A network engineer needs to implement a cloud native solution. The solution must allow the recording of network conversation metadata of the host and appliances attached to a VPC. Which of the following will accomplish these goals with the least effort?
Enabling VPC (or equivalent) flow logs is the native, zero-agent way to capture metadata about every network conversation, source/destination IPs, ports, protocols, bytes transferred, across both hosts and managed appliances in your virtual network. It requires minimal setup (just a checkbox or API call) and scales automatically with your VPC.
A company is transitioning from on premises to a hybrid environment. Due to regulatory standards, the company needs to achieve a high level of reliability and high availability for the connection between its data center and the cloud provider. Which of the following solutions best meets the requirements?
By provisioning two dedicated Direct Connect circuits from separate carriers (diverse physical paths and providers), you achieve a true highly available, fault-tolerant link that meets stringent reliability and regulatory requirements without relying on the public internet.
A network security administrator needs to set up a solution to:
Gather all data from log files in a single location.
Correlate the data to generate alerts.
Which of the following should the administrator implement?
A Security Information and Event Management system centralizes log collection from disparate sources and applies correlation rules to generate actionable alerts.
A company is expanding its network and needs to ensure improved stability and reliability. The proposed solution must fulfill the following requirements:
Detection and prevention of network loops
Automatic configuration of ports
Standard protocol (not proprietary)
Which of the following protocols is the most appropriate?
The Spanning Tree Protocol (IEEE 802.1D) is a non-proprietary standard that automatically detects Layer 2 loops and dynamically places redundant switch ports into a blocking or forwarding state, ensuring loop prevention and automatic port configuration.
SIMULATION
A network administrator needs to resolve connectivity issues in a hybrid cloud setup. Workstations and VMs are not able to access Application A. Workstations are able to access Server B.
INSTRUCTIONS
Click on workstations, VMs, firewalls, and NSGs to troubleshoot and gather information. Type help in the terminal to view a list of available commands.
Select the appropriate device(s) requiring remediation and identify the associated issue(s).
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
Firewalls VPN tunnel down
The IPsec tunnel between on-prem Firewall 1 and cloud Firewall 2 (ipip0/ipip2) is down, so no traffic can traverse to the cloud.
Application NSG Misconfigured rule
There's a ''block'' rule for 10.3.9.0/24 192.2.1.0/24, preventing legitimate on-prem clients from reaching Application A.
