Which two functions are performed by the core layer in a three-tier architecture? (Choose two) Inspect packets for malicious activity Provide uninterrupted forwarding service Ensure timely data transfer between layers Provide direct connectivity for ende user devices Police traffic that is sent to the edge of the network.
A company needs to interconnect several branch offices across a metropolitan area. The network engineer is seeking a solution that provides high-speed converged traffic, including voice, video, and data on the same network infrastructure. The company also wants easy integration to their existing LAN infrastructure in their office locations. Which technology should be recommended? ISDN Ethernet WAN VSAT Frame Relay.
Which two WAN architecture options help a business improve scalability and reliability for the network? (Choose two) dynamic routing static routing asychronous routing single-homed branches dual-homed branches.
Which purpose does a northbound API serve in a controller-based networking architecture? facilitates communication between the controller and the applications reports device errors to a controller communicates between the controller and the physical network hardware generates statistics for network hardware and traffic.
Which function is performed by the collapsed core layer in a two-tier architecture? enforcing routing policies marking interesting traffic for fata policies attaching users to the edge pf the network applying security policies.
Which function is performed by the collapsed core layer in a two-tier architecture? broadband cable access dedicated point-to-point leased line frame-relay packet switching Integrated Services Digital Network Switching.
What benefit does controller-based networking provide versus traditional networking? allows configuration and monitoring of the network from one centralized port moves from a two-tier to a three-tier network architecture to provide maximum redundancy combines control and data plane functionality on a single device to minimize latency provides an added layer of security to protect from DDoS attacks.
What is the name of the layer in the Cisco borderless switched network design that is considered to be the backbone used for high-speed connectivity and fault isolation? network network acces access core data link.
What is a characteristic of spine-and-leaf architecture? Each device is separated by the same number the hops It provides variable latency It provides greater predictability on STP blocked ports Each link between leaf switches allows for higher bandwidth.
What are two descriptions of three-tier network topologies? (Choose two) The core and distribution layers perform the same functions The network core is designed to maintain continuous connectivity when devices fail The core layer maintains wired connections for each host The distribution layer runs Layer 2 and Layer 3 technologies The access layer manages routing between devices in different domains.
