An administrator has been tasked with ensuring NC2 VMs are able to access Azure and on-premises resources. The NC2 VM traffic must not traverse the internet.
How can the administrator achieve this?

  1. By using an SSH connection
  2. By using an Interface Endpoint
  3. By using ExpressRoute
  4. By using a Site-to-Site VPN

Answer(s): C

Explanation:

Requirement Analysis: The NC2 VMs need to access Azure and on-premises resources without traversing the internet, ensuring secure and direct connectivity.
Solution Options:
SSH Connection: Suitable for individual remote access, not for full VM connectivity to Azure and on- premises resources.

Interface Endpoint: Facilitates private connectivity to specific Azure services, but not comprehensive for all resources.
ExpressRoute: Provides private, dedicated connectivity between Azure and on-premises environments. This ensures that traffic does not traverse the public internet, meeting the security and performance requirements.
Site-to-Site VPN: Provides secure connectivity but can involve traversing the internet, which is against the requirements.
Conclusion: ExpressRoute is the optimal solution as it offers a private connection that does not involve internet traversal, ensuring secure and efficient access to both Azure and on-premises resources.

An administrator is trying to determine which type of DNS server to deploy for a networking infrastructure in Azure.
Which DNS server option would require either VPN or ExpressRoute connectivity?

  1. Cloudflare
  2. Azure
  3. On-premises
  4. Google

Answer(s): C

Explanation:

DNS Server Options:
Cloudflare: A public DNS service that operates over the internet. Azure: Azure DNS operates within the Azure cloud and does not require VPN or ExpressRoute for connectivity within Azure.
On-premises: Requires a secure connection, such as VPN or ExpressRoute, to be accessible from Azure, as it resides outside the Azure cloud.
Google: Another public DNS service accessible over the internet.
Connectivity Requirements:
On-premises DNS: To integrate on-premises DNS with Azure, secure connectivity (VPN or ExpressRoute) is necessary to ensure seamless and secure communication between the on-premises infrastructure and Azure resources.
Conclusion: An on-premises DNS server would require VPN or ExpressRoute connectivity to be accessible and integrated with the Azure environment.

A nutanix user VPC called servers has three subnets called Tier1, tier2 and Darren-Tier3.
* Servers:10.0.0.0/16
* Tier1: 10.0.0.0/16
* Tier2: 10.0.0.0.128/25
* Darren-Tier3:10.0.4.0/24
An administrator wants to keep Darren-Tier3 isolated and not receive any outside traffic. In order properly route for Tier1 and Tier2 coming from native subnets for Azure, what should the ERP be set to?

  1. Transit VPC ERP set to 10.0.0.0/20 and Servers ERP set to 10.0.0.0/24
  2. Transit VPC ERP set to 10.0.0.0/16 and Servers ERP set to 10.0.0.0/25
  3. Transit VPC ERP set to 10.0.0.0/24 and Servers ERP set to 10.0.0.0/24
  4. Transit VPC ERP set to 10.0.0.0/16 and Servers ERP set to 10.0.4.0/24

Answer(s): D

Explanation:

ERP Configuration: ERP (External Route Prefix) settings determine how traffic is routed between subnets and VPCs.
Objective: The goal is to isolate Darren-Tier3 while ensuring proper routing for Tier1 and Tier2. Transit VPC ERP: Setting it to 10.0.0.0/16 ensures that it covers the entire VPC range, allowing traffic within Tier1 and Tier2.
Servers ERP: Setting it to 10.0.4.0/24 ensures isolation for Darren-Tier3 by limiting traffic to that specific subnet and preventing external traffic from reaching it. Conclusion: This configuration achieves the isolation of Darren-Tier3 while allowing proper routing for Tier1 and Tier2.

An administrator is planning to expand an NC2 on Azure cluster.
Which statement is true regarding prerequisites for expanding the cluster?

  1. Cluster must be in a Cluster Stopped state.
  2. Cluster must have at least three nodes.
  3. Cluster must be in a Cluster Connected state.
  4. Cluster must have at least five nodes.

Answer(s): C

Explanation:

Cluster State Requirement: To expand a cluster, it must be operational and in a connected state to ensure seamless integration of additional nodes.
Cluster Stopped State: If the cluster is stopped, it cannot perform expansion operations. Minimum Nodes Requirement: There is no minimum node count prerequisite for expanding the cluster as long as the cluster is connected.
Cluster Connected State: Ensuring the cluster is connected verifies that it is operational and can communicate with additional nodes being added.
Conclusion: The cluster must be in a Cluster Connected state to expand successfully.
