Which two steps can be taken to improve convergence in an OSPF network? (Choose two.)
AUse Bidirectional Forwarding Detection

Refer to the exhibit. EIGRP has been configured on all links. The spoke nodes have been configured as EIGRP stubs, and the WAN links to R3 have higher bandwidth and lower delay than the WAN links to R4. When a link failure occurs at the R1-R2 link, what happens to traffic on R1 that is destined for a subnet attached to R2?
AR1 has no route to R2 and drops the traffic
BR1 load-balances across the paths through R3 and R4 to reach R2
CR1 forwards the traffic to R3, but R3 drops the traffic
DR1 forwards the traffic to R3 in order to reach R2
Which design consideration must be made when using IPv6 overlay tunnels?
AOverlay tunnels that connect isolated IPv6 networks are considered a final IPv6 network architecture.
BOverlay tunnels should only be considered as a transition technique toward a permanent solution.
COverlay tunnels should be configured only between border devices and require only the IPv6 protocol stack.
DOverlay tunneling encapsulates IPv4 packets in IPv6 packets for delivery across an IPv6 infrastructure.
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?
APIM-SM
BPIM-SSM
Cany-source multicast
DBIDIR-PIM
How do endpoints inside an SD-Access network reach resources outside the fabric?
Aa VRF fusion router is used to map resources in one VN to another VN
BFabric borders use VRFs to map VNs to VRFs
CSD-Access transit links are used to transport encapsulated traffic from one fabric to another
DA fabric edge is used to de-encapsulate VXLAN traffic to normal IP traffic then transported over the outside network
Which two border nodes are available in the Cisco SD-Access architecture? (Choose two.)
Aextended border
Bedge border
Cinternal border
Danywhere border
Eintermediate border
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?
ATag incoming routes from both ISPs with BGP community no-export.
BLower the MED for updates sent to the secondary ISP.
CUse a route-map to prevent all prefixes from being advertised to either ISP.
DModify the local-preference for routes incoming from the primary ISP.
Which control-plane technology allows the same subnet to exist across multiple network locations?

In an SD-WAN architecture, which methods are used to bootstrap a vEdge router?

A company is using OSPF between its HQ location and a branch office. HQ is assigned area 0 and the branch office is assigned area 1. The company purchases a second branch office, but due to circuit delays to HQ, it decides to connect the new branch office to the existing branch office as a temporary measure. The new branch office is assigned to area 2. Which OSPF configuration enables all three locations to exchange routes?
AThe existing branch office must be configured as a stub area
BA virtual link must be configured between the new branch office and HQ
CA sham link must be configured between the new branch office and HQ
