2. Question

Which network scenario will require the use of a WAN?

Employees need to connect to the corporate email server through a VPN while traveling.
Employees in the branch office need to share files with the headquarters office that is located in a separate building on the same campus network.
Employees need to access web pages that are hosted on the corporate web servers in the DMZ within their building.

3. Question

Which statement describes a characteristic of a WAN?

A WAN operates within the same geographic scope of a LAN, but has serial links.
WAN networks are owned by service providers.
All serial links are considered WAN connections.
A WAN provides end-user network connectivity to the campus backbone.

4. Question

What are two common types of circuit-switched WAN technologies? (Choose two.)

6. Question

What is a requirement of a connectionless packet-switched network?

Each packet has to carry only an identifier.
The network predetermines the route for a packet.
Full addressing information must be carried in each data packet.
A virtual circuit is created for the duration of the packet delivery.

7. Question

What is an advantage of packet-switched technology over circuit-switched technology?

Packet-switched networks are less susceptible to jitter than circuit-switched networks are.
Packet-switched networks can efficiently use multiple routes inside a service provider network.
Packet-switched networks do not require an expensive permanent connection to each endpoint.
Packet-switched networks usually experience lower latency than circuit-switched networks experience.
