Let’s test your knowledge of important Cisco certification exam topics from ROM Monitor mode to loopback addresses! Answers are listed at the end of the article. Good luck!

CCNA Certification:

What configuration register value boots the router into ROM Monitor mode?

A. 0x2142

B. 0x2100

C. 0x2001

D. 0x2102

CCENT Certification:

If an IP address has a first octet of 127, what can you assume regarding that address?

A. The address is reserved for loopbacks.

B. The address is from one of the reserved address ranges for Class A, B, and C addresses.

C. The address can be assigned to a Cisco router's loopback interface.

D. The address is not a reserved address of any kind.

CCNA Security Certification / CCNP ISCW Exam:

Name two major differences between the capabilities between the Basic and Advanced Firewall Wizards in Security Device Manager.

CCNP Certification / BSCI Exam:

Identify the correct statements regarding the contents of the EIGRP route table.

A. Multiple successors are a possibility.

B. Multiple feasible successors are a possibility.

C. There can be only one successor in this table.

D. There can be only one feasible successor in this table.

E. Successors cannot be found in this table.

F. Feasible successors cannot be found in this table.

CCNP Certification / BCMSN Exam:

What are the two major components of the Cisco Unified Wireless Network?

CCNP / ONT Exam:

Identify the true statements regarding traffic shaping.

A. Drops excess packets without exception

B. Queues excess packets whenever possible

C. Only incoming traffic can be shaped

D. Only outgoing traffic can be shaped

E. Both incoming and outgoing traffic can be policed

F. Generally results in fewer TCP retransmissions than traffic policing

G. Generally results in more TCP retransmissions than traffic policing

Here are the answers!

CCNA: B. The config register setting 0x2100 will have the router boot into ROM Monitor mode.

0x2142 will have the router ignore the contents of NVRAM when it boots; that means the starting configuration is ignored.

The default config register setting is 0x2102, which means the router will look in NVRAM for a valid startup configuration file and to Flash for a valid IOS image.

CCENT: A. An address that begins with 127 is reserved for loopbacks, but not for Cisco router loopbacks - you can't assign an address from this range to a Cisco loopback interface.

CCNA Security / ISCW Exam: The Advanced Wizard allow you to configure multiple outside interfaces as well as a DMZ. The Basic Wizard allows neither of these. Additionally, the Advanced Wizard allows you to define your own customized inspection rules, where the Basic Wizard does not.

CCNP / BSCI Exam: A. You can have multiple successors in the EIGRP route table if the successors have the exact same metric. You can see feasible successors in the routing table if the variance command is in effect, but the question did not mention that command.

CCNP / BCMSN Exam: Lightweight Access Points and WLAN Controllers.

CCNP / ONT Exam: B, D, F. Traffic shaping queues excess packets whenever possible, and only outgoing traffic can be shaped. Since we're generally not dropping as many packets with traffic shaping as we will with traffic policing, there will be few TCP retransmissions with traffic shaping.
