Domains of the CompTIA Cloud+
www.infosectrain.com | [email protected]
CompTIA Cloud+ certification comprises a total of 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 discuss the fourth domain that is ‘Operations and 
Support’.
Operations and Support
The Operations and Support phase is abbreviated as the O&S phase that 
focuses on carrying out the product support strategy, meeting material 
readiness and operational performance criteria, and supporting the system in 
the most cost-effective way possible throughout its life cycle. The Operations 
and Support discipline’s main objective is to run and support your product in a 
live environment. This domain comprises the second-highest amount of 
weightage that is 22%, so it is an important domain. This domain will provide 
an overview of topics like operation status, efficient operation, optimizing 
cloud environments, automation and orchestration techniques, backup and 
restore operations, and disaster recovery.

1. Configure logging, monitoring, and alerting to maintain 
operational status
In this sub-domain, we learn to configure logging, monitoring, and alerting to 
maintain operational status in a given scenario. This domain will equip us 
with an in-depth understanding of logging, monitoring, and alerting. In 
logging, we will learn about collectors and types. Collectors explain the 
Simple Network Management Protocol (SNMP), and Syslog whereas the types 
define access/authentication, system, and application. We will also learn 
many different things like analysis, severity categorization, audits, 
automation, and trending. Monitoring provides an in-depth understanding of 
baselines, thresholds, tagging, log scrubbing, resource utilization, verification 
of continuous monitoring activities, service management tool integration, 
performance monitoring that incorporates application, and infrastructure 
components, and availability that incorporates SLA-defined uptime 
requirements. Alerting will take you through common messaging methods, 
appropriate responses, policies for categorizing and communicating alerts, 
and enable/disable alerts that explain maintenance mode.

2. Maintain efficient operation of a cloud environment
In this sub-domain, we learn to maintain the efficient operation of a cloud 
environment in a given scenario. We will get an understanding of the topics 
like confirm completion of backups, life-cycle management, change 
management, asset management, patching, impacts of process 
improvements on systems, upgrade methods, dashboard, and reporting. In 
the studies of life cycle management, we will learn about roadmaps, 
old/current/new versions, upgrading and migrating systems, and 
deprecations or end of life. We will learn about Configuration Management 
Database (CMDB) under asset management while in patching, we will learn 
all about features or enhancements, fixes for broken or critical infrastructure 
or applications, the scope of cloud elements to be patched, hypervisors, VMs, 
virtual appliances, networking components, applications, storage 
components, firmware, software, OS, policies, n-1, and rollbacks. In upgrade 
methods, we learn about rolling upgrades, blue-green, canary, active-
passive, and development/QA/production/DR. In dashboard and reporting, we 
will learn about tagging, costs, chargebacks, show backs, elasticity usage, 
connectivity, latency, capacity, incidents, health, overall utilization, and 
availability.

3. Optimize cloud environments
In this sub-domain, we learn to optimize cloud environments in a given 
scenario. This sub-domain will equip you with the knowledge of right-
sizing, compute, storage, network, placement, device drivers, and 
firmware. In right-sizing, we will learn about auto-scaling, horizontal 
scaling, vertical scaling, and cloud bursting, while in compute, we will 
learn about CPUs, GPUs, memory, and containers. We will learn about 
tiers, adaptive optimization, IOPS, capacity, deduplication, and 
compression in storage. We will learn about bandwidth, Network 
Interface Controllers (NICs), latency, SDN, edge computing, and CDN in 
the network. Placement will give us an idea of geographical, cluster 
placement, redundancy, and colocation. In device drivers and 
firmware, we will learn about the generic, vendor, and open source.

4. Apply proper automation and orchestration 
techniques
In this sub-domain, we learn to apply proper automation and 
orchestration techniques in a given scenario. We will gain 
knowledge of infrastructure as code, Continuous 
Integration/Continuous Deployment (CI/CD), version control, 
configuration management, containers, automation activities, 
secure scripting, and orchestration sequencing. In infrastructure 
as code, we will understand infrastructure components and their 
integration while the configuration management will provide 
knowledge of the playbook. The automation activities equip you 
with the idea of routine operations, updates, scaling, shutdowns, 
restarts, and create internal APIs. The secure scripting will take 
you through no hardcoded passwords, use of individual service 
accounts, password vaults, and key-based authentication.

5. Perform appropriate backup and restore 
operations
In this sub-domain, we learn to perform appropriate backup and 
restore operations in a given scenario. It will provide you in-depth 
knowledge of backups like backup types, backup objects, backup 
targets, backup and restore policies, and restoration methods. 
The topic backup types incorporate incremental, differential, full, 
synthetic full, and snapshot. In backup objects, we will learn 
about application-level backup, filesystem backup, database 
dumps, and configuration files. The topic backup targets will be 
brief about tape, disk, and object. Backup and restore policies will 
provide the knowledge of retention, schedules, location, SLAs, 
Recovery Time Objective (RTO), Recovery Point Objective (RPO), 
Mean Time To Recovery (MTTR), and 3-2-1 rule that is three 
copies of data, two different media, and one copy off-site. In 
restoration methods, we learn things like in place, alternate 
location, restore files, and snapshot.

6. Perform disaster recovery tasks
In this sub-domain, we learn to perform disaster recovery tasks in a given 
scenario. We learn all about failovers, failback, restore backups, replication, 
network configurations, on-premises and cloud sites, requirements, 
documentation, and geographical data center requirements. The topic on-
premises and cloud sites provide knowledge of hot, warm, and cold sites. 
The topic requirements will teach you all about RPO, RTO, SLA, and 
corporate guidelines. In the documentation, we will learn about the DR kit, 
playbook, and network diagram.
