CompTIA Cloud+ Domain 5 Troubleshooting

CompTIA Cloud+ Domain 5 Troubleshooting

Domains of CompTIA Cloud+

CompTIA Cloud+ certification covers five domains.
Domain 1: Cloud Architecture and Design 13%
Domain 2: Security 20%
Domain 3: Deployment 23%
Domain 4: Operations and Support 22%
Domain 5: Troubleshooting 22%
We will be discussing the fifth domain, ‘Troubleshooting.
Troubleshooting is a technique for solving problems that is often used to fix damaged goods or processes on a computer or machine. It is the Root Cause Analysis (RCA) process in Information Technology that assists you in finding a bug in a program. It is a methodical, logical search for the root cause of a problem to fix it and restore functionality to a product. Troubleshooting is necessary to diagnose the problem. This domain, along with Operations and Support, has the second-highest weightage of 22%. It is therefore important. This domain will give an overview of topics such as troubleshooting cloud issues, security issues and deployment issues, connectivity issues and performance issues, as well as automation and orchestration issues.
1. Troubleshooting methods to resolve cloud-related problems. In this sub-domain, you will learn about troubleshooting methodologies to resolve cloud issues in a given situation. Before making changes to corporate policies, procedures and impacts, we need to be aware of how to do this.
A. Identify the problem by asking the user questions. Identify user changes to the computer. Perform backups before making any changes. Ask about infrastructure or environmental changes
B. B.
C. Test the theory to find the cause. Once the theory has been confirmed, determine the next steps for solving the problem. If the theory isn’t confirmed, you can re-establish it or escalate.
D. Create a plan of actions to solve the problem and then implement it.
E. Verify the system functionality and, where applicable, take preventive measures.
F. Document the findings, actions and results throughout the process.

2. Troubleshooting security problemsIn this sub-domain we will learn how to troubleshoot security problems in a given situation. We will learn about privilege, authentication and authorization, security groups and keys, misconfigured policies and certificates, data security issues, exposed endspoints, misconfigured security appliances, failed security appliances, unsupported protocols and external/internal attack. We will learn about privileges such as missing, incomplete, escalation and keys. Security groups will guide us through directory security groups and network security groups. Topic keys and certificates deal with expired, revoked trust, compromised, and misconfigured certificates. Data security issues will cover data breaches, unencrypted data and misclassification. We also discuss the lack of encryption in protocols and insecure cryptohers. We will examine IPS, IDS and NAC for misconfigured or failing security appliances.
3. Troubleshooting deployment issues This sub-domain teaches you how to troubleshoot deployment problems in a given situation. We will be learning about connectivity issues, performance degradation and configurations, applications within containers, misconfigured templates as well as missing or incorrect tags, insufficient capacities, licensing issues, and vendor-related problems. We will be discussing connectivity issues with Cloud Service Providers, (CSP), and Internet Service Providers, (ISP). Latency comes under performance degradation. We will be able to see scripts in the topic configurations. We will also learn about scaling configurations, compute storage, bandwidth issues and oversubscription when there is insufficient capacity. We will learn about vendor-related issues such as migrations of vendors, platforms, integration of vendors, and pl
