Which of the following must be true for a static route to be installed in a router’s IP routing table?
- A.
The outgoing interface associated with the route must be in an “up and up” state.
- B.
The router must receive a routing update from a neighboring router.
- C.
The ip route command must be added to the configuration.
- D.
The outgoing interface’s ip address command must use the special keyword.
Correct Answer(s)
A. The outgoing interface associated with the route must be in an “up and up” state.
C. The ip route command must be added to the configuration.Explanation
For a static route to be installed in a router's IP routing table, two conditions must be true. Firstly, the outgoing interface associated with the route must be in an "up and up" state, meaning it is operational and functioning properly. Secondly, the "ip route" command must be added to the router's configuration, specifying the destination network and the next hop address. These two conditions ensure that the router has the necessary information to forward traffic to the specified destination network using the specified outgoing interface.Rate this question:

Which of the following commands correctly configures a static route?
- A.
Ip route 10.1.3.0 255.255.255.0 10.1.130.253
- B.
Ip route 10.1.3.0 serial 0
- C.
Ip route 10.1.3.0 /24 10.1.130.253
- D.
Ip route 10.1.3.0 /24 serial 0
Correct Answer
A. Ip route 10.1.3.0 255.255.255.0 10.1.130.253Explanation
The correct answer is "ip route 10.1.3.0 255.255.255.0 10.1.130.253" because it uses the correct syntax for configuring a static route. The command specifies the destination network (10.1.3.0), the subnet mask (255.255.255.0), and the next-hop IP address (10.1.130.253). This command correctly sets up a static route for the given network.Rate this question:

Which of the following routing protocols are considered to use distance vector logic?
- A.
RIP
- B.
IGRP
- C.
EIGRP
- D.
OSPF
Correct Answer(s)
A. RIP
B. IGRPExplanation
RIP (Routing Information Protocol) and IGRP (Interior Gateway Routing Protocol) are both considered to use distance vector logic. Distance vector routing protocols determine the best path to a destination by considering the distance (or metric) to that destination. RIP and IGRP both use the hop count as their metric, which is the number of routers or hops that a packet must traverse to reach the destination. On the other hand, EIGRP (Enhanced Interior Gateway Routing Protocol) and OSPF (Open Shortest Path First) are examples of link-state routing protocols, which use more advanced algorithms to determine the best path based on factors like bandwidth, delay, and reliability.Rate this question:

Which of the following routing protocols are considered to use link-state logic?
- A.
RIP
- B.
RIP-2
- C.
OSPF
- D.
EIGRP
- E.
Integrated IS-IS
Correct Answer(s)
C. OSPF
E. Integrated IS-ISExplanation
OSPF (Open Shortest Path First) and Integrated IS-IS (Intermediate System to Intermediate System) are considered to use link-state logic. These routing protocols use a link-state database to maintain information about the network topology. They exchange information with other routers to build a complete map of the network and calculate the shortest path to each destination. RIP (Routing Information Protocol) and RIP-2 (Routing Information Protocol version 2) use distance-vector logic, while EIGRP (Enhanced Interior Gateway Routing Protocol) uses a hybrid approach combining both distance-vector and link-state elements.Rate this question:

Which of the following routing protocols are considered to be capable of converging quickly?
- A.
RIP
- B.
RIP-2
- C.
EIGRP
- D.
OSPF
- E.
Integrated IS-IS
Correct Answer(s)
C. EIGRP
D. OSPF
E. Integrated IS-ISExplanation
EIGRP, OSPF, and Integrated IS-IS are considered to be capable of converging quickly because they use advanced algorithms and techniques to calculate the shortest and most efficient paths for data packets. They also have mechanisms in place to quickly detect and respond to changes in the network topology, allowing them to adapt and reroute traffic in a timely manner. This enables these routing protocols to converge quickly and ensure efficient communication within the network.Rate this question:

