Question #11
An organization plans to deploy many cloud-native applications that will generate a considerable amount of east-west traffic. The cloud-native applications will be deployed on hosts running hyppervisors.
Why would distributed routers be considered in this design?
Why would distributed routers be considered in this design?
- AEnable network segment
- BImprove network performance between hosts
- CMinimize Internet traffic
- DProtect against a physical router failure
Correct Answer:
B
Distributed Virtual Router (DVR) aims to isolate the failure domain of the traditional network node and to optimize network traffic by eliminating the centralized L3 agent. It does that by moving most of the routing previously performed on the network node to the compute nodes.
* East/west traffic (Traffic between different networks in the same tenant, for example between different tiers of your app) previously all went through one of your network nodes whereas with DVR it will bypass the network node, going directly between the compute nodes hosting the VMs.
Etc.

Question #12
An architect is designing the compute resource pools for a cloud. As part of the deliverables, the architect has included the standard specifications for the physical servers to be used. The organization has provided estimates for future growth but has concerns about whether these estimates are accurate.
What should be included in the design to address these concerns?
What should be included in the design to address these concerns?
- AA monitoring application and procedures for pool expansion
- BA chargeback application and orchestration workflows to auto-scale pools
- CA metering application and orchestration workflows to auto-scale pools
- DA configuration management application and procedures for pool expansion

Question #13
An organization wants to deploy a service catalog in a private cloud. What requirements are met by using a service catalog?
- AAbility for administrators to manage multi-tenancy
- BAbility for users to measure service performance
- CAbility for users to aggregate service logs
- DAbility for administrators to attach storage pools
Correct Answer:
B
Benefits of implementing and maintaining a service catalog include allowing an enterprise to track and manage metrics that represent the utilization of services and service-related traits, such as those associated with service supply and demand.

Question #14
After developing prototype applications in the public cloud, developers determined that they want software-defined network functionality. Which ability will this requirement provide for the developers?
- AProgrammatically provision an IPsec VPN tunnel between the public and private clouds
- BProgrammatically migrate layer-3 access from aggregate to access switches
- CProgrammatically control physical core network topologies
- DProgrammatically provision physical network segments and services
Correct Answer:
D
Software-defined networking (SDN) is an approach to computer networking that allows network administrators to manage network services through abstraction of higher-level functionality. This is done by decoupling the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forward traffic to the selected destination (the data plane).

Question #15
What needs to be considered when designing a distributed storage solution?
- AMultiple management tools
- BFault domain detection and isolation to ensure data availability
- CRAID configuration to ensure a drive failure is avoided
- DAutomated storage tiering to enable efficient use of drive
Correct Answer:
B
A distributed data store is a computer network where information is stored on more than one node, often in a replicated fashion. Distributed data stores typically use an error detection and correction technique. Some distributed data stores (such as Parchive over NNTP) use forward error correction techniques to recover the original file when parts of that file are damaged or unavailable. Others try again to download that file from a different mirror.
