N10-005: Answer 3

Q.  During regular conference sessions, an 802.11g wireless network is overwhelmed with the amount of traffic it needs to process by wireless clients. Most of the additional traffic is from attendees’ mobile devices such as smart phones. What can be done to improve the performance of the wireless network?

A. Use a channel that doesn’t interfere with the smart phones
B. Use channel bonding
C. Switch to the 2.4 GHz frequency band
D. Add MIMO capabilities to the 802.11g network

Answer B is correct. Channel bonding can be used to increase the maximum transfer rate from 54 Mbps to 108 Mbps on 802.11g.
A is incorrect. If cordless telephones were interfering with a wireless networks, changing the channel would reduce the interference. However, smart phones are the wireless clients using the wireless network, and they are not interfering with the wireless network.
C is incorrect. 802.11g uses the 2.4 GHz frequency band already.
D is incorrect. 802.11g does not support multiple-input multiple-output (MIMO) with multiple antennas. MIMO is used with 802.11n.

N10-005: Exam Answer 1

Q.  What can you use to dynamically assign the same IP address to a printer configured as a network device?

A. DNS
B. DHCP reservation
C. SNMP
D. DHCP exclusion

B is correct. Dynamic Host Configuration Protocol (DHCP) is used to dynamically assign IP addresses to network devices including network printers that can be configured as DHCP clients. A DHCP reservation maps the IP address to the printer’s media access control (MAC) address. Once a DHCP reservation is configured,  DHCP will always issue the same IP address to this printer.

A is incorrect. Domain Name System (DNS) is used to resolve host names to IP addresses with A records (also called host records). DNS can also resolve IP addresses to host names with pointer (PTR) records, but it does not assign IP addresses.
C is incorrect. The Simple Network Management Protocol is used to administer and monitor network devices.
Dis incorrect.  A DHCP exclusion would be used if the printer is manually assigned an IP address within a DHCP scope and you want to ensure that the address is not issued to any other DHCP clients.

Objective:  2.3 Explain the purpose and properties of DHCP.

N10-005 Exam: Answer 2

Q.You are troubleshooting a computer system and you determine it has been assigned an IP address of 169.254.45.83. What does this indicate?

A. DNS could not be reached
B. DHCP could not be reached
C. The default gateway could not be reached
D. The computer’s firewall is enabled

Answer B is correct. An address starting with 169.254 is an Automatic Private Internet Protocol Addressing (APIPA) address and is assigned to a Dynamic Host Configuration Protocol (DHCP) client when a DHCP server cannot be reached. Any time you see an APIPA address, you know the computer is a DHCP client and it didn’t receive a DHCP lease.

A is incorrect. Domain Name System (DNS) is used for name resolution and would not cause a system to have an APIPA address.
C is incorrect. The default gateway is assigned by DHCP to a DHCP client and an APIPA address indicates that the client was unable to reach a DHCP server. Also, APIPA addresses do not assign a default gateway.
D is incorrect. Enabling the computer’s firewall would not block DHCP traffic and would not prevent the client from receiving a DHCP address.

Objective:  2.3 Explain the purpose and properties of DHCP.

Q.  What function does DHCP provide on a network?

A. Dynamically assigns IP addresses
B. Resolves host names to IP addresses
C. Translates public IP addresses to private IP addresses
D. Filters traffic based on ACLs

Answer A is correct. Dynamic Host Configuration protocol (DHCP) dynamically assigns IP addresses and other TCP/IP configuration information such as the address of a Domain Name System (DNS) server and the address of the default gateway.
B is incorrect. DNS resolves host names to IP addresses with A (host) resource records.
C is incorrect. Network Address Translation (NAT) translates public IP addresses to private IP addresses and private IP addresses to public IP addresses.
D is incorrect. A firewall will filter traffic in and out of a network using access control lists (ACLs).
Objective:  2.3 Explain the purpose and properties of DHCP.

Q. A company wants to ensure that other mail servers on the Internet can locate its company based email server. What type of record is needed?

A. AAAA
B. MX
C. CNAME
D. PTR
Answer: B is correct. An MX (mail exchange) record is used to locate a mail server and would be configured on a Domain Name System (DNS) server.

A is incorrect. An AAAA (IPv6 host) record provides the name to IPv6 address mapping and is used for forward lookups. If you query DNS with the name of thehost, DNS responds with the IPv6 address of the host.
C is incorrect. A CNAME (canonical name) record is used to give a host an alias so that it can be resolved with more than one fully qualified domain name (FQDN).
D is incorrect. A PTR (pointer) record is used for reverse lookups where a query to DNS includes the IP address of a host, and the DNS server responds with the name of the host.
Objective: 1.7 Summarize DNS concepts and its components.

