An engineer is upgrading a company’s main site to include a connection to a second ISP. The company will receive full Internet routing tables from both ISPs via BGP. The engineer must ensure that the company does not become a transit autonomous system. Which solution should be included in this design?
Tag incoming routes from both ISPs with BGP community no-export.
Lower the MED for updates sent to the secondary ISP.
Use a route-map to prevent all prefixes from being advertised to either ISP.
Modify the local-preference for routes incoming from the primary ISP.
Which two functions are provided by the Cisco SD-WAN orchestration plane? (Choose two.)
centralized provisioning
primary authentication point
NAT traversal facilitation
Zero Touch Provisioning
troubleshooting and monitoring
A large chain of stores currently uses MPLS-based T1 lines to connect their stores to their data center.
An architect must design a new solution to improve availability and reduce costs while keeping these considerations in mind:
» The company uses multicast to deliver training to the stores.
» The company uses dynamic routing protocols and has implemented QoS.
» To simplify deployments, tunnels should be created dynamically on the hub when additional stores open.
Which solution should be included in this design?
VPLS
GET VPN
DMVPN
IPsec
Which two techniques improve the application experience in a Cisco SD-WAN design? (Choose two.)
utilizing forward error correction
implementing a stateful application firewall
implementing AMP
utilizing quality of service
implementing Cisco Umbrella
How is redundancy achieved among Cisco vBond Orchestrators in a Cisco SD-WAN deployment?
The IP addresses of all Orchestrators are mapped to a single DNS name.
The closest Orchestrator to each Cisco WAN Edge router is selected.
Cisco WAN Edge routers are configured with all Orchestrators using their IP addresses and priority.
A single Cisco Orchestrator is deployed in each network.
Which PIM mode uses a shared tree only?
bidirectional
sparse
dense
source-specific
Which design element should an engineer consider when multicast is included in a Cisco SD-Access architecture?
PIM SSM must run in the underlay.
Multicast clients reside in the underlay, and the multicast source is outside the fabric or in the overlay.
Rendezvous points must be used in a PIM SSM deployment.
Multicast traffic is transported in the overlay and the EID space for wired and wireless clients.
What is the function of the multicast Reverse Path Forwarding check?
It allows for a loop-free distribution tree from the source to receivers.
It serves as an Auto RP Mapping agent.
It prevents bootstrap messages from reaching all routers.
It is used to discover and announce RP-set information.
A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?
Updates that contain changes within the data are sent only when changes occur.
Empty data subscriptions do not generate empty update notifications.
Periodic updates include a full copy of the data that is subscribed to.
The primary push update is sent immediately and cannot be delayed.
An architect is designing a multicast solution for a network that contains over 100 routers. The architect plans to create several multicast domains and balance the PIM-SM traffic within the network. Which technology should the architect include in the design?
DVMRP
IGMP
MOSPF
MSDP
