CompTIA N10-006 Online Questions & Answers

• Question 1111:

  An administrator needs to open ports in the firewall for both DNS and eDNS. Which of the following default ports would need to be opened on the firewall? (Select TWO).

  A. TCP 23
  B. TCP 53
  C. TCP 123
  D. UDP 23
  E. UDP 53
  F. UDP 123
  B. TCP 53
  E. UDP 53

• Question 1112:

  A technician is connecting a NAS device to an Ethernet network. Which of the following technologies will be used to encapsulate the frames?

  A. HTTPS
  B. Fibre channel
  C. iSCSI
  D. MS-CHAP
  C. iSCSI

  ---

  A NAS or a SAN will use either iSCSI or Fiber Channel. In this question, the NAS is connected to an Ethernet network. Therefore, iSCSI will most likely be used (Fiber Channel over Ethernet (FCoE) can be used but is less common). ISCSI means Internet SCSI. ISCSI uses TCP (Transmission Control Protocol) which enables it to be used over TCP/IP networks such as Ethernet. For Fiber channel,a separate Fiber Channel network would be required unless FCoE is used.

• Question 1113:

  An administrator has a virtualization environment that includes a vSAN and iSCSI switching. Which of the following actions could the administrator take to improve the performance of data transfers over iSCSI switches?

  A. The administrator should configure the switch ports to auto-negotiate the proper Ethernet settings.
  B. The administrator should configure each vSAN participant to have its own VLAN.
  C. The administrator should connect the iSCSI switches to each other over inter-switch links (ISL).
  D. The administrator should set the MTU to 9000 on the each of the participants in the vSAN.
  D. The administrator should set the MTU to 9000 on the each of the participants in the vSAN.

  When using an iSCSI SAN (with iSCSI switching), we can improve network performance by enabling `jumbo frames'. A jumbo frame is a frame with an MTU of more than 1500. By setting the MTU to 9000, there will be fewer but larger frames going over the network. Enabling jumbo frames can improve network performance by making data transmissions more efficient. The CPUs on switches and routers can only processone frame at a time. By putting a larger payload into each frame, the CPUs have fewer frames to process.

• Question 1114:

  Due to a recent change in company policy, all users managing network infrastructure devices must use SSH v2 and all administrative activity must be collected on a central store. Which of the following should the network administrator deploy to comply with the new collection requirements?

  A. Network intrusion detection
  B. Traffic analysis tool
  C. Syslog server
  D. Network sniffer
  C. Syslog server

• Question 1115:

  When network administrators observe an increased amount of web traffic without an increased number of financial transactions, the company is MOST likely experiencing which of the following attacks?

  A. Bluejacking
  B. ARP cache poisoning
  C. Phishing
  D. DoS
  D. DoS

• Question 1116:

  During a disaster recovery test, several billing representatives need to be temporarily setup to take payments from customers. It has been determined that this will need to occur over a wireless network, with security being enforced where possible. Which of the following configurations should be used in this scenario?

  A. WPA2, SSID enabled, and 802.11n.
  B. WEP, SSID enabled, and 802.11b.
  C. WEP, SSID disabled, and 802.11g.
  D. WPA2, SSID disabled, and 802.11a.
  D. WPA2, SSID disabled, and 802.11a.

  Explanation Explanation/Reference:WPA2 is a security technology commonly used on Wi-Fi wireless networks. WPA2 (Wireless Protected Access 2) replaced the original WPA technology on all certified Wi-Fi hardware since 2006 and is based on the IEEE 802.11i technology standard for data encryption.

• Question 1117:

  A technician is setting up a firewall on the network that would show a public IP address out to the Internet and assign private IP addresses to users inside the network. Which of the following processes should be set up?

  A. Port security
  B. MAC filtering
  C. ACL
  D. NAT
  D. NAT

• Question 1118:

  Joe has a small office and is looking to replace his phone system with a lower cost solution that requires minimal in-house support. Which of the following is the BEST choice?

  A. Wide Area Network
  B. NAT
  C. Virtual PBX
  D. Virtual LAN
  C. Virtual PBX

  ---

  Virtual PBX, a business phone system providing call routing, follow-me calling, voice-mail, fax- mail, and ACD queues with no customer installed equipment.

• Question 1119:

  A company is connected to an ISP, but owns the premise router with an internal CSU/DSU. Which of the following is considered the demarc?

  A. Premise router
  B. ISP router
  C. Smart jack
  D. CSU/DSU
  C. Smart jack

• Question 1120:

  C. Deny port 20
  D. Deny port 80
  E. Allow port 23
  A. Allow port 443
  D. Deny port 80
