Question #11 (Topic: Single Topic)
SDWAN networks capitalize the usage of broadband Internet links over traditional MPLS links to offer more cost benefits to enterprise customers. However, due to
the insecure nature of the public Internet, it is mandatory to use encryption of traffic between any two SDWAN edge devices installed behind NAT gateways.
Which overlay method can provide optimal transport over unreliable underlay networks that are behind NAT gateways?

A. DTLS
B. TLS

D. GRE
Answer: C
Question #12 (Topic: Single Topic)
Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to monitor and keep track of any
performance issues by continuously collecting and analyzing statistical information to monitor, correct, and optimize any reduced responsiveness across the
network. Which layer accomplishes this design requirement?

B. performance management
C. accounting management
D. fault management
Answer: B
Question #13 (Topic: Single Topic)
Company XYZ has implemented policy-based routing in their network. Which potential problem must be kept in mind about network reconvergence and PBR?
A. It can limit network scalability.
B. It can create microloops during reconvergence.
C. It reduces convergence time.
D. It increases convergence time.
Answer: B
Question #14 (Topic: Single Topic)
SD-WAN can be used to provide secure connectivity to remote offices, branch offices, campus networks, data centers, and the cloud over any type of IP-based
underlay transport network. Which two statements describe SD-WAN solutions? (Choose two.)
underlay transport network. Which two statements describe SD-WAN solutions? (Choose two.)
A. Control and data forwarding planes are kept separate.
B. Solutions allow for variations of commodity and specialized switching hardware.
C. SD-WAN networks are inherently protected against slow performance.
D. Solutions include centralized orchestration, control, and zero-touch provisioning.
E. Improved operational efficiencies result in cost savings.
Answer: AD
Question #15 (Topic: Single Topic)
Company XYZ is in the process of identifying which transport mechanism(s) to use as their WAN technology. Their main two requirements are:
* a technology that could offer DPI, SLA, secure tunnels, privacy, QoS, scalability, reliability, and ease of management
* a technology that is cost-effective
Which WAN technology(ies) should be included in the design of company XYZ?
* a technology that could offer DPI, SLA, secure tunnels, privacy, QoS, scalability, reliability, and ease of management
* a technology that is cost-effective
Which WAN technology(ies) should be included in the design of company XYZ?
A. Both technologies should be used. Each should be used to back up the other one; where the primary links are MPLS, the Internet should be used as a backup link with IPsec (and vice versa).
B. MPLS meets all these requirements and it is more reliable than using the Internet. It is widely used with clearly defined best practices and an industry standard.
C. Software-defined WAN should be the preferred choice because it complements both technologies, covers all the required features, and it is the most cost- effective solution.
D. Internet should be the preferred option because it is cost effective and supports BFD, IP SLA, and IPsec for secure transport over the public Internet.
