CompTIA N10-006 Online Questions & Answers

• Question 261:

  A network technician is configuring a wireless network. To avoid interference from other wireless networks in the area, the technician should change which setting?

  A. Channel
  B. SSID
  C. Firewall rule
  D. Encryption
  A. Channel

• Question 262:

  A network administrator needs to configure a port on the switch that will enable all packets on a particular switch to be monitored. Which of the following would BEST complete this objective?

  A. Traffic shaping
  B. MAC filtering
  C. Port mirroring
  D. VLAN trunking
  C. Port mirroring

• Question 263:

  A network administrator is using a packet analyzer to determine an issue on the local LAN. Two separate computers are showing an error message on the screen and are unable to communicate with other computers in the same lab. The network administrator looks at the following output:

  SRC MACSRC IPDST MACDST IP

  00:1D:1F:AB:10:7D192.168.1.10:200015:BE:9F:AB:10:1D192.168.1.14:1200

  05:DD:1F:AB:10:27192.168.1.10:100022:C7:2F:AB:10:A2192.168.1.15:1300

  Given that all the computers in the lab are directly connected to the same switch, and are not using any virtualization technology, at which of the following layers of the OSI model is the problem occurring?

  A. Network
  B. Application
  C. Data link
  D. Transport
  A. Network

  ---

  If we look at the Source Mac column, we can see two different MAC addresses. Everynetwork interface card has a unique MAC address. These are the network cards in the two separate computers. If we look in the Source IP column, we can see that the two network cards have been assigned the same IP address (192.168.1.10). This is the problem in this question. The error message on the screens will be saying that "An IP conflict exists". Every network card connected to the network needs to be configured with a different IP address. As the problem is with the IP address configuration of the twocomputers, we know that the problem is occurring at the Network layer (layer 3) of the OSI model. The network layer is responsible for Internet Protocol (IP) addressing and routing.

• Question 264:

  A network security engineer is installing a new firewall to protect a single server that requires isolation from the majority of network resources. The server will require secure network access. Which of the following hardening steps should the engineer perform on the new firewall?

  A. Drop inbound and outbound traffic on ports 20,21,23, and 53. Allow inbound and outbound SSH traffic.Block outbound traffic on port 80.
  B. Block all ephemeral port numbers and UDP traffic at the firewall. Explicitly allow SSH traffic. Remove implicit deny statements for ports 53 and lower.
  C. Explicitly allow traffic on ports 22 and 443. Explicitly deny all other traffic at the firewall internal and external interfaces.
  D. Ensure the firewall OS is the latest version with all patches applied. Block traffic not seen in audit logs after a 48-hour test.
  C. Explicitly allow traffic on ports 22 and 443. Explicitly deny all other traffic at the firewall internal and external interfaces.

• Question 265:

  Users have reported choppy audio in phone conversations since the implementation of SIP phones on the network. Which of the following should be implemented to alleviate the delays?

  A. Caching
  B. VoIP
  C. QoS
  D. SMTP
  C. QoS

  ---

  Explanation Explanation/Reference:By Qos we can prioritize the voice packets over data network.So delay and latency will get reduce.

• Question 266:

  A PC is having trouble connecting to a remote resource.

  Which of the following will identify the routers a packet travels through and provide real-time feedback regarding latency?

  A. tracert
  B. NETBIOS
  C. ipconfig
  D. nslookup
  E. ping
  A. tracert

• Question 267:

  In order to discover the currently unknown IP address of the next-hop router, a network administrator would begin by using which of the following tools?

  A. NMAP
  B. ping
  C. nslookup
  D. tracert
  D. tracert

• Question 268:

  A server that filters traffic between a WAN and a LAN is which of the following?

  A. Proxy server
  B. RAS server
  C. Default gateway
  D. Email server
  A. Proxy server

• Question 269:

  An outside organization has completed a penetration test for a company. One of the items on the report is reflecting the ability to read SSL traffic from the web server. Which of the following is the MOST likely mitigation for this reported item?

  A. Ensure patches are deployed
  B. Install an IDS on the network
  C. Configure the firewall to block traffic on port 443
  D. Implement a VPN for employees
  A. Ensure patches are deployed

  ---

  As vulnerabilities are discovered, the vendors of the operating systems or applications often respond by releasing a patch.A patch is designed to correct a known bug or fix a known vulnerability, such as in this case to be able to read SSL traffic, in a piece of software. A patch differs from an update, which, in addition to fixing a known bug or vulnerability, adds one or more features to the software being updated.

• Question 270:

  When convergence on a routed network occurs, which of the following is true?

  A. All routers are using hop count as the metric
  B. Allrouters have the same routing table
  C. All routers learn the route to all connected networks
  D. All routers use route summarization
  C. All routers learn the route to all connected networks

  ---

  Routers exchange routing topology information with each other by using a routing protocol. Whenall routers have exchanged routing information with all other routers within a network, the routers are said to have converged. In other words: In a converged network all routers "agree" on what the network topology looks like.
