CompTIA Network Recertification Exam for Continuing Education

Question No: 1 – (Topic 1)

Which of the following protocols uses label-switching routers and label-edge routers to forward traffic?

  1. BGP

  2. OSPF

  3. IS-IS

  4. MPLS

Answer: D Explanation:

In an MPLS network, data packets are assigned labels. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. MPLS works by prefixing packets with an MPLS header, containing one or more labels.

An MPLS router that performs routing based only on the label is called a label switch router (LSR) or transit router. This is a type of router located in the middle of a MPLS network. It is responsible for switching the labels used to route packets. When an LSR receives a packet, it uses the label included in the packet header as an index to determine the next hop on the label-switched path (LSP) and a corresponding label for the packet from a lookup table. The old label is then removed from the header and replaced with the new label before the packet is routed forward.

A label edge router (LER) is a router that operates at the edge of an MPLS network and acts as the entry and exit points for the network. LERs respectively, add an MPLS label onto an incoming packet and remove it off the outgoing packet.

When forwarding IP datagrams into the MPLS domain, an LER uses routing information to determine appropriate labels to be affixed, labels the packet accordingly, and then forwards the labelled packets into the MPLS domain. Likewise, upon receiving a labelled packet which is destined to exit the MPLS domain, the LER strips off the label and forwards the

resulting IP packet using normal IP forwarding rules.

Question No: 2 – (Topic 1)

Which of the following refers to a network that spans several buildings that are within walking distance of each other?

  1. CAN

  2. WAN

  3. PAN

  4. MAN

Answer: A Explanation:

CAN stands for Campus Area Network or Corporate Area Network. Universities or colleges often implement CANs to link the buildings in a network. The range of CAN is 1KMto 5KM. If multiple buildings have the same domain and they are connected with a network, then it will be considered as a CAN.

Question No: 3 – (Topic 1)

A technician, Joe, needs to troubleshoot a recently installed NIC. He decides to ping the local loopback address. Which of the following is a valid IPv4 loopback address?

A. 10.0.0.1

B. 127.0.0.1

C. 172.16.1.1

D. 192.168.1.1

Answer: B Explanation:

The loopback address is a special IP address that is designated for the software loopback interface of a computer. The loopback interface has no hardware associated with it, and it is not physically connected to a network. The loopback address causes any messages sent to it to be returned to the sending system. The loopback address allows client software to communicate with server software on the same computer. Users specify the loopback address which willpoint back to the computer#39;s TCP/IP network configuration.

In IPv4, the loopback address is 127.0.0.1.

In IPv6, the loopback address is 0:0:0:0:0:0:0:1, more commonly notated as follows. ::1

A Cable Certifier provides “Pass” or “Fail” information in accordance with industry standards but can also show detailed information when a “Fail” occurs. This includesshorts, the wire pairs involved and the distance to the short. When a short is identified, at the full length of the cable it means the cable has not been crimped correctly.

Question No: 5 – (Topic 1)

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

  1. All routers are using hop count as the metric

  2. Allrouters have the same routing table

  3. All routers learn the route to all connected networks

  4. All routers use route summarization

Answer: C Explanation:

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 quot;agreequot; on what the network topology looks like.

Question No: 6 – (Topic 1)

Which of the following is MOST likely to use an RJ-11 connector to connect a computer to an ISP using a POTS line?

  1. Multilayer switch

  2. Access point

  3. Analog modem

  4. DOCSIS modem

Answer: C Explanation:

Before ADSL broadband connections became the standard for Internet connections, computers used analog modems to connect to the Internet. By today’s standards, analog modems are very slow typically offering a maximum bandwidth of 56Kbps.

An analog modem (modulator/demodulator) converts (modulates) a digital signal from a computerto an analog signal to be transmitted over a standard (POTS) phone line. The modem then converts (demodulates) the incoming analog signal to digital data to be used by the computer.

An analog modem uses an RJ-11 connector to connect to a phone line (POTS)in the same way a phone does.

Question No: 7 – (Topic 1)

Joe, a network technician, is setting up a DHCP server on a LAN segment. Which of the following options should Joe configure in the DHCP scope, in order to allow hosts on that LAN segment using dynamic IP addresses, to be able to access the Internet and internal company servers? (Select THREE).

  1. Default gateway

  2. Subnet mask

  3. Reservations

  4. TFTP server

  5. Lease expiration time of 1 day

  6. DNS servers

  7. Bootp

Answer: A,B,F Explanation:

The question statesthat the client computers need to access the Internet as well as internal company servers. To access the Internet, the client computers need to be configured with an IP address with a subnet mask (answer B) and the address of the router that connects thecompany network to the Internet. This is known as the ‘default gateway’ (answer A).

To be able to resolve web page URLs to web server IP addresses, the client computers need to be configured with the address of a DNS server (answer F).

Question No: 8 – (Topic 1)

A technician just completed a new external website and setup access rules in the firewall. After some testing, only users outside the internal network can reach the site. The website responds to a ping from the internal network and resolves the proper public address. Which of the following could the technician do to fix this issue while causing internal users to route to the website using an internal address?

  1. Configure NAT on the firewall

  2. Implement a split horizon DNS

  3. Place the server in the DMZ

  4. Adjust the proper internal ACL

Answer: B Explanation:

Split horizon DNS (also known as Split Brain DNS) is a mechanism for DNS servers to supply different DNS query results depending on the source of the request. This can be done by hardware-basedseparation but is most commonly done in software.

In this question, we want external users to be able to access the website by using a public

IP address. To do this, we would have an external facing DNS server hosting a DNS zone for the website domain. Forthe internal users, we would have an internal facing DNS server hosting a DNS zone for the website domain. The external DNS zone will resolve the website URL to an external public IP address. The internal DNS server will resolve the website URL to an internal private IP address.

Question No: 9 – (Topic 1)

Which of the following would be used in an IP-based video conferencing deployment? (Select TWO).

  1. RS-232

  2. 56k modem

  3. Bluetooth

  4. Codec

  5. SIP

Answer: D,E Explanation:

The term quot;codecquot; is a concatenation of quot;encoderquot; and quot;decoder”. In video conferencing, a codec is software (or can be hardware) that compresses (encodes) raw video data before it is transmitted overthe network. A codec on the receiving video conferencing device will then decompress (decode) the video signal for display on the conferencing display.

The Session Initiation Protocol (SIP) is a protocol for initiating an interactive user session that involves multimedia elements such as voice, chat, gaming, or in this case video.
