Question 1

You are asked to configure your IP fabric with OSPF as the underlay routing protocol.

Which two statements are correct about this implementation? (Choose two.)

AEach host-connected interface of the leaf node is included as passive in the OSPF configuration.

BEach host-connected interface of the leaf node is included in the OSPF configuration.

CEach spine-connected interface of the leaf node is included as passive in the OSPF configuration.

DEach spine-connected interface of the leaf node is included in the OSPF configuration.

Answer : A, D

Question 2

You want to monitor the value of a MIB object or variable against configured thresholds and generate a corresponding event when the value of a variable crosses a threshold.

In this scenario, which feature should you use to accomplish this task?

Agenerate-event

BEvent Script

CRMON

DEvent Policy

Answer : C

Question 3

You have successfully deployed an IP fabric in your data center. However, your server team complains that they are not seeing an increase in performance as expected. After examining the routing and forwarding tables, you notice that only a single route is listed to each destination in the forwarding table, even though there are multiple routes shown in the routing table.

In this scenario, what should you do to solve the problem?

AWrite a load balancing policy and apply it to the routing table.

BModify the hash algorithm so that only source and destination addresses are used.

CWrite a load balancing policy and apply it to the forwarding table.

DDisable the Spanning Tree Protocol that is blocking the redundant paths.

Answer : C

Question 4

Which two statements about an over-the-top (OTT) data center interconnect architecture are correct? (Choose two.)

AFor a Layer 2 stretched network between data centers, a full mesh of VXLAN tunnels between leaf switches is required.

BIBGP or EBGP is required for the underlay.

CMulticast is supported.

DOTT is ideal for small and medium data center designs.

Answer : A, B

Question 5

You have a data center design with multiple tenants using routing instances.

In this scenario, what are two ways to provide inter-tenant communications? (Choose two.)

AUse EVPN type-7/8 routes.

BUse RIB groups.

CUse filter-based forwarding.

DUse EVPN type-6 routes.

Answer : A, D

Question 6

You are designing a Layer 3 fabric underlay using EBGP. You will implement an E VPN-signaled

VXLAN overlay on the Layer 3 fabric.

In this scenario, what must you do in the underlay to ensure that the VXLAN overlay will be able to function properly?

AThe underlay should support the PIM protocol

BEach device in the underlay should advertise its loopback address

CThe underlay should be configured with a separate VRF tor each potential tenant

DThe underlay should advertise the host connected interlaces on all leaf device

Answer : B

For a VXLAN overlay to function properly over a Layer 3 EBGP fabric underlay, it's essential that each device in the underlay advertises its loopback address. This ensures reachability between the devices, facilitating proper tunnel establishment for the VXLAN overlay.

Question 7

What is the purpose of the command shown in the exhibit?

ATo stop the reception of transit multicast traffic when there are no interested receives attached to the local VTEP

BTo disable the group2390.0.1 across the entire VXLAN.

CTo stop the transmission of transit multicast traffic when there are no interested receives attached to a remote VTEP

DTo disallow IGMP request for the group 239.0.01 from host attached to the local VTEP
