Disaster recovery testing is important in determining the effectiveness of a disaster recovery plan. In this type of testing, a system is created that closely resembles the production network. The disaster recovery team is able to restore systems and data to simulate the disaster recovery process without interfering with the production network.
Parallel test
:
The Mean Time Between Failures is used to measure the reliability of a component or system by
Taking the total operational time and dividing it by the total number of failures
:
The Mean Time to Repair (MTTR) is defined as the average time it takes to repair a system or component after a failure occurs.
Which strategy can be used to monitor the state of a system or component and avoid the downtime caused by a system failure thus significantly reducing the overall MTTR?
Proactive maintenance
:
Organizations that suffer a failure of a system or function can only tolerate that loss for so long before it significantly affects business operations. This maximum time that can be tolerated is called the ______.
Recovery time objective
:
The Recovery Point Objective (RPO) is important in determining an organization’s tolerance for data loss.
What is an effective strategy for reducing the organization’s RPO?
Increase the frequency of backups
:
In this high-availability approach, a node or server, is fully configured but not currently sharing any of the operational load. In the event of a system failure, the node or server enters operation preventing downtime or any degradation in service.
Active-passive
:
This network monitoring solution provides information on the types of data moving in a network, which can be monitored over time to detect trends and indicate possible bottlenecks. This information can be used to prevent network slowdowns or outages in the network fabric.
Traffic Analysis
:
You are a network administrator for your organization and are tasked with implementing network monitoring. You have decided to use the Simple Network Management Protocol SNMP) to aid with the collection of data in your network. You require that the information be stored in a Management Information Base (MIB) on each device and that it be protected with a password. You also want the collection of the data from the device to use encryption.
Which SNMP version fulfills the required parameters?
V3
:
In a disaster recovery plan, an alternate location can provide a site where the organization’s operations can continue. This type of site has a completely operational network and a live copy of the organization’s data. This site can be activated in moments but is the most costly alternative for a disaster recovery site.
