Which OSPF area blocks LSA Type 3, 4 and 5, but allows a default summary route?
D. totally stubby
An engineer is working for a large cable TV provider that requires multiple sources streaming video on different channels using multicast with no rendezvous point. Which multicast protocol meets these requirements?
C. any-source multicast
Which two techniques improve the application experience in a Cisco SD-WAN design? (Choose two.)
A. utilizing forward error correction
B. implementing a stateful application firewall
C. implementing AMP
D. utilizing quality of service
E. implementing Cisco Umbrella
The customer solution requires QoS to support streaming multimedia over a WAN. An architect chooses to use Per-Hop Behavior. Which solution should the engineer use to of mark traffic traveling between branch sites?
A. LLQ with DSCP EF
B. CBWFQ with DSCP AF3
C. CBWFQ with DSCP AF2
D. LLQ with DSCP AF4
What is the purpose of a control plane node in a Cisco SD-Access network fabric?
A. to maintain the endpoint database and mapping between endpoints and edge nodes
B. to detect endpoints in the fabric and inform the host tracking database of EID-to-fabricedge node bindings
C. to identify and authenticate endpoints within the network fabric
D. to act as the network gateway between the network fabric and outside networks
Which two statements describe source trees in a multicast environment? (Choose two.)
A. Source trees guarantee the minimum amount of network latency for forwarding multicast traffic
B. Source trees create an optimal path between the source and the receivers
C. Source trees use a single common root placed at some chosen point in the network
D. Source trees can introduce latency in packet delivery
E. Source trees can create suboptimal paths between the source and the receivers
A customer with an IPv4 only network topology wants to enable IPv6 connectivity while preserving the IPv4 topology services. The customer plans to migrate IPv4 services to the IPv6 topology, then decommission the IPv4 topology. Which topology supports these requirements?
A. dual stack
A customer's current Layer 2 infrastructure is running Spanning Tree 802.1d, and all configuration changes are manually implemented on each switch. An architect must redesign the Layer 2 domain to achieve these goals:reduce the impact of topology changesreduce the time spent on network administrationreduce manual configuration errorsWhich two solutions should the architect include in the new design? (Choose two.)
A. Implement Rapid PVST+ instead of STP.
B. Implement MST instead of STP.
C. Use VTP to propagate VLAN information and to prune unused VLANs.
D. Configure broadcast and multicast storm control on all switches.
E. Configure dynamic trunking protocol to propagate VLAN information.
Which design consideration must be made when using IPv6 overlay tunnels?
A. Overlay tunnels that connect isolated IPv6 networks can be considered a final IPv6 network architecture.
B. Overlay tunnels should only be considered as a transition technique toward a permanent solution.
C. Overlay tunnels can be configured only between border devices and require only the IPv6 protocol stack.
D. Overlay tunneling encapsulates IPv4 packets in IPv6 packets for delivery across an IPv6 infrastructure.
What is the function of the multicast Reverse Path Forwarding check?
A. It allows for a loop-free distribution tree from the source to receivers.
B. It serves as an Auto RP Mapping agent.
C. It prevents bootstrap messages from reaching all routers.
D. It is used to discover and announce RP-set information.
An engineer is designing a multicast network for a financial application Most of the multicast sources also receive multicast traffic (many-to-many deployment model). To better routing tables, the design must not use source trees. Which multicast protocol satisfies these requirements?