N10-005 Exam: Answer 2

Q. What can you use to dynamically assign the same IP address to a printer configured as a network device?

A. DNS
B. DHCP reservation
C. SNMP
D. DHCP exclusion

Answer: B is correct. Dynamic Host Configuration Protocol (DHCP) is used to dynamically assign IP addresses to network devices including network printers that can be configured as DHCP clients. A DHCP reservation maps the IP address to the printer’s media access control (MAC) address. Once a DHCP reservation is configured, DHCP will always issue the same IP address to this printer.

A is incorrect. Domain Name System (DNS) is used to resolve host names to IP addresses with A records (also called host records). DNS can also resolve IP addresses to host names with pointer (PTR) records, but it does not assign IP addresses.

N10-005 Exam: Answer 3

Q. You are tasked with purchasing some cable and you have a choice between plenum and non-plenum cable. When would you select plenum cable?

A. When complying with fire codes
B. When connecting two similar devices
C. When connecting dissimilar media
D. When protecting against EMI
Answer: A is correct. Plenum-safe rated cable is used to comply with fire codes when a cable runs through a plenum space. A plenum is a space between walls, in false ceilings, and raised floors. Forced air for heating and air conditioning is commonly sent through the plenum and it’s also possible to run cables through the plenum. Cables are covered with a plastic jacket and this plastic jacket on non-plenum-safe cables can emit toxic fumes if burned. Plenum safe cables have a fire retardant jacket and do not emit toxic fumes.

B is incorrect. A crossover cable is used to connect two similar devices, such as two switches that do not support automatic medium dependent interface crossover (MDIX).

C is incorrect. Media converters or transceivers are used to connect dissimilar media such as an Ethernet cable to a fiber cable.

D is incorrect. Fiber is immune to electromagnetic interference (EMI). Shielded twisted pair (STP) and coax cable are resistant to EMI problems. However, cable identified as plenum-safe is not related to EMI.

Objective: 3.1 Categorize standard media types and associated properties.


N10-005 Exam: Answer 4

Q. You are using Cat 5e cables in your network and recently added a 1 Gbps switch. However, several of the computers are not running at 1 Gbps. Of the following choices, what is the best choice to resolve the problem?
A. Replace the cables with CAT 6
B. Verify the cables with a cable certifier
C. Replace the NICs on the computers
D. Check the cables with a toner probe
Answer: B is correct. A cable certifier is the best choice of those given and it will verify the CAT 5e cables are performing at the CAT 5e specifications. It’s possible for a cable that doesn’t fully meet the specifications to work at 100 Mbps but not at 1000 Mbps.
A is incorrect. Cat 5e cables support 1 Gbps so it not necessary to replace all the cables with CAT 6.

C is incorrect. You may want to ensure that the network interface cards (NICs) support the higher speed and are using auto sense (or auto negotiate). Replacing the NICs wouldn’t be the best choice before testing the cables.

D is incorrect. A toner probe is commonly used to locate the end of a cable in another room, or verify continuity of a cable, but it won’t verify that a cable meets specifications.

Objective: 4.2 Given a scenario, use appropriate hardware tools to troubleshoot connectivity issues.

N10-005 Exam: Answer 5

Q. Of the following choices, what will raise an alarm about a possible attack but not block it?

A. Port scanner
B. IPS
C. IDS
D. Honeypot
Answer: C is correct. An intrusion detection system (IDS) can detect attacks but is typically passive and will not block it. An active IDS can block an attack, though an active IDS is often called an intrusion prevention system (IPS).
A is incorrect. A port scanner can detect open ports but does not detect attacks.

B is incorrect. An IPS will detect and block an attack to prevent a malicious intrusion.

D is incorrect. A honeypot is a system designed to tempt an attacker with false data. An IDS or IPS will often monitor activity on a honeypot, but the honeypot itself doesn’t raise an alarm.

Objective: 5.6 Categorize different types of network security appliances and methods.

Network+ N10-004 and N10-005 Differences

If you're studying for the CompTIA Network+ exam, you probably know there are currently two versions of the exam. The N10-004 exam came out in 2009 and is available until August 31, 2012. The new version (N10-005) has been available since December 2011. A common question whenever a new exam comes out, is what are the differences so I've tried to address some of the differences here.

