• Question 193:

  A systems administrator is planning a penetration test for company resources that are hosted in a public cloud. Which of the following must the systems administrator do FIRST?

  A. Consult the law for the country where the company's headquarters is located
  B. Consult the regulatory requirements for the company's industry
  C. Consult the law for the country where the cloud services provider is located
  D. Consult the cloud services provider's policies and guidelines
  D. Consult the cloud services provider's policies and guidelines

  ---

  Explanation

  The first thing that the systems administrator must do before planning a penetration test for company resources that are hosted in a public cloud is to consult the cloud services provider's policies and guidelines. Penetration testing is a type of security assessment that involves simulating an attack on a system or network to identify vulnerabilities and weaknesses. However, not all cloud services providers allow penetration testing on their platforms, or they may have specific rules and requirements for conducting such tests. The systems administrator should check the cloud services provider's policies and guidelines and obtain their permission and approval before performing any penetration testing.

• Question 194:

  A systems administrator is responsible for upgrading operating systems on VMs that are hosted in a cloud environment. The systems administrator wants to ensure the VMs receive updates for as long as possible. Which of the following should the systems administrator choose?

  A. Stable
  B. Nightly
  C. LTS
  D. Canary
  E. EDR
  C. LTS

• Question 195:

  A software company recently moved all of its development testing to a public cloud environment. The company primarily uses IaaS to deploy and test its code. The company needs the software developers to be more agile and efficient when testing application code. Which of the following backup types should the developers use to BEST ensure the speedy recovery of a system if it is damaged?

  A. Snapshots
  B. Full
  C. Incremental
  D. Differential
  C. Incremental

  Explanation

• Question 196:

  A systems administrator is deploying a VM and would like to minimize storage utilization by ensuring the VM uses only the storage if needs. Which of the following will BEST achieve this goal?

  A. Compression
  B. Deduplication
  C. RAID
  D. Thin provisioning
  D. Thin provisioning

  ---

  Explanation

  Thin provisioning is the technique that will minimize storage utilization by ensuring the VM uses only the storage it needs. Thin provisioning is a storage allocation method that assigns disk space to a VM on demand, rather than in advance. Thin provisioning can improve storage utilization and efficiency by avoiding overprovisioning and wasting disk space. Thin provisioning can also allow for more flexibility and scalability of storage resources.

• Question 197:

  A database system is causing performance issues due to an increase in the number of transactions. Which of the following is the best way to solve these performance issues?

  A. Changing to object storage.
  B. Adding more volume storage.
  C. Increasing storage IOPS.
  D. Configuring RAID.
  C. Increasing storage IOPS.

  ---

  Explanation

  C. Increasing storage IOPS: IOPS (Input/Output Operations Per Second) measures the speed at which storage can process data. Increased IOPS ensures the database handles higher transactional loads efficiently.

• Question 198:

  A company wants to utilize its private cloud for a new application. The private cloud resources can meet 75% of the application's resource requirements. Which of the following scaling techniques can the cloud administrator implement to accommodate 100% of the application's requirements?

  A. Horizontal
  B. Vertical
  C. Cloud bursting
  D. Autoscaling
  B. Vertical

  Explanation

• Question 199:

  A systems administrator needs to configure SSO authentication in a hybrid cloud environment.

  Which of the following is the BEST technique to use?

  A. Access controls
  B. Federation
  C. Multifactor authentication
  D. Certificate authentication
  B. Federation

  ---

  Explanation

  Federation is a type of authentication mechanism that allows users to access multiple systems or applications across different domains or organizations with a single login credential. Federation can help configure SSO authentication in a hybrid cloud environment, as it can enable seamless and secure access to cloud-based and on- premises resources using the same identity provider and authentication method. Federation can also improve user convenience, productivity, and security, as it can simplify the login process, reduce login errors, and enhance password management.

• Question 200:

  A SAN that holds VM files is running out of storage space.

  Which of the following will BEST increase the amount of effective storage on the SAN?

  A. Enable encryption
  B. Increase IOPS
  C. Convert the SAN from RAID 50 to RAID 60
  D. Configure deduplication
  D. Configure deduplication

  ---

  Explanation

  Deduplication is a type of data compression technique that eliminates redundant or duplicate data blocks or segments in a storage system or device. Configuring deduplication can help increase the amount of effective storage on a SAN that holds VM files and is running out of storage space, as it can reduce the storage space consumption and increase the storage space utilization by storing only unique data blocks or segments. Configuring deduplication can also improve performance and efficiency, as it can speed up data transfer and backup processes and save network bandwidth and power consumption.
