Best System Administrator Certifications

Network architect

When it comes to managing computer systems, whether in an office environment, on a campus or in an enterprise data center, there's a long list of tools and technologies SysAdmins need to master. Also, numerous certifications can help validate knowledge and skills in those areas.

In addition to server and client configuration and maintenance, many system administrators must understand access controls, network services and resource requirements for applications. They often find themselves working with directory and name services as well as network addressing, database services, web and desktop applications, email and more.

Making sense of all these different system administrator roles and accompanying certifications is no easy task. After examining various credentials, we came up with a list of our five favorite system administrator certifications for 2018.

The following chart shows the results of an informal job search we conducted that gives you an idea of the relative frequency with which our top five certifications appear in actual job postings. While all the certifications are popular, the CompTIA Server+ stands out as the clear favorite.

MCSE: Cloud Platform and Infrastructure (Microsoft)






Oracle Linux System Administrator (Oracle)






RHCE (Red Hat)






Server+ (CompTIA)






VCP6-DCV (VMware)*






* Despite higher results for a few certifications we considered – namely, the IBM Certified System Administrator (409), ServiceNow Certified System Administrator (341) and LPI's LPIC (193) – searching for VCP Data Center resulted in more than 900 hits. Those job descriptions revealed employers prefer or require a VCP data center certification, but don't indicate the specific version. The latest VMware certification  ̶  VCP6.5-DCV  ̶  is too new to generate significant hits in job board results.

Although employers tend to pay SysAdmins at a lower rate than some of their IT peers, such as network engineers and data architects, a career in system administration is still worth pursuing. SimplyHired reports $73,697 as the national average salary for SysAdmins, in a range from $47,540 to $114,246. Indeed.com pegs the average at $67,444, and Glassdoor's average is $67,617.


The Microsoft Certified Solutions Expert (MCSE) certification has long ruled the hearts and minds of those who work on Microsoft-based systems, servers and clouds. MCSE certifications focus on the latest technologies for business applications, cloud infrastructures, data management and analytics, mobility and productivity.

But when it comes to system administration certifications in general, the brightest lights are those that address Windows Server at the enterprise and server administrator levels. While these credentials don't all specifically use "system administrator" in their descriptions, they all fall well inside the roles and responsibilities of system administration jobs. They're also in high demand in job postings and classified job advertisements.

The MCSE: Cloud Platform and Infrastructure targets IT professionals seeking to promote careers such as information security analysts or computer support specialists. Those obtaining the certification will find that the MCSE: Cloud Platform and Infrastructure credential is designed to validate the skills necessary to effectively run a data center, including networking, storage, systems management, virtualization and identity management.

Note: The Microsoft Certified Solutions Associate (MCSA) is Microsoft's prevailing mid-range IT certification. It covers most administrative job roles, including system administration at both the desktop and server levels, as well as more specialized job roles that include SQL Server and Office 365. MCSA: Cloud Platform is a gateway certification that feeds into the MCSE certifications.

System administration candidates might also want to take a close look at the MCSE: Productivity credential, which garners nearly as many hits on job boards as the MCSE: Cloud Platform and Infrastructure cert. The MCSE: Productivity focuses on Microsoft Exchange, SharePoint or Skype For Business. Because communications systems and services of all kinds are so important to business, these are good areas for aspiring and practicing system administrators to specialize in.

The Microsoft Certification Program underwent extensive changes in September 2016. Once you earn one of the latest MCSE credentials, you do not have to recertify within three years as was the case in the past. However, by passing an elective exam each calendar year, you add an entry to your transcript that indicates your commitment to staying current on technologies and expanding your skillset.

In the realm of Linux system administrator certifications, Red Hat certifications really stand out. Red Hat's more senior-level certifications are especially popular among IT professionals as well as the employers who hire them. Those holding the Red Hat Certified Engineer (RHCE) credential qualify for job roles such as senior Linux administrator, senior UNIX administrator, senior systems engineer, infrastructure systems engineer, IT analyst and the like.

The RHCE is regarded as a high-level credential that's not easy to obtain. Candidates must first obtain the Red Hat Certified System Administrator (RHCSA) credential and then pass a three and a half hour, hands-on, performance-based exam that's both intense and demanding. Those who earn the RHCE can go on to earn one of the Red Hat Certified Architect (RHCA) credentials, including:

  • RHCA: Cloud
  • RHCA: Datacenter
  • RHCA: Application platform
  • RHCA: Application development
  • RHCA: DevOps

The current RHCE exam is based on Red Hat Enterprise Linux (RHEL) 7. RHCE certification is valid for three years from the date the certification was achieved.

The VMware family of certifications are must-have credentials for IT professionals interested in the field of virtualization. Offering a comprehensive certification program that encompasses all skills levels, VMware credentials are recognized globally as best in class.

VMware offers candidates an entry-level cert in the form of the VMware Certified Associate 6 - Data Center Virtualization (VCA6-DCV), followed by the next tier on the certification ladder, the VMware Certified Professional 6 - Data Center Virtualization (VCP6-DCV). The VCP6-DCV prepares credential holders for more advanced certifications, including the VMware Certified Advanced Professional (VCAP6-DCV) and the pinnacle cert, VMware Certified Design Expert (VCDX-DCV).

Beyond the five system administrator certifications featured in this article, there are many other certification programs that can help to further the careers and professional development of IT professionals who work in system administration.

It makes sense to investigate the plethora of vendor-specific programs available for those who work with systems from companies such as Brocade, Dell EMC, HPE, IBM, NetApp, Symantec and so forth. Many of them play into key system specialty areas, such as storage, security or virtualization, while others offer a broad range of platforms for these and other technology areas. Here are some examples:

  • HP ASE - HP-UX 11i v3 Administrator V1, for technical professionals with advanced skills in installing, configuring and maintain HP-UX servers in mission-critical environments
  • IBM Certified System Administrator (and Advanced Administrator), for Connections, Sametime, Lotus Notes, Informix, IBM i and more
  • NetApp Certified Data Administrator (NCDA), geared toward professionals who manage NetApp data storage controllers running the ONTAP operating system
  • ServiceNow Certified System Administrator, aimed at professionals who are adept at configuring, implementing and managing ServiceNow systems

Likewise, vendor-neutral certification programs also offer a variety of interesting and potentially valuable credentials. For example, the LPI LPIC certifications, which had been in our top five list for several years, are well known and widely recognized in IT shops and operations that depend on Linux servers to handle their workloads.

It's best to think of our top five certifications as a good place to start, while also realizing that there are many other options to consider as well.
