CompTIA Lesson13: Implementing High Availability and Disaster Recovery in the Cloud

An organization has concerns about single points of failure for their VMs. What can the cloud administrator use to ensure all the VMs do not fail at the same time?

Anti-affinity

An organization has recently recovered from a data breach and is working to identify what created the circumstances that allowed the breach to occur. What is the best way for the organization to understand the root cause?

Ask a series of "Why" questions.

In which instance would an organization NOT employ the disaster recovery playbook?

Cloud administrator quits

Which of the following represents a single point of failure? (Select all that apply.)

Cloud direct connection. Load balancer.

A small marketing firm is preparing a business continuity plan and needs to select the right kind of disaster recovery site. The firm's business relies on created and approved marketing campaign files to run daily campaigns and internet connectivity to run the business on the front end. The firm also uses customer relationship management software, as well as the website, for sales. The firm is in a tornado-prone area, but the firm's customers reside all across the country. One day of being unable to post a customer's campaign can cause the firm to lose business. What is the best disaster recovery solution for the marketing firm?

Cloud site

What kind of documentation should an organization have on hand to respond to an incident in the cloud? (Select all that apply.)

DR playbook. Call tree. Network flow diagram.

An administrator has configured a cluster of web servers to ensure that if one server becomes unavailable, the other will continue to serve traffic. What does the cluster represent?

High availability

A hybrid cloud environment hosts web services on both on-premises and the cloud. A similar network is set up in an isolated environment for testing disaster recovery scenarios. If IT management wants to test their disaster recovery procedures with the participation of a limited amount of real user accounts, what type of test would be most appropriate to carry out?

Live cutover

A cloud administrator is configuring a load balancer to manage traffic to an organization's web servers that house a catalog of products for customers to buy online. What load balancer scheduling type should the cloud administrator configure to ensure that all customers can place orders at all times?

Most recently used.

An organization is testing the cloud disaster recovery plan. The goal is to implement the recovery without disrupting production. What kind of test is the organization running?

Parallel recovery

A server administrator was recently assigned the role of disaster recovery planning. They have developed a plan but are not quite ready for full scale testing. They do, however, want to include other people in the process. Which of the following will help the administrator at this point? (Select all that apply.)

Parallel recovery. Walk through. Table-top.

An organization recently experienced a data breach in the cloud network while a new cloud administrator was on call. The organization had all the necessary documentation to respond to the incident, but the response time was extremely slow compared to average incident response times. What can the organization do to decrease incident response times in the future?

Provide training.

An organization has a cloud deployment in an availability zone with redundant server hardware, redundant power supplies, and redundant network connectivity. What is the next step that represents the best solution for the organization to mitigate a single point of failure?

Replicate the cloud deployment to another zone.

An organization's cloud service provider (CSP) recently experienced an outage, which caused the organization's cloud instances to be down for 30 minutes. Where can the organization look to see if this is longer than the CSP's guaranteed percent availability?

SLA

A hybrid cloud solution with virtual hosts on-premises and in the cloud needs to avoid a single point of failure across both platforms. How can a cloud administrator force distribution of regular virtual machine (VM) instances across both platforms?

Set up anti-affinity rules.

An organization has learned that it may be competing with other organizations for access to the cloud service provider's (CSPs) resources. Which of the following CSP resources might the organization's be competing for? (Select all that apply.)

Storage. CPU and Memory. Bandwidth.

A database administrator works for a critical financial institution which requires the client machines to be informed after multiple servers have a copy of the transaction. What type of replication should the administrator set up?

Synchronous

About 70% of the company's customers are based on the east coast of the United States, while the company's headquarters is on the west coast. The company has resources in both a west and east coast region. What reasons may have influenced the company's decision to set up two regional cloud locations? (Select all that apply.)

To follow a disaster recovery playbook. To replicate virtual machines (VMs).

An organization had to evacuate their primary location due to approaching wildfires. As outlined in the business continuity plan, the organization moved all business operations to another location that they had previously set up with most of the equipment they needed. The organization acquired the rest of the needed equipment, restored data backups to the new location, and resumed operations within a day. What kind of disaster recovery site did the organization use?

Warm site

A solutions architect has performed a risk analysis for disaster recovery and has determined that the likelihood of needing to recover is very low. They also determined that needing some time to bring another center up is acceptable, but not too much time. Which of the following backup solutions would meet the company's needs? (Select all that apply.)

Warm site. Cloud site.

An organization is responding to a data breach in the cloud network. The organization has completely restored normal operations to the production environment and has isolated the breach on a specific segment of the network to further investigate and collect evidence. What negative action will eliminate the organization's chances of taking legal action against the threat actors?

Fail to track the chain of custody.
