Question # 9

A company wants to enable several third-party video conferencing networks based on multicast services. The video conferencing platform can accommodate numerous and dispersed senders and receivers in third-party networks The interior routing protocol is OSPF and the exterior routing protocol is BGP Which multicast mode must be selected to achieve this goal?

Enable MP-BGP

Enable BIDIR-PIM

Configure MSDP

Set IGMPv2.

Question # 10

Which design consideration should be observed when EIGRP is configured on Data Center switches?

Perform manual summarization on all Layer 3 interfaces to minimize the size of the routing table.

Prevent unnecessary EIGRP neighborships from forming across switch virtual interfaces.

Lower EIGRP hello and hold timers to their minimum settings to ensure rapid route reconvergence.

Configure multiple EIGRP autonomous systems to segment Data Center services and applications.

Question # 11

Which design consideration must be made when using IPv6 overlay tunnels?

Overlay tunnels that connect isolated IPv6 networks can be considered a final IPv6 network architecture.

Overlay tunnels should only be considered as a transition technique toward a permanent solution.

Overlay tunnels can be configured only between border devices and require only the IPv6 protocol stack.

Overlay tunneling encapsulates IPv4 packets in IPv6 packets for delivery across an IPv6 infrastructure.

Question # 14

An engineer must connect a new remote site to an existing OSPF network. The new site consists of two low-end routers, one for WAN, and one for LAN. There is no demand for traffic to pass through this area. Which area type does the engineer choose to provide minimal router resources utilization, while still allowing for full connectivity to the rest of the network?

not so stubby

totally not so stubby

totally stubby area

stubby area

OpenConfig models are more comprehensive than IETF.

Cisco native models are less comprehensive than OpenConfig.

Cisco native models are less comprehensive than IETF.

IETF models are more comprehensive than OpenConfig.

Question # 16

Refer to the exhibit. Area 10 is a regular OSPF area and networks 10.1.1.0/24 and 172.16.1.0/24 are internal. Which design provides optimal routing between both networks when the link between routers C and E fails?

Move the link between routers C and D to area 10.

Create an OSPF virtual link between routers E and F.

Create a tunnel between routers E and F in area 10.

Make area 10 a not-so-stubby area.
