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.

7. Question

When PPPoE is configured on a customer router, which two commands must have the same value for the configuration to work? (Choose two.)

dialer pool 2
interface dialer 2
ppp chap password 2
interface gigabitethernet 0/2
pppoe-client dial-pool-number 2
ppp chap hostname 2

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
an IPsec tunnel

Cisco SSL VPN

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.
GRE is the most secure tunneling protocol.
