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.10 Ans C : DRs generated n/w link status and flood within the area.
Q.13 Ans C : Agree
Q.27 I think Ans C unless you want to change the physical BW
Q.29 I 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.

> Question 9 of 40.
> Which OSPF mode of operation is <u>not</u> 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

>
> 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 <u>not</u> 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 ..
