The 642-874 Designing Cisco Network Service Architectures (ARCH) exam assesses the knowledge of the candidate on the latest network designs trends and developments including congregated network solutions, network infrastructure and services. The success in this exam establishes the capability of a candidate to execute theoretical, transitional and comprehensive design of network architecture. The candidates can efficiently support a network infrastructure with effective availability, accessibility and performance by emphasizing on the requirements of network solutions with intellectual network services. They can also design a converged enterprise network with their extensive knowledge on advanced technologies like Virtual Private Network (VPN) in designing network infrastructure.

Exam Description:

Why is this exam required?

The objective of the 642-874 ARCH exam is to test the knowledge and skills of a professional in relation to the concept of Cisco network Architectures, its use in designing enterprise network infrastructure, and creation of theoretical, transitional and comprehensive design for enterprise campus network, enterprise edge and remote infrastructure, VPN, data center and network service. Candidates succeeding in this exam can take up various job roles including:

  • Senior network design engineers
  • Principal systems engineers
  • Senior analysts

Associated Certifications

The associated certifications of the 642-874 ARCH exam is the Cisco Certified Design Professional (CCDP) certification. A CCDP certified professional can efficiently design and develop complex IP multicast network architectures, data center, sophisticated routing and addressing and security for an enterprise. The certification curriculum also includes wireless domains and the virtual private networking (VPN) with emphasis on the design mechanisms of larger enterprise networks.


The candidate needs to fulfil the prerequisites of being certified as a Cisco Certified Design Associate (CCDA), Cisco Certified Network Associate (CCNA) Routing and Switching, or any Cisco Certified Internetwork Expert (CCIE) certification for taking up this certification exam.

Exam Objective

The 642-874 ARCH exam is divided into five domains that are equally important and critical to be understood. Each domain has different weight age in the exam however it is important to fully cover each subject of every domain. Following are the five domains with their percentage in the exam:

- Advanced Enterprise Campus Networks (30%)

Among the most important domain in terms of exam content coverage, in-depth knowledge on designing advanced enterprise campus networks is a requisite. Under Pass4sure 642-874 this domain, the candidates must know about designing Layer 2 and 3 campus infrastructures and infrastructure services, determining the capacity of IOS software of Cisco in network management and also have knowledge on the considerations to be taken into account for virtualization of enterprise network.

- Advanced IP Addressing and Routing Solutions (24%)

Covering a significant portion of the exam content, this domain requires the candidates to know about designing advanced solution relating to IP addressing and routing for networks in enterprises. This domain requires the candidates to have knowledge on IPv6 to match the considerations for campus design, multicast routing in IPv4, and creating designs for IP addressing, IPv4 routing designs for Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), and Border Gateway Protocol (BGP), and IPv4 security and multicast services.

- WAN Services for Enterprise Networks (8%)

This domain deals with designing WAN services for enterprise network which requires the candidates to know option in Layer 1,2 and 3 WAN connectivity, IPsec VPN technology, evaluating the considerations for WAN service provider designing, and creating VPN designs using the appropriate topologies, technologies and scaling.

- Enterprise Data Center (32%)

The most important domain for the exam is to know the designing of enterprise data center. The candidates need to know best practices for designing data center network infrastructure, technologies and parts of Storage Area Networks (SAN), using Cisco Nexus technology for integrated fabric designs, virtualization technologies for data center networks and servers and designing a modular and flexible data center network.

- Security Services (6%)

Knowing the designing of security services is also an requirement for the exam This domain includes information on creating Network Admission Control (NAC) appliance designs, remote access VPN designs, firewall designs and Intrusion Prevention System (IPS) and Intrusion Detection System designs.

Career Prospects:

A CCDP certificate holder is capable of creating effective internetworks, networks with multilayer-switches and designing architecture for network service. Being a professional certification by Cisco which is global recognized for its integrity and relevance, a CCDP certification can offer a candidate with various specialized job opportunities in the network designing market. Network designing being an important aspect for an effective enterprise network, there is a high demand for network designing professionals and specialists.
