This network is running OSPF and EIGRP as the routing protocols Mutual redistribution of the routing protocols has been contoured on the appropriate ASBRs The OSPF network must be designed so that flapping routes m 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?
- A. route summarization on the appropriate ASBRS.
- B. route summarization on EIDRP routers connecting toward the ASBR
- C. route summarization the ASBR interfaces facing the OSPF domain

NEW QUESTION # 59
Which service abstracts away the management of the operating system, middleware, and runtime?
- A. laaS
- B. BMaaS
- C. SaaS
- D. PaaS
Answer: D
Explanation:
IaaS, PaaS, and SaaS each offer a progressive layer of abstraction after that. IaaS abstracts away the physical compute, network, storage, and the technology needed to virtualize those resources. PaaS goes a step further and abstracts away the management of the operating system, middleware, and runtime.
