問題#1

A cloud design contains multiple hosts that are running a hypervisor. Each host has only two physical 10 Gb network adapters that are aggregated for bandwidth and failover. The physical switch ports for each host are configured as access ports. Each host will support numerous virtual machines and network segments. These virtual machines will communicate with other virtual machines on the same network segments.
Why would overlay networks be required for this design?

A. Support for more than two virtual switches

B. Support for more than one virtual segment

C. Support for more than two virtual machines

D. Support for more than one distributed virtual switch

Explanation:
An overlay network is a computer network that is built on top of another network. Nodes in the overlay network can be thought of as being connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network.
Virtual overlay networks use tunneling protocols to extend isolated network segments between servers for multi-tenant data center networks.

問題#2

An organization is developing a cloud-native social-media website. The website will be written using elastic principles. When the website scales, it can add additional web, application and database instances to meet dynamic workload demand.
Which additional resources will be consumed by replication as the database layer expands.

A. Public IP addresses, CPU, and memory

B. CPU, memory, and network traffic

C. Network traffic, public IP addresses, and CPU

D. Memory, network traffic, and public IP addresses

問題#3

A company wants to build an IaaS cloud to host cloud-native applications.
On which areas should a cloud architect focus when gathering requirements for this cloud design?

A. Automation, multi-tenancy, and hardware availability

B. Automation, hardware availability, and policy compliance

C. Hardware availability, policy compliance, and multi-tenancy

D. Policy compliance, automation, and multi-tenancy

Explanation:
*Multi-tenancy
Infrastructure as a Service is very similar to what we've known as hosting or collocation services, just painted with bright cloudy colors. Multi-tenant services are any services that you offer to multiple customers, or "tenants." In most cases, IaaS and multi-tenant services mean the same thing, although you could also implement storage- or database-related multi-tenant service.
*Hardware
In the case of IaaS the computing resource provided is specifically that of virtualised hardware, in other words, computing infrastructure. Note: Infrastructure as a Service (IaaS) is a form of cloud computing that provides virtualized computing resources over the Internet.

問題#4

Which additional considerations must a cloud monitoring system address compared to a traditional monitoring system?

A. Tenant isolation, orchestration, and elastic workloads

B. Orchestration, elastic workloads, and Data at Rest security

C. Elastic workloads, Data at Rest security, and tenant isolation

D. Data at Rest security, tenant isolation, and orchestration

Explanation:
* Encrypt data-at-rest
Encryption is your front-line defense for defending data-at-rest. It limits access to those with the right keys C locking out anyone who doesn’t have them.

問題#5

An organization wants to provide backup services in the cloud. They have no backup infrastructure in place. The organization has concerns about losing data if a site disaster occurs. They want to maintain control of backup data placement because of data privacy laws. Finally, they want to maintain at least one month’s worth of backups onsite.
Which backup solution will meet these requirements?

A. Local backup

B. Remote backups

C. Local backup with replication

D. Local backups with cloud gateway

Explanation:
Cloud gateway allows EMC customers to move on-premise data from EMC arrays to public cloud storage providers. Clod gateway facilitate data migration from on-premises to a public cloud storage service to create a true hybrid cloud storage environment. Cloud gateways such as Riverbed’s SteelStore (formally known as Whitewater) can act as a local backup target for funneling data to a storage cloud for offsite storage.
