   Which of the following would be used to adjust resources dynamically for a virtual web server under variable loads?

   • AElastic computing
   • BScalable networking
   • CHybrid deployment
   • DMultitenant hosting

   Show answer

   Answer: A

   Explanation

   A. Elastic computing would be used to adjust resources dynamically for a virtual web server under variable loads. Elastic computing involves the allocation of resources on demand, so that the resources available to a virtual web server can be increased or decreased as needed in order to handle varying levels of traffic or demand. This can help to ensure that the web server has the resources it needs to handle any workload, without wasting resources when demand is low. Scalable networking refers to the ability of a network to expand or contract as needed in order to meet changing demand. Hybrid deployment involves the use of a combination of on-premises and cloud-based resources. Multitenant hosting involves the use of a single instance of a software application to serve multiple customers, each with their own customized version of the application.

   A technician discovered that some information on the local database server was changed during a file transfer to a remote server. Which of the following should concern the technician the MOST?

   • AConfidentiality
   • BIntegrity
   • CDDoS
   • DOn-path attack

   Show answer

   Answer: B

   Explanation

   The technician should be concerned the MOST about integrity1. Integrity is the property of data that ensures it is accurate, complete, and consistent. When information on the local database server is changed during a file transfer to a remote server, it means that the integrity of the data has been compromised. This could be due to a malicious attack, a network error, a software bug, or a human mistake. The technician should investigate the cause of the data change and take appropriate measures to restore the integrity of the data and prevent future incidents.

4. Question 194 · 871 in bank

   During a client audit, a network analyst is tasked with recommending changes to upgrade the client network and readiness. A field technician has submitted the following report:

   

   Based on this report, which of the following metrics or sensors would be the BEST recommendation to the client?

   • AElectrical
   • BHumidity
   • CFlooding
   • DTemperature

   Show answer

   Answer: D

   Explanation

   Based on the report, the BEST recommendation to the client would be to monitor temperature. The report mentions poor ventilation in the space where the IT closet and storage room are located. This suggests that there may be a risk of overheating, which could have negative impacts on the performance and health of the network equipment. Monitoring temperature can help detect and prevent overheating, which can improve the reliability and lifespan of the equipment. While humidity and flooding can also be important to monitor in certain environments, they are not specifically mentioned in the report and may not be as pressing of an issue in this case. Electrical monitoring may be useful for detecting power surges or other electrical issues, but it is not directly related to the issues mentioned in the report.

   After HVAC failures caused network outages, the support team decides to monitor the temperatures of all the devices. The network administrator cannot find a command that will display this information. Which of the following will retrieve the necessary information?

   • ASNMP OID values
   • BNetFlow data export
   • CNetwork baseline configurations
   • DSecurity information and event management

   Show answer

   Answer: A

   Explanation

   An OID is an object identifier value, typically an address used to identify a particular device and its status. For example, you want to monitor a remote temperature sensor sitting on the roof of your building. But there are three different temperature sensors placed in different parts of the roof. How can you check the value of the sensor located on the eastern side of the roof? Using the unique OID associated with each device. In other words, each device has its own unique OID and using that you can track the performance and status of that particular device.

7. Question 197 · 871 in bank

   A company needs a redundant link to provide a channel to the management network in an incident response scenario. Which of the following remote access methods provides the BEST solution?

   • AOut-of-band access
   • BSplit-tunnel connections
   • CVirtual network computing
   • DRemote desktop gateways

   Show answer

   Answer: A

   Explanation

   Out-of-band access provides the BEST solution for redundant link and management network access in an incident response scenario. Out-of-band access is a remote access method that allows administrators to connect to network devices through a dedicated, separate network, rather than through the production network. This provides a redundant link and a secure channel to access the management network, which is essential during incident response scenarios. Out-of-band access also allows administrators to remotely manage and troubleshoot network devices, even if the production network is down.
