CompTIA N10-008 Online Questions & Answers

• Question 771:

  Which of the following would be used when connecting devices that have different physical characteristics?

  A. A proxy server
  B. An industrial control system
  C. A load balancer
  D. A media converter
  D. A media converter

  ---

  Explanation/Reference:

  A media converter converts the signal from one media type (e.g., copper Ethernet) to another media type (e.g., fiber Ethernet). Devices that have different physical characteristics (i.e., different Layer 1 mediums) have to use a media converter for proper communication between them.

• Question 772:

  Which of the following combinations of single cables and transceivers will allow a server to have 40GB of network throughput? (Select two).

  A. SFP+
  B. SFP
  C. QSFP+
  D. Multimode
  E. Cat 6a
  F. Cat5e
  C. QSFP+
  D. Multimode

  ---

  Explanation/Reference:

  QSFP+ is a type of transceiver that supports 40 gigabit Ethernet (40GbE) over four lanes of 10 gigabit Ethernet (10GbE) each. QSFP+ stands for quad small form-factor pluggable plus, and it is a compact and hot-swappable module that plugs into a QSFP+ port on a network device. QSFP+ transceivers can support various types of cables and connectors, such as direct attach copper (DAC), active optical cable (AOC), or fiber optic cable. Multimode is a type of fiber optic cable that supports multiple modes of light propagation within the core. Multimode fiber optic cable can carry higher bandwidth and data rates than single-mode fiber optic cable, but over shorter distances. Multimode fiber optic cable is commonly used for short-reach applications, such as within a data center or a campus network. Multimode fiber optic cable can be paired with QSFP+ transceivers to achieve 40GbE connectivity. The other options are not correct because they do not support 40GbE. They are: SFP+. SFP+ is a type of transceiver that supports 10 gigabit Ethernet (10GbE) over a single lane. SFP+ stands for small form-factor pluggable plus, and it is a compact and hot-swappable module that plugs into an SFP+ port on a network device. SFP+ transceivers can support various types of cables and connectors, such as direct attach copper (DAC), active optical cable (AOC), or fiber optic cable. However, SFP+ transceivers cannot support 40GbE by themselves, unless they are used in a breakout configuration with a QSFP+ transceiver. SFP. SFP is a type of transceiver that supports 1 gigabit Ethernet (1GbE) over a single lane. SFP stands for small form-factor pluggable, and it is a compact and hot-swappable module that plugs into an SFP port on a network device. SFP transceivers can support various types of cables and connectors, such as twisted- pair copper, coaxial cable, or fiber optic cable. However, SFP transceivers cannot support 40GbE by themselves, unless they are used in a breakout configuration with a QSFP+ transceiver. Cat 6a. Cat 6a is a type of twisted-pair copper cable that supports 10 gigabit Ethernet (10GbE) over distances up to 100 meters. Cat 6a stands for category 6 augmented, and it is an enhanced version of Cat 6 cable that offers better performance and reduced crosstalk. Cat 6a cable can be paired with 10Gbase-T transceivers to achieve 10GbE connectivity. However, Cat 6a cable cannot support 40GbE by itself, unless it is used in a breakout configuration with a QSFP+ transceiver. Cat 5e. Cat 5e is a type of twisted-pair copper cable that supports 1 gigabit Ethernet (1GbE) over distances up to 100 meters. Cat 5e stands for category 5 enhanced, and it is an improved version of Cat 5 cable that offers better performance and reduced crosstalk. Cat 5e cable can be paired with 1000base-T transceivers to achieve 1GbE connectivity. However, Cat 5e cable cannot support 40GbE by itself, unless it is used in a breakout configuration with a QSFP+ transceiver.

• Question 773:

  Which of the following layers of the OSI model lies between the transport layer and the network layer?

  A. Application
  B. Data link
  C. Session
  D. Presentation
  D. Presentation

• Question 774:

  An organization would like to implement a disaster recovery strategy that does not require a facility agreement or idle hardware. Which of the following strategies MOST likely meets the organization's requirements?

  A. Cloud site
  B. Cold site
  C. Warm site
  D. Hot site
  A. Cloud site

  ---

  Explanation/Reference:

  They want no binding contract with a building and they want no hardware, therefore Cloud is the best and only option the company wants.

• Question 775:

  A store owner would like to have secure wireless access available for both business equipment and patron use. Which of the following features should be configured to allow different wireless access through the same equipment?

  A. MIMO
  B. TKIP
  C. LTE
  D. SSID
  D. SSID

  ---

  Explanation/Reference:

  The feature that should be configured to allow different wireless access through the same equipment is SSID (Service Set Identifier). SSID is a unique identifier that allows wireless devices to connect to a wireless network. By configuring multiple SSIDs, the store owner can provide separate wireless access for business equipment and patron use, while using the same wireless access points

• Question 776:

  A network engineer configured new firewalls with the correct configuration to be deployed to each remote branch. Unneeded services were disabled, and all firewall rules were applied successfully. Which of the following should the network engineer perform NEXT to ensure all the firewalls are hardened successfully?

  A. Ensure an implicit permit rule is enabled
  B. Configure the log settings on the firewalls to the central syslog server
  C. Update the firewalls with current firmware and software
  D. Use the same complex passwords on all firewalls
  C. Update the firewalls with current firmware and software

• Question 777:

  A network administrator is configuring a static DSL connection on the perimeter router to use a backup route to the fiber connection using OSPF routing. The administrator notices all traffic is going over the DSL connection and both links are working. Which of the following should the administrator do to adjust the routing settings for the fiber connection to be used by the router?

  A. Add the DSL connection to the neighbor table for OSPF protocol
  B. Change the routing protocol to EIGRP for the fiber connection
  C. Increase the administrative distance of the DSL connection
  D. Create a separate VLAN for the DSL connection
  C. Increase the administrative distance of the DSL connection

  ---

  Explanation/Reference:

  Administrative distance is a metric used by routers to determine the preference of a route. The lower the administrative distance, the higher the preference. By increasing the administrative distance of the DSL connection, the router will prefer the fiber connection since it has a lower administrative distance.

  B. STP
  C. Flow control
  D. CSMA/CD
  B. STP

  ---

  Explanation/Reference:

  STP (Spanning Tree Protocol) A switching protocol that prevents network loops by dynamically disabling links as needed.

  A. Access control vestibule
  B. Palm scanner
  C. PIN pad
  D. Digital card reader
  E. Photo ID
  B. Palm scanner

  ---

  Explanation/Reference:

  A palm scanner is a security method that uses physical characteristics of a person, specifically the unique features of their palm or hand, to authorize access to a location. This biometric method is based on the individual's palm print, which is unique to each person.
