CompTIA N10-009 Online Questions & Answers

• Question 741:

  Which of the following connection methods allows a network engineer to automate configuration deployment for network devices across the environment?

  A. RDP
  B. Telnet
  C. SSH
  D. GUI
  C. SSH

  ---

  Explanation

  SSH provides secure, scriptable remote access used by automation/orchestration tools (e.g., leveraging CLI, NETCONF over SSH, or Ansible modules) to push configurations at scale.

  Option A: RDP is primarily for Windows GUI sessions and is not commonly used for network device automation.

  Option B: Telnet can be scripted but is insecure (plaintext); modern best practice is to use SSH.

  Option D: GUI access is typically manual and not ideal for scalable, repeatable automation.

• Question 742:

  A company wants to centrally manage authentication and authorization for administrative access to network devices.

  Which protocol should be implemented?

  A. RADIUS
  B. TACACS+
  C. LDAP
  D. Kerberos
  B. TACACS+

• Question 743:

  Which of the following enables an organization to leverage an identity provider to manage access across SaaS applications?

  A. PKI
  B. SSO
  C. TACACS+
  D. RADIUS
  B. SSO

  ---

  Explanation

  SSO (Single Sign-On) enables users to authenticate once and access multiple applications through a centralized identity provider. PKI provides certificate-based security but does not manage SaaS access across multiple services. TACACS+ and RADIUS are AAA protocols primarily used for network device and access control, not SaaS federation. Therefore, SSO is correct.

• Question 744:

  A network administrator is planning to implement device monitoring to enhance network visibility. The security that the solution provies authentication and encryption.

  Which of the following meets these requirements?

  A. SIEM
  B. Syslog
  C. NetFlow
  D. SNMPv3
  D. SNMPv3

  ---

  Explanation

  SNMPv3 (Simple Network Management Protocol version 3) provides device monitoring with authentication and encryption. This enhances network visibility and security by ensuring that monitoring data is securely transmitted and access to network devices is authenticated.

  Authentication: SNMPv3 includes robust mechanisms for authenticating users accessing network devices.

  Encryption: It provides encryption to protect the integrity and confidentiality of the data being transmitted.

  Network Management: SNMPv3 allows for detailed monitoring and management of network devices, ensuring better control and security.

• Question 745:

  A network technician is configuring the company's network of 100 Mbps Layer 2 switches. The technician wants increased throughput for the uplinks between switches. The technician connects multiple redundant links between the switches.

  Which of the following should the technician configure?

  A. Spanning Tree Protocol
  B. Switch Virtual Interfaces
  C. Native VLAN
  D. First Hop Redundancy Protocol
  A. Spanning Tree Protocol

  ---

  Explanation

  When multiple redundant links exist between switches, Spanning Tree Protocol (STP) is required to prevent switching loops. STP blocks redundant paths but can allow aggregation if configured with protocols like LACP.

  Option B: SVIs provide Layer 3 interfaces, not loop prevention.

  Option C: Native VLAN defines the untagged VLAN but does not manage loops.

  Option D: FHRP (VRRP, HSRP, GLBP) provides gateway redundancy, not switch uplink management.

• Question 746:

  Which of the following allows devices within a network to share a reliable time source?

  A. NTP
  B. SNMP
  C. SIP
  D. DNS
  A. NTP
