Which will allow the greatest “reach” (distance) in DSL service?
The following are wire sizes used in telephone company cables. Which will allow the greatest “reach” (distance) in DSL service?
what is the possible reason why the subscriber’s data rates are slower than usual?
A DSL customer has subscribed to a service that provides 2 mbps downstream and 256 kbps upstream. The cable length is 10 kft (3 km). The customer reports that file transfers on the DSL line seem slower than normal in recent days. After reviewing the DSL profile parameters for the DSL port, and the actual status of the line, what is the possible reason why the subscriber’s data rates are slower than usual?DSLAM#show dsl int atm 1/1DMT profile parametersMaximum Bitrates:Interleave Path: downstream: 2048 kb/s, upstream: 256 kb/sFast Path:

what is a possible cause of this problem?
A subscriber’s DSL service is configured as PPPoA. The subscriber’s DSL modem is trained, but the subscriber can not access the internet (can not ping network addresses or reach web servers). Initial troubleshooting shows that a PPP session is open (active) in the DSL modem and aggregator. Based on these conditions and the symptom, what is a possible cause of this problem?
Which four task items need to be performed for an effective risk assessment and to evaluate network posture?
Assessing your network for potential security risks (risk assessment) should be an integral element of your network architecture. Which four task items need to be performed for an effective risk assessment and to evaluate network posture? (Choose four.)

When using IS-IS for IP routing, Dual IS-IS defined by RFC 1195, what is true? (multiple answer)
The Backup DIS is called:
To eliminate the need for adjacent routers on broadcast networks to form n(n-1)/2 adjacencies, IS-IS defines a pseudonode or Designated Intermediate System, DIS. All router on the broadcast medium form an adjacency with the DIS. The Backup DIS is called:
