Company XYZ, a global content provider, owns data centers on different continents. Their data center design involves a standard three-layer design with a Layer 3-only core. HSRP is used as the FHRP. They require VLAN extension across access switches in all data centers, and they plan to purchase a Layer 2 interconnection between two of their data centers in Europe. In the absence of other business or technical constraints, which termination point is optimal for the Layer 2 interconnection?

• at the core layer, to otter the possibility to isolate STP domains
• at me aggregation layer because it is the Layer 2 to Layer 3 demarcation point
• at the access layer because the STP root bridge does not need to align with the HSRP active node.
• at the core layer because all external connections must terminate there for security reasons

When consumers that leverage laaS reach 100% resource capacity, what can be used to redirect the overflow of traffic to the public cloud so there is no disruption to service?

• cloud policing
• cloud spill
• cloud bursting
• cloud shaping

A legacy enterprise is using a Service Provider MPLS network to connect its head office and branches. Recently, they added a new branch to their network. Due to physical security concerns, they want to extend their existing IP CCTV network of the head office to the new branch, without any routing changes in the network. They are also under some time constraints. What is the best approach to extend the existing IP CCTV network to the new branch, without incurring any IP address changes?

• GRE
• L2TPv3
• VXLAN
• EoMPLS

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

• inflate licensing costs
• reduce network configuration complexity
• provide centralization of primary IT functions
• allow for fewer network failures
• increase network bandwidth usage

While designing a switched topology, in which two options is UplinkFast recommended? (Choose two )

• when switches of different spanning-tree types are connected (for example. 802.1d connecting to 802.1w)
• on distribution layer switches
• when hello timers are changed to more aggressive values
• on access layer switches
• on the core switches

Company XYZ plans to run OSPF on a DMVPN network. They want to use spoke-to-spoke tunnels in the design What is a drawback or concern in this type of design?

• Additional host routes will be inserted into the routing tables
• Manual configuration of the spokes with the appropriate priority will be needed
• There will be split-horizon issue at the hub
• Manual configuration of the spoke IP address on the hub will be needed

A service provider recently migrated to an SD-WAN solution for delivering WAN connections to its customers. One of the main challenges with the SD-WAN deployment is that branch site volume increases every year, which causes management complexity. Which action resolves the issue?

• Implement a scalable network management system to manage all sites.
• Adopt a well-structured SD-WAN service management lifecycle model
• Build a service orchestration platform on top of the network controller
• Set up a dedicated team to monitor and provision new customers

Organizations that embrace Zero Trust initiatives ranging from business policies to technology infrastructure can reap business and security benefits. Which two domains should be covered under Zero Trust initiatives? (Choose two)

• workload
• work domain
• workplace
• workgroup
• workspace

Which security architecture component offers streamlined security operations, ease of use, and visibility across all network security elements, independent of location or form factor?

• threat-centric protection
• integrated actionable intelligence
• distributed enforcement
• central command and control
