It's Wednesday, July 2, and here are the answers to yesterday's Cisco certification exam training questions!
Be sure to read today and yesterday's blog postings for a link to a new CCNA Security tutorial, as well as the latest information on the new CCNA Security, Wireless, and Voice certifications - and what you need to do NOW to take advantage of these opportunities!
CCNA Certification:
The term used for an OSPF path metric is ____________ .
Answer: cost.
CCNA Security:
What program is found in the following screen shot?
Answer: This is SDM, the Security Device Manager. My upcoming CCNA Security Study Package will have several hundred SDM screen shots for you, showing you exactly how to carry out any task you may see on the exam or on the job!

CCENT Certification:
Short answer: What layer(s) in the TCP/IP networking model map to the Data Link layer in the OSI model?
Answer: The TCP/IP model has a single layer, the Network Access layer, that actually maps to both the Physical and Data Link layers of the OSI model.
CCNP Certification / BSCI Exam:
In ISIS, what is the most efficient point of a network at which to perform route summarization?
A. An L1 router.
B. An L2 router.
C. An L1/L2 router.
D. A DIS router.
Answer: C. L1/L2 routers are area boundary routers in ISIS, and this is the most efficient point at which to configure route summarization.
CCNP Certification / BCMSN Exam:
Short answer: An HSRP router is the primary router and it has a priority of 100. Another router comes online in the same group and it has a priority of 107. Does the new router become the primary?
If so, why?
If not, what additional configuration is needed to make it the primary?
Answer. By default, the new router with the higher priority will not become the primary router. To allow a router with a higher priority to take over the role of HSRP primary from an existing and normally functioning primary, the preempt option must be configured on the router with the higher priority.
Let's use a two-router HSRP deployment as an example. R2 is the standby, R3 is the primary ("active"), and both have an HSRP priority of 100. Raising R2's priority to 150 does not automatically make it the primary, as shown below.
R2(config)#interface ethernet0
R2(config-if)#standby 5 priority 150
R2#show standby
Ethernet0 - Group 5
Local state is Standby, priority 150
Hellotime 4 sec, holdtime 12 sec Next hello sent in 0.896
Virtual IP address is 172.12.23.10 configured
Active router is 172.12.23.3, priority 100 expires in 8.072
Standby router is local 1 state changes, last state change 00:14:24
R2 now has a higher priority, but R3 is still the active router. R2 will not take over as the HSRP primary until R3 goes down - OR the preempt option is configured on R2.
R2(config-if)#standby 5 priority 150 preempt
1d11h: %STANDBY-6-STATECHANGE: Ethernet0 Group 5 state Standby -> Active
R2#show standby
Ethernet0 - Group 5
Local state is Active, priority 150, may preempt
Hellotime 4 sec, holdtime 12 sec Next hello sent in 1.844
Virtual IP address is 172.12.23.10 configured
Active router is local
Standby router is 172.12.23.3 expires in 10.204
Virtual mac address is 0000.0c07.ac05 2 state changes, last state change 00:00:13
CCNP Certification / ISCW Exam:
What is the purpose of the 256MB.sdm file?
Answer: This preconfigured signature file is a popular choice for IPS configurations, since this file contains the latest and greatest signatures. Signatures from this file can be edited.
CCNP Certification / ONT Exam:
Name the two reserved CoS values.
Answer: 110 (Internet) and 111 (Network). Those are binary expressions.
New questions posted later today!
