Question 1

A Solutions Architect is working with a customer which wants to extend their traditional Telco IP/MPLS core network to an NFV cloud.

Which NSX-T Data Center feature can be recommended by the architect? (Choose the best answer.)

ADistributed IDS

BEVPN

CLoad Balancer

DBGP

Answer : B

In NSX-T Data Center 3.0, EVPN is used to extend traditional Telco networks to NFV clouds:

- Telco virtual router use BPG to dynamically exchange tenant routing with NSX gateways.

- NSX gateways implement VRFs to provide isolation between tenants.

- NSX gateways support MP-BPG to interconnect Telco traditional networks with NSX virtual networks.

- VXLAN is the encaptulation supported to exchange traffic with the remote gateways.

Question 2

An NSX-T Architect is working in a brownfield environment with 4 ESXi hosts. These constraints were documented:

new servers cannot be purchased

North/South bandwidth must be guaranteed

Top-of-Rack switches have additional uplinks

Which three recommendations should the architect implement? (Choose three.)

ARemove one of the ESXi hosts and install a bare-metal Edge.

BUse a resource pool for production workloads.

CUse a resource pool to deploy the Edge nodes on.

DRecommend obtaining 2 new physical NICs for the servers.

EInstall Edge nodes on a separate cluster.

Answer : B, C, D

Question 3

An architect is designing a solution for containerization. The solution will include high availability and security using NSX-T Data Center. The architect plans to provide a basic required components list in the Logical Design.

Which solution should the architect recommend? (Choose the best answer.)

A3 NSX Managers, 3 virtual NSX Edges, two Tier-0 gateways in Active/Standby, BGP configuration

B2 NSX Managers, 2 virtual NSX Edges, one Tier-0 gateway, BGP configuration and a static route

C3 NSX Managers, 3 virtual NSX Edges, one Tier-0 gateway and a static route and OSPF

D1 NSX Manager, 2 virtual NSX Edges, two Tier-0 gateways in Active/Active, BGP configuration

Answer : A

Question 4

Which selection must be taken into consideration when creating a Logical Design for a planned migration? (Choose the best answer.)

AAn N-VDS can only attach to a single Overlay transport zone.

BAn N-VDS can only attach to a single VLAN transport zone.

CAn N-VDS can attach to both an Overlay and a VLAN transport zone to a N-VDS having different name/s.

DAn N-VDS must be disabled before attaching both Overlay and VLAN transport zones.

Answer : C

You can attach an N-VDS to both an Overlay and a VLAN transport zone, and you can do it also as with N-VDS having a different name or the same name. Single N-VDS can carry the traffic of both the Overlay transport zone and the VLAN transport zone. http://www.vmwarearena.com/how-to-create-nsx-t-transport-zone-vmware-nsx-t-part-7/#:~:text=So%20the%20transport%20zone%20is,and%20the%20VLAN%20transport%20zone.

Single N-VDS can carry the traffic of both the Overlay transport zone and the VLAN transport zone. http://www.vmwarearena.com/how-to-create-nsx-t-transport-zone-vmware-nsx-t-part-7/

Question 5

An architect is helping an organization with the Physical Design of an NSX-T Data Center solution.

This information was gathered during a workshop:

Some workloads should be moved to a Cloud Provider.

Extend network's VLAN or VNI across sites on the same broadcast domain.

Enable VM mobility use cases such as migration and disaster recovery without IP address changes.

Support 1500 byte MTU between sites.

Which selection should the architect include in their design? (Choose the best answer.)

ALoad Balancer

BReflexive NAT

CSSL VPN

DL2 VPN

Answer : D

Question 6

A customer has a requirement to implement a next generation firewall (NGFW) to improve security network introspection. The customer wants to apply the NGFW to all workloads exposed both internally and externally. The customer wants the NGFW to work seamlessly with NSX-T Data Center and vSphere.

Which solution should be recommended to the customer? (Choose the best answer.)

AUse network introspection only on the external workloads and use NSX DFW for internal workloads.

BApply the NGFW on bare metal hosts which will offer better performance of inline network introspection.

CApply the NGFW to internal and external workloads for increased protection and use NSX-T Data Center with Federation to set network policies.

DUse NSX-T Data Center leveraged with NSX Intelligence to protect all workloads at the network inspection level.

Answer : A

Question 7

An architect is helping an organization with the Conceptual Design of an NSX-T Data Center solution.

Which risk is documented by an architect? (Choose the best answer.)

AThe security team has a firewall communication matrix documented.

BThe team is not trained for NSX-T but have a very strong experience with vSphere.

COpen communication between different application tiers is not allowed.

DAggregate N-S throughput at any given time should be at least 10G.
