Here are the answers to Monday's CCNA, CCNP, CCENT, and CCNA Security practice exam questions!
Be sure to read yesterday's posts for a link to a new CCNA Security practice exam!
CCNA Certification:
What configuration register value boots the router into ROM Monitor mode?
A. 0x2142
B. 0x2100
C. 0x2001
D. 0x2102
Answer: 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 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.
Answer: 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 Certification / CCNP ISCW Exam:
Name two major differences between the capabilities between the Basic and Advanced Firewall Wizards in Security Device Manager.
Answer: 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 rules, where the Basic Wizard does not. Here's a screen shot of SDM's Firewall And ACL menu that mentions these differences. (Click the illustration to enlarge.)
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.
Answer: 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 Certification / BCMSN Exam:
What are the two major components of the Cisco Unified Wireless Network?
Answer: Lightweight Access Points and WLAN Controllers.
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
Answers: 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.
I'll have brand-new questions for you later today! Be sure to read yesterday's and today's blog posts for link to new CCNA Security tutorials and practice exams!
