In the case of outsourced IT services, the RTO is defined within the SLA. Which two support terms are often included in the SLA by IT and other service providers? (Choose two.)
Answer(s): A,E
-Resolution time refers to the amount of time it takes for a service provider to resolve an issue. This is usually measured in hours or days.-Support availability refers to the hours and days that support is available. This is usually specified as 24/7 or M-F, 8am-5pm.The other options are also important, but they are not as commonly included in SLAs.-Network reliability is the likelihood that a network will be available and functioning properly. This is usually measured as a percentage.-Network size and cost are important factors to consider when selecting a service provider, but they are not typically included in SLAs.-Network sustainability refers to the ability of a network to withstand changes and disruptions. This is not typically included in SLAs, but it is an important consideration for organizations that rely on their networks for critical business functions.-
Which two statements explain the operation of BFD asynchronous mode? (Choose two.)
Answer(s): A,B
Various teams in different organizations within an enterprise are preparing low-level design documents to capture network parameters using a Waterfall project model:•hardware sizing and power consumption•Layer 2 and layer 3 services parameters•configuration of all control plane protocolsInput from relevant stakeholders was captured at the start of the project, and the project scope has been defined based on the parameters above. What impact will it have on documentation and project deliverables if the stakeholders ask to have changes earned out in the network before the information has been captured?
Answer(s): B
Which two benefits can software defined networks provide to businesses? (Choose two.)
Answer(s): C,E
-C. Reduced latency: SDN can reduce latency by centralizing the control of the network and by making it easier to optimize traffic flows.-E. Reduction of OpEx/CapEx: SDN can reduce OpEx/CapEx by making it easier to manage and maintain the network, and by enabling the use of less expensive hardware.The other options are also benefits of SDN, but they are not as significant as the two listed above.-Provides additional redundancy: SDN can provide additional redundancy by allowing the network to be divided into multiple zones, each of which can be managed independently.-Decentralized management: SDN can allow for decentralized management by making it possible to delegate control of the network to different teams or departments.-Enables innovation: SDN can enable innovation by making it easier to deploy new network services and applications.-F. Meets high traffic demands: SDN can meet high traffic demands by making it easier to scale the network and by providing more granular control over traffic flows.
Company XYZ is migrating their existing network to IPv6 and they must plan for Layer 2 and Layer 3 devices. Some of the access layer switches do not support IPv6, however, core and distribution switches fully support unicast and multicast routing. The company wants to minimize cost of the migration. Which migration strategy should be used in the design?
Answer(s): C
As layer 2 switches can potentially impact the implementation of IPv6, particularly if they do not support features such as Neighbor Discovery Protocol (NDP) and Stateless Address Autoconfiguration (SLAAC).
