CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 311:

  A network administrator needs to change where the outside DNS records are hosted. Which of the following records should the administrator change at the registrar to accomplish this task?

  A. NS

  B. SOA

  C. PTR

  D. CNAME

  Correct Answer: A

  NS stands for Name Server, and it is a DNS record that specifies which servers are authoritative for a domain. The registrar is the entity that manages the domain registration and delegation, and it maintains the NS records for each domain. To change where the outside DNS records are hosted, the network administrator needs to change the NS records at the registrar to point to the new DNS servers that will host the outside DNS records.

• Question 312:

  A technician is trying to install a VolP phone, but the phone is not turning on. The technician checks the cable gong from the phone to the switch, and the cable is good. Which of the following actions IS needed for this phone to work?

  A. Add a POE injector

  B. Enable MDIX.

  C. Use a crossover cable.

  D. Reconfigure the port.

  Correct Answer: A

• Question 313:

  Which of the following technologies would MOST likely De used to prevent the loss of connection between a virtual server and network storage devices?

  A. Multipathing

  B. VRRP

  C. Port aggregation

  D. NIC teaming

  Correct Answer: D

  NIC teaming is a technology that allows multiple network interface cards (NICs) to work together as a single logical interface, providing redundancy and load balancing. This can prevent the loss of connection between a virtual server and network storage devices if one of the NICs fails or becomes disconnected.

• Question 314:

  An organization has experienced an increase in malicious spear-phishing campaigns and wants to mitigate the risk of hyperlinks from inbound emails.

  Which of the following appliances would best enable this capability?

  A. Email protection gateway

  B. DNS server

  C. Proxy server

  D. Endpoint email client

  E. Sandbox

  Correct Answer: A

  An email protection gateway is an appliance that can filter and block malicious emails and attachments before they reach the recipients. An email protection gateway can mitigate the risk of hyperlinks from inbound emails by scanning the links for malicious content, rewriting the links to point to a safe domain, or blocking the links altogether. An email protection gateway can also perform other functions such as spam filtering, antivirus scanning, encryption, and data loss prevention. A DNS server, a proxy server, an endpoint email client, and a sandbox are not appliances that can enable this capability, as they have different purposes and functions.

• Question 315:

  A network engineer needs to enable device monitoring using authentication and encryption. Which of the following protocols offers this option?

  A. ESP

  B. SNMPv3

  C. NetFIow

  D. SSLv3

  Correct Answer: B

  SNMPv3 is a protocol that offers device monitoring using authentication and encryption. SNMP stands for Simple Network Management Protocol, and it is a standard way of collecting and organizing information about network devices, such as routers, switches, servers, printers, and so on. SNMPv3 is the latest version of SNMP, and it provides enhanced security features, such as data integrity, data origin authentication, data confidentiality, and access control. SNMPv3 can use different algorithms to encrypt and authenticate the communication between the network management system and the network devices12.

• Question 316:

  Which of the following network types is composed of computers that can all communicate with one another with equal permissions and allows users to directly share what is on or attached to their computers?

  A. Local area network

  B. Peer-to-peer network

  C. Client-server network

  D. Personal area network

  Correct Answer: B

  A peer-to-peer network is a type of network in which each computer (or node) can communicate directly with any other node, without requiring a central server or authority. Each node can act as both a client and a server, and can share its own resources, such as files, printers, or internet connection, with other nodes. A peer-to-peer network allows users to directly access and exchange what is on or attached to their computers, with equal permissions and responsibilities

• Question 317:

  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

  Correct Answer: C

  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 318:

  A senior administrator has been directed to incorporate AAA services within a domain environment for regulatory compliance purposes. Which of the following standards will enable the use of an AAA server in a domain environment?

  A. 802.1Q

  B. 802.1X

  C. 802.3bt

  D. 802.11h

  Correct Answer: B

  802.1X is a standard that enables the use of an AAA server in a domain environment by providing port-based network access control. 802.1X authenticates users or devices before granting them access to the network resources, and can also authorize them based on their roles or policies. 802.1X can work with different AAA protocols, such as RADIUS or TACACS+, to communicate with the AAA server.

• Question 319:

  A Fortune 500 firm is deciding On the kind or data center equipment to install given its five- year budget Outlook. The Chief Information comparing equipment based on the life expectancy Of different models. Which of the following concepts BEST represents this metric?

  A. MTBF

  B. MTRR

  C. RPO

  D. RTO

  Correct Answer: A

• Question 320:

  A network administrator needs to implement a solution to mediate access to the internet- Which of the following should the administrator most likely implement?

  A. Router

  B. Cloud gateway

  C. proxy

  D. Intrusion prevention system

  Correct Answer: C

  A proxy is a solution that can mediate access to the internet. A proxy is a server that acts as an intermediary between a client and a destination server on the internet. A proxy can perform various functions, such as filtering, caching, logging, or modifying requests and responses. A proxy can help improve network performance, security, and privacy by reducing bandwidth consumption, blocking malicious or unwanted content, monitoring network activity, and hiding the client's identity or location.
