Question # 50

You are designing a new Ethernet-based metro-area network for an enterprise customer to connect 50 sites within the same city OSPF will be the routing protocol used. The customer is primarily concerned with IPv4 address conservation and convergence time. Which two combined actions do you recommend? (Choose two)

Use a multipoint Metro-E service for router connections

Use a single address per router for all P2P links

Use P2P links between routers in a hub-and-spoke design

Configure address aggregation at each site router

Determine which OSPF routers will be DR/BDR

Question # 51

The controller has a global view of the network, and it can easily ensure that the network is in a consistent and optimal configuration. Which two statements describe a centralized SDN control path? (Choose two.)

Scaling of the centralized controller cluster is challenging for services like DHCP and load-balancing.

It is highly-available by design with no single-point-of-failure risks present.

Integrating smart NIC capabilities on the local host level is made easier through rest APIs.

It significantly improves the latency when performing reactive handling of PACKET_IN events.

It centralized controller can support all southbound APIs, which allows for easy integration with legacy equipment.

Question # 52

Which two statements describe the functionality of OSPF packet-pacing timers? (Choose two )

The group-pacing timer controls the interval that is used for group and individual LSA refreshment

OSPF flood-pacing timers allow dynamic control of the OSPF transmission queue size

OSPF retransmission-pacing timers allow control of interpacket spaang between consecutive link-state update packets in the OSPF retransmission queue.

OSPF retransmission-pacing timers allow control of packet interleaving between nonconsecutive link-state update packets in the OSPF retransmission queue.

OSPF flood-pacing timers allow control of interpacket spacing between consecutive link-state update packets in the OSPF transmission queue

Implement filtering to control traffic that is sourced from the infrastructure IP space.

Enable and use only secure protocols.

Send logs to a centralized logging collection server.

Implement EBGP to advertise all owned IP blocks.

Use login banners and interface access lists to restrict administrative access to the system

Question # 55

Company XYZ plans to run OSPF on a DMVPN network. They want to use spoke-to-spoke tunnels in the design What is a drawback or concern in this type of design?

Additional host routes will be inserted into the routing tables

Manual configuration of the spokes with the appropriate priority will be needed

There will be split-horizon issue at the hub

Manual configuration of the spoke IP address on the hub will be needed

Question # 56

Refer to the table.

A customer investigates connectivity options for a DCI between two production data centers to aid a large-scale migration project. The migration is estimated to take 20 months to complete but might extend an additional 10 months if issues arise. All connectivity options meet the requirements to migrate workloads. Which transport technology provides the best ROI based on cost and flexibility?

CWDM over dark fiber

MPLS

DWDM over dark fiber

Metro Ethernet
