Question 1

A developer reports errors when trying to access a web application. The developer uses Postman to troubleshoot and receives the following error:

Which of the following is the cause of the issue?



Answer : B

The 403 Forbidden HTML response indicates the API is rejecting the call due to missing or invalid credentials (no valid access key/signature), not because of a missing resource (404), a networklevel block (you'd see a timeout or TCP reject), or an HTTP redirect. Proper authentication headers with a valid signature are required to avoid the 403 error.


Question 2

A network engineer is working on securing the environment in the screened subnet. Before penetration testing, the engineer would like to run a scan on the servers to identify the OS, application versions, and open ports. Which of the following commands should the engineer use to obtain the information?



Answer : B

The -A flag enables aggressive scanning, which combines OS detection, version detection, script scanning, and traceroute to give you detailed information on hosts in the 10.10.10.0/28 range.


Question 3

An outage occurred after a software upgrade on core switching. A network administrator thinks that the firmware installed had a bug. Which of the following should the network administrator do next?



Answer : B

Before taking corrective action, you need to verify that the new firmware is indeed the root cause, such as by rolling back to the previous version in a controlled test or reproducing the failure in a lab, so you're sure your fix addresses the actual problem.


Question 4

A network architect needs to design a solution to ensure every cloud environment network is built to the same baseline. The solution must meet the following requirements:

Use automated deployment.

Easily update multiple environments.

Share code with a community of practice.

Which of the following are the best solutions? (Choose two.)



Answer : A, B

CI/CD pipelines: Automate the provisioning and configuration of network baselines across all environments, and make it easy to roll out updates consistently.

Public code repository: Enables your community of practice to collaborate, review, and contribute to shared IaC modules and templates, while making updates discoverable and reusable.


Question 5

A network architect is creating a network topology for a global SD-WAN deployment. The business has offices in Asia, Europe, and the United States and makes use of data centers in the United States and Europe. Most traffic between sites must have the lowest latency possible. Which of the following topologies best meets this requirement?



Answer : C

A full-mesh SD-WAN topology allows each site to establish direct overlays with every other site, minimizing the number of hops and avoiding backhauling through a central hub, thereby delivering the lowest latency paths between Asia, Europe, and the US.


Question 6

A cloud architect must recommend an architecture approach for a new medical application that requires the lowest downtime possible. Which of the following is the best application deployment strategy given the high-availability requirement?



Answer : A

Deploying active-active clusters across two AZs in each of two regions ensures the application can survive both AZ- and entire-region failures, delivering the highest possible uptime.


Question 7

A network administrator is troubleshooting a user's workstation that is unable to connect to the company network. The results of commands the administrator runs on the workstation are shown below:

A router on the same network shows the following output:

Which of the following is the most likely cause of the issues?



Answer : B
