These CompTIA N10-009 practice exams include questions that are based on a similar pattern as the finals. This makes it easy for the candidates to understand the CompTIA Network+ Certification Exam (N10-009) exam question paper and manage the time. It is indeed a booster for the people who work hard and do not want to leave any chance of clearing the N10-009 exam with brilliant scores.
NEW QUESTION # 59
A network administrator is troubleshooting a connection issue and needs to determine the path that a packet will take. Which of the following commands accomplishes this task?
Answer: C
Explanation:
The correct answer is traceroute, which is the diagnostic command specifically designed to determine the path a packet takes across a network. According to the CompTIA Network+ N10-009 objectives, traceroute is a key network troubleshooting tool used to identify routing paths, hop counts, and points of latency or failure between a source and a destination.
Traceroute works by sending packets with incrementally increasing Time to Live (TTL) values. Each router along the path decrements the TTL by one, and when it reaches zero, the router returns an ICMP Time Exceeded message. This process allows the administrator to see each intermediate hop, its response time, and where packets may be delayed or dropped.
The other options do not fulfill this purpose. Ping only verifies basic connectivity and round-trip time but does not show the route taken. Netstat displays active connections, ports, and routing tables but does not trace packet paths. Nslookup is used to resolve DNS names to IP addresses, and ipconfig displays local network configuration information.
The Network+ objectives emphasize traceroute (or tracert on Windows systems) as the primary tool for diagnosing routing issues, asymmetric paths, and network congestion, making it the correct and most appropriate choice in this scenario.
NEW QUESTION # 60
SIMULATION
A network technician receives a ticket from an employee who is working on PC 1 but is unable to connect to the database server. The technician pings the database server from PC 1, but the request times out. After reviewing the utilization of Switch 1 and Switch 2, the technician finds high CPU utilization and sees that the MAC table is continuously changing.
INSTRUCTIONS
Configure Switch 1 and Switch 2 to remediate the employee s issue. Then, validate connectivity between PC 1 and the database server.
Switch 1 and Switch 2 are already in configuration mode. Type help to view a list of available commands.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
Answer:
Explanation:
This simulation is based on typical CompTIA Network+ / Cisco-style switch commands used in the PBQ.
The symptoms tell us:
- High CPU + constantly changing MAC table = switching loop
- The links between Switch 1 and Switch 2 (Gi1/1, Gi1/2, Gi2/3, Gi2/4 in the diagram) are not configured as trunks
- VLAN 10 (PCs) and VLAN 20 (servers) must both traverse the link between switches
- The uplinks must be converted to trunk ports to carry both VLANs
Configure Switch 1
On Switch 1, convert the uplinks (Gi1/1 and Gi1/2 based on the diagram) to trunks:
interface gi1/1
switchport mode trunk
switchport trunk allowed vlan 10,20
exit
interface gi1/2
switchport mode trunk
switchport trunk allowed vlan 10,20
exit
Make sure the access ports in the PC side are VLAN 10 and the server side is VLAN 20:
interface gi1/4
switchport mode access
switchport access vlan 10
exit
interface gi1/5
switchport mode access
switchport access vlan 10
exit
Configure Switch 2
On Switch 2, configure the uplinks (Gi2/3 and Gi2/4 from the diagram) as trunks:
interface gi2/3
switchport mode trunk
switchport trunk allowed vlan 10,20
exit
interface gi2/4
switchport mode trunk
switchport trunk allowed vlan 10,20
exit
Configure server ports as VLAN 20:
interface gi2/1
switchport mode access
switchport access vlan 20
exit
interface gi2/2
switchport mode access
switchport access vlan 20
exit
interface gi2/5
switchport mode access
switchport access vlan 20
exit
Validate connectivity
Go back to PC1 and ping the database server ping 192.168.1.31
NEW QUESTION # 61
A company's marketing team created a new application and would like to create a DNS record for newapplication.comptia.org that always resolves to the same address as www.comptia.org. Which of the following records should the administrator use?
Answer: D
Explanation:
A CNAME (Canonical Name) record is used in DNS to alias one domain name to another. This means that newapplication.comptia.org can be made to resolve to the same IP address aswww.comptia.orgby creating a CNAME record pointing newapplication.comptia.org towww.comptia.org. SOA (Start of Authority) is used for DNS zone information, MX (Mail Exchange) is for mail server records, and NS (Name Server) is for specifying authoritative DNS servers.
NEW QUESTION # 62
Which of the following fiber connector types is the most likely to be used on a network interface card?
Answer: B
Explanation:
* Definition of Fiber Connector Types:
* LC (Lucent Connector): A small form-factor fiber optic connector with a push-pull latching mechanism, commonly used for high-density applications.
* SC (Subscriber Connector or Standard Connector): A larger form-factor connector with a push-pull latching mechanism, often used in datacom and telecom applications.
* ST (Straight Tip): A bayonet-style connector, typically used in multimode fiber optic networks.
* MPO (Multi-fiber Push On): A connector designed to support multiple fibers (typically 12 or 24
* fibers), used in high-density cabling environments.
* Common Usage:
* LC Connectors: Due to their small size, LC connectors are widely used in network interface cards (NICs) and high-density environments such as data centers. They allow for more connections in a smaller space compared to SC and ST connectors.
* SC and ST Connectors: These are larger and more commonly used in patch panels and older fiber installations but are less suitable for high-density applications.
* MPO Connectors: Primarily used for trunk cables in data centers and high-density applications but not typically on individual network interface cards.
* Selection Criteria:
* The small form-factor and high-density capabilities of LC connectors make them the preferred choice for network interface cards, where space and connection density are critical considerations.
References:
* CompTIA Network+ study materials on fiber optics and connector types.
NEW QUESTION # 63
A network administrator deploys several new desk phones and workstation cubicles. Each cubicle has one assigned switchport. The administrator run the following commands:
switchport mode access
switchport voice vlan 69
With which of the following VLANs will the workstation traffic be tagged?
Answer: B
Explanation:
On an access port, non-voice (workstation) traffic is placed in the data VLAN (the port's access VLAN); the voice VLAN command only tags IP phone traffic.
