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.
Fill in the blank.
DOCSIS specifies the MAC sub-layer as a Layer 2 requirement that defines either a deterministic access method, TDMA, or S-CDMA.
How is voice traffic affected when the customer uses ADSL technology?
No special equipment is needed to separate voice and data signals.
Voice traffic is interrupted if the ADSL service fails.
ADSL signals can distort voice transmissions.
Voice signals are on a separate wire pair from ADSL signals.
What functionality is required on routers to provide remote workers with VoIP and videoconferencing capabilities?
Which networking technology will ensure reliable and secure remote access when a teleworker connects to a corporate network?
an encrypted VPN tunnel
routers with QoS capability
a VoIP and videoconferencing capable connection
broadband (cable or DSL) access to the corporate network
In which layer of the TCP/IP protocol model does IPsec apply security to network data?
What are two Layer 2 WAN technologies that can provide secure remote connections between corporate branch offices? (Choose two.)
Which two network components does a teleworker require to connect remotely and securely from home to the corporate network? (Choose two.)
VPN client software or VPN-enabled router
multifunction security appliance
broadband Internet connection
VPN server or concentrator
Which two OSI Layer 1 specifications does DOCSIS define for a cable Internet connection? (Choose two.)
a deterministic media access method
VPN tunneling requirements
the separation of the voice and data transmissions
Which cable network communication technology is secure, extremely resistant to noise, and employs spread-spectrum technology?
Which technology provides a secure connection between a SOHO and the headquarters office?
Which standard specifies the channel frequencies and the deterministic access method of cable networks?
What advantage does DSL have compared to cable technology?
DSL upload and download speeds are always the same.
DSL is faster.
DSL has no distance limitations.
DSL is not a shared medium.
Which medium is used for delivering data via DSL technology through PSTN?
Which DSL technology provides higher downstream bandwidth to the user than upstream bandwidth?
Which broadband wireless technology is based on the 802.11 standard?
Which type of long distance telecommunication technology provides point-to-point connections and cellular access?
What are two disadvantages of employing teleworkers in an organization? (Choose two.)
increased usage of sick or vacation days
increased difficulty of tracking task progress
slower customer service response times
the need to implement a new management style
increase in office expenses
A company is looking for the least expensive broadband solution that provides at least 10 Mb/s download speed. The company is located 5 miles from the nearest provider. Which broadband solution would be appropriate?
Which broadband technology would be best for a user that needs remote access when traveling in mountains and at sea?
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
Fill in the blank. Use only an acronym. PPPoE creates a PPP tunnel through the DSL connection for the purpose of sending PPP frames.