- E.
Network 11.0.0.0
Correct Answer(s)
A. Router rip
C. Version 2
D. Network 10.0.0.0
E. Network 11.0.0.0Explanation
The correct answer is "router rip, version 2, network 10.0.0.0, network 11.0.0.0". This answer is correct because it includes the necessary commands to configure RIP Version 2 on Router2. The "router rip" command enables RIP routing protocol on the router. The "version 2" command specifies that RIP Version 2 should be used. The "network 10.0.0.0" command advertises all interfaces with addresses in the 10.0.0.0 network. Similarly, the "network 11.0.0.0" command advertises all interfaces with addresses in the 11.0.0.0 network.Rate this question:

- B.
A ping 10.1.13.3 command from PC1 succeeded, but a ping 172.16.2.4 did not.
- C.
A ping 10.1.1.1 command from PC1 succeeded, but a ping 10.1.13.1 did not.
- D.
A ping 10.1.1.10 command from PC1 succeeded.
Correct Answer
A. A ping 10.1.1.1 command on PC1 did not succeed.Explanation
If the ping command to 10.1.1.1 did not succeed, it indicates a problem at Layer 3 (network layer) or above. This is because the ping command uses ICMP (Internet Control Message Protocol) which operates at the network layer. Therefore, the issue is unlikely to be at Layer 1 or 2 (physical or data link layer) as stated in the question.Rate this question:

All the devices in the figure just booted, and none of the devices has yet sent any data frames. Both PCs use statically configured IP addresses. Then PC1 successfully pings PC2. Which of the following ARP table entries would you expect to see?
- A.
An entry on PC1’s ARP cache for IP address 172.16.2.7
- B.
An entry on PC1’s ARP cache for IP address 10.1.1.1
- C.
An entry on R1’s ARP cache for IP address 10.1.1.10
- D.
An entry on R1’s ARP cache for IP address 172.16.2.7
Correct Answer(s)
B. An entry on PC1’s ARP cache for IP address 10.1.1.1
C. An entry on R1’s ARP cache for IP address 10.1.1.10Explanation
When PC1 successfully pings PC2, it needs to know the MAC address of PC2 in order to send the ICMP packets. PC1 will send an ARP request asking for the MAC address of PC2's IP address (172.16.2.7). PC2 will respond with its MAC address, and PC1 will update its ARP cache with this information. Therefore, we would expect to see an entry on PC1's ARP cache for IP address 172.16.2.7. Similarly, when PC1 wants to send the ICMP packets to PC2, it needs to know the MAC address of the default gateway (R1) which has the IP address 10.1.1.10. PC1 will send an ARP request for the MAC address of R1, and R1 will respond with its MAC address. Therefore, we would expect to see an entry on R1's ARP cache for IP address 10.1.1.10.Rate this question:

PC1 is successfully pinging PC2 in the figure. Which of the following is true about the packets?
- A.
The frame going left-to-right, as it crosses the left-side LAN, has a destination MAC address of R1’s MAC address.
- B.
The frame going left-to-right, as it crosses the right-side LAN, has a destination MAC address of R2’s MAC address.
- C.
The frame going left-to-right, as it crosses the serial link, has a destination IP address of PC2’s IP address.
- D.
The frame going right-to-left, as it crosses the left-side LAN, has a source MAC address of PC2’s MAC address.
- E.
The frame going right-to-left, as it crosses the right-side LAN, has a source MAC address of PC2’s MAC address.
Correct Answer(s)
A. The frame going left-to-right, as it crosses the left-side LAN, has a destination MAC address of R1’s MAC address.
C. The frame going left-to-right, as it crosses the serial link, has a destination IP address of PC2’s IP address.
E. The frame going right-to-left, as it crosses the right-side LAN, has a source MAC address of PC2’s MAC address.Explanation
The first statement is true because when the frame is crossing the left-side LAN, it needs to reach the router R1, so the destination MAC address will be R1's MAC address. The second statement is also true because when the frame is crossing the serial link, it needs to reach PC2, so the destination IP address will be PC2's IP address. The fifth statement is true because when the frame is going right-to-left and crossing the right-side LAN, the source MAC address will be PC2's MAC address.Rate this question:
