw also carries the topology information. This would trigger a full SPF on all routers in that area, since the same LSAs are flooded to convey topological change information. This can be an issue with an access router or the one sitting at the edge, since many stub links can change regularly.Only changes in interarea, external and NSSA routes result in partial SPF calculation (since type 3, 4, 5 and 7 LSAs only advertise IP prefix information) and thus IS-IS's PRC is more pervasive than OSPF's partial SPF.This difference allows IS-IS to be more tolerant of larger single area domains whereas OSPF forces hierarchical designs for relatively smaller networks. However with the route leaking from L2 to L1 incorporated into IS-IS the apparent motivation for keeping large single area domains too goes away. SPF is calculated in three phases. The first is the calculation of intra-area routes by building the shortest path tree for each attached area. The second phase calculates the inter-area routes by examining the summary LSAs and the last one examines the AS-External-LSAs to calculate the routes to the external destinations. QUESTION 387Which two orders in the BGP Best Path Selection process are correct? (Choose two.) A.    Higher local preference, then lowest MED, then eBGP over iBGP pathsB.    Higher local preference, then highest weight, then lowest router IDC.    Highest weight, then higher local preference, then shortest AS pathD.    Lowest origin type, then higher local preference, then lowest router IDE.    Highest weight, then higher local preference, then highest MED Answer: ACExplanation:Weight is the first attribute BGP uses in the route selection process. Route with a higher weight is preferred when multiple routes exist to the same destination. QUESTION 388Refer to the exhibit. Which action must you take to enable full reachability from router C to router D?   A.    Build an OSPF virtual link.B.    Build an OSPF sham link.C.    Configure mutual redistribution between OSPF and EIGRP on routers A and B.D.    Add a static route on router D. Answer: C QUESTION 389Which two Cisco Express Forwarding tables are located in the data plane? (Choose two.) A.    the forwarding information baseB.    the label forwarding information baseC.    the IP routing tableD.    the label information tableE.    the adjacency table Answer: AEExplanation: QUESTION 390Which option is the most effective action to avoid packet loss due to microbursts?

The numbers shown are STP link metrics.   After STP converges, you discover that traffic from switch SWG toward switch SWD takes a less optimal path.
