CCNA Synopsis

SYNOPSIS

The Cisco Certified Network Associate (CCNA) exam is an entry-level certification designed for network administrators and engineers. It can be taken in one of two forms. First, the CCNA can be taken in one, single exam - The CCNA Composite 640-802. Second, it can be taken as a two part exam designated Interconnecting Cisco Network Devices 1 and 2 (ICND1 and ICND2).

A majority of the professional networking world consider the CCNA to be the defacto Network Engineering exam that qualifies a user to operate a small to medium business network. Furthermore, the CCNA opens doors for new exams, such as the CCNP (Cisco Certified Network Professional) and CCDP (Cisco Certified Design Professional) certifications. Therefore, the exam is not in any way easy.

Overall, the CCNA has several subjects that it covers in detail, but the primary subjects of concern are Routing and Switching, including but not limited to the use of: IP, IGRP, Serial, Frame Relay, IP RIP, VLANs, RIP, Ethernet, and access lists. After attaining the CCNA, the exam is valid for three years before it must be recertified.

14 What 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.

15 A 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.

16 Why 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.
