A company is experiencing multiple switch failures. The network analyst discovers the following:Network recovery time is unacceptable and occurs after the shutdown of some switches.Some loops were detected in the network.No broadcast storm was detected.Which of the following is the most cost-effective solution?
Answer(s): C
Spanning Tree Protocol prevents and automatically resolves layer-2 loops without requiring new hardware. It also improves convergence times after a link or switch failure, meeting the recovery and loop-avoidance requirements most cost-effectively.
An architect needs to deploy a new payroll application on a cloud host. End users' access to the application will be based on the end users' role. In addition, the host must be deployed on the 192.168.77.32/30 subnet. Which of the following Zero Trust elements are being implemented in this design? (Choose two.)
Answer(s): A,C
Least privilege: Granting users access to the payroll app strictly according to their roles enforces the principle of least privilege.Microsegmentation: Placing the host in its own 192.168.77.32/30 subnet isolates it from other workloads, achieving microsegmentation.
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?
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.
A network administrator is troubleshooting an outage at a remote site. The administrator examines the logs and determines that one of the internet links at the site appears to be down. After the service provider confirms this information, the administrator fails over traffic to the backup link.Which of the following should the administrator do next?
Answer(s): D
After implementing the failover solution, you should confirm that all services and network paths are fully restored and operating correctly before closing the ticket.
A network architect is designing an expansion solution for the branch office network and requires the following business outcomes:Maximize cost savings with reduced administration overheadEasily expand connectivity to the cloudUse cloud-based services to the branch officesWhich of the following should the architect do to best meet the requirements?
Answer(s): A
By deploying SD-WAN you centrally manage and orchestrate all branch connections, minimizing administration overhead, while establishing direct, optimized tunnels into the cloud provider for low- latency, scalable access to cloud services.
