Tolerance to packet loss

Intolerance to jitter

TCP based application

Question 12

Which three options are IS-IS design considerations when connecting two Layer 3 switches directly using a 10 GBASE-T cabling and formatting an IS-IS neighbor adjacency?

The default IS-IS network type is point-to-point so a DIS is not elected

A DIS is elected between the IS-IS neighbors and the elected DIS is pre-empted if router with a higher system ID is connected

The area, levels, and interface MTU parameters must match, and system MTU must be unique for two IS-IS routers to become adjacent

Faster IS-IS hello and dead timers increase bandwidth and CPU use, and may cause instability

The IS-IS hello and dead timers should be tuned to detect failures as quickly as possible

A DIS is elected between the IS-IS neighbors and the elected Dis is pre-empted if a router with a lower system ID is connected

The hello and dead timers must match for two IS-IS routers to become adjacent

Question 13

What is an implication of using route reflectors in an iBGP topology?

Route reflection limits the total number of iBGP routers.

Route reflection causes traffic to flow in a hub-and-spoke fashion.

The manipulation of BGP attributes is not supported on the other routers than the route reflectors.

Route reflectors can create routing loops when more than one router reflector is used in the same cluster.

Multipath information is difficult to propagate in a route reflector topology.

Question 14

Which open source message broker is in the Cisco Cloud Center?

Apache kafka

HornetQ

RabbitMQ

Fuse Message Broker

Oracle Message Broker

Question 15

Which two techniques are used in an OSPF network design to slow down the distribution of topology
information caused by a rapidly flapping link? (Choose two)

LSA throttling

SPF throttling

IP event dampening

Link-state incremental SPF

Link-state partial SPF

Question 16

A regional ISP is running MPLS TE. These tunnels are configured manually using paths. Which
technology centralizes the traffic engineering decisions to reduce operational complexity?

BGP Link State

DiffServ-TE

TE autobandwidth

Shared Risk link Group

Question 17

Which two options are IoT use cases that require the low-latency and high reliability that 5G
networks provide? (Choose two)

Sports and Fitness

Smart Home

Automotive

Smart Cities

Industrial Automation

Health and wellness

Question 18

Company ABC grew organically and now their single-area OSPF network has an unacceptably slow
convergence time after a topology change. To address the slow convergence time, they want to introduce a multiarea OSPF design and implement address summarization at the area border routers, which option should be their main concern about this redesign?

Routing is suboptimal

SPF calculation takes longer

Operations complexity is increased

More memory is needed across the routers on the network

Question 19

Refer to the exhibit.
352-001 dumps exhibit

Edge isolation

Question 21

A network has several routers running IS-IS L1L2 mode on the same Ethernet segment. Which action
reduces to a minimum the number of IS-IS adjacencies in this segment?

Define only the router on the segment to be DIS

Change all routers connected to this segment to a single-level area

Make the interface priority on the backup DIS lower than the primary DIS

Change half the routers to be L1-only and other half to be L2-only on this segment

(Choose two)

Ability to expand bandwidth over existing optical infrastructure

Question 23

You are designing a WAN network solution with EIGRP based on VPLS. The interface speed is 10Mb/s,
but the access rate of the WAN connection is 256 Kb/s. What should you include in the network design, in order to avoid potential issues with EIGRP?

Limit EIGRP traffic to the access rate with a policer.

Tag outbound EIGRP traffic and have the WAN provider add it to the priority queue.

Limit traffic to the access rate with interface traffic shaping.

Set the interface bandwidth to match the access rate.

Question 24

As network designer, which option is your main concern with regards to virtualizing multiple network
zones into a single hardware device?

Fate sharing

Question 25

As part of network design, two geographically separated data centers must be interconnected using
Ethernet-over-MPLS pseudowire. The link between the sites is stable, the topology has no apparent loops, and the root bridges for the respective VLANs are stable and unchanging. Which aspect must be the part of the design to mitigate the risk of connectivity issues between the data centers?

Enable 802.1d on one data center, and 802.1w on the other.

Ensure that the spanning tree diameter for one or more VLANs is not too large.

Enable UDLD on the link between the data centers.

Enable root guard on the link between the data centers.

Question 26

Which reason prevents a designer from using a GDOI-based VPN to secure traffic that traverses the
Internet?

Enterprise host IP addresses are typically not routable.

GDOI is less secure than traditional IPsec.

Network address translation functions interfere with tunnel header preservation.

The use of public addresses is not supported with GDOI.

Question 27

You are presented with requirements to design a development, testing and production environments. These environment should communicate with each other, yet they should be kept as separate failure domains. Which routing protocol should be configured on the links between the networks to support the design requirements?
