1.single-site call processing
2.centralized call processing
3.hybrid call processing
4.distributed call processing

Answer : Select 4

4.

processing model. (Choose two.).

1.VPN connectivity to contractors and suppliers
2.dual connectivity to service providers for Internet access and multiple PRIs to the PSTN

3.
AMFAB is currently using four contiguous registered Class C addresses for their network. AMFAB’s service
provider said it could give AMFAB more address space, but at quite a high cost, and the new addresses would
not be in a contiguous block with the ones AMFAB currently uses. Which option would make the most business
sense for AMFAB?
1.Maintain their current registered address space, obtain one more registered Class C address range for growth,
and deploy RFC 1918 addresses for the new IP telephony solution.
2.Keep the current registered address ranges and migrate internal addresses to RFC 1918 addresses as the
company moves off of the Token Ring network to the Ethernet network.
3.Readdress the network with new registered addresses now so that all the IP address issues can be worked out
prior to the IP telephony deployment.
4.Keep one or two registered address ranges and migrate the entire network over to an RFC 1918 address range
prior to the IP telephony deployment.

Answer : Select 2

4.
To provide the fastest response to an outage in the connection between the access layer, distribution layer and core
of the AMFAB network, what protocols should be deployed?
1.L2 access layer with per-VLAN spanning tree (PVST) with an L2 distribution layer, with common spanning
tree (CST) running with an L3 core, with OSPF in the core
2.L3 at the access and distributions layers running OSPF across a loop-free L2 core with no spanning tree
3.L3 at the access, distribution, and core layers, with OSPF as the routing protocol running on all devices
4.L3 at the access layer running OSPF with the L3 core over the L2 distribution layer
5.L2 at the access layer with per-VLAN spanning tree (PVST) with an L3 distribution layer, which runs OSPF
with an L3 core

Answer : Select 5

5.
During migration from Token Ring to Ethernet, routers will be deployed to allow access between the existing
Token Ring and the new Ethernet networks. Where in the network should these routers be deployed?
1.at the core of the network so that each IDF can continue to use the FDDI backbone
2.in the individual IDFs so that individual users can be migrated from the Token Ring to the Ethernet network to
minimize each individuals down time
3.at each MDF so that each IDF can be migrated separately and avoid possible wide-spread network outages
4.in the computer room so that the Token Ring and Ethernet networks are only connected at one location to
minimize risk

Answer : Select 3

6.Each IDF currently supports a single ring per floor no matter how many different departments are on that
floor.Which VLAN deployment scheme would provide each department with load balancing, high availability,
and security on a per-floor basis?
1.Each department would have a separate data and voice VLAN. Both departmental VLANs would be trunked
over a single path from the IDF to the MDF.
2.Since most departments are small, each department would use a single VLAN for data and voice. Each
departmental VLAN would be trunked from the IDF to the MDF over two paths, a primary and a backup.
3.Each department would use two VLANs, one for data and one for voice. These VLANs would be trunked over
redundant uplinks from the IDF to the MDF
4.Each floor would use two VLANs no matter how many departments are located there. The two VLANs would
have a primary and backup path on each up link from the IDF to the MDF.
