VMware VMware Certifications 3V0-41.19 Questions & Answers

• Question 41:

  An architect is helping an organization with the Logical Design of an NSX-T Data Center solution. This information was gathered during the Assessment Phase:

  1.

  Customer Is concerned with NSX Manager availability.

  2.

  3 cabinets/racks are available in the data center.

  3.

  No integration with 3rd party solution is required.

  4.

  There is no budget for physical equipment acquisition.

  5.

  The 3 cabinets/racks do not share the same L2 domain.

  Which three should the architect include in their design to address the customer's concern with NSX Manager availability? (Choose three.)

  A. Use another NSX Manger IP in case an appliance falls.

  B. Deploy 2 cold standby NSX Manager appliances in rack 2/3.

  C. Deploy an NSX Manager Appliance per rack and cluster them.

  D. Use a physical/internal load-balancer with the cluster.

  E. Use separate IP per NSX Manager appliance per rack.

  F. Deploy a single active NSX Manager appliance in rack 1.

  Correct Answer: CDE

  Customer is concerned with availability and NSX-T requires (except for labs)a 3x Mgr cluster must be deployed. You can use internal HA/VIPand vSphere HA for Mgmt cluster only when the mgrs. are on the same L2 domain.To do this you need an external load-balancer, the only one that would meet the "no 3rd party" and "no physical equipment acquisition" would be a NSX-T Edge LB though the only answer that lines up with that is (D) and its worded poorly. (F) and (B) are both wrong/worded even more poorly. (A) by itself isn't right/wrong but when also looking at (E) then you know it doesn't cut it. (C and E) are correct. https://docs.vmware.com/en/VMware-NSX-T-Data-Center/2.4/installation/GUID-72A55651-0031-43A49F23-5950C1AFF304.html https://vxplanet.com/2020/03/26/using-nsx-t-loadbalancer-for-the-nsx-t-management-cluster-part-1/ https://vxplanet.com/2020/03/26/using-nsx-t-loadbalancer-for-the-nsx-t-management-cluster-part-2/

• Question 42:

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

  1.

  This information was gathered during a workshop:

  2.

  Some workloads should be moved to a Cloud Provider.

  3.

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

  4.

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

  5.

  Support 1500 byte MTU between sites.

  Which should the architect include in their design?

  A. SSL VPN

  B. Reflexive NAT

  C. L2 VPN

  D. Load Balancer

  Correct Answer: C

  NSX-T doesn't support sslvpn, reflexive NATand LB don't solve the ask. L2VPN will stretch across sites and to Cloud Providers.

• Question 43:

  Which three assessment findings are part of a Conceptual Design? (Choose three.)

  A. assumptions

  B. vendor model

  C. justifications

  D. constraints

  E. host names

  F. risks

  Correct Answer: ADF

  Conceptual Design is RRCA (requirements, risks, constraints,and assumptions)

• Question 44:

  An architect is helping an organization with the Logical Design of an NSX-T Data Center solution. This information was gathered during the Assessment Phase:

  1.

  There Isn't much budget available for a new off-shore site.

  2.

  The new site is decentralized and no communication with the main data center is required.

  3.

  The design will need to cater for availability, upgrades, and failure scenarios.

  Which three should the architect recommend In their design? (Choose three.)

  A. Collapse the Management/Edge/Compute cluster.

  B. A Shared Edge/Management cluster and one for Compute.

  C. Separate the hosts physical NICs for VSS and N-VDS.

  D. Install a minimum 4 ESXi hosts In the site.

  E. Make all pNICs part of N-VDS and VMKs will be migrated.

  F. Install a minimum of 6 ESXi hosts in the site.

  Correct Answer: ACD

  Limited budget for new site means collapsing of mgmt., edge, and compute provides the best value at lowest cost. NSX-T can fully operate with 4 esxi hosts (no need for 6) as that is more a requirement of VCF/vSAN. Because you are running NSX Edges you should run a vSS or vDS for vmkerneland edge traffic and a N-vDS for NSX-T overlays traffic. Each vSwitch requiring its own set of pNics https:// blogs.vmware.com/networkvirtualization/2018/10/flexible-deployment-options-for-nsx-t- edge-vm.html/

• Question 45:

  An NSX-T architect is working with a customer who wants to improve performance and future-proof their workloads with a multi-site architecture. A current-state analysis captured this information:

  1.

