HPE6-A73 Exam - Question 44

Question

Examine the network topology.

The network is configured for OSPF with the following attributes:

✑ Core1 and Core2 and ABRs

✑ Area 1 has 20 networks in the 10.1.0.0/16 range

✑ Area 0 has 10 networks in the 10.0.0.0/16 range

✑ Area 2 has 50 networks in the 10.2.0.0/16 range

✑ The ASBR is importing a static route into Area 1

✑ Core2 has a summary for Area 2: area 0.0.0.2 range 10.2.0.0/16 type inter-area

Here is the OSPF configuration performed on Core1:

Based on the above information, what is correct?

Examice · Accepted Answer

Core1 has the 'passive-interface default' command configured, which means all interfaces are by default set to passive mode. Passive interfaces do not participate in OSPF adjacency formation and do not send or receive OSPF routing updates. Given there is no 'no passive-interface' command to override this passive behavior on VLAN 10 and VLAN 100 interfaces, Core1 will not be able to form any OSPF adjacencies and thus will have no OSPF routes.

NaCin · Answer

I think the correct answer is B. Because with "passive interface default" you would need a no passive interface on the Vlan 10 and Vlan 100 interfaces for neighborhoods to be established. C is not possible, because Area is stub not NSSA (Not-so-stuby-Area).

Davidkanigui · Answer

D is correct because area 1 is a Stub area, 2 routes for the inter-area networks + 1 default route from the ABR will be injected in Area in addition to the 20 route = 23

The correct Answer is B

DIOGENES · Answer

I read the aruba certified book, I found the answer for the question, Its D. two aggregate routes for inter-area (are0 10.0.0.0/16 and area1 10.1.0.0/16) and 1 default route for the ASBR.

B "passive interface defualt"

SeidorBruno · Answer

Page 332 Study Guide:
If you are only enabling OSPF on the VLAN because you want to advertise its subnet, and you do not want the router to form adjacencies with other routers on the VLAN, configure the VLAN as a passive OSPF interface.
[Aruba Networks]
As no "passive interface default" is Globally defined, no routes are advertised since on the VLANS there is no command "no passive-interface" configured.

seb6869 · Answer

The answer B is correct (miss no passive interface on SVI)

NetExpert · Answer

D is correct

[Removed] · Answer

B is correct.  If you do a 'passive interface default' under the global OSPF config, and then do NOT set the interface as 'no ip ospf passive', you get no neighbors, hence no OSPF routes.

The answer is A ?

acot333 · Answer

I think it's C

fasty · Answer

I also think it is C, core 1 should have 10 LSA 2, 2 LSA 3, 1 LSA 4 and 1 LSA 5, so A is not Correct

kadis500 · Answer

ths answer is not B , because when you perform: ip ospf x area x On interface , it will enable 
OSPF on this interface
