6. Question
What are two WAN connection enhancements that are achieved by implementing PPPoE? (Choose two.)
- Encapsulating Ethernet frames within PPP frames is an efficient use of bandwidth.
- DSL CHAP features are included in PPPoE.
- PPP enables the ISP to assign an IP address to the customer WAN interface.
- An Ethernet link supports a number of data link protocols.
- CHAP enables customer authentication and accounting.

8. Question
Why is the MTU for a PPPoE DSL configuration reduced from 1500 bytes to 1492?
- to enable CHAP authentication
- to reduce congestion on the DSL link
- to accommodate the PPPoE headers
- to establish a secure tunnel with less overhead
9. Question
What are two characteristics of a PPPoE configuration on a Cisco customer router? (Choose two.)
- The PPP configuration is on the dialer interface.
- An MTU size of 1492 bytes is configured on the Ethernet interface.
- The Ethernet interface does not have an IP address.
- The customer router CHAP username and password are independent of what is configured on the ISP router.
- The dialer pool command is applied to the Ethernet interface to link it to the dialer interface.
10. Question
Where is PPPoE configured on a Cisco router?
- on an Ethernet interface
- on the dialer interface
- on a serial interface
- on any physical interface
11. Question
How can the use of VPNs in the workplace contribute to lower operating costs?
- High-speed broadband technology can be replaced with leased lines.
- VPNs can be used across broadband connections rather than dedicated WAN links.
- VPNs prevents connectivity to SOHO users.
- VPNs require a subscription from a specific Internet service provider that specializes in secure connections.
12. Question
How is “tunneling” accomplished in a VPN?
- New headers from one or more VPN protocols encapsulate the original packets.
- All packets between two hosts are assigned to a single physical medium to ensure that the packets are kept private.
- Packets are disguised to look like other types of traffic so that they will be ignored by potential attackers.
- A dedicated circuit is established between the source and destination devices for the duration of the connection.
13. Question
Which two statements describe a remote access VPN? (Choose two.)
- It connects entire networks to each other.
- It requires hosts to send TCP/IP traffic through a VPN gateway.
- It is used to connect individual hosts securely to a company network over the Internet.
- It may require VPN client software on hosts.
- It requires static configuration of the VPN tunnel.
14. Question
Which is a requirement of a site-to-site VPN?
- It requires a client/server architecture.
- It requires the placement of a VPN server at the edge of the company network.
- It requires hosts to use VPN client software to encapsulate traffic.
- It requires a VPN gateway at each end of the tunnel to encrypt and decrypt traffic.
15. Question
What functionality does mGRE provide to the DMVPN technology?
- It allows the creation of dynamically allocated tunnels through a permanent tunnel source at the hub and dynamically allocated tunnel destinations at the spokes.
- It creates a distributed mapping database of public IP addresses for all VPN tunnel spokes.
- It provides secure transport of private information over public networks, such as the Internet.
- It is a Cisco software solution for building multiple VPNs in an easy, dynamic, and scalable manner.
16. Question
Which two scenarios are examples of remote access VPNs? (Choose two.)
- A toy manufacturer has a permanent VPN connection to one of its parts suppliers.
- All users at a large branch office can access company resources through a single VPN connection.
- A mobile sales agent is connecting to the company network via the Internet connection at a hotel.
- A small branch office with three employees has a Cisco ASA that is used to create a VPN connection to the HQ.
- An employee who is working from home uses VPN client software on a laptop in order to connect to the company network.
17. Question
Refer to the exhibit. What solution can provide a VPN between site A and site B to support encapsulation of any Layer 3 protocol between the internal networks at each site?

CCNA4 v6.0 Chapter 3 Exam 002
- a GRE tunnel

18. Question
Which three statements are characteristics of generic routing encapsulation (GRE)? (Choose three.)
- GRE encapsulation supports any OSI Layer 3 protocol.
- GRE is stateless.
- GRE does not have strong security mechanisms.
- The GRE header alone adds at least 24 bytes of overhead.
- GRE provides flow control by default.