Networking is a challenging topic. If you're looking for a good book to introduce networking topics and lay a solid foundation, check out this book: Microsoft Windows Networking Essentials. It's a good read with plenty of full-color graphics. Many people buy it with one of Todd Lammle's Network+ books: CompTIA Network+ Study Guide: Exam N10-004 or CompTIA Network+ Study Guide: Exam N10-005.
Realistic practice test questions for the Network+ exam
CompTIA Network+ N10-005 Practice Test Questions (Get Certified Get Ahead)

Domain Differences

The following table shows a comparison of the domains in the two exams. The first thing that stands out is that N10-005 has one less domain. The Network Tools domain was rolled into the Network Management domain. What's not apparent from the table is that many of the objectives have been moved around. For example, the OSI model was in the Network Management domain previously, but it is in the Network Concepts domain now.
N10-004 Domain N10-005 Domain
1.0 Network Technologies (20%) 1.0 Network Concepts (21%)
2.0 Network Media and Topologies (20%) 2.0 Network Installation and Configuration (23%)
3.0 Network Devices (17%) 3.0 Network Media and Topologies (17%)
4.0 Network Management (20%) 4.0 Network Management (20%)
5.0 Network Tools (12%) 5.0 Network Security (19%)
6.0 Network Security (11%)




1.0 Network Concepts

The first domain of the N10-005 exam is Network Concepts. A primary focus here is with the seven layer OSI model. While the OSI model was in the N10-004 exam, there are a couple of differences. First, it adds in the TCP/IP model. Also, it includes the following objective: Classify how applications, devices, and protocols relate to the OSI model layers. You'll need to be able to look at an application, device, or protocol and identify which layer it operates on.

Many of the protocols and ports are similar. However, the new exam digs into Domain Name System (DNS) a little more. You'll need to know the different types of records and what dynamic DNS is. Troubleshooting methodologies are added but these are largely the same as they were in Domain 4 in the previous exam.

A completely new topic 1.9 Identify virtual network components. Virtualization is widely used and important to understand. Interestingly, they indirectly added a reference to cloud computing with Network as a Service (NaaS).

2.0 Network Installation and Configuration

This topic includes many of the objectives from the Network Devices domain in the previous domain. However, it does expand on some topics such as Dynamic Host Configuration Protocol (DHCP). Many people commonly remember that DHCP provides IP addresses, but it does much more and the objectives identify topics such as reservations, scopes, leases, and options.

This topic also adds in troubleshooting topics for wireless networks and common router and switch problems. Most of these topics were in the Network Management domain previously.

3.0 Network Media and Topologies

This domain includes many of the same topics as the Network Media and Topologies domain in the previous exam. However, there is an important difference. In the previous exam, the objective often included the word identify or categorize. However, in the new exam, these words have sometimes been replaced with describe, or compare and contrast. These imply additional depth for the topics.

For example, instead of just being able to identify common physical network topologies such as Star or Ring, you're expected to be able to describe them. If you're asked to point to a square peg or a round hole, that requires one level of knowledge. However, it is a little more difficult to describe a square peg or a round hold.

4.0 Network Management

While the previous exam had a domain labeled as Network Management, many of the objectives are not the same. That's not to say that all of the objectives in the N10-005 Network Management domain are new. They aren't. Instead, objectives have just been moved around. As mentioned earlier, the Network Tools domain was rolled into this domain. Additionally, some of the specialized network devices topics from the Network Devices domain were put into here. Some of the other objectives have been reworded with a different emphasis, but the core objectives are the same.

Pass the Security+ exam the first time you take it



5.0 Network Security

The first thing to notice here is that security has become much more important. It was only 11 percent of the previous exam, but is 19 percent in current exam. Security is an important part of any network administrator's job and this reflects the growing importance of security.

Wireless security topics have been added and placed right at the beginning, and again in objective 5.4. This makes a lot of sense since wireless networks are so common and people often implement them with weak security.

The objective related to firewalls has different wording. Instead of just expecting you to explain common features of a firewall, the new objectives expect you to be able to install and configure a basic firewall. You'll still be expected to explain the common features, but you should have deeper knowledge of firewalls.

Summary

In summary, there are quite a few differences between the N10-004 and N10-005 exams. If you're studying for Network+, ensure you are studying the relevant materials for the exam you plan on taking. Also, if you're studying for the N10-004 exam, ensure you take it before the exam retires on August 31, 2012.

Good luck.

Best of luck in your studies,
