CompTIA N10-008 Online Questions & Answers

• Question 381:

  A network administrator requires redundant routers on the network, but only one default gateway is configurable on a workstation. Which of the following will allow for redundant routers with a single IP address?

  A. EIGRP
  B. VRRP
  C. MPLS
  D. STP
  B. VRRP

  ---

  Explanation/Reference:

  VRRP (Virtual Router Redundancy Protocol) is a protocol that provides a way to have redundant routers on a network, allowing for a single default gateway IP address to be configured on workstations. In a VRRP setup, multiple routers share a virtual IP address and a virtual MAC address. One router is elected as the master, and if it fails, another router takes over, ensuring continuous network connectivity.

  Options A (EIGRP), C (MPLS), and D (STP) are not specifically designed for providing redundant routers with a single IP address for workstations. EIGRP is a routing protocol, MPLS is a networking technology, and STP (Spanning Tree Protocol) is used for loop prevention in Ethernet networks.

  To troubleshoot all the network components and review the cable test results, you can use the following steps:

  Click on each device and cable to open its information window. Review the information and identify any problems or errors that may affect the network connectivity or performance. Diagnose the appropriate component(s) by identifying any components with a problem and recommend a solution to correct each problem. Fill in the remediation form using the drop-down menus provided. Here is an example of how to fill in the remediation form for PC1. The component with a problem is PC1. The problem is Incorrect IP address.

  The solution is Change the IP address to 192.168.1.10. You can use the same steps to fill in the remediation form for other components.

  To enter commands in each device, you can use the following steps:

  Click on the device to open its terminal window.

  Enter the command ipconfig /all to display the IP configuration of the device, including its IP address, subnet mask, default gateway, and DNS servers. Enter the command ping to test the connectivity and reachability to another device on the network by sending and receiving echo packets. Replace with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1. Enter the command tracert to trace the route and measure the latency of packets from the device to another device on the network by sending and receiving packets with increasing TTL values. Replace with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1. Here is an example of how to enter commands in PC1. Click on PC1 to open its terminal window.

  Enter the command ipconfig /all to display the IP configuration of PC1. You should see that PC1 has an incorrect IP address of 192.168.2.10, which belongs to VLAN 2 instead of VLAN 1. Enter the command ping 192.168.1.1 to test the connectivity to Core Switch 1. You should see that PC1 is unable to ping Core Switch 1 because they are on different subnets. Enter the command tracert 192.168.1.1 to trace the route to Core Switch 1. You should see that PC1 is unable to reach Core Switch 1 because there is no route between them.

  You can use the same steps to enter commands in other devices, such as PC3, PC4, PC5, and Server 1.

• Question 383:

  Which of the following does the IP address 169.254.222.10 indicate?

  A. No DHCP server connectivity
  B. The DNS server is unavailable
  C. Firewall issue
  D. Duplicate IP addresses are found
  A. No DHCP server connectivity

• Question 384:

  Which of the following would MOST likely be used to review disaster recovery information for a system?

  A. Business continuity plan
  B. Change management
  C. System life cycle
  D. Standard operating procedures
  A. Business continuity plan

• Question 385:

  A business purchased redundant internet connectivity from two separate ISPs. Which of the following is the business MOST likely implementing?

  A. NIC teaming
  B. Hot site
  C. Multipathing
  D. Load balancing
  C. Multipathing

  ---

  Explanation/Reference:

  Multipathing is a technique that allows a device to use more than one path to communicate with another device. This provides redundancy, load balancing, and fault tolerance for network connections. A business that purchased redundant internet connectivity from two separate ISPs is most likely implementing multipathing to ensure continuous access to the internet in case one ISP fails or becomes congested.

• Question 386:

  A network administrator is required to ensure that auditors have read-only access to the system logs, while systems administrators have read and write access to the system logs, and operators have no access to the system logs. The network administrator has configured security groups for each of these functional categories. Which of the following security capabilities will allow the network administrator to maintain these permissions with the LEAST administrative effort?

  A. Mandatory access control
  B. User-based permissions
  C. Role-based access
  D. Least privilege
  C. Role-based access

  ---

  Explanation/Reference:

  Role-based access is a security capability that assigns permissions to users based on their roles or functions within an organization. It allows the network administrator to maintain these permissions with the least administrative effort, as they only need to configure the security groups for each role once and then assign users to those groups. Mandatory access control is a security capability that assigns permissions based on security labels or classifications, which requires more administrative effort to maintain. User-based permissions are a security capability that assigns permissions to individual users, which is not scalable or efficient for large organizations. Least privilege is a security principle that states that users should only have the minimum level of access required to perform their tasks, which is not a security capability by itself.

• Question 387:

  Which of the following routing protocols is BEST suited for use on a perimeter router?

  A. OSPF
  B. RIPv2
  C. EIGRP
  D. BGP
  D. BGP

  ---

  Explanation/Reference:

  BGP is a path vector routing protocol that is designed for use between different autonomous systems (ASes) on the internet. It is commonly used for inter-domain routing, making it well-suited for perimeter routers that connect to external networks and ISPs. BGP allows the router to exchange routing information and make routing decisions based on policies, route preferences, and path attributes. It provides granular control over routing decisions and is particularly suited for large-scale networks with complex routing requirements.

• Question 388:

  A technician is assisting a user who cannot connect to a network resource. The technician first checks for a link light. According to troubleshooting methodology, this is an example of:

  A. using a bottom-to-top approach.
  B. establishing a plan of action.
  C. documenting a finding.
  D. questioning the obvious.
  A. using a bottom-to-top approach.

• Question 389:

  A switch is connected to another switch. Incompatible hardware causes a surge in traffic on both switches. Which of the following configurations will cause traffic to pause, allowing the switches to drain buffers?

  A. Speed
  B. Flow control
  C. 802.1Q
  D. Duplex
  B. Flow control

  ---

  Explanation/Reference:

  Flow control is a mechanism that allows a network device to regulate the amount of traffic it can receive or send. Flow control can help prevent congestion and buffer overflow by sending pause frames or signals to the sender when the receiver's buffer is full or nearly full. Flow control can cause traffic to pause, allowing the switches to drain buffers and resume normal operation. Speed is a parameter that determines the data transfer rate of a network link. 802.1Q is a standard for VLAN (Virtual Local Area Network) tagging, which allows multiple logical networks to share the same physical infrastructure. Duplex is a mode of communication that determines how data is transmitted and received on a link. Full duplex allows simultaneous transmission and reception, while half duplex allows only one direction at a time.

  Which of the following is the LARGEST MTU for a standard Ethernet frame?

  A. 1452
  B. 1492
  C. 1500
  D. 2304
  C. 1500

  ---

  Explanation/Reference:

  The largest MTU (Maximum Transmission Unit) for a standard Ethernet frame is 1500 bytes.
