Question 1 of 50
1. Question
1 pointsThe buffers for packet processing and the running configuration file are temporarily stored in which type of router memory?
Correct
Incorrect
RAM provides temporary storage for the running IOS, the running configuration file, the IP routing table, ARP table, and buffers for packet processing. In contrast, permanent storage of the IOS is provided by flash. NVRAM provides permanent storage of the startup configuration file, and ROM.provides permanent storage of the router bootup instructions and a limited IOS.

Question 2 of 50
2. Question
1 pointsWhat is the minimum configuration for a router interface that is participating in IPv6 routing?
Correct
Incorrect
With IPv6, a router interface typically has more than one IPv6 address. The router will at least have a link-local address that can be automatically generated, but the router commonly has an global unicast address also configured.

Question 3 of 50
3. Question
1 pointsRefer to the exhibit. Assuming that the routing tables are up to date and no ARP messages are needed, after a packet leaves H1, how many times is the L2 header rewritten in the path to H2?
Correct
Incorrect
H1 creates the first Layer 2 header. The R1 router has to examine the destination IP address to determine how the packet is to be routed. If the packet is to be routed out another interface, as is the case with R1, the router strips the current Layer 2 header and attaches a new Layer 2 header. When R2 determines that the packet is to be sent out the LAN interface, R2 removes the Layer 2 header received from the serial link and attaches a new Ethernet header before transmitting the packet.

Question 4 of 50
4. Question
1 pointsWhat command will enable a router to begin sending messages that allow it to configure a link-local address without using an IPv6 DHCP server?
Correct
Incorrect
To enable IPv6 on a router you must use the ipv6 unicast-routing global configuration command or use the ipv6 enable interface configuration command. This is equivalent to entering ip routing to enable IPv4 routing on a router when it has been turned off. Keep in mind that IPv4 is enabled on a router by default. IPv6 is not enabled by default.

Question 5 of 50
5. Question
1 pointsWhich type of static route typically uses the distance parameter in the ip route global configuration command?
Correct
Incorrect
Because a floating static route is not designed to be used as a primary route, its configuration requires a higher administrative distance than the usual default value of 1. When set higher than the administrative distance for the current routing protocol, the distance parameter allows the route to be used only when the primary route fails. All other forms of static routes have specific uses as primary routes.

Question 6 of 50
6. Question
1 pointsRefer to the exhibit. Which route was configured as a static route to a specific network using the next-hop address?
Correct
Incorrect
The C in a routing table indicates an interface that is up and has an IP address assigned. The S in a routing table signifies that a route was installed using the ip route command. Two of the routing table entries shown are static routes to a specific destination (the 10.0.2.0 network). The entry that has the S denoting a static route and [1/0] was configured using the next-hop address. The other entry (S 10.0.2.0/24 is directly connected, Serial 0/0/0) is a static route configured using the exit interface. The entry with the 0.0.0.0 route is a default static route which is used to send packets to any destination network that is not specifically listed in the routing table.

Question 7 of 50
7. Question
1 pointsRefer to the exhibit. Which type of IPv6 static route is configured in the exhibit?
Correct
Incorrect
The route provided points to another address that must be looked up in the routing table. This makes the route a recursive static route.

Question 8 of 50
8. Question
1 pointsA network administrator has entered the following command:
ip route 192.168.10.64 255.255.255.192 serial0/0/1
When the network administrator enters the command show ip route, the route is not in the routing table. What should the administrator do next?
Correct
Incorrect
The reason that a correctly typed static network would not go into the routing table is if the exit interface is not available. The 192.168.10.64 is a valid network number and that route does not have to be “up and up” in order for a static route to be configured on a remote router.

Question 9 of 50
9. Question
1 pointsRefer to the exhibit. This network has two connections to the ISP, one via router C and one via router B. The serial link between router A and router C supports EIGRP and is the primary link to the Internet. If the primary link fails, the administrator needs a floating static route that avoids recursive route lookups and any potential next-hop issues caused by the multiaccess nature of the Ethernet segment with router B. What should the administrator configure?
Correct
Incorrect
A floating static route is a static route with an administrative distance higher than that of another route already in the routing table. If the route in the table disappears, the floating static route will be put into the routing table in its place. Internal EIGRP has an AD of 90, so a floating static route in this scenario would need to have an AD higher than 90. Also, when creating a static route to a multiaccess interface like a FastEthernet segment a fully specified route should be used, with both a next-hop IP address and an exit interface. This prevents the router from doing a recursive lookup, but still ensures the correct next-hop device on the multiaccess segment forwards the packet.

