Server A (10.2.3.9) needs to access Server B (10.2.2.7) within the cloud environment since they are segmented into different network sections. All external inbound traffic must be blocked to those servers. Which of the following need to be configured to appropriately secure the cloud network? (Choose two.)

• Network security group rule:allow 10.2.3.9 to 10.2.2.7
• Network security group rule:allow 10.2.0.0/16 to 0.0.0.0/0
• Network security group rule:deny 0.0.0.0/0 to 10.2.0.0/16
• Firewall rule:deny 10.2.0.0/16 to 0.0.0.0/0
• Firewall rule:allow 10.2.0.0/16 to 0.0.0.0/0
• Network security group rule:
• deny 10.2.0.0/16 to 0.0.0.0/0

A cloud network engineer needs to enable network flow analysis in the VPC so headers and payload of captured data can be inspected. Which of the following should the engineer use for this task?

• Syslog service
• Traffic mirroring
• Network flows

A company provides an API that runs on the public cloud for its customers. A fixed number of VMs host the APIs. During peak hours, the company notices a spike in usage that results in network communication speeds slowing down for all customers. The management team has decided that access for all customers should be fair and accessible at all times. Which of the following is the mostcost-effective way to address this issue?

• Use an allow list for customers using APIs.
• Increase the number of VMs running APIs.
• Enable throttling on APIs.
• Increase the MTU on the VMs.

A network administrator recently deployed new Wi-Fi 6E access points in an office and enabled 6GHz coverage. Users report that when they are connected to the new 6GHz SSID, the performance is worse than the 5GHz SSID. The network administrator suspects that there is a source of 6GHz interference in the office. Using the troubleshooting methodology, which of the following actions should the network administrator do next?

• Test to see if the changes have improved network performance.
• Use a spectrum analyzer and check the 6GHz spectrum.
• Document the list of channels that are experiencing interference.
• Change the channels being used by the 6GHz radios in the APs.

A network engineer adds a large group of servers to a screened subnet and configures them to use IPv6 only. The servers need to seamlessly communicate with IPv4 servers on the internal networks. Which of the following actions is the best way to achieve this goal?

• Add IPv6 to the network cards on the internal servers so they can communicate with the screened subnet.
• Set up a bridge between the screened subnet and internal networks to handle the conversion.
• Change the servers in the screened subnet from IPv6 addresses to IPv4 addresses.
• Implement NAT64 on the router between the screened subnet and the internal network.

Throughout the day, a sales team experiences videoconference performance issues when the accounting department runs reports. Which of the following is the best solution?
