A major revamp of Cisco\u2019s network certification program started this week, so IT pros seeking to beef up their credentials \u2013 and those looking to renew certifications they\u2019ve already earned \u2013 face a different set of requirements.\nThe overhaul of the cert exams means changes to the body of knowledge that IT pros need to master in order to qualify. It also introduces Cisco DevNet certifications focused on programming that are meant to prepare candidates for employment in Cisco networking environments that rely more and more on software.\u00a0\nThe new line-up is in response to IT job postings that increasingly seek skills the former certifications didn\u2019t address, particularly in emerging areas such as IoT, SD-WAN, multi-cloud, and machine learning.\n\nMore on Cisco certs:\n\n10 things to know about the Cisco certification overhaul\nAre new Cisco certs too much?\nCisco launches a developer-community cert program\n\n\nIn the UK, the CCNA and CCNP are two of the most desired certifications, and there are changes to both.\nThe new CCIE certification is issued in five areas of concentration \u2013 enterprise, security, service provider, collaboration, or data center \u2013 and requires candidates to pass a written exam and a lab exam in the core topic. Similarly, the CCNA is offered in the same concentration areas and requires passing the same core written exam as the CCIE but has a written concentration exam rather than the lab exam.\nThe most in-demand certifications are CCNA and CCNP in routing and switching, CCNA in security, Cisco Certified Entry Networking Technician (CCENT), and Cisco Certified Design Associate (CCDA), according to Global Knowledge.\nThe certifications are popular in part because those who have them may stand to earn more. According to IT Jobs Watch, the median annual salary for jobs in the UK (excluding London) that require Cisco certifications is \u00a347,500, compared to \u00a346,500 for all other academic and professional certifications. The same numbers for jobs in London are \u00a370,000 for Cisco certifications and \u00a360,000 for other academic and professional certs.\nDrilling down, IT Jobs Watch says jobs requiring a CCNP pay a median salary of \u00a360,000 in London and \u00a350,000 in the rest of the UK. The average UK salary for a CCIE ranges from \u00a390,000 for a CCIE in collaboration down to \u00a363,750 for one in routing and switching. However, the certs aren\u2019t a guarantee of higher pay. The median UK salary for a job requiring a CCNA is \u00a345,000, slightly less than the average \u00a346,500 for other academic and professional certifications.\nWhere to take prep classes\nIn the UK, courses to prepare candidates for the Cisco certification exams are available in classrooms and online. Here are a few of each.\nIn London, certificate seekers can take Cisco-certification prep courses at London Metropolitan University. These include CCNA routing and switching, CCNP routing and switching, CCNA security and CCNA cybersecurity operations.\nThe Open University offers Cisco classes to prep for CCNA and CCNP exams.\nFocus on Training offers a range of Cisco prep courses in London, Birmingham, Manchester, Leeds and other UK cities.\nThe Knowledge Academy holds Cisco-cert prep classes in dozens of locations throughout the UK.\nSites offering online classes include reed.co.uk, distancelearningcentre, coursesonline, My Training Academy, among others. Cisco itself offers training for the certificate exams as well.
