Opening a TAC Case

The online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and P4 cases. (Your network is minimally impaired or you require product information). After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using these recommendations, your case will be assigned to a Cisco TAC engineer.

For P1 or P2 cases (your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

To open a case by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

EMEA: +32 2 704 55 55

USA: 1 800 553-2447

OL-3995-01 specifications

Cisco Systems OL-3995-01 refers to the Cisco Certified Network Associate (CCNA) certification exam, which serves as a fundamental stepping stone for IT professionals and network engineers looking to establish a robust foundation in networking technologies. The CCNA certification focuses on a wide range of essential skills and concepts that are vital in the networking domain.

One of the main features of the Cisco OL-3995-01 exam is its emphasis on network fundamentals. This includes an understanding of network types, models, and protocols. Candidates learn about the OSI model, IP addressing, and subnetting, which are critical for managing and troubleshooting networks. Additionally, the exam covers LAN and WAN technologies, providing insights into how data is transmitted over different types of networks.

Another key aspect of the OL-3995-01 exam is security fundamentals. With the increasing importance of cybersecurity, this certification prepares candidates to implement basic security measures and understand the principles of network security. Topics include securing network devices, managing access control lists, and understanding common security threats, which are essential for protecting organizational data and infrastructure.

The exam also explores automation and programmability, reflecting the evolving nature of networking in modern IT environments. Cisco emphasizes the significance of software-defined networking (SDN) and network automation tools that facilitate network management and efficiency. This prepares candidates for environments where manual configurations are being replaced by automated processes.

Moreover, the OL-3995-01 exam includes practical knowledge about IP services such as DHCP, NAT, and DNS, which are crucial for any network operation. Students learn how these services support network functionality and enhance user experience.

In terms of characteristics, the Cisco CCNA certification is globally recognized, making it a valuable credential in the IT job market. Cisco's reputation as a leader in networking solutions adds credibility to the certification, signaling to employers that the certified individual possesses a solid understanding of networking basics.
