Objective 1.3
N10-009Summarize cloud concepts and connectivity options.
Objective 1.3 sits in Networking Concepts, which carries 23% of the Network+ exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A network administrator deploys virtual machines in a virtual network that must reach the internet but must not accept unsolicited inbound connections. Which connectivity option satisfies this requirement?
Correct.
Checked against cloudflare.com, July 2026Concept
Cloud gateways manage how resources in a virtual network reach and are reached from the internet, with different gateway types offering outbound-only or bidirectional access.
Why A
A NAT gateway lets resources initiate outbound internet connections while remaining unreachable from unsolicited inbound traffic, matching the stated requirement exactly.

Microsoft Learn: Azure Virtual Network overview, checked July 2026All resources in a virtual network can communicate outbound with the internet, by default. You can also use a public IP address, NAT gateway, or public load balancer to manage your outbound connections. You can communicate inbound with a resource by assigning a public IP address or a public load balancer.
Now you: objective 1.3 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
A cloud engineer needs two virtual networks located in different regions to communicate directly with each other, without routing traffic through an on-premises VPN device. Which connectivity option should be configured?
Sample question 2 of 3
A developer working from a home office must test code against resources inside a company virtual network using only a personal laptop, without configuring any on-premises VPN hardware. Which connectivity option should be used?
Sample question 3 of 3
A network engineer already filters subnet traffic by source IP and port using network security groups but must also add a virtual firewall that performs deep packet inspection inside the virtual network. Which resource should be deployed?
