1. An architect designs a multi-controller network architecture with these requirements:

✑ Achieve fast failover to control traffic when controllers fail.

✑ Yield a short distance and high resiliency in the connection between the switches and the controller.

✑ Reduce connectivity loss and enable smart recovery to improve the SDN survivability.

✑ Improve connectivity by adding path diversity and capacity awareness for controllers.

control node reliability

controller stale consistency

controller clustering

2. What advantage of placing the IS-IS layer 2 flooding domain boundary at the core Layer in a three-layer hierarchical network is true?

The Layer 1 and Layer 2 domains can easily overlap

It reduces the complexity of the Layer 1 domains

It can be applied to any kind of topology

The Layer 2 domain is contained and more stable

when switches of different spanning-tree types are connected (for example. 802.1d connecting to 802.1w)

on distribution layer switches

when hello timers are changed to more aggressive values

on access layer switches

on the core switches

4. You have been asked to design a high-density wireless network for a university campus.

Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

Implement a four-channel design on 2.4 GHz to increase the number of available channels

Choose a high minimum data rate to reduce the duty cycle.

increases the number of SSlDs to load-balance the client traffic.

Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.

Enable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.

5. Which two types of planning approaches are used to develop business-driven network designs and to facilitate the design decisions? (Choose two)

cost optimization approach

strategic planning approach

modular approach

tactical planning approach

business optimization approach

6. Company XYZ is redesigning their QoS policy. Some of the applications used by the company are real-time applications. The QoS design must give these applications preference in terms of transmission.

Which QoS strategy can be used to fulfill the requirement?

weighted fair queuing

weighted random early detection

low-latency queuing

first-in first-out

7. A network design includes a long signaling delay in notifying the Layer 3 control plane that an interface has failed.

Which two of these actions would reduce that delay? (Choose two.)

Increase network stability.

Reduce the time for the network to reconverge.

Increase the notification of interface flaps.

Enable lower data link layer recovery systems to have an opportunity to restore the interface

8. SDWAN networks capitalize the usage of broadband Internet links over traditional MPLS links to offer more cost benefits to enterprise customers. However, due to the insecure nature of the public Internet, it is mandatory to use encryption of traffic between any two SDWAN edge devices installed behind NAT gateways.

Which overlay method can provide optimal transport over unreliable underlay networks that are behind NAT gateways?

TLS

DTLS

IPsec

GRE

9. Refer to the exhibit.

There are multiple trees in the Cisco FabricPath All switches in the Layer 2 fabric share the same view of each tree.

Which two concepts describe how the multicast traffic is load-balanced across this topology? (Choose two)

A specific (

G) traffic is not load-balanced

All trees are utilized at the same level of the traffic rate

Every leaf node assigns the specific (

G) to the same tree.

A specific (

G) multicast traffic is load-balanced across all trees due to better link utilization efficiency.

The multicast traffic is generally load-balanced across all trees

10. Refer to the exhibit.

Your company designed a network to allow server VLANs to span all access switches in a data center. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches.

Which two features improve STP stability within the network design? (Choose two.)

BPDU guard on access ports

BPDU guard on the aggregation switch downlinks toward access switches

root guard on the aggregation switch downlinks toward access switches

root guard on access ports

edge port on access ports

access switch pairs explicitly determined to be root and backup root bridges

11. Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to monitor and keep track of any performance issues by continuously collecting and analyzing statistical information to monitor, correct, and optimize any reduced responsiveness across the network.

Which layer accomplishes this design requirement?

fault management

accounting management

performance management

security management

12. Which technology is an open-source infrastructure automation tool that automates repetitive tasks for users who work in networks such as cloud provisioning and intraservice orchestration?

Ansible

Contrail

Java

Jinja2

13. Which two mechanisms avoid suboptimal routing in a network with dynamic mutual redistribution between multiple OSPFv2 and EIGRP boundaries? (Choose two.)

AD manipulation

matching OSPF external routes

route tagging

route filtering

matching EIGRP process ID

14. Your company wants to deploy a new data center infrastructure Based on the requirements you have chosen VXLAN as encapsulation technology. The customer is concerned about miss-configuration of Layer 2 devices and DC wide outages caused by Layer 2 loops.

What do you answer?

VXLAN offers native loop avoidance mechanism

Storm Control should be enabled on all ports

VPC+ could prevent L2 loop on access ports

BPDU Guard should be enabled on all VTEP access ports

15. Refer to the exhibit.

As part of a redesign project, you must predict multicast behavior.

What happens to the multicast traffic received on the shared tree (*,G), if it is received on the LHR interface indicated*?

It is dropped due to an unsuccessful RPF check against the multicast source

It is switched give that no RPF check is performed

It is switched due to a successful RPF check against the routing table

It is dropped due to an unsuccessful RPk8t8ck against the multicast receiver.

16. Which design consideration is valid when you contrast fabricPath and trill?

FabricPath uses IS-IS, but TRILL uses VxLAN

FabricPath permits active-active FHRP and TRILL support anycast gateway.

FabricPath Permits ECMP, but TRILL does not

FabricPath permits active-active mode, but TRILL supports only active-standby mode.

17. You are designing a network running both IPv4 and IPv6 to deploy QoS.

Which consideration is correct about the QoS for IPv4 and IPv6?

IPv4 and IPv6 traffic types can use use queuing mechanisms such as LLQ, PQ and C

IPv6 packet classification is only available with process switching, whereas IPv4 packet classification is available with both process switching and CE

IPv6 and IB/4 traffic types can use a single QoS policy to match both protocols

Different congestion management mechanisms need to be used for IPv4 and IPv6 traffic types
