A network architect needs to build a new data center for a large company that has business units that process retail financial transactions. Which of the following information should the architect request from the company?

1. A. Regulatory requirements
2. B. Statement of work
3. C. Business case study
4. D. Internal reference architecture

Correct Answer: A
Before designing a facility that will handle retail financial transactions, you need to understand all applicable compliance and security mandates (e.g. PCI DSS, SOX, GDPR). Those regulatory requirements will drive your choices around physical security, network segmentation, encryption, logging, redundancy, and operational controls, ensuring the data center meets its legal and industry-specific obligations.

A company just launched a cloud-based application. Some users are reporting the application will not load. A cloud engineer investigates the issues and reports the following:
* Not all users are experiencing the issue.
* The application infrastructure is optimal.
* Users experiencing the issue belong to the company's remote sales team. Which of the following is most likely misconfigured?

1. A. Application load balancers
2. B. Ports and protocols
3. C. IP addressing
4. D. Geolocation rules

Correct Answer: D
Since only the remote sales team is affected and the infrastructure and network settings are correct, it??s most likely that your geolocation or geo-restriction policies are blockingtraffic from the regions where those users are located. Correcting those rules to allow their locations should restore access without impacting other users.

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 solutionsbestmeets the requirements?

1. A. Establish a Direct Connect with the cloud provider and peer to two different VPCs in the cloud network.
2. B. Establish a Direct Connect with the cloud provider and a redundant connection with a VPN over the internet.
3. C. Establish two Direct Connect connections to the cloud provider using two different suppliers.
4. D. Establish a VPN with two tunnels to a transit gateway at the cloud provider.

Correct Answer: C
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 company is experiencing Wi-Fi performance issues. Three Wi-Fi networks are available, each running on the 2.4 GHz band and on the same channel. Connecting to each Wi-Fi network yields slow performance. Which of the following channels should the networks be configured to?

1. A. Channel 1, Channel 2. and Channel 3
2. B. Channel 2. Channel 4, and Channel 9
3. C. Channel 1, Channel 6, and Channel 11
4. D. Channel 3, Channel 5, and Channel 10

Correct Answer: C
These are the three non-overlapping channels in the 2.4 GHz band, eliminating co-channel and adjacent-channel interference for optimal Wi-Fi performance.

A SaaS company's new service currently is being provided through four servers. The company's end users are having connection issues, which is affecting about 25% of the connections. Which of the following ismostlikely the root cause of this issue?

1. A. The service is using round-robin load balancing through a DNS server with one server down.
2. B. The service is using weighted load balancing with 40% of the traffic on server A, 20% on server B, 20% on server C, and server D is down.
3. C. The service is using a least-connection load-balancing method with one server down.
4. D. Load balancing is configured with a health check in front of these servers, and one of these servers is unavailable.

Correct Answer: A
With simple round-robin DNS distributing 25% of requests to each of four servers, a single server outage directly causes exactly 25% of connections to fail, matching the reported impact.
