Question 20
Which two network actions occur within the data plane? (Choose two) 
A. Add or remove an 802.1Q trunking header. 
B. Make a configuration change from an incoming NETCONF RPC. 
C. Run routing protocols. 
D. Reply to an incoming ICMP echo request. 
E. Match the destination MAC address to the MAC address table. 
Answer:
A E 
Explanation
For perspective, the following list details some of the more common actions that a networking 
device does that fit into the data plane: 
+ De-encapsulating and re-encapsulating a packet in a data-link frame (routers, Layer 3 
switches) 
+ 
Adding or removing an 802.1Q trunking header
(routers and switches) 
+ 
Matching an Ethernet frame’s destination Media Access Control (MAC) address to the 
MAC address table
(Layer 2 switches) 
+ Matching an IP packet’s destination IP address to the IP routing table (routers, Layer 3 
switches) 
+ Encrypting the data and adding a new IP header (for virtual private network [VPN] processing) 
+ Changing the source or destination IP address (for Network Address Translation [NAT] 
processing) 
+ Discarding a message due to a filter (access control lists [ACLs], port security)

An engineer assumes a configuration task from a peer. Router A must establish an OSPF 
neighbor relationship with neighbor 172.1.1.1. The output displays the status of the adjacency 
after 2 hours. What is the next step in the configuration process for the routers to establish an 
adjacency? 
A. Set the router B OSPF ID to the same value as its IP address 
B. Set the router B OSPF ID to a nonhost address 
C. Configure a point-to-point link between router A and router B 
D. Configure router A to use the same MTU size as router B
