Cloud Infrastructure Chp 12
An organization recently had a disaster and the data center failed over to the backup site. The original data center has been restored and the administrator needs to migrate the organization back to the primary data center. What process is the administrator performing? Failover Failback DRP RTO
. Failback is the process of switching back to the primary site after the environment has been shifted to the backup site.
Which of the following is a documented set of procedures that defines how an organization recovers and protects its IT infrastructure in the event of a disaster? MTBF MTTR RPO DRP
A DRP (disaster recovery plan) describes how an organization is going to deal with recovery in the event of a disaster.
Which of the following would be considered a cold site? A site with no heating system A site that has a replication enabled A site that is fully functional and staffed A site that provides only network connectivity and a physical location
A cold site does not include any backup copies of data from the organization's original data center. When an organization implements a cold site, it does not have readily available hardware at the site; the site only includes the physical space and network connectivity for recovery operations, and it is the organization's responsibility to provide the hardware.
Which of the following backups could be restored without any additional backups? Incremental Differential Full Image
A full backup backs up the entire system, including everything on the hard drive. It does not require any additional backups to perform a restore.
You are designing a disaster recovery plan that includes a multi-site configuration. The backup site must include all necessary hardware and current backups of the original site. Which type of site do you need to design? Cold site Warm site Hot site Virtual site
A hot site is a duplicate of the original site of the organization and has readily available hardware and a near-complete backup of the organization's data. A hot site can contain a real-time synchronization between the original site and the backup site and can be used to completely mirror the organization's original data center.
Which of the following backup processes needs the last backup and all additional backups since that backup to perform a restore? Incremental Differential Full Image
An incremental backup backs up the files that have changed since the last full or incremental backup and requires all incremental backups to perform a restore.
Which of the following processes allows a system to automatically switch to a redundant system in the event of a disaster at the primary site? Failback DRP Failover Redundancy
Failover is the process of switching to a redundant system upon failure of the primary system.
Which of the following terms can be used to describe a system that is location independent and provides failover? Clustering Load balancing Geo-clustering Failover
Geo-clustering uses multiple redundant systems that are located in different geographical locations to provide failover and yet appear as a single highly available system.
You have been tasked with distributing incoming HTTP requests to multiple servers in a server farm. Which of the following is the easiest way to achieve that goal? Mirror site Fault tolerance Redundancy Load balancing
Load balancing distributes workloads across multiple computers to optimize resources and throughput and to prevent a single device from being overwhelmed.
Which term is used to describe the target amount of time that a system can be down after a failure or a disaster occurs? RPO RTO BCP MTBF
RTO (recovery time objective) is the target amount of time a system can be down after a failure or disaster.
What is the easiest method for an administrator to capture the state of a virtual machine at a specific point in time? Backup Snapshot Image Clone
Snapshots can be used capture the state of a virtual machine at a specific point in time. They can contain a copy of current disk state as well as memory state.
When replicating data in a multisite configuration from the primary site to a backup site, which form of synchronization requires the system to wait before proceeding with the next data write? Asynchronous replication Synchronous replication Failover Mirror site
Synchronous replication writes data to the local store and then immediately replicates it to the replica set or sets. The application is not informed that the data has been written until all replica sets have acknowledged receipt and storage of the data.
