Cisco CCIE SP Content Networking Recertification Set 3

1.

What describes a technique, used to encapsulate voice (NOT data) over ATM?

RFC 1483 LANE AAL-1 RFC 1577

2.

Within a Content Delivery Network there are 3 ways to get a client to the closest Content Engine for delivery of Content. One way is using Simplified Hybrid Routing. The other 2 ways are:

Using WCCP on a router for transparent redirection or setting the proxy settings in a browser point to the
closest Content Engine. Using WCCP on a router for transparent redirection or using DNS to resolve to the correct Content Engine. Using DNS to direct the request to a content router and using a HTTP redirect to have the client go directlyto the Content Engine. Using a Coverage Zone file on the client and then using an HTTP redirect to have the client redirect to theclosest Content Engine. Setting up proxy settings in a browser pointing to the closest CE or using DNS to provide the IP address ofthe closest CE.

3.

A router is set to boot from flash, but cannot find boot commands in the configuration. Also, valid files do not exist in the default flash device. The router will:

Boot from ROM, since there are no valid sources Try to boot from the network, using a default filename Terminate the boot process with an error message Try to boot from the network, then boot from ROM as a backup

4.

In Frame Relay, what devices resend packets that do not transmit correctly?

Digital transmission media cabled to monitor ports, as opposed to straight DCE signaling Network end stations Network switches running SNMP management software Special bridging devices within the backbone cloud

5.

Every time a typing mistake is made at the exec prompt of a router, the message from the router indicates a lookup is being performed. Also, there is a waiting period of several seconds before the next command can be typed. Can this behavior be changed?

No, this is a
built in feature of Cisco IOS software. Yes, use the no ip domain-lookup command. Yes, use the no ip helper-address command. Yes, use the no ip multicast helper-map command. Yes, use the no exec lookup command.

7.

A router is set up to redistribute routing updates from OSPF to RIP. What answer best describes issues the network administrator needs to be aware of?

Split Horizon, Poison Reverse, Holddown Slow convergence, limited hop-count metric, lack of network mask information, periodic broadcasts None, OSPF is a link-state routing protocol which overcomes issues found in RIP. Difference in metrics (e.g. hops vs. cost), subnet mask allocation/addressing (e.g.VLSM vs. fixed subnet mask length), routing
protocol summarization (e.g. network boundaries)

8.

A root CA certificate distinguishes itself from other certificates because:

The root CA certificate has a special bit set in the Key Usage field. The root CA certificate has its serial number in a dedicated range. The root CA certificate issuer and subject are the same. The root CA certificate has a Subject Type equal to CA in its Basic Constraints. The root CA certificate has a Thumbprint.
