An administrator needs to allow communication between several VPCs without requiring to configure routes in the physical network or using a dynamic routing protocol like BGP.
How should the administrator satisfy this requirement?
Correct Answer:
D
Explanation
A Transit VPC acts as a central hub that connects multiple VPCs together, allowing inter-VPC communication without needing physical network routes or BGP. Traffic flows through the transit VPC as an intermediary. Other options like mesh topologies or direct peering would either require more configuration or BGP setup. A transit VPC model is the simplest way to achieve multi-VPC connectivity in Nutanix Flow without dynamic routing protocols.
An administrator recently deployed a new set of virtual machines... 3-tier web application... restricted as follows:
Only application VMs can talk to database VMs on port 3306
Frontend VMs should only communicate with application VMs on port 8080
Which action will correctly create and configure the Security Policies in Nutanix Flow to satisfy this task?
Correct Answer:
D
Explanation
Creating categories for each tier (frontend, application, database) and then defining an application policy between them lets you specify which tiers communicate on which ports. This approach uses Flow's microsegmentation capabilities to enforce port-level restrictions. Other methods like subnet-based policies would be too broad and allow all traffic between tiers. Categories provide the granularity needed to enforce the 3306 and 8080 port restrictions described.
An administrator has just added a new VPC for Tenant-B... However, users are reporting that they are unable to access external resources from VMs created in the Tenant-B-Prod subnet.
What should be done to correct the problem?
Correct Answer:
A
Explanation
External Route Policies (ERPs) define how traffic from a VPC reaches external networks and the internet. If VMs cannot access external resources after a new VPC is created, the ERP entries for that VPC need to be configured or updated to specify the routes for outbound traffic. Without proper ERP configuration, the VPC lacks the routing rules needed to reach destinations outside the virtual network.
A service-insertion firewall VM protects user VMs access to the internet. The virtual and physical switches, as well as all user VMs, currently use the default MTU size of 1500.
Everything functions normally until a user VM is migrated to another host. After the migration, the user reports that some websites fail to load while ping to those same sites still succeeds. Routing and security policies appear normal.
Which two configuration changes could resolve the issue? (Choose two.)
Correct Answer:
A, D
Explanation
Service insertion adds overhead to packets, increasing required MTU size beyond the default 1500. When a VM migrates to a host with standard 1500 MTU configuration while traversing a service insertion firewall path, packets get fragmented or dropped depending on the DF bit setting. Increasing MTU on both vSwitches and the vNIC to 1558 or higher accommodates the firewall's encapsulation overhead. Ping works because ICMP often fragments differently than application traffic. The other answers about routing and security policies being normal confirm MTU is the issue.
An administrator has deployed a microsegmentation policy in Nutanix Flow that allows certain VM traffic based on Active Directory (AD) user group membership.
Users in a specific AD group report they are unable to access the VMs, while other users can connect without issues. The administrator suspects the problem is related to identity-based policy mapping.
What should the administrator do to troubleshoot and resolve the access issue related to the identity-based policy?
Correct Answer:
D
Explanation
Identity-based policies in Flow rely on accurate Active Directory group membership mapping. If specific AD group members cannot access VMs while others can, the issue is that those affected users are either not in the mapped AD group or the group membership is incorrect. Verifying AD group membership confirms whether the identity policy is mapped to the right group and whether those users are actually members. This directly addresses the identity-based policy troubleshooting needed here.
An administrator is deploying a new multi-tenant environment in Prism Central and has created a VPC named TenantVPC1.
The administrator needs to enable external connectivity for this VPC so that some services inside the VPC can be accessed from the corporate network without NAT translation, while other services require Internet access through SNAT translation. The administrator plans to use an External Network(s) to provision this connectivity.
Which configuration should the administrator apply to satisfy this requirement?
Correct Answer:
A
Explanation
The requirement needs two different connectivity paths with different NAT behaviors. A NAT external network translates addresses for internet access while a Routed or No-NAT external network allows direct connectivity for corporate network access without address translation. Attaching both external networks to the single VPC provides the flexibility to route different service traffic through different paths based on destination. A single external network cannot provide both NAT and non-NAT translation simultaneously.
