NEW QUESTION 5
Which service abstracts away the management of the operating system, middleware, and runtime?

• A. laaS
• B. PaaS
• C. SaaS
• D. BMaaS

Answer: B

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.

NEW QUESTION 7
A software-defined networking (SDN) controller teams network topology information by using BGP link-state sessions with the route reflectors of an MPLS-enabled network.

• A. SDN centralized
• B. SDN traffic engineering
• C. SD-WAN
• D. SDN hybrid

Answer: B

NEW QUESTION 8
When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two )

• A. Serialization delays are invariable because they depend only on the line rate of the interface
• B. Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.
• C. Serialization delay is the time required to transmit the packet on the physical media.
• D. Serialization delays are variable because they depend only on the size of the packet being serialized
• E. Serialization delay depends not only on the line rate of the interface but also on the size of the packet

Answer: BD
