CompTIA N10-005 Online Questions & Answers

• Question 811:

  Which of the following is the common port used for IMAP?

  A. 25
  B. 53
  C. 143
  D. 443
  C. 143

  ---

  The Internet Message Access Protocol (commonly known as IMAP) is an Application Layer Internet protocol that allows an e-mail client to access e-mail on a remote mail server. The current version, IMAP version 4 revision 1 (IMAP4rev1), is defined by RFC 3501. An IMAP server typically listens on well-known port 143

• Question 812:

  A technician is installing a switch that will be used for VoIP and data traffic. The phones do not support the 802.3af standard. Which of the following should the technician configure on the switch?

  A. VLAN
  B. PoE
  C. VTP
  D. QoS
  D. QoS

• Question 813:

  A technician is setting up a wireless access point and wants to keep it as secure as possible. Which of the following settings should be configured for security purposes? (Select TWO).

  A. Channel
  B. Encryption
  C. Diversity
  D. SSID broadcast
  E. Frequency
  B. Encryption
  D. SSID broadcast

• Question 814:

  A network administrator is responding to a statement of direction made by senior management to implement network protection that will inspect packets as they enter the network. Which of the following technologies would be used?

  A. Packet sniffer
  B. Stateless firewall
  C. Packet filter
  D. Stateful firewall
  D. Stateful firewall

  ---

  Stateful firewall keeps track of the state of network connections (such as TCP streams, UDP communication) traveling across it. The firewall is programmed to distinguish legitimate packets for different types of connections. Only packets matching a known active connection will be allowed by the firewall; others will be rejected.

• Question 815:

  Some visitors are unable to access the wireless network. The network's wireless infrastructure is comprised of three different buildings with the configurations listed below. Wireless network in Building A and C is used exclusively for internal employees and Building B is used for visitors and requires no additional configuration on their devices.

  Which of the following settings would need to be modified to provide wireless access to all visitors?

  Building A Building B Building C Channel: 2 Channel: 6 Channel: 11 Encryption: WPA2 Encryption: WPA2 Encryption: WPA2

  A. Encryption set to Open in all Buildings
  B. Encryption set to Open in Building B
  C. Encryption set to WEP in Building B
  D. Channel set to 11 in Building B
  B. Encryption set to Open in Building B

  ---

  Because the building B is in the middle, the wireless access router will have reachability to the building A and C. Now, the only thing that we need to do is to open the Wireless access on B for the guest users for the WAP in B so that the users coming to building A and C can get access to internet using the open connection.

• Question 816:

  Which of the following wireless technologies only uses the 5GHz spectrum but reaches a theoretical throughput of only 54Mbps?

  A. A
  B. B
  C. G
  D. N
  A. A

  ---

  802.11a standard uses the same core protocol as the original standard, operates in 5 GHz band, and uses a 52-subcarrier orthogonal frequency-division multiplexing (OFDM) with a maximum raw data rate of 54 Mbit/s, which yields realistic net achievable throughput in the mid-20 Mbit/s. The data rate is reduced to 48, 36, 24, 18, 12, 9 then 6 Mbit/s if required.

• Question 817:

  A user is unable to connect to a remote computer using RDP. The technician checks the firewall rules and notes that there is no rule that blocks RDP. Which of the following features of the firewall is responsible for blocking RDP?

  A. Stateful inspection
  B. NAT/PAT
  C. Port security
  D. Implicit deny
  D. Implicit deny

• Question 818:

  Which of the following does Kerberos use to authenticate?

  A. Tickets
  B. Servers
  C. Users
  D. Clients
  A. Tickets

  ---

  Kerberos keeps a database of its clients and their private keys. The private key is a large number known only to Kerberos and the client it belongs to. In the case that the client is a user, it is an encrypted password. Network services requiring

  authentication register with Kerberos, as do clients wishing to use those services.

  The private keys are negotiated at registration.

• Question 819:

  An IP camera has a failed PoE NIC. This is the third time in months that a PoE NIC has failed on this device. The technician suspects a possible power issue. Which of the following should be used to test the theory?

  A. Toner probe
  B. Loopback plug
  C. Protocol analyzer
  D. Multimeter
  D. Multimeter

• Question 820:

  When implementing video streaming from the Internet to an always on device, it is best to employ which of the following services to minimize latency issues?

  A. QoS
  B. EIGRP
  C. PPTP
  D. OSPF
  A. QoS
