1. Which three actions might a Frame Relay switch perform when it detects an excessive build-up of frames in its queue? (Choose three.)
puts a hold on accepting frames in excess of the CIR
drops frames from the queue that have the DE bit set
reduces the number of frames it sends over the link
re-negotiates flow control with the connected device
sets the FECN bit on all frames it receives on the congested link
sets the BECN bit on all frames it places on the congested link
2. Which best describes the benefit of using Frame Relay as opposed to a leased line or ISDN service?
Customers can define their virtual circuit needs in far greater combinations, with increments as small as 64 kbps.
Customers pay for an end-to-end connection that includes the local loop and the network link.
Customers only pay for the local loop and the bandwidth they purchase from the network provider.
Connecting new sites requires new lower cost circuit installations when compared to ISDN dialup costs or adding additional hardware for leased service.

Inverse-ARP will now add an entry for 10.1.1.1 into the Frame Relay map table using DLCI 22.

proposal can the account manager refer to when discussing this issue with the store manager?(Choose two.)

the project scope

the bill-of-material

the project timeline

the terms and conditions

VPN cannot be configured and established between the branch location and the main office. It is
determined that the router at the main office does not have enough memory and does not have
the correct Cisco IOS version image to support the VPN features. To prevent this delay, this
problem should have been identified and corrected during which part of the design project?

the preparation of the business case

the prioritizing of the technical goals

the characterization of the existing network

12
AAA Financial Services Company is performing implementation planning
for a core switch upgrade. The company has 200 financial software programmers that work
billable hours during the week. They have critical, scheduled money transfer transmissions that
occur at hourly intervals every night. There are two, two-hour long IT maintenance windows
scheduled for software upgrades, one on Saturday and one on Sunday. The bank advertises
online banking as available 24 hours on business days and 21 hours on the weekends. However,
a network upgrade that is necessary to replace some switches is expected to take four hours.
Because of rack constraints, this time includes three hours to remove the old switches before the
new switches can be installed and one hour to test the logical configuration. How should the
implementation scheduling be handled

Defer the software upgrades. Use the Saturday window to perform the hardware
installation. Use the Sunday window to perform the logical testing.

Coordinate and publish a separate four-hour downtime during Friday to perform the
complete switch installation and testing process. Use the Saturday and Sunday windows to
correct any outage problems after the Friday window.

Coordinate and publish two, four-hour downtimes incorporating the published Saturday
and Sunday windows. Defer any software upgrades until the new network is proven to be working
correctly with the old software. Use the Sunday window as a fallback scheduling period if there
are problems necessitating backing out of the Saturday window.

Coordinate and publish an eight-hour downtime incorporating the Saturday window. This
will allow four hours for installation and logical testing, one hour for troubleshooting and decision,
and three hours to roll back to the previous configuration if the new switching cannot pass the
logical testing. Defer any software upgrades until the new network is proven to be working
correctly with the old software.

20
Which statement describes a phased installation into an existing network?

A phased installation generally takes less time and expense than a green-field installation.

A phased installation requires detailed planning in order to avoid disruption of user services.
A phased installation involves building an entire replacement network and migrating users
over to it.
