BSCN questions --need help
Hi, Attached are some of the BSCN questions which are creating lot doubts in my mind. I found these questions on one of the web site while preparing for BSCN exam. Please help me in understanding them as web site's evaluation said that my answers were wrong. Please spare some time for these questions.. if possible today... Thanks a lot. Regards, Mahesh Here are the questions with my answers :- Question 9 of 40. Which OSPF mode of operation is not supported over NBMA topologies on a Cisco router? A. Broadcast B. Nonbroadcast point-to-point C. Nonbroadcast multi-access D. Point-to-point E. Point-to-multipoint My answer :- E as it is RPC mode and is not supported in some scenarios e.g. IP over ATM. Here I tried with option B as well but that was also wrong. Question 10 of 40. What generates an OSPF type-2 LSA? A. ABRs B. ASBRs C. DRs D. BDRs E. Each router for each area to which it belongs My answer :- C as Type 2 LSA's are Link LSA's. Question 13 of 40. Given the following configuration: outer ospf 20 network 10.3.3.2 0.0.0.0 area 0 network 10.4.4.1 0.0.0.0 area 3 network 10.5.0.0 0.0.255.255 area 3 area 0 range 10.3.0.0 255.255.0.0 area 3 range 10.4.4.0 255.255.255.0 area 3 range 10.5.0.0 255.255.0.0 Which statement about the difference between the effects of line 6 and the effects of line 7 is true? A. Line 6 advertises a single subnet into area 3 while line 7 advertises all subnets into area 3 B. Line 6 generates a host advertisement while line 7 generates a subnet advertisement C. Line 6 creates a more specific entry in the routing table of a router belonging to area 3 than does line 7 D. Line 6 advertises a single subnet into area 0 while line 7 advertises all subnets into area 0 My answer :-C seems to most logical... Question 27 of 40. Which of the following best completes the following statement? When configuring EIGRP for WAN interfaces, the BANDWIDTH statement is _. A. required for Frame Relay only B. required for subinterfaces only C. not required D. only used for multipoint circuits My answer :- no clue as very generic question guess was A or D but both were wrong. I thought A becasue specially in framerelay multipoint networks we put bandwidth but not necessarily only on subinterfaces. We may want to use the bandwidth command directly on a interface so that we can change the default value of T1 (1.544MB). Question 29 of 40. When using Enhanced IGRP in large scalable networks, why is additional EIGRP configuration required? A. To be hierarchical B. To adjust only WAN bandwidth because EIGRP is preconfigured (Plug and Play) C. To be monitored by the administrator D. To create manually entered summary routes My answer :- I tried A and D but both were wrong. any clue Question 37 of 40. Which is not a benefit of manual route summarization in EIGRP networks? A. Smaller routing tables B. Boundaries for query packets C. More rapid convergence D. A route to the null interface My answer :- C becasue if we limit query boundry, rapid concergence will automatically happen ?? Question 38 of 40. Which statement about an extended IP access list is true when configuring a distribute-list to filter BGP route advertisements on a Cisco router? A. It cannot be used; only standard IP access lists can be configured B. It can be used, to specify the source and destination IP address of the routes C. It can be used, to specify the network number and subnet mask of the routes D. It can be used, with a different syntax than the usual use of the extended IP access list My answer :- Tried B and D but was wrong ?? no idea .. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: BSCN questions --need help
Q.9 Ans should be C:Nonbroadcast multiaccess (NBMA) or E:Point-to-multipoint Ans C is fully meshed n/w and Ans E is for partially meshed n/w Q.10Ans C : DRs generated n/w link status and flood within the area. Q.13Ans C : Agree Q.27I think Ans C unless you want to change the physical BW Q.29I think Ans B Q.38. Ans D. The meaning of extended Access List Use in a Distribute List is different. The source parameters of the extended access list are used to indicate the address of the network whose updates are to be permitted or denied. The destination parameters of the extended access list are used to indicate the subnet mask of that network.

RE: BSCN questions --need help
Q.38 the answer should be: C. It can be used, to specify the network number and subnet mask of the routes. When using extended accesslist to do route filtering, the list will permit those route(s) which is/are *exactly match* the number of network prefix bit.
