  Which of the following storage types should the administrator deploy?

  A. Spinning disks

  B. NVMe

  C. SSD

  D. Hybrid

  Correct Answer: B

• Question 32:

  A cloud solutions architect has an environment that must only be accessed during work hours. Which of the following processes should be automated to BEST reduce cost?

  A. Scaling of the environment after work hours

  B. Implementing access control after work hours

  C. Shutting down the environment after work hours

  D. Blocking external access to the environment after work hours

  Correct Answer: C

  One of the main benefits of cloud computing is that you only pay for the resources that you use. However, this also means that you need to manage your cloud resources efficiently and avoid paying for idle or unused resources1. Shutting down the environment after work hours is a process that can be automated to best reduce cost in a cloud environment that must only be accessed during work hours. This process involves stopping or terminating the cloud resources, such as virtual machines, databases, load balancers, etc., that are not needed outside of the work hours. This can significantly reduce the cloud bill by avoiding charges for compute, storage, network, and other services that are not in use2. The other options are not the best processes to automate to reduce cost in this scenario: Option A: Scaling of the environment after work hours. Scaling is a process that involves adjusting the number or size of cloud resources to match the demand or workload. Scaling can be done manually or automatically using triggers or policies. Scaling can help optimize the performance and availability of a cloud environment, but it does not necessarily reduce the cost. Scaling down the environment after work hours may reduce some costs, but it may still incur charges for the remaining resources. Scaling up the environment before work hours may increase the cost and also introduce delays or errors in provisioning new resources3. Option B: Implementing access control after work hours. Access control is a process that involves defining and enforcing rules and policies for who can access what resources in a cloud environment. Access control can help improve the security and compliance of a cloud environment, but it does not directly affect the cost. Implementing access control after work hours may prevent unauthorized access to the environment, but it does not stop or terminate the resources that are still running and consuming cloud services4. Option D: Blocking external access to the environment after work hours. Blocking external access is a process that involves restricting or denying network traffic from outside sources to a cloud environment. Blocking external access can help protect the environment from potential attacks or breaches, but it does not impact the cost. Blocking external access after work hours may prevent unwanted requests or connections to the environment, but it does not shut down or release the resources that are still active and generating cloud charges.

• Question 33:

  An organization was preparing to harden an environment before granting access to external auditors. Vulnerability testing was completed, and only one low-priority, informational vulnerability remained outstanding:

  

  Two weeks later, the auditors review the system on a new machine without an existing browser cache. Credentials are not required when accessing the application login page. Which of the following tests were skipped, causing this issue?

  A. Functionality testing

  B. Usability testing

  C. Regression testing

  D. Penetration testing

  Correct Answer: C

• Question 34:

  Which of the following enables CSPs to offer unlimited capacity to customers?

  A. Adequate budget

  B. Global data center distribution

  C. Economies of scale

  D. Agile project management

  Correct Answer: C

• Question 35:

  A cloud administrator is reviewing the current private cloud and public law environment, and is building an optimization plan. Portability is of great concern for the administrator so resources can be easily moved from one environment to another.

  Which of the following should the administrator implement?

  A. Serverless

  B. CDN

  C. Containers

  D. Deduplication

  Correct Answer: C

• Question 36:

  A systems administrator is writing a script for provisioning nodes in the environment. Which of the following would be BEST for the administrator to use to provision the authentication credentials to the script?

  A. password='curl https://10.2.3.4/api/sytemops?op=provision'

  B. password=$env_password

  C. password=$(cat /opt/app/credentials)

  D. password="MyS3cretP4sswordIsVeryL0ng"

  Correct Answer: B

• Question 37:

  A systems administrator is configuring a storage system for maximum performance and redundancy. Which of the following storage technologies should the administrator use to achieve this?

  A. RAID 5

  B. RAID 6

  C. RAID 10

  D. RAID 50

  Correct Answer: C

  The best storage technology to configure for maximum performance and redundancy is RAID 10 (Redundant Array of Independent Disks 10). RAID 10 is a combination of RAID 1 (mirroring) and RAID 0 (striping) that provides both fault

  tolerance and improved performance. RAID 10 divides and replicates the data across multiple disks in pairs, creating mirrored sets, and then stripes the data across those sets, creating a striped set. RAID 10 can withstand multiple disk

  failures as long as they are not in the same mirrored set, and can also increase the read and write speed by parallelizing the disk operations.

• Question 38:

  A systems administrator has verified that a physical switchport that is connected to a virtualization host is using all available bandwidth. Which of the following would BEST address this issue?

  A. Port mirroring

  B. Link aggregation

  C. Spanning tree

  D. Microsegmentation

  Correct Answer: B

  Link aggregation, often referred to as "bonding" or "teaming," combines multiple physical network links into a single logical link. This provides increased bandwidth, fault tolerance, and load balancing. In the context of a virtualization host using all available bandwidth, implementing link aggregation would allow the host to utilize the combined bandwidth of multiple physical links, thus alleviating congestion and ensuring efficient use of network resources. This can significantly improve network performance for the virtualized environment.

• Question 39:

  A systems administrator needs to implement a security control that will prevent unknown malware from infecting a system in case the antivirus solution fails. Which of the following should the administrator implement?

  A. A software whitelist

  B. File integrity monitoring

  C. A host-based IDS

  D. Hardened baselines

  Correct Answer: A

• Question 40:

  A web application has been configured to use auto-scaling for provisioning and deprovisioning more VMs according to the workload. The systems administrator deployed a new CI/CD tool to automate new releases of the web application. During the night, a script was deployed and configured to be executed by the VMs during bootstrapping. Now, the auto-scaling configuration is creating a new VM every five minutes.

  Which of the following actions will MOST likely resolve the issue?

  A. Reducing the maximum threshold in the auto-scaling configuration

  B. Debugging the script and redeploying it

  C. Changing the automation tool because it is incompatible

  D. Modifying the script to shut down the VM after five minutes

  Correct Answer: B

  The best way to resolve the issue where the autoscaling configuration is creating a new VM every five minutes after deploying a new CI/CD tool to automate new releases of the web application and configuring a script to be executed by the

  VMs during bootstrapping is to debug the script and redeploy it. Debugging the script means finding and fixing any errors or bugs in the code or logic of the script that may cause unexpected or undesired behavior, such as triggering the

  autoscaling condition or failing to complete the bootstrapping process. Redeploying the script means updating or replacing the existing script with the corrected or improved version of the script.
