A cloud administrator who is troubleshooting DNS issues discovers zone transfers are not occurring between the primary and secondary name servers due to an error in the serial numbers. Which of the following records should the administrator query for the serial number?
SOA stands for Start of Authority, and it is a type of DNS record that contains information about a DNS zone, such as the name of the primary name server, the email address of the zone administrator, the serial number of the zone, and other parameters. The serial number is used to indicate when a zone has been updated, and it is incremented by the primary name server whenever a change is made to the zone dat
a. The secondary name servers use the serial number to determine if they need to request a zone transfer from the primary name server to synchronize their data.
A cloud administrator is reviewing the current private cloud and public laaS 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 systems administrator notices the host filesystem is running out of storage space. Which of the following will best reduce the storage space on the system?
Deduplication is a technique that reduces the storage space by eliminating duplicate data blocks and replacing them with pointers to the original dat
a. Deduplication can help free up the host filesystem by removing redundant data and increasing the storage efficiency. Deduplication can be performed at the source or the target, and it can be applied at the file or block level. Reference: [CompTIA Cloud+ CV0-003 Certification Study Guide], Chapter 4, Objective 4.3: Given a scenario, troubleshoot common storage issues.
A cloud engineer recently used a deployment script template to implement changes on a cloud-hosted web application. The web application communicates with a managed database on the back end. The engineer later notices the web application is no longer receiving data from the managed database. Which of the following is the most likely cause of the issue?
Based on the shared responsibility model, which of the following solutions passes the responsibility of patching the OS to the customer?
IaaS stands for Infrastructure as a Service, and it is a cloud service model that provides customers with access to virtualized computing resources, such as servers, storage, and networks. In the IaaS model, the customer is responsible for patching the operating system (OS) of the virtual machines, as well as installing and managing the applications and dat
