Question 1 2 / 2 pts (TCO 4) Why would you use multi-area OSPF?   You have been assigned an autonomous system number.   You have expanded your operations outside of your home country. Correct!   SPF computations are growing.   SPF computations are decreasing. See Chapter 6.   Question 2 2 / 2 pts (TCO 4) In multi-area OSPF all areas must connect to the _____.   MBone area Correct!   backbone area   headquarters area   designated router See Chapter 6.   Question 3 2 / 2 pts (TCO 4) Router summarization keeps _____.   routing tables robust Correct!   routing tables small   neighbor tables updated   LSA for failing See Chapter 6.   Question 4 2 / 2 pts (TCO 4) With multi-area OSPF, which OSPF router type has all interfaces in the same area?   AS router   Gateway router   External router Correct!   Internal router See Chapter 6.   Question 5 2 / 2 pts (TCO 4) Which type of routing table entry would indicate that an external route was redistributed into the multi-area OSPF process?   S Correct!   O   E1   R   O See Chapter 6.   Question 6 2 / 2 pts (TCO 4) Why would you use multi-area OSPF?   You have been assigned an autonomous system number.   You have expanded your operations outside of your home country.   SPF computations are decreasing. Correct!   SPF computations are growing. See Chapter 6.   Question 7 2 / 2 pts (TCO 4) End users are typically not found in what area?   End users are in all areas   The regular area Correct!   The backbone area   The transitory area See Chapter 6.   Question 8 2 / 2 pts (TCO 4) There are four types of OSPF routers. Which type connects to multiple areas?   MBone router   Backbone router Correct!   Area border router   BGP router See Chapter 6.   Question 9 Not yet graded / 4 pts (TCO 4) List and explain three reasons for using multi-area OSPF. Chapter 6 Smaller routing tables: There are fewer routing table entries as network addresses can be summarized between areas. Reduced link-state update overhead: Minimizes processing and memory requirements, because there are fewer routers exchanging LSAs. Reduced frequency of SPF calculations: Localizes impact of a topology change within an area. For example, it minimizes routing update impacts, because LSA flooding stops at the area boundary.
