1Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)
Administrative distance refers to the trustworthiness of a particular route.
A router first installs routes with higher administrative distances.

The value of the administrative distance can not be altered by the network administrator.
Routes with the smallest metric to a destination indicate the best path.
The metric is always determined based on hop count.
The metric varies depending which Layer 3 protocol is being routed, such as IP or IPX.
2.
Refer to the exhibit. Which statement correctly describes how R1 will determine the best path to R2?
R1 will install a RIP route using network A in its routing table because the administrative distance of RIP is higher than EIGRP.
R1 will install a RIP route using network A in its routing table because the path cost from RIP is lower than EIGRP.
R1 will install an EIGRP route using network B in its routing table because the administrative distance of EIGRP is lower than RIP.
R1 will install an EIGRP route using network B in its routing table because the path cost from EIGRP is lower than RIP.
R1 will install an EIGRP route and a RIP route in its routing table and load balancebetween them.

BGP is a path vector interior routing protocol.
6Which two conditions would create a setting where the use of a distance-vector routing protocol would be efficient? (Choose two.)
the network requires a special hierarchical design

12Which two statements are true regarding metrics? (Choose two.)
RIP uses bandwidth as a metric.
OSPF uses delay as a metric.
EIGRP uses bandwidth as a metric.
OSPF uses cost based on bandwidth as a metric.
RIP uses delay as a metric.
EIGRP uses hop count only as a metric.

14What happens to a static route entry in a routing table when the outgoing interface is not available?
The route is removed from the table.
The router polls neighbors for a replacement route.
The route remains in the table because it was defined as static.
The router redirects the static route to compensate for the loss of the next hop device.
15A router has one static route to each destination network. Which two scenarios would require an administrator to alter the static routes that are configured on that router? (Choose two.)
The destination network no longer exists.
The destination network is moved to a different interface on the same router.
The path between the source and destination is upgraded with a higher bandwidth link.
A topology change occurs where the existing next-hop address or exit interface is not accessible.
The remote destination network interface has to be down for 15 minutes of maintenance.
16Why is it advisable to enter a next-hop IP address when creating a static route whose exit interface is an Ethernet network?
Adding the next-hop address eliminates the need for the router to do any lookups in the routing table before forwarding a packet.
In a multi-access network, the router cannot determine the next-hop MAC address for the Ethernet frame without a next-hop address.
Using a next-hop address in a static route provides a route with a lower metric.
In multi-access networks, using a next-hop address in a static route makes that route a candidate default route.

Packet Tracer Download

Packet Tracer Version 5.3.3 Software Downloads Update 08.02.2012

Packet Tracer version 5.3.3 is a maintenance release that fixes functional and technical issues in the previous versions. It replaces Packet Tracer version 5.3.2.
Packet Tracer 5.3.3 supports activities authored in Packet Tracer 4.x, 5.0.x, 5.1.x, 5.2.x, and 5.3.x. Please note that the last two courses of the CCNA Discovery and CCNA Exploration curricula require Packet Tracer version 4.11 at a minimum, CCNA Security requires version 5.2 at a minimum, and the Packet Tracer Skills Based Assessments require version 5.3.2 at a minimum. The curricula are fully compatible with Packet Tracer 5.3.3.
You can download both the Packet Tracer application and tutorial files in one download package. However, due to the large file size it is faster to download the application by itself, if that is all you need. Choose the download option appropriate for your needs.
Windows:
Title Document Type
Packet Tracer v5.3.3 Application + Tutorial
This is the complete Packet Tracer program including tutorials as a single downloadable package for Windows 2000, XP and Vista.
