Answer: Option B

Solution:

It provides fallback for IE8.

OSPF is defined on a Frame Relay interface providing point-to-multipoint connections. The remote neighbors can reach this central site, but are complaining of routing failures between each of the remote sites. The central
router has all the routes for each remote site. Based on this information, what can be diagnosed as the biggest potential problem?

An over-subscribed Frame Relay switch will cause some packet loss. ✘ There are problems in the use of OSPF Authentication. ✘ There is an incorrect selection of the Designated Router. ✘ There is an incorrect DLCI assigned on a point-to-point sub-interface. ✔

Within OSPF, what functionality best defines the use of a 'stub' area?

It appears only on remote areas to provide connectivity to the OSPF backbone. ✘ It is used to inject the default route for OSPF. ✘ It uses the no-summary keyword to explicitly block external routes, defines the non-transit area, and usesthe default route to reach external networks. ✘ It is a non-transit area that does not allow flooding of external networks and uses the default route to reachexternal networks. ✔

It provides fallback for IE8.

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

Issue 1Line Type: Interleaved Only

The signal-to-noise margin on the line will not allow downstream DSL rates faster than 640 kbps. If the
subscriber's service was in fact faster at some time, then something has changed in the line characteristics
or noise spectrum. ✘ The subscriber is provisioned for 640 kbps downstream, and the service appears to be working normally.The problem is apparently not related to the DSL (physical layer) part of the service. ✘ The service is running in G.DMT, and 640 kbps is normal for the subscriber's cable length. Change themode to ANSI T1.413 for faster rates. ✘ The DSL profile is set for 16 milliseconds interleave delay. Change the interleave delay to 0, or change theprofile to fastpath for faster line rates. ✔

The following are wire sizes used in telephone company cables. Which will allow the greatest "reach" (distance) in DSL service?

24 AWG (0.5 mm) ✘ 26 AWG (0.4 mm) ✘ A line that is 50% of #24 (0.5mm) and 50 % of #26 (0.4mm). ✘ None of the above will allow enough reach for DSL service. ✔

10.

What is the effect of changing DMT interleaved delay from 16 milliseconds to 2 milliseconds?

Fewer ATM PVCs can be provisioned on the DSL line. ✘ Latency is reduced, but error correction effectiveness may also be reduced. ✘ Latency remains the same, but faster error correction occurs. ✘ Latency remains the same, but throughput is increased. ✔
