These sample questions will make you very familiar with both the type and the difficulty level of the questions on the N10-009 certification test. To get familiar with real exam environment, we suggest you try our Sample CompTIA Network+ Certification Practice Exam. This sample practice exam gives you the feeling of reality and is a clue to the questions asked in the actual CompTIA Network+ certification exam.
These sample questions are simple and basic questions that represent likeness to the real CompTIA N10-009 exam questions. To assess your readiness and performance with real time scenario based questions, we suggest you prepare with our Premium CompTIA Network+ Certification Practice Exam. When you solve real time scenario based questions practically, you come across many difficulties that give you an opportunity to improve.
CompTIA N10-009 Sample Questions:
01. After an access switch was added to a campus, users across several buildings report brief but repeated interruptions. Switch logs show the layer two topology recalculating repeatedly, and the newly added switch is being elected as the root of the tree.
Which action addresses the cause?
a) Set the bridge priority so the intended core switch is elected root, and protect that role
b) Move the newly added switch onto its own VLAN so it no longer affects the other buildings
c) Increase the port speed on the uplinks so the topology converges before users notice
d) Disable the loop prevention protocol on the newly added switch so it stops participating
02. Three separate faults are open: a suspected break in a patch lead, an application that fails only for certain requests, and a wireless cell where users report drops in one corner of the floor. Which two tool choices correctly match a fault?
(Choose two.)
a) A Wi-Fi analyzer for the suspected break in the patch lead
b) A cable tester for the application that fails only on certain requests
c) A protocol analyzer for the wireless cell with drops in one corner
d) A protocol analyzer for the application that fails only on certain requests
e) A cable tester for the suspected break in the patch lead
03. A WAN link runs at capacity every afternoon. Management asks which internal hosts and which applications are consuming the bandwidth, covering the whole of last month. Storage for monitoring data is limited. Which data source answers the question?
a) Packet captures taken at the router, storing the full contents of every frame observed
b) Flow data exported by the router, summarizing conversations by address, port and volume
c) System logs collected from the router, recording configuration and state change events
d) Interface counters polled by SNMP, recording the volume passing each interface
04. Several users on one floor report that the network is unusable. The technician wants to establish whether the problem is physical before examining any configuration. Which two checks belong to that first pass?
(Choose two.)
a) Confirm the link and activity indications on the affected switch ports
b) Confirm the VLAN assigned to each affected port matches the documented plan
c) Review the interface error counters on the switch serving that floor
d) Inspect the address pool on the server to see whether free addresses remain
e) Compare the access control lists applied to the floor against the approved baseline
05. A manufacturer runs supervisory control systems that operate plant machinery. Several of the controllers run software that can no longer be patched, and the vendor will not certify changes to them. The plant systems must still send production figures to a reporting server on the business network.
Which approach best manages the risk?
a) Place the control systems on the business network and rely on endpoint protection for each
b) Replace the unpatchable controllers immediately so the estate returns to a supported state
c) Apply the outstanding patches during the next maintenance window and monitor the result
d) Segment the control systems onto their own network and permit only the reporting flow outward
06. Two buildings four hundred meters apart must be joined by a wireless bridge across an open car park. A first attempt using the access points' standard antennas produced an unreliable link, and a survey shows several unrelated wireless networks radiating across the same area.
Which antenna choice should the design use at each end?
a) An omnidirectional antenna at full height, radiating the signal evenly in every direction
b) A directional antenna aimed at the far building, concentrating the signal along one path
c) An omnidirectional antenna with the transmit power raised to cover the extra distance
d) A directional antenna aimed upward, lifting the signal above the obstructions in the path
07. An organization is replacing individually granted permissions, which have accumulated unevenly as staff changed jobs, with role-based access control. Which two statements describe how the new model works?
(Choose two.)
a) Each user is granted permissions directly, and a role records what they were given
b) Every role is granted full access, and restrictions are applied to individuals
c) Moving a user between roles replaces their permissions rather than adding to them
d) Permissions attach to a role, and users receive them by holding that role
e) Permissions attach to the device a user signs in from rather than to the account
08. Users in one part of a warehouse report that their wireless connections slow down and drop whenever the adjacent machinery is running, while coverage readings at those locations remain strong.
Which cause fits?
a) Interference from the machinery is degrading the signal despite adequate coverage
b) Excessive client density in that part of the warehouse is exhausting the available airtime
c) An incorrect channel width on the access point is reducing the throughput available
d) Insufficient coverage in that part of the warehouse is leaving clients at the cell edge
09. An organization forwards the logs from its routers, switches, firewalls, and servers to a single central platform. Which two benefits follow directly from that consolidation?
(Choose two.)
a) Devices generate fewer log entries because the platform filters them at the source
b) Log data is retained independently of the device that produced it
c) Configuration changes are automatically reverted when a log entry indicates a fault
d) Clock differences between devices are eliminated as entries arrive at the platform
e) Events from different devices can be correlated onto one timeline
10. On a morning when an unusually large number of visitors are on site, new devices joining the guest network fail to obtain an address, while devices that joined earlier continue to work normally. Which cause fits?
a) The wireless controller has reached the number of clients configured for the guest network
b) The address server has failed, so it can no longer answer any client request
c) The address pool for the guest segment has been exhausted by the number of clients
d) The guest segment has been placed behind a rule that blocks the address protocol
