Question # 54

The major business applications of an enterprise are largely monolithic and hard-coded. As part of a major modernization and overhaul of the applications, the goal is to move to a modular and containerized application architecture model. At the same time, decoupling from the hardware is desired to move to an on-demand provisioning. However, the CyberOps team mandated that the final architecture must provide the same security levels as an air-gapped data center. Which cloud architecture meets these requirements?

Options:

A.

IaaS

B.

Private cloud

C.

PaaS

D.

Hybrid cloud

E.

Public cloud

Options:

A.

Change the OSPF reference bandwidth to accommodate faster links.

B.

Filter the routes on the link between London and Rome.

C.

Change the interface bandwidth on all the links.

Question # 56

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?

Options:

A.

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.

B.

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.

C.

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).

D.

MPLS meets all these requirements and it is more reliable than using the Internet. It is widely used with defined best practices and an industry standard.
