A systems administrator has migrated a web application to the cloud with a synchronous uplink speed of 100Mbps. After the migration, the administrator receives reports of slow connectivity to the web application. The administrator logs into the firewall and notices the WAN port is transmitting at a constant 12.5MBps. Which of the following BEST explains the reason for the issue?
Answer(s): D
100Mbps = 12.5MBps. If we're transmitting a constant 12.5MBps out, people are fighting over bandwidth.
A user reports a poor-quality remote VDI session. Which of the following should the help desk technician do FIRST to troubleshoot the issue?
Answer(s): B
B. Ask the user if the client device or access location has changed.Before starting any troubleshooting process, it is always essential to gather information about the problem. Asking the user if anything has changed with the client device or access location is a quick way to identify if the issue is related to the user's connection or hardware. This step may eliminate unnecessary troubleshooting and provide insight into the root cause of the problem.
A systems administrator is examining a managed hosting agreement and wants to determine how much data would be lost if a server had to be restored from backups. To which of the following metrics should the administrator refer?
Answer(s): C
The metric to refer to determine how much data would be lost if a server had to be restored from backups is RPO (Recovery Point Objective). RPO is the maximum amount of data loss that is acceptable, measured in time. It indicates the point in time to which data must be restored after an outage, and therefore, how frequently backups should be taken to ensure that data loss is kept within acceptable limits.
A systems administrator for an e-commerce company will be migrating the company's main website to a cloud provider. The principal requirement is that the website must be highly available. Which of the following will BEST address this requirement?
A server cluster is a group of servers that are connected together and act as a single system. This means that if one server in the cluster fails, the other servers can take over and continue to provide service.Vertical scaling is the process of increasing the resources of a single server. This can be done by adding more RAM, CPU, or storage. However, vertical scaling can only be done up to a certain point. Once the server is maxed out, it cannot be scaled any further.Redundant switches are used to provide backup connectivity in case one switch fails. However, they do not provide any fault tolerance for the servers themselves.A next-generation firewall can help to protect the website from attacks, but it will not prevent the website from going down if one of the servers fails.Therefore, the best way to ensure that the website is highly available is to use a server cluster. This will provide redundancy and ensure that the website can continue to provide service even if one of the servers fails.
