• Question 351:

  A company is doing a cloud-to-cloud migration to lower costs. A systems administrator has to plan the migration accordingly.

  Which of the following considerations is MOST important for a successful, future-proof, and low-cost migration?

  A. Tier pricing
  B. Licensing
  C. Estimated consumption
  D. Feature compatibility
  D. Feature compatibility

  ---

  Explanation

  Feature compatibility is an important consideration for a successful cloud-to-cloud migration, as different cloud providers may have different features, services, APIs, and standards. If the application relies on specific features that are not available or compatible with the target cloud provider, the migration may fail or incur additional costs and complexity. The administrator should assess and compare the features of both cloud providers and ensure they meet the application requirements.

• Question 352:

  A cloud administrator has received a physical disk that was analyzed by the incident response team. Which of the following documents should the cloud administrator update?

  A. Chain of custody
  B. Incident taxonomy
  C. Risk register
  D. Incident playbook
  A. Chain of custody

  ---

  Explanation

  Answer: A. Chain of custody

  A chain of custody is a document that records the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence. A chain of custody is important to ensure the integrity and admissibility of evidence in legal

  cases. A cloud administrator who receives a physical disk that was analyzed by the incident response team should update the chain of custody to document when, how, and by whom the disk was handled, and what actions were performed

  on it12. An incident taxonomy is a classification system that provides additional information about an incident, such as the nature, impact, intent, root cause, and data exposed. An incident taxonomy is useful for identifying trends and patterns, but it

  does not track the movement or manipulation of evidence3. A risk register is a document that identifies, records, and assesses potential risks in a project or an organization. A risk register helps to prioritize and mitigate risks, and to develop contingency plans. A risk register is not directly related to the

  analysis of a physical disk by the incident response team4. An incident playbook is a document that provides a series of prescriptive steps and guidance for responding and resolving incidents. An incident playbook helps to simplify and standardize the response process, and to reduce human error.

  An incident playbook does not record the details or outcomes of the response actions5.

• Question 354:

  A systems administrator is building a new virtualization cluster. The cluster consists of five virtual hosts, which each have flash and spinning disks. This storage is shared among all the virtual hosts, where a virtual machine running on one host may store data on another host.

  This is an example of:

  A. a storage area network
  B. a network file system
  C. hyperconverged storage
  D. thick-provisioned disks
  C. hyperconverged storage

  ---

  Explanation

  Hyperconverged storage is a type of storage architecture that combines compute, storage, and network resources into a single system or appliance. Hyperconverged storage uses software-defined storage (SDS) to pool and share the local storage of each node in the cluster, creating a distributed storage system that can be accessed by any node or virtual machine in the cluster. Hyperconverged storage can provide high performance, scalability, and efficiency for virtualized environments. The scenario of building a new virtualization cluster with five virtual hosts that share their flash and spinning disks among all the virtual hosts is an example of hyperconverged storage.

• Question 355:

  A company is currently running a website on site. However, because of a business requirement to reduce current RTO from 12 hours to one hour, and the RPO from one day to eight hours, the company is considering operating in a hybrid environment. The website uses mostly static files and a small relational database.

  Which of the following should the cloud architect implement to achieve the objective at the LOWEST cost possible?

  A. Implement a load-balanced environment in the cloud that is equivalent to the current on-premises setup and use DNS to shift the load from on premises to cloud.
  B. Implement backups to cloud storage and infrastructure as code to provision the environment automatically when the on-premises site is down. Restore the data from the backups.
  C. Implement a website replica in the cloud with auto-scaling using the smallest possible footprint. Use DNS to shift the load from on premises to the cloud.
  D. Implement a CDN that caches all requests with a higher TTL and deploy the laaS instances manually in case of disaster. Upload the backup on demand to the cloud to restore on the new instances.
  C. Implement a website replica in the cloud with auto-scaling using the smallest possible footprint. Use DNS to shift the load from on premises to the cloud.

  ---

  Explanation

  This is the best solution to achieve the objective of reducing current RTO (Recovery Time Objective) from 12 hours to one hour, and RPO (Recovery Point Objective) from one day to eight hours, at the lowest cost possible, for a website that uses mostly static files and a small relational database. RTO is a metric that measures how quickly a system or service can be restored after a disruption or disaster. RPO is a metric that measures how much data can be lost or how far back in time a recovery point can be without causing significant impact or damage. To reduce RTO and RPO, the administrator should implement a website replica in the cloud with auto-scaling using the smallest possible footprint. A website replica is a copy or backup of a website that can be used for recovery or failover purposes. Auto-scaling is a feature that allows cloud resources or systems to adjust their capacity and performance according to demand or workload. Using auto-scaling with the smallest possible footprint can minimize costs by using only the necessary resources and scaling up or down as needed. The administrator should also use DNS (Domain Name System) to shift the load from on premises to the cloud. DNS is a service that translates domain names into IP addresses and vice versa. Using DNS, the administrator can redirect traffic from the on-premises website to the cloud replica in case of a disruption or disaster, and vice versa when recovery is complete.

