It is critical for organizations to perform some form of Signature Verification when getting Cisco certifications such as CCNA, CCIE, CCNP, CCSA and so on. These certifications are important to give an organization a competitive edge over its competitors. However, the most important thing for companies to remember is that these certifications should be verified by a third party before the organizations are granted certification.
Some providers offer their clients a solution to perform their own signature verification. This is done by checking for duplicate lines in the WLAN database. The process of checking for duplicates is not foolproof because someone could make changes to the lines in an employee handbook. Therefore, companies should be sure to have their signature verified before Cisco certification can be issued.
The most common way for a Cisco certification to be refused due to signature verification failure is due to an incorrect user ID. When a client applies for a Cisco certification, the name that they use is used to determine if their certification is approved or declined. If there is an error in the user ID, then the application will fail. In addition, if a person uses a middle initial that is different than the one that is entered during the sign up process, then the application will fail also. A good way to avoid this problem is to use only numerical user ID during the sign up process.
Another reason why Cisco certification may be refused for signature verification is when a company incorrectly inputs any information into the WLAN database. When a Cisco device is linked to more than one WLAN, it is easy for the wrong information to get into the database. When a Cisco device appears on more than one WLAN, it is likely for signature verification to fail. In many cases, the failed application will return an error code. However, in some cases, the returned code will also contain the word unsupported, indicating that the information is not supported by the WLAN card.
Companies can avoid having signature verification failed in their Cisco exams by following certain tips. First, the WLAN configuration should be correct. If a WLAN requires additional authentication, then it should be configured in the right way. The WLAN configuration of a VPN and a private Local Area Network should be allowed by a VPN to avoid issues with signature verification failing. It is also important to ensure that a private Local Area Network has been setup between all workstations on a WLAN.
The certificate stored on a VPN server should always be updated. The most common reasons why Cisco certificate validation failed due to updates are incomplete or incorrect policy definitions. A CCNA certification should be updated whenever a new release of the CCNA tools or other programs is available. Any changes to CCNA security policies should be made using the same procedure as when you make any other changes. It is important to update a Cisco security policy at least once every 12 months. Any older policy will not be effective and may have a negative effect on Cisco certification.
If a third-party has issued a security certificate, such as a CCNA or other type of CCNA, and your IT administrator for your network is not aware of this, he or she should verify the authenticity of the certificate. Forcing a vendor-driven signature can cause serious security problems. The IT administrator should verify that the vendor-driven signature matches the current CCNA definitions. Verification to verify validity of a signature can be done manually or by obtaining a signed copy of the request. Verification of the certificate by an independent party will give you assurance that the CCNA Validation failed because of a flaw that was identified and resolved.
