How must queue sizes be designed to ensure that an application functions correctly?

A.

The default queue sizes are good for any deployment

B.

Each individual device queuing delay in chain must be less than or equal to the application required delay

C.

The queuing delay on every device in chain must be exactly the same

D.

The sum of the queuing delay of all devices in chain must be less than or equal to the application required delay

Refer to the exhibit.

An enterprise has three sites over a Layer 2 Metro Ethernet ELAN service. 100Mb/s and 10 Mb/s links have been provisioned to provide redundancy for the head office. When OSPF routing enabled to provide connectivity and the correct bandwidth statement has been applied to each interface, the branch sites observe two equal-cost routes to the head office. The enterprise wants to send all traffic through the 100 Mb/s link and use the 10Mb/S link strictly as a backup. Which OSPF network type must be set to ensure that the head office 100 Mb/s circuit is preferred over the 10 Mb/s circuit, at the same time minimize the amount of configuration required on all of the routers throughout the network?

A.

NBMA

B.

Point-to-multipoint

C.

Point-to-point

D.

Broadcast

Which three network management requirements are common practices in network design? (Choose three)

A.

Collect RMON poll information for future regression analysis

B.

Ensure that all network devices have their clocks synchronized

C.

Look at average counters instead of instantaneous counters for inconsistent and bursty KPIs, such as CPU utilization and interface utilization.

D.

Collect SNMP poll information for future regression analysis

E.

Validate data plane health, application and services availability with synthetic traffic

F.

Capture both ingress and egress flow-based packets. While avoiding duplications of flows

A new video multicast application is deployed in the network. The application team wants to use the 239.0.0.1 multicast group to stream the video to users. They want to know if this choice will impact the existing multicast design. What impact will their choice have on the existing multicast design?

A.

Because 239.0.0.1 is a private multicast range, a flood of PIM packets that have to be processed by the CPU and hosts will be sent by the routers in the network.

B.

Because 239.0.0.1 is a private multicast range, the rendezvous point has to send out constant group updates that will have to be processed by the CPU and hosts.

C.

The multicast application sends too many packets into the network and the network infrastructure drops packets.

D.

The 239.0.0.1 group address maps to a system MAC address, and all multicast traffic will have to be sent to the CPU and flooded out all ports.

Which mechanism provides fast path failure detection?

A.

Non-Stop Forwarding

B.

Carrier delay

C.

Graceful restart

D.

UDLD

E.

Fast hello packets

F.

For a redesign requirement of the service provider network, summarization was implemented at multiple locations for each summary range.

A.

Summarization adds CPU overhead on the routers sourcing the summarized advertisement.

B.

Summarization prevents the visibility of the metric to the component subnets.

C.

Summarization causes packet loss when RPF is enabled.

D.