• Question 356:

  A business is looking at extending the platform for an internally developed application using microservices from various cloud vendors. The cloud architect is responsible for reviewing the proposed solution design, which covers critical requirements for the business to fulfill its requirements. Which of the following is the most likely requirement the cloud architect needs to fulfill?

  A. Software
  B. Budgetary
  C. Security
  D. Integration
  D. Integration

  ---

  Explanation

  Integration is the process of connecting and coordinating different components or systems to work together as a whole. In this scenario, the business is looking at extending the platform for an internally developed application using microservices from various cloud vendors. This means that the cloud architect needs to ensure that the microservices can communicate and interact with each other across different cloud platforms, as well as with the existing application. Integration is a critical requirement for the business to fulfill its requirements, as it affects the functionality, performance, and reliability of the application. Software, budgetary, and security are also important requirements, but they are not the most likely ones that the cloud architect needs to fulfill in this scenario. Software refers to the programs and applications that run on the cloud platforms. Budgetary refers to the costs and expenses associated with the cloud services and solutions. Security refers to the protection of the data and resources in the cloud environment from unauthorized access or attacks.

• Question 357:

  A production engineer is configuring a new application, which is running in containers, that requires access to a database. Which of the following methods will allow the application to authenticate to the database in the MOST secure way?

  A. Store the credentials in a variable on every worker node
  B. Store the credentials on a shared volume using whole-disk encryption
  C. Store the credentials in a configuration file using SHA-256 inside the container image
  D. Store the credentials using the orchestrator secret manager
  D. Store the credentials using the orchestrator secret manager

  ---

  Explanation

  The most secure way to store the credentials for a new application that is running in containers and requires access to a database is to use the orchestrator secret manager. The orchestrator secret manager is a feature that allows storing and managing sensitive data, such as passwords, tokens, or keys, for containers in an encrypted and centralized way. It also provides access control, auditing, and rotation features for the secrets. This method will protect the credentials from being exposed or compromised by unauthorized parties or malicious actors.

• Question 358:

  In an existing IaaS instance, it is required to deploy a single application that has different versions.

  Which of the following should be recommended to meet this requirement?

  A. Deploy using containers
  B. Install a Type 2 hypervisor
  C. Enable SR-IOV on the host
  D. Create snapshots
  A. Deploy using containers

  ---

  Explanation

  Containers are a type of deployment technology that packages an application and its dependencies into a lightweight and portable unit that can run on any platform or environment. Containers can help deploy a single application that has different versions in an existing IaaS instance, as they can isolate and run multiple versions of the same application without any conflicts or interference. Containers can also enable faster and easier deployment, scaling, and management of cloud-based applications.

• Question 359:

  A systems administrator is deploying a new storage array for backups. The array provides 1PB of raw disk space and uses 14TB nearline SAS drives. The solution must tolerate at least two failed drives in a single RAID set.

  Which of the following RAID levels satisfies this requirement?

  A. RAID 0
  B. RAID 1
  C. RAID 5
  D. RAID 6
  E. RAID 10
  D. RAID 6

  ---

  Explanation

  RAID 6 is a type of RAID level that uses block-level striping with two parity blocks distributed across all member disks. RAID 6 can provide redundancy and fault tolerance, as it can survive the failure of up to two disks without losing any data. RAID 6 can also support large data sets and high-capacity disks, as it can offer more usable space and better performance than other RAID levels with similar features, such as RAID 5 or RAID

  10. RAID 6 is the best RAID level for a systems administrator to use when deploying a new storage array for backups that provides 1PB of raw disk space and uses 14TB nearline SAS drives and must tolerate at least two failed drives in a single RAID set.

• Question 360:

  A systems administrator is planning to deploy a database cluster in a virtualization environment. The administrator needs to ensure the database nodes do not exist on the same physical host. Which of the following would best meet this requirement?

  A. Oversubscription
  B. Anti-affinity
  C. A firewall
  D. A separate cluster
  B. Anti-affinity

  ---

  Explanation

  Anti-affinity is the concept of ensuring that certain virtual machines or workloads do not run on the same physical host. This can improve the availability and performance of the system, as well as prevent a single point of failure. In this scenario, the systems administrator needs to ensure the database nodes do not exist on the same physical host, so anti-affinity would best meet this requirement. Oversubscription is the concept of allocating more resources to virtual machines than the physical host actually has, which can improve the utilization and efficiency of the system, but it does not guarantee the separation of the database nodes. A firewall is a device or software that controls the network traffic between different zones or segments, which can improve the security and isolation of the system, but it does not affect the placement of the database nodes. A separate cluster is a group of hosts that share common resources and policies, which can improve the scalability and manageability of the system, but it does not ensure the database nodes do not exist on the same physical host within the cluster.
