What best describes the difference between Automation and Orchestration?

What are two key design principles when using a hierarchical core-distribution-access network model? (Choose two )

Company ABC wants to minimize the risk of users plugging unauthorized switches and hubs into the network. Which two features can be used on the LAN access ports to support this design requirement? (Choose two.)

Which purpose of a dynamically created tunnel interface on the design of IPv6 multicast services Is true?

An engineer is designing the network for a multihomed customer running in AS 111 does not have any other Ass connected to it. Which technology is more comprehensive to use in the design to make sure that the AS is not being used as a transit AS?

What is a disadvantage of the traditional three-tier architecture model when east west traffic between different pods must go through the distribution and core layers?

You want to mitigate failures that are caused by STP loops that occur before UDLD detects the failure or that are caused by a device that is no longer sending BPDUs. Which mechanism do you use along with UDLD?

Which two control plane policer designs must be considered to achieve high availability? (Choose two.)

The enterprise customer wants to stream one-way video from their head office to eight branch offices using multicast. Their current service provider provides a Layer3 VPN solution and manages the CE routers, but they do not currently support multicast. Which solution quickly allows this multicast traffic to go through while allowing for future scalability?

SDWAN networks capitalize the usage of broadband Internet links over traditional MPLS links to offer more cost benefits to enterprise customers. However, due to the insecure nature of the public Internet, it is mandatory to use encryption of traffic between any two SDWAN edge devices installed behind NAT gateways. Which overlay method can provide optimal transport over unreliable underlay networks that are behind NAT gateways?

What statement describes the application layer as defined in the software-defined networking architecture?

Company A has a hub-and spoke topology over an SP-managed infrastructure. To measure traffic performance metrics. IP SLA senders on all spoke CE routers and an IP SLA responder on the hub CE router. What must they monitor to have visibility on the potential performance impact due to the constantly increasing number of spoke sites?

Which two actions must be taken when assessing an existing wireless network implementation for its readiness to support voice traffic? (Choose two.)

An engineer is designing the QoS strategy for Company XYZ. Based on initial analysis, a lot of scavenger type of traffic is traversing the network's 20Mb Internet link toward the service provider. The new design must use a QoS technique that limits scavenger traffic to 2 Mbps, which helps avoid oversubscription of the link during times of congestion. Which QoS technique can be used to facilitate this requirement?

An enterprise has identified these causes for inefficient CAPEX spending: CAPEX planning is driven by technology and not by business objectives. The CAPEX planning team lacks the data it needs to perform due diligence tasks. The organizational structure lacks sufficient accountability and incentives. Which corporate cultural change contributes to improving the effectiveness of CAPEX spending?

Which SDN architecture component is used by the application layer to communicate with the control plane layer to provide instructions about the resources required by applications?

You were tasked to enhance the security of a network with these characteristics: ? A pool of servers is accessed by numerous data centers and remote sites ? The servers are accessed via a cluster of firewalls ? The firewalls are configured properly and are not dropping traffic ? The firewalls occasionally cause asymmetric routing of traffic within the server data center. Which technology should you recommend to enhance security by limiting traffic that could originate from a hacker compromising a workstatio
