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 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.

What type of replication notifies an application that data has been written before replica servers verify data has been committed to disk? Master-slave Asynchronous Synchronous Peer-to-peer

Asynchronous

Which term is best associated with data backups? Performance Integrity Availability Confidentiality

Availability

You need to ensure that critical on-premises virtual machines are immediately available in the event of a regional disaster. What should you configure? Cloud failover Failover cluster Hourly backups Virtual machine clones

Cloud failover

Which statement regarding the RPO is correct? The RPO is the maximum tolerable downtime of a business process. A single RPO applies to all data. The RPO is the minimum tolerable downtime of a business process. Different types of data could require different RPOs.

Different types of data could require different RPOs.

Which type of backup does not modify the archive bit? Snapshot Incremental Differential Full

Differential

You need to ensure that server backups have a minimal impact on user productivity. When should you schedule backups to occur? During maintenance windows 12 A.M.-5 A.M. During failback windows 6 P.M.-12 A.M.

During maintenance windows

Incremental cloud database backups occur three times daily. What is the RPO? One hour Three hours Five days Eight hours

Eight hours

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.

A virtual machine file server's virtual hard disks are corrupt and cannot be repaired. Which type of tape backup will take the least amount of time to restore? Snapshot Incremental Differential Full

Full

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

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

Incremental

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

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.

While creating a DRP, you are concerned with how long the restoration of data files will take. You conclude the restoration cannot exceed three hours. What is another way of stating this? RPO = 3 hours Backup = 3 hours RTO = 3 hours Restore = 3 hours

RTO = 3 hours

Which recovery factor has the largest influence on the selection of the type of alternate site? RPO RTO SLA DRP

RTO

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.

You are the IT director for a law enforcement agency. The agency IT system must remain running at all times. An alternate location to house mission-critical servers, data, and personnel has been acquired. What else is needed for this hot site? Load balancing Replication Failover clustering Virtualization

Replication

Which type of document states how service providers will compensate service consumers if specific conditions are not met? BCP DRP BIA SLA

SLA

Which monitoring technique uses hard disk metrics to predict hard disk imminent failure? SMART MTTR MTBF KP

SMART

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.

How is the DRP different from the BCP? The DRP is specific to a system. The BCP is specific to a system. The DRP is related to business continuity. The BCP is related business continuity.

The DRP is specific to a system.

The archive bit for files modified since the last backup will be set to which value? b m 0 1

1

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 type of alternative business site is the cheapest? Warm Hot Cold Lukewarm

Cold

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.

Which communication method is used for inter-node cluster communication? Shared storage LUN iSCSI Heartbeat

Heartbeat
