01. Which part of design methodology is important for identifying organizational goals?
a) Existing network and sites characterization
b) Conceptual architecture examination
c) Design of the network topology and solutions
d) Customer requirements identification
e) Design validation
02. Which two tasks are parts of characterizing an existing network?
a) Using design tools to create a framework for the design
b) Collecting information using the existing documentation and direct organizational input
c) Using tools for automated auditing of the network
d) Identifying the business objectives of the organization
03. Which two of these reasons explain why you would modularize?
a) To reduce the amount of data that the network device needs to process
b) To increase the amount of data that the network device needs to process
c) To reduce the amount of data that the engineer must manage
d) To increase the amount of data that the engineer must manage
e) To make it easier to have multiple routing protocols running in the network
04. Which two of these reasons explain why the hub-and-spoke topology is the basis for hierarchical design?
a) It has better convergence than ring topology
b) It is the only topology compatible with Cisco devices
c) It scales better than full-mesh topology
d) It is the only standardized topology
e) It was invented before full-mesh and ring topologies
05. Which statement is true about a good IPv4 addressing plan?
a) Each individual point-to-point link should have its own separate /24 subnet
b) The user subnets size should always be designed for best fit because you can always allocate more addresses later
c) The management subnet should only be allocated after all other addressing is designed and implemented
d) You should dedicate a separate subnet for remote access
06. Which two statements about IPv6 addressing are true?
a) The best way to subnet a /48 IPv6 prefix is to use IPv4 addresses and translate them from decimal to hexadecimal
b) Stateless autoconfiguration works with prefixes between /40 and /64
c) If you need a provider-independent address, you will need to go directly to IANA
d) /48 is a typical prefix that RIR or ISP assigns to you
e) If you use both IPv4 and IPv6 in your network, you want to strive to have a dual-stack network
07. Which two statements are true about campus design?
a) For optimal distribution-to-core layer convergence, you should build triangles, not squares
b) Peering across the access layer should be limited as much as possible
c) Summarization within the campus network should be avoided
d) Within the campus, CEF should be disabled to get the best convergence
e) Summarization should not be performed at the boundary where the distribution layer of each building connects to the core
08. Which statement is true about VPNs?
a) With Layer 2 VPNs, the customer exchanges routes with SP routers
b) Examples of Layer 3 VPNs are VPLS and VPWS
c) With a Layer 2 VPN, the enterprise will maintain control over Layer 3 policies
d) From a provider perspective, Layer 2 VPNs are the most scalable solution
09. What are three properties and one-way requirements for voice traffic?
c) Latency should be below 400 ms
d) Latency should be below 150 ms
e) Bandwidth required is roughly between 30 and 128 kbps
f) Bandwidth required is roughly between 0.5 and 20 Mbps
10. What are the main benefits of Cisco ACI?
a) Made by Cisco
b) Centralized application policy management
c) Requires that engineers configure each network device separately
d) Provides a platform-as-a-service infrastructure for running your applications
