If both ASBRs are advertising the external Destination X network as OSPF E2 route, what is the best path for the R1 router to reach Network X?
- A. R1 will use the path via ASBR 2 as the best path.
- B. R1 will use the pathvia ASBR 1 as the best path.
- C. R1 will load balance between two equal cost paths via ASBR 1 and ASBR 2.
- D. R1 will sees two equal costs and will choose the path through the ASBR with the lower OSPF router ID.
Answer : B
Explanation:
Refer to the show command output in the exhibit.
For which reason will this router drop all traffic that is destined to the 1.1.1.0/24 network?
- A. The 1.1.1.0/24 route is not synchronized.
- B. The BGP next hop for reaching the 1.1.1.0/24 network is not reachable.
- C. The metric of the 1.1.1.0/24 route is set to 0.
- D. The weight of the 1.1.1.0/24 route is set to 0.
- E. The 1.1.1.0/24 route is an incomplete route.
- F. The IBGP split-horizon rule is preventing the router to use the IBGP route.
Answer : B
Explanation:
Which of the following is used by an IS-IS router to detect other IS-IS neighbor routers and to form adjacencies?
- A. ESH
- B. ISH
- C. IIH
- D. PSNP
- E. CSNP
Answer : C
Explanation:
ISIS actually features three different hellotypes
An ES Hello (ESH) is send by all End Systems, and all IS devices listen for this Hello
An IS Hello (ISH) announces the presence of an IS - An IS Hello is sent by all IS devices, and End Systems listen for these hellos Finally, an IS-to-IS Hello (IIH)is used by an IS to discover other ISes and to form adjacencies with them A router will send an IIH to another router on the link to form or maintain an adjacency, but it will still send an ISH as well in case there are end systems located on that segment
How many total OSPF virtual links are configured in this multiarea OSPF network which supports both OSPFv2 and OSPFv3 for IPv4 and IPv6 routing?
- A. 1
- B. 2
- C. 3
- D. 4
Answer : B
Explanation:
#Show running-config | include virtual "" check how many router having "virtual " entry
Which statement is correct regarding the DR election process In this OSPF implementation?
- A. Both the CE5 and PE6 routers are DROTHERs
- B. PE5 is the OSPFv2 DR for the GigabitEthernet link between PE5 and PE6
- C. PE6 is the OSPFv2 and OSPFv3 DR for the GigabitEthernet link between PE5 and PE6
- D. PE6 is the DR for the GigabitEthernet link between PE5 and PE6 because it has a higher OSPF priority
Answer : A
Explanation:
