What do the address resolution protocol (ARP) for IPv4 and the neighbor discovery procedures for IPv6 have in common?
- A . Both detect duplicate MAC address assignments.
- B . Both detect duplicate IP address assignments.
- C . Both resolve a host device’s MAC address using its IP address.
- D . Both resolve a host device’s IP address using its MAC address.
Which of the following statements about the IP forwarding process on a router is TRUE?
- A . It uses the routing table to find a match for the source IP address.
- B . It uses the routing table to find a match for the destination IP address.
- C . It uses the ARP table to find a match for the source MAC address.
- D . It uses the ARP table to find a match for the destination MAC address.
When multiple routing protocols offer a route for the same prefix, what part of the router is in charge of deciding which route to make active?
- A . The routing information base (RIB)
- B . The routing table manager (RTM)
- C . The equal cost multipath configuration
- D . The forwarding information base (FIB)
Refer to the exhibit.
All routers in the diagram are running an interior gateway protocol (IGP) and have been configured with an ECMP value of 4. Router R5 advertises the prefix 192.168.3.0/24 using the IGP.
Assuming all links have the same cost, how many entries for prefix 192.168.3.0/24 will be in router R3’s routing table?
- A . 1
- B . 2
- C . 3
- D . 4
Which component of the Nokia 7750 SR is in charge of performing the longest prefix match lookup on packets that arrive on the physical interfaces?
- A . Control Processing Module (CMP)
- B . Media Dependent Adapter (MDA)
- C . Switch Fabric (SF)
- D . Input/Output Module (IOM)
What is the replacement for ARP in IPv6?
- A . Duplicate address detection procedures.
- B . Router discovery procedures.
- C . Neighbor discovery procedures.
- D . Stateless address auto-configuration procedures.
Which of the following definitions best describes route redistribution?
- A . It is the process of deciding at line-rate speed which packets will be dropped and which ones will be forwarded.
- B . It is the process of redirecting packets to be processed by an intermediate network function before allowing them to be forwarded to their intended final destination.
- C . It is the process of passing routing information from one routing domain to another, which usually means from one routing protocol to another.
- D . It is the process of controlling which route advertisements received from routing peers are accepted and/or deciding which locally known prefixes are advertised to routing peers.
Which of the following is NOT a function of the control plane a router?
- A . To exchange signaling messages with other routers.
- B . To determine the best way to forward packets.
- C . To establish routing paths to deliver packets from source to destination and to reestablish them in case of failure.
- D . To utilize the forwarding tables to forward data packets towards their destination.
Which of the following is a valid alternative representation of the IPv6 address 2001:0da8:0000:0000:0024:0000:4ab9:0300?

- B . 2001:da8::0:24::4ab9:300
- C . 2001:da8::24::4ab9:300
- D . 2001:da8::24:0:4ab9:300
Which of the following statements about router interfaces on a Nokia 7750 SR is FALSE?
- A . They can be used in pairs on the same subnet for redundancy.
- B . They can be assigned IPv4 and/or IPv6 addresses.
- C . They can be logical or physical.
- D . The system interface exists by default.
