Drag and drop the MPLS concepts from the left onto the descriptions on the right.
正解:
Explanation:
+ allows an LSR to remove the label before forwarding the packet: penultimate hop popping
+ accepts unlabeled packets and imposes labels: label edge router
+ group of packets that are forwarded in the same manner: forwarding equivalence class
+ receives labeled packets and swaps labels: label switch router
Explanation:
A label edge router (LER, also known as edge LSR) is a router that operates at the edge of an MPLS network and acts as the entry and exit points for the network. LERspush an MPLS label onto an incoming packet and pop it off an outgoing packet.
A forwarding equivalence class (FEC) is a term
A network administrator performed a Compact Flash Memory upgrade on a Cisco Catalyst 6509 Switch.

Refer to the exhibit.
A customer reports that user traffic of bank XYZ to the AAA server is not using the primary path via the R3-R2 link. The network team observes:
No fiber is cut on links R2 and R3.
As101 and AS 201 routers established BGP peering.

An engineer configured a leak-map command to summarize EIGRP routes and advertise specifically loopback
0 with an IP of 10.1.1.1.255.255.255.252 along with the summary route. After finishing configuration, the customer complained not receiving summary route with specific loopback address. Which two configurations will fix it? (Choose two.)

Drag and drop the DHCP messages from the left onto the correct uses on the right.
正解:
Explanation:
DHCPACK
The server-to-client communication with configuration parameters, including committed network address.
DHCPINFORM
The client-to-server communication, asking for only local configuration parameters that the client already has externally configured as an address.
DHCPNAK
The server-to-client communication, refusing the request for configuration parameter.
DHCPDECLINE
The client-to-server communication, indicating that the network address is already in use Reference:
https://www.cisco.com/c/en/us/support/docs/ip/dynamic-address-allocation-resolution/27470-100.html 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.
