Challenge your understanding of AWS Transit Gateway concepts, including its core functions, benefits, and common scenarios for network connectivity. This quiz helps validate your basic knowledge of cloud networking and Transit Gateway use cases.
Which primary function does a Transit Gateway provide in a cloud network environment?
Explanation: A Transit Gateway's main purpose is to act as a central hub and route traffic between multiple virtual cloud networks, improving scalability and simplifying network management. It does not serve as storage; that relates to file backup services. Hosting virtual machines is a function provided by compute services, not a networking hub. DNS management is handled by specialized services; Transit Gateway is focused on routing network traffic.
What type of connections can Transit Gateway support between resources?
Explanation: Transit Gateway supports connections between virtual networks, such as virtual private clouds, and extends connectivity such as VPN attachments. It does not connect only on-premise environments, nor is its scope limited to a single subnet. File storage synchronization is not within its networking focus; it deals with broader network connection management.
How does using a Transit Gateway change the way multiple networks connect to each other?
Explanation: Transit Gateway enables a hub-and-spoke topology, simplifying network architecture by avoiding the need for multiple direct connections. A complex web of direct connections is what happens without it, often leading to management challenges. It does not eliminate the need for security groups, which handle security at a different layer. Limiting connections to two networks is incorrect; it supports many-to-many connectivity.
In Transit Gateway architecture, what is an 'attachment' most commonly used for?
Explanation: An 'attachment' in this context refers to linking a virtual network or VPN to the Transit Gateway, creating a path for data to flow between them. Assigning compute resources and uploading files are outside the scope of network routing. Two-factor authentication is unrelated to network connectivity and pertains to security configurations elsewhere in the system.
Which feature allows administrators to manage how traffic is routed through a Transit Gateway?
Explanation: Route tables linked to the Transit Gateway define how traffic is directed between connected networks or VPNs. Adjusting dashboard access controls user interface permissions, not network flow. Log retention determines how long logs are kept, not how traffic moves. Monitoring CPU utilization relates to compute performance, not networking.
In an organization with ten separate virtual networks, what benefit does Transit Gateway offer?
Explanation: Transit Gateway gives a central hub for connections, greatly reducing the total number of direct links needed between networks. It does not affect storage limits or automatically upload data. Assigning public IP addresses is unrelated to Transit Gateway’s primary function, which focuses on efficient and scalable network connectivity.
How can Transit Gateway help connect a company’s virtual cloud environment with its on-premises infrastructure?
Explanation: Transit Gateway allows organizations to attach VPNs or dedicated connections, bridging cloud and on-premises resources efficiently. Copying databases does not provide ongoing network connectivity. Email filtering and file system mounting are application-level features, unrelated to network routing and management offered by Transit Gateway.
Why might a company choose to use Transit Gateway for its network connections?
Explanation: By centralizing network management, Transit Gateway can help minimize ongoing complexity and reduce operational costs. It does not increase the required payments; rather, it can lower them by simplifying network design. Restricting data transfer is not its goal. Automatic compliance report generation is handled by other specialized tools, not network gateways.
What is a common limitation to consider when connecting resources to a Transit Gateway?
Explanation: Transit Gateway imposes a maximum number of attachments to manage scalability and performance. It does not restrict attachment creation to one virtual network at a time, as multiple networks can be attached. Using the same subnet for all resources is not required. Attachments are not limited to weekends; they can be made anytime, subject to the maximum count.
A company wants to efficiently route traffic between different regions and its data center. Which network service feature should they consider?
Explanation: Inter-region peering and VPN attachments with a Transit Gateway are suitable for routing traffic between regions and on-premises data centers. Database replication and storage lifecycle rules relate to data management, not network routing. Enabling multi-factor authentication deals with account security and has no impact on network traffic routing between regions.
