CompTIA N10-009 Online Questions & Answers

• Question 491:

  Which of the following is most likely responsible for the security and handling of personal data in Europe?

  A. GDPR
  B. SCADA
  C. SAML
  D. PCI DSS
  A. GDPR

• Question 492:

  Which of the following should be used to obtain remote access to a network appliance that has failed to start up properly?

  A. Crash cart
  B. Jump box
  C. Secure Shell (SSH)
  D. Out-of-band management
  D. Out-of-band management

  ---

  Explanation

  If a network appliance fails to start, standard remote access methods like SSH won't work. Instead, Out-of-Band (OOB) management provides a dedicated access path (e.g., a console port iDRAC/iLO or ), allowing administrators to troubleshoot devices even when the network is down.

  Breakdown of Options:

  Option A. Crash cart - A physical monitor/keyboard setup not a remote solution,.

  Option B. Jump box - A hardened system used for secure remote access but requires the device to be operational.

  Option C. Secure Shell (SSH) - Requires the device to be fully booted and network-connected.

  Option D. Out-of-band management - Correct answer. Provides independent access for troubleshooting failed network devices.

• Question 493:

  A global company has acquired a local company. The companies are geographically separate. The IP address ranges for the two companies are as follows:

  Global company: 10.0.0.0/16

  Local company: 10.0.0.0/24

  Which of the following can the network engineer do to quickly connect the two companies?

  A. Assign static routing to advertise the local company's network.
  B. Assign an overlapping IP address range to both companies.
  C. Assign a new IP address range to the local company.
  D. Assign a NAT range to the local company.
  C. Assign a new IP address range to the local company.

  ---

  Explanation

  Assigning a new IP address range to the local company is the best option to quickly connect the two companies without causing any IP address conflicts or overlaps. This option requires reconfiguring the local company's network devices and updating the routing tables on both sides, but it avoids the need for any NAT or static routing solutions that may introduce additional complexity, cost, or performance issues.

• Question 494:

  A company wants to implement a disaster recovery site or non-critical applicance, which can tolerance a short period of downltime.

  Which of the followig type of sites should the company impelement to achive this goal?

  A. Hot
  B. Cold
  C. Warm
  D. Passive
  C. Warm

  ---

  Explanation

  A warm site is a compromise between a hot site and a cold site, providing a balance between cost and recovery time. It is partially equipped with the necessary hardware, software, and infrastructure, allowing for a quicker recovery compared to a cold site but at a lower cost than a hot site.

  Recovery Time: Warm sites can be operational within hours to a day, making them suitable for non-critical applications that can tolerate short downtimes.

  Cost-Effectiveness: Warm sites are more economical than hot sites as they do not require all systems to be fully operational at all times.

  + Certification All-in-One Exam Guide: Explains the characteristics of hot, warm, and cold sites and their use cases in disaster recovery planning. Warm sites offer a practical solution for maintaining business continuity for non-critical applications, balancing the need for availability with cost considerations.

• Question 495:

  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?

  A. SOA
  B. MX
  C. CNAME
  D. NS
  C. CNAME

  ---

  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 as www.comptia.org by creating a CNAME record pointing newapplication.comptia.org to www.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.

  References:

  The DNS section of the CompTIA Network+ materials describes the use of CNAME records for creating domain aliases.

• Question 496:

  Which of the following is used to store and deliver content to clients in a geographically distributed manner using edge servers?

  A. Load balancer
  B. CDN
  C. DNS server
  D. SAN
  B. CDN

• Question 497:

  Which of the following protocols is used to route traffic on the public internet?

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

  ---

  Explanation

  Border Gateway Protocol (BGP)is the primary protocol used to route traffic on the public internet. It allows ISPs and large networks to exchange routing information, making it an Exterior Gateway Protocol (EGP).

  Breakdown of Options:

  Option A. BGP - Correct answer. Used for internet routing and exchanges routing information between ISPs.

  Option B. OSPF - An Interior Gateway Protocol (IGP) used for routing within an autonomous system (not the public internet).

  Option C. EIGRP - Cisco's proprietary IGP, used within private networks, not the public internet.

  Option D. RIP - An older distance-vector protocol not scalable, for the internet.

• Question 498:

  A network administrator needs to set up a multicast network for audio and video broadcasting.

  Which of the following networks would be the most appropriate for this application?

  A. 172.16.0.0/24
  B. 192.168.0.0/24
  C. 224.0.0.0/24
  D. 240.0.0.0/24
  C. 224.0.0.0/24

• Question 499:

  A cloud service provider asks a company to verify domain ownership by adding a specific value into a DNS record.

  Which of the following DNS record types should be used?

  A. SOA
  B. SRV
  C. TXT
  D. AAAA
  C. TXT

• Question 500:

  After HVAC failures caused network outages, the support team decides to monitor the temperatures of all the devices. The network administrator cannot find a command that will display this information.

  Which of the following will retrieve the necessary information?

  A. SNMP OID values
  B. NetFlow data export
  C. Network baseline configurations
  D. Security information and event management
  A. SNMP OID values

  ---

  Explanation

  The network administrator can use the Simple Network Management Protocol (SNMP) to monitor the temperatures of all the devices. SNMP is a widely-used protocol for managing and monitoring network devices, such as routers, switches, servers, and other networking equipment. SNMP allows network administrators to gather information about the performance and status of devices on the network, including temperature readings. To retrieve the temperature information, the administrator will have to configure SNMP on the devices and configure SNMP manager software on their computer. Once the SNMP manager software is configured, it will be able to send SNMP requests to the devices and retrieve information such as temperature, voltage, fan speeds, etc. Many network devices have built-in SNMP support, and the administrator may also need to install SNMP agent software on the devices to enable SNMP monitoring. The administrator can also use some specific command or tool like IPMI (Intelligent Platform Management Interface) or DCIM (Data Center Infrastructure Management) tools for monitoring the temperatures of all the devices.
