In a hierarchical campus network, the access layer connects end devices such as computers, phones, and wireless access points. True or false?
- A
True
- B
False
A packet needs to travel from a user's local IP network to a different IP network. Which device is primarily responsible for forwarding it between those networks?
- A
A switch, because switches forward packets between IP networks
- B
A router, because routers forward packets between IP networks
- C
A DNS server, because DNS servers forward packets between IP networks
- D
A wireless access point, because access points forward packets between IP networks
A smaller campus combines the distribution and core functions into a .
Select all statements that correctly describe a peer-to-peer model.
- A
A participating device can act as both a requester and a provider.
- B
Every shared resource must be provided by a dedicated central server.
- C
Managing permissions and availability can become harder as the network grows.
- D
Peer-to-peer networks cannot use services such as DNS.
In a data-center spine-and-leaf design, each leaf switch connects to the switches, which interconnect the leaves.
A campus design needs a layer to aggregate access networks and commonly apply routing and policies. Which layer should perform this role?
- A
Access layer
- B
Distribution layer
- C
Core layer
- D
Data-center leaf layer
A small office has devices that share files directly, use cloud applications, and connect to the internet through a router that provides DHCP. Select all statements consistent with this design.
- A
Devices can share resources directly while also using websites or cloud applications hosted as client-server services.
- B
Using client-server services means devices cannot share resources directly.
- C
A router can connect the local network to the internet and may provide address assignment through DHCP.
- D
A router must provide every service used by devices on the network.
What is the name for a smaller campus design that combines the distribution and core functions?
A data center is being designed to support substantial server-to-server traffic using a spine-and-leaf fabric. Which connection arrangement matches this architecture?
- A
Servers connect directly to spine switches, which connect to leaf switches.
- B
Servers connect to routers, and routers interconnect all leaf switches.
- C
Servers connect to leaf switches, and each leaf connects to spine switches.
- D
Servers connect to access-layer switches, which must connect through a campus distribution layer.
What type of network connects a company's local networks at multiple offices to other sites and shared services?
An employee's laptop requests an application hosted in a data center. Explain how this exchange fits the client-server model, then contrast it with peer-to-peer resource sharing. Clarify whether the exchange means every service on the network must use the same model.
At a branch office, which device typically forwards traffic between the local network and the WAN?
- A
A file server
- B
A router or gateway
- C
A leaf switch
- D
A DNS server
A peer-to-peer network may still use centralized services such as a router or DNS server.
- A
True
- B
False
An employee's laptop requests a company application hosted on a server. Which model describes the relationship between the laptop and the application provider?
- A
Peer-to-peer, because the laptop and application exchange data
- B
Client-server, because the laptop requests an application service from a server
- C
Hierarchical campus, because the laptop connects through network layers
- D
Spine-and-leaf, because the application is hosted in a data center
A laptop needs to find the IP address associated with a company application's service name. Which supporting service or device performs that lookup?
- A
DHCP
- B
Router
- C
DNS
- D
Firewall
A company needs its branch offices to reach one another and shared services at a central site. Which network design best describes the connection between the separate office networks?
- A
A wide-area network connecting the offices' local networks
- B
A spine-and-leaf fabric connecting servers within one data center
- C
A peer-to-peer network replacing the need for inter-site connections
- D
A collapsed core combining campus distribution and core functions
In a typical small-office network, what device do phones use to connect to the local network over Wi-Fi?
A campus design team is deciding where to connect employee computers and wireless access points. Which hierarchical campus layer serves that role?
- A
Core layer
- B
Access layer
- C
Distribution layer
- D
Wide-area layer
In a spine-and-leaf data-center fabric, what type of switches connect to each leaf switch and interconnect the leaves?
