• Question 666:

  DRAG DROP

  Drag and drop the addresses from the left onto the correct IPv6 filter purposes on the right.

  Select and Place:

  

  Correct Answer:

  

  HTTP and HTTPs run on TCP port 80 and 443, respectively and we have to remember them.

  Syslog runs on UDP port 514 while NTP runs on UDP port 123 so if we remember them we can find out the matching answers easily.

  But maybe there is some typos in this question as 2001:d88:800:200c::c/126 only ranges from 2001:d88:800:200c:0:0:0:c to 2001:d88:800:200c:0:0:0:f (4 hosts in total).

  It does not cover host 2001:0D88:0800:200c::1f. Same for 2001:D88:800:200c::e/126, which also ranges from 2001:d88:800:200c:0:0:0:c to 2001:d88:800:200c:0:0:0:f and does not cover host 2001:0D88:0800:200c::1c.

• Question 667:

  DRAG DROP

  Drag and drop the DHCP messages from the left onto the correct uses on the right.

  Select and Place:

  

  Correct Answer:

  

  +

  server-to-client communication, refusing the request for configuration parameters: DHCPNAK

  +

  client-to-server communication, indicating that the network address is already in use: DHCPDECLINE

  +

  server-to-client communication with configuration parameters, including committed network address: DHCPACK

  +

  client-to-server communication, asking for only local configuration parameters that the client has already externally configured as an address: DHCPINFORM

  DHCPINFORM: If a client has obtained a network address through some other means or has a manually configured IP address, a client workstation may use a DHCPINFORM request message to obtain other local configuration parameters, such as the domain name and Domain Name Servers (DNSs). DHCP servers receiving a DHCPINFORM message construct a DHCPACK message with any local configuration parameters appropriate for the client without allocating a new IP address. This DHCPACK will be sent unicast to the client.

  DHCPNAK: If the selected server is unable to satisfy the DHCPREQUEST message, the DHCP server will respond with a DHCPNAK message. When the client receives a DHCPNAK message, or does not receive a response to a DHCPREQUEST message, the client restarts the configuration process by going into the Requesting state. The client will retransmit the DHCPREQUEST at least four times within 60 seconds before restarting the Initializing state.

  DHCPACK: After the DHCP server receives the DHCPREQUEST, it acknowledges the request with a DHCPACK message, thus completing the initialization process. DHCPDECLINE: The client receives the DHCPACK and will optionally perform a final check on the parameters. The client performs this procedure by sending Address Resolution Protocol (ARP) requests for the IP address provided in the DHCPACK. If the client detects that the address is already in use by receiving a reply to the ARP request, the client will send a DHCPDECLINE message to the server and restart the configuration process by going into the Requesting state.

  Correct Answer:

  

  Implicit null Label : LSR receives an MPLS header with the label set to 3 Ref :https://www.ciscopress.com/articles/article.asp?p=680824andseqNum=2 Explicit Null Label : packet is encapsulated in MPLS with the option of copying the IP precedence to EXP bit

  [Ref: https://www.ciscopress.com/articles/article.asp?p=680824andseqNum=2 ]

  Inbound Label Binding Filtering : Controls the amount of memory used to store Label Distribution Protocol (LDP) label bindings advertised by other devices.
