400-007 practice questions, page 12 of 14, with answer review and explanations.

Question 56

Which BGP feature provides fast convergence?

  1. BGP-LS
  2. BGP FlowSpec
  3. BGP-EVPN
  4. BGP PIC

Question 57

Refer to the exhibit. This network is running OSPF and EIGRP as the routing protocols. Mutual redistribution of the routing protocols has been configured on the appropriate ASBRs. The OSPF network must be designed so that flapping routes in EIGRP domains do not affect the SPF runs within OSPF. The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains. Which technique accomplishes the requirement?

  1. route summarization on the ASBR interfaces facing the OSPF domain
  2. route summarization on the appropriate ABRs
  3. route summarization on EIGRP routers connecting toward the ASBR
  4. route summarization on the appropriate ASBRs

Question 58

Which two mechanisms avoid suboptimal routing in a network with dynamic mutual redistribution between multiple OSPFv2 and EIGRP boundaries? (Choose two.)

  1. AD manipulation
  2. matching OSPF external routes
  3. route filtering
  4. matching EIGRP process ID
  5. route tagging

Question 59

Company XYZ has a new network based on IPv6. Some of the subnets that they are planning to use will be confidential and need an addressing scheme that confines them to the local campus network. Which type of IPv6 addresses can be used for these networks in the IPv6 addressing design?

  1. link-local addresses
  2. private addresses
  3. unique local addresses
  4. local addresses

Question 60

Refer to the exhibit. An engineer is designing a multiarea OSPF network for a client who also has a large EIGRP domain. EIGRP routes are getting redistributed into OSPF. OSPF area 20 has routers with limited memory and CPU resources. The engineer wants to block routes from EIGRP 111 from propagating into area 20 and allow EIGRP 222 routes to flow in. Which OSPF area type fulfills this design requirement?

  1. type 3 LSA filtering on the ABR between area 0 and area 20
  2. type 5 LSA filtering on the ASBR between EIGRP 111 and area 0
  3. area 20 as a stub area
  4. area 20 as a NSSA area