  Latency between sites Is 160ms.

  2.

  Bandwidth is 2Gbps.

  3.

  The MTU is 1600.

  What two VMware design recommendations should the architect recommend to the organization to

  achieve future-proofing? (Choose two.)

  A. Latency must be less than 150ms.

  B. Bandwidth must be at least 10Gbps.

  C. MTU is recommended to be 9000.

  D. MTU must be at least 1700.

  E. Latency RTT is acceptable.

  Correct Answer: AC

• Question 46:

  Which is associated with the Discover Task of the Engagement Lifecycle?

  A. Create and document the logical and virtual design.

  B. Gather and document requirements, assumptions and constraints.

  C. Build, deploy, implement and test the design.

  D. Measure performance against customer's requirements.

  Correct Answer: B

  Discovery is part of the initial conceptual design (RRCA)

• Question 47:

  An architect is helping an organization with the Logical Design of an NSX-T Data Center solution. This information was gathered during the Assessment Phase:

  1.

  Maximum performance and availability is required between the physical and virtual network.

  2.

  Load Balancing service is required for back-end web servers.

  3.

  NAT is required.

  Which should the architect include in their design?

  A. Deploy a Tler-1 gateway and connect It to an Active/Active Tier-0 gateway with ECMP configured.

  B. Deploy an Active/Active Tier-0 gateway and configure ECMP.

  C. Create two separate VLANs to connect the Tier-0 gateway upstream traffic and configure ECMP.

  D. Deploy an Active/Passive Tier-0 gateway and configure ECMP.

  Correct Answer: A

  Option A is required (even though BandC are technically correct for parts of the requirement).

  Stateful services (LB) can't be on the same gateway as ECMPgateway.

• Question 48:

  Which three must be taken into consideration when creating a Logical Design for a planned migration? (Choose three.)

  A. A transport node can attach single VLAN transport zones with single N-VDS.

  B. An N-VDS with the same name can be attached to both Overlay and VLAN transport zones.

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

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

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

  F. An N-VDS can only attach to a multiple VLAN transport nodes.

  Correct Answer: BDF

  Transport Zone 101 w/ NSX-T

• Question 49:

  An architect is helping an organization with the Physical Design of an NSX-T Data Center solution and resolving a network throughput bottleneck. This information was gathered during a workshop:

  1.

  A VM running a business critical application Is peaking at ~5Gbps

  2.

  Current host uplink is configured as Active/Standby with two 10Gb NICs.

  3.

  The installed server NIC model does not support GENEVE offload.

  4.

  All VM traffic is East/West.

  5.

  The business critical application VM communicates with multiple client VMs.

  Which should the architect recommend to improve vSphere VM throughput?

  A. Configure the Transport Node Uplink Profile to use a Load Balance Source teaming policy with two active uplinks.

  B. Deploy an additional Edge Node to the Edge Node Cluster.

  C. Replace the existing network switches and routers with newer higher-performance.

  D. Replace the existing NICs with a model that supports GENEVE offload.

  Correct Answer: D

  (D) will perform the necessary offload to greatly improve performance. The 5GBps isn't saturating the actual pNIC, and while switching the uplink to active/active will help some, the issue will come back during a pNIC failure.

• Question 50:

  Which NSX-T feature is used to allocate the network bandwidth to business-critical applications and to resolve situations where several types of traffic compete for common resources?

  A. LAG Uplink Profile

  B. Transport Node Profiles

  C. LLDP Profile

  D. Network I/O Control Profiles

  Correct Answer: D

  https://docs.vmware.com/en/VMware-NSX-T-Data-Center/2.2/com.vmware.nsxt.install.doc/GUID9A8FD62A-F099-4329-8220-6D5853F9A62D.html Use the Network I/O Control (NIOC) profile to allocate the network bandwidth to business-critical applications and to resolve situations where several types of traffic compete for common resources. NIOC profile introduces a mechanism to reserve bandwidth for system traffic based on the capacity of the physical adapters on a host. Version 3 of the Network I/O Control feature offers improved network resource reservation and allocation across the entire switch. Network I/O Control version 3 for NSX-T supports resource management of system traffic related to virtual machines and to infrastructure services, such as vSphere Fault Tolerance, and so on. System traffic is strictly associated with an vSphere ESXi host.
