Which two features describe controller-based networking solutions compared to traditional networking solutions? (Choose two.)

• A. inflate licensing costs
• B. reduce network configuration complexity
• C. provide centralization of primary IT functions
• D. allow for fewer network failures
• E. increase network bandwidth usage

A software-defined networking (SDN) controller learns network topology information by using BGP link-state sessions with the route reflectors of an MPLS-enabled network. The controller then uses the topology information to apply on-demand traffic policies to the network through a protocol that is supported from all Layer 3 routers. Each policy is represented as a RIB entry in the control plane of the router. Which SDN model has been implemented?

• A. SDN centralized
• B. SDN traffic engineering
• C. SD-WAN
• D. SDN hybrid

Company XYZ is designing the IS-IS deployment strategy for their multiarea IS-IS domain. They want IS-IS neighbor relationships to be minimized on each network segment and want to optimize the size of the IS-IS LSDB on each router. Which can design can be used to meet these requirements?

• A. Design all routers as Level 2 routers. Set the links between the routers as Level 1 with the area
• B. Design the network so that the routers connecting to other areas are Level 2 routers and internal routers are Level 1
• C. Design the network so that all routers are Level 1 routers
• D. Design the network so that the routers connecting to other areas are Level 1/Level 2 routers and internal routers are Level 1

Which relationship between iBGP and the underlying physical topology is true?

• A. iBGP full mesh requires an underlying fully meshed network topology
• B. iBGP full mesh requirement does not dictate any specific network topology
• C. iBGP does not work on a ring network topology even with an underlying IGP
• D. iBGP can work only on a ring network topology with a link-state protocol like OSPF or IS-IS

Which two actions ensure voice quality in a branch location with a low-speed, high-latency WAN connection? (Choose two.)

• A. Prioritize voice packets
• B. Replace any electrical links with optical links
• C. Increase memory on the branch switch
• D. Fragment data packets
• E. Increase WAN bandwidth

Which two factors must be considered while calculating the RTO? (Choose two.)

• A. importance and priority of individual systems
• B. steps needed to mitigate or recover from a disaster
• C. cost of lost data and operations
• D. how often backups are taken and how quickly these can be restored
• E. maximum tolerable amount of data loss that the organization can sustain

An external edge router provides connectivity from a service provider to an enterprise. Which two Internet edge best practices meet compliance regulations? (Choose two.)

• A. Send logs to a centralized logging collection server
• B. Implement EBGP to advertise all owned IP blocks
• C. Enable and use only secure protocols
• D. Implement filtering to control traffic that is sourced from the infrastructure IP space
• E. Use login banners and interface access lists to restrict administrative access to the system

During evaluation of migrating current on-premises infrastructure to add cloud-based infrastructure, a network planning team must meet three core requirements as they make recommendations on which cloud strategy to adopt going forward. • Technology is changing rapidly, therefore the enterprise must be open to adopting new ways of doing things, and be ready to invest CapEx-funds in the next three years. • Network bandwidth capacity requirements are dynamic and are expected to change over the next year. • If new technologies are to be introduced operational expenses must be kept at a minimum. Which cloud strategy meets these requirements?

• A. private
• B. hybrid
• C. public
• D. multicloud
