Refer to the exhibit.

Question # 21

This network is running IS-IS as the single routing protocol and the LSP and SPF timers are aggressively configured so the network converges in subsecond. The customer reports that router B had a memory crash and reloaded. Which resulted in some packets from the application being lost. The application servers are behind router G and the end users are behind router H, which design change should be made to prevent this packet-loss problem from reoccurring?

Options:

A.

Use asymmetric carrier delay timer


B.

Deploy all links as point-to-point


C.

Redesign the network as a flat level 2


D.

Optimize the LSP/SPF timers to send LSPs immediately after a topology change


E.

Enable the advertisement of the overload bit for a specific amount of time after reload on router B

Questions # 23:

A small local business recently had an outage after an employee plugged a switch into the corporate network, which caused the traffic pattern in the network to change. You have been tasked to redesign the network so that this does not happen again. From the left side to the right side, drag the PVRST+ features that should be implemented to prevent the corresponding root cause. Not all sources will be used.

Questions # 24:

Which two options are two advantages of summarizing networks at the aggregation layer rather than at the core? (Choose two.)

Options:

A.

It prevents the core from having unnecessary routes.


B.

It no longer needs a core layer.


C.

It prevents black hole routing.


D.

It avoids network-wide impact upon VLAN changes local to the aggregation devices.


E.

it allows for optimal routing

Questions # 25:

A switched network is being designed to support a manufacturing factory. Due to cost constraints, fiber-based connectivity is not an option. Which design allows for a stable network when there is a risk of interference from the manufacturing hardware in use on the factory floor?

Options:

A.

Design the network to include UDLD to detect unidirectional links and take them out of service.


B.

Design the network to include Ether Channel bundles to prevent a single-link failure from taking down a switch interconnection point.


C.

Design the network to include loop guard to prevent a loop in the switched network when a link has too much interference.


D.

Design the network to include Backbone Fast on all devices to accelerate failure convergence times.

Questions # 27:

A BGP route reflector in the network is talking longer than expected to converge during network changes. Troubleshooting has shown that the router cannot handle all the TCP acknowledgements during route updates. Which action can be performed to tune device performance?

Options:

A.

Increase the size of the large buffers


B.

Decrease the size of the small buffers


C.

Increase the keepalive timers for each BGP neighbor


D.

Increase the size of the hold queue

Options:

A.

Any source Multicast.


B.

PIM sparse mode.


C.

Bidirectional PIM.


D.

Source Specific Multicast.

Questions # 30:

You are solving a design failure on a massive Hadoop cluster network that has an application with TCP incast behavior (also known as TCP Throughput collapse) affecting its many-to-one communications with packet loss at the last-hop network device. Which metric must be measured to ensure that the network provides the best performance for this application?

Options:

A.

Availability


B.

Bandwidth utilization


C.

Jitter values


D.

Buffer utilization
