Correct
Incorrect
-
Question 8 of 27
8. Question
1 pointsWhat is identified within the opcode of an EIGRP packet header?Correct
Incorrect
Hint
The EIGRP packet header opcode is used to identify the EIGRP packet type: update (1), query (3), reply (4), and hello (5). -
Question 9 of 27
9. Question
1 pointsWhich table is used by EIGRP to store all routes that are learned from EIGRP neighbors?Correct
Incorrect
Hint
EIGRP routers maintain a topology table that includes entries for every destination that the router learns from directly connected EIGRP neighbors. -
Question 10 of 27
10. Question
1 pointsWhen an EIGRP-enabled router uses a password to accept routes from other EIGRP-enabled routers, which mechanism is used?Correct
Incorrect
Hint
EIGRP authentication allows a router to accept routing information only from other routers that are configured with the same password. -
Question 11 of 27
11. Question
1 pointsWhich destination MAC address is used when a multicast EIGRP packet is encapsulated into an Ethernet frame?Correct
Incorrect
Hint
When an EIGRP multicast packet is encapsulated into an Ethernet frame, the destination MAC address is 01-00-5E-00-00-0A. -
Question 12 of 27
12. Question
1 pointsWhat is the purpose of using protocol-dependent modules in EIGRP?Correct
Incorrect
Hint
EIGRP is designed to route several network layer protocols by using the PDMs. For example, EIGRP can be used to route both IPv4 and IPv6, as well as other network layer protocols. There is a separate instance of PDM for different network layer protocols. -
Question 13 of 27
13. Question
1 pointsIf all router Ethernet interfaces in an EIGRP network are configured with the default EIGRP timers, how long will a router wait by default to receive an EIGRP packet from its neighbor before declaring the neighbor unreachable?Correct
Incorrect
Hint
EIGRP uses the hold time as the maximum time it should wait for receiving a hello packet (or other EIGRP packets) from its neighbor before declaring that the neighbor is unreachable. By default the hold time is 3 times greater than the hello interval. On LAN interfaces, the default hello time is 5 seconds and the default hold time is 15 seconds. -
Question 14 of 27
14. Question
1 pointsWhich command or commands must be entered on a serial interface of a Cisco router to restore the bandwidth to the default value of that specific router interface?Correct
Incorrect
Hint
The command used to restore the default bandwidth on a serial interface of a Cisco router is no bandwidth. The default bandwidth on most, but not all, Cisco router serial interfaces is 1544 kb/s. -
Question 15 of 27
15. Question
1 pointsWhich two factors does an EIGRP router use to determine that a route to a remote network meets the feasible condition and is therefore loop-free? (Choose two.)Correct
Incorrect
-
Question 16 of 27
16. Question
1 pointsWhy would a network administrator use a wildcard mask in the network command when configuring a router to use EIGRP?Correct
Incorrect
-
Question 17 of 27
17. Question
1 pointsRefer to the exhibit. R3 has two possible paths to the 172.16.99.0 network. What is the reported distance of the feasible successor route?Correct
Incorrect
Hint
A feasible successor route is a backup route to the primary successor route, displayed as the second subentry in the command output. The reported distance of the feasible successor route for the 172.16.99.0 network is 2816. -
Question 18 of 27
18. Question
1 pointsWhich statement describes a characteristic of the delivery of EIGRP update packets?Correct
Incorrect
Hint
EIGRP uses a reliable delivery protocol to send update packets. Depending on the need, EIGRP may send update packets with unicast or multicast. For example, update packets are sent as a multicast when required by multiple routers, or as a unicast when required by only a single router. -
Question 19 of 27
19. Question
1 pointsAn administrator issues the router eigrp 100 command on a router. What is the number 100 used for?Correct
Incorrect
Hint
The router eigrp 100 command uses the number as a process-id to keep track of the running instance of the EIGRP process, as several EIGRP processes can be run at the same time. This number is called autonomous system number. -
Question 20 of 27
20. Question
1 pointsWhich two EIGRP packet types are sent with unreliable delivery? (Choose two.)Correct
Incorrect
Hint
The update, query, and reply EIGRP packet types require reliable delivery. -
Question 21 of 27
21. Question
1 pointsA network administrator wants to verify the default delay values for the interfaces on an EIGRP-enabled router. Which command will display these values?Correct
Incorrect
Hint
The show interfaces command is used to show the delay, in microseconds, of a specified interface. This command will also provide the default delay value or an administratively configured value. The show running-config command will only display an administratively configured value. The commands show ip route and show ip protocols will not provide the delay value of each interface. -
Question 22 of 27
22. Question
1 pointsOpen the PT Activity. Perform the tasks in the activity instructions and then answer the question. Which code is displayed on the web server?Correct
Incorrect
Hint
To complete the activity: 1. Enable IPv6 routing globally on R2 using the ipv6 unicast-routing command 2. Configure IPv6 EIGRP on the router, assign the router IP, and enable it, using the following commands: ipv6 router eigrp 100 eigrp router-id 10.0.0.2 no shutdown 3. Configure the Gi0/0 and S0/0/0 interfaces with the ipv6 eigrp 100 command To test your configuration: On PC0, click on the Desktop tab, open the web browser, and type www.netacad.net -
Question 23 of 27
23. Question
1 pointsA new network administrator has been asked to verify the metrics that are used by EIGRP on a Cisco device. Which two EIGRP metrics are measured by using static values on a Cisco device? (Choose two.)Correct
Incorrect
Hint
Bandwidth and delay are static values that are not actually tracked by a device. Load and reliability are tracked dynamically by a device over a default period of time. MTU is not used for EIGRP metrics. -
Question 24 of 27
24. Question
1 pointsQuestion as presented:Sort elements
- eigrp roter-id command
- highest IPv4 address on loopback interfaces
- highest IPv4 address on active physical interfaces
- highest priority on active physical interfaces
-
first
-
second
-
third
Correct
Incorrect
Hint
EIGRP needs a router ID to uniquely identify routers in an EIGRP domain. A router will use any manually configured router ID first. If a router ID is not manually configured, the router will choose an ID based on the interface with the highest IPv4 address. Because loopback interfaces are more stable than physical interfaces, the highest IPv4 address on a loopback will be used as the router ID. If there is no loopback interface configured, then the highest IPv4 address on any physical interface will be used. -
Question 25 of 27
25. Question
1 pointsQuestion as presented:Sort elements
- source address for EIGRP messages is a routable address
- source address for EIGRP messages is a link-local address
- uses a 32-bit router ID
- use Dijkstra's algorithm
-
EIGRP IPv4 only
-
EIGRP IPv6 only
-
both EIGRP for IPv4 and EIGRP for IPv6
Correct
Incorrect
-
Question 26 of 27
26. Question
1 pointsWhat protocol is use by EIGRP to deliver EIGRP packets to neighbors?Correct
Incorrect
Hint
Because EIGRP can route non-IP protocols it cannot use, TCP or UDP for reliable EIGRP packet delivery. Instead it uses Reliable Transport Protocol (RTP). -
Question 27 of 27
27. Question
1 pointsWhich condition will cause DUAL to put an EIGRP route into the active state?Correct
Incorrect
Hint
DUAL will put an EIGRP route into the active state if the successor becomes unavailable and there is no feasible successor in the topology table. When a network enters the active state, DUAL must query neighbors for a new successor.