Question 13 of 50
13. Question
1 pointsRefer to the exhibit. Which type of route is 172.16.0.0/16?
Correct
Incorrect
A level 1 parent route displays the classful network address, the number of subnets, and the number of different subnet masks that the classful address has been subdivided into. It does not have an exit interface. A child route, ultimate route, and default route all have exit interfaces that are associated with them.

Question 15 of 50
15. Question
1 pointsWhat is the name of the layer in the Cisco borderless switched network design that would have more switches deployed than other layers in the network design of a large organization?
Correct
Incorrect
Access layer switches provide user access to the network. End user devices, such as PCs, access points, printers, and copiers, would require a port on a switch in order to connect to the network. Thus, more switches are needed in the access layer than are needed in the core and distribution layers.

Question 16 of 50
16. Question
1 pointsWhat is a function of the distribution layer?
Correct
Incorrect
The distribution layer interacts between the access layer and the core by aggregating access layer connections in wiring closets, providing intelligent routing and switching, and applying access policies to access the rest of the network. Fault isolation and high-speed backbone connectivity are the primary functions of the core layer. The main function of the access layer is to provide network access to the user.

18. Question
1 pointsA lab in a network management software company is configuring a testing environment to verify the performance of new software with different network connectivity speeds, including FastEthernet, GigabitEthernet, and 10 GigabitEthernet, and with copper and fiber optic connections. Which type of switch should the software company purchase to perform the tests?
Correct
Incorrect
A modular configuration switch is used at the distribution and core layers. A modular configuration switch usually takes 3 rack units or more. Modular configuration switches offer more flexibility in the types and number of ports as well as the expansion cards that can be used. A fixed configuration switch tends to be an access layer switch. Stackable switches are usually access layer switches that have been cabled together.

Question 20 of 50
20. Question
1 pointsWhich statement correctly describes how a LAN switch forwards frames that it receives?
Correct
Incorrect
Cut-through frame forwarding reads up to only the first 22 bytes of a frame, which excludes the frame check sequence and thus invalid frames may be forwarded. In addition to broadcast frames, frames with a destination MAC address that is not in the CAM are also flooded out all active ports. Unicast frames are not always forwarded. Received frames with a destination MAC address that is associated with the switch port on which it is received are not forwarded because the destination exists on the network segment connected to that port.

1 pointsA company security policy requires that all MAC addressing be dynamically learned and added to both the MAC address table and the running configuration on each switch. Which port security configuration will accomplish this?
Correct
Incorrect
With sticky secure MAC addressing, the MAC addresses can be either dynamically learned or manually configured and then stored in the address table and added to the running configuration file. In contrast, dynamic secure MAC addressing provides for dynamically learned MAC addressing that is stored only in the address table.

Question 24 of 50
24. Question
1 pointsA network technician is configuring port security on switches. The interfaces on the switches are configured in such a way that when a violation occurs, packets with unknown source addresses are dropped and no notification is sent. Which violation mode is configured on the interfaces?
Correct
Incorrect
On a Cisco switch, an interface can be configured for one of three violation modes, specifying the action to be taken if a violation occurs:
Protect – Packets with unknown source addresses are dropped until a sufficient number of secure MAC addresses are removed, or the number of maximum allowable addresses is increased. There is no notification that a security violation has occurred.
Restrict – Packets with unknown source addresses are dropped until a sufficient number of secure MAC addresses are removed, or the number of maximum allowable addresses is increased. In this mode, there is a notification that a security violation has occurred.
Shutdown – The interface immediately becomes error-disabled and the port LED is turned off.Hint

Question 25 of 50
25. Question
1 pointsAfter sticky learning of MAC addresses is enabled, what action is needed to prevent dynamically learned MAC addresses from being lost in the event that an associated interface goes down?
Correct
Incorrect
When sticky learning is enabled, dynamically learned MAC addresses are stored in the running configuration in RAM and will be lost if the switch is rebooted or an interface goes down. To prevent the loss of learned MAC addresses, an administrator can save the running configuration into the startup configuration in NVRAM.

1 pointsWhich DHCP IPv4 message contains the following information?
Destination address: 255.255.255.255
Client IPv4 address: 0.0.0.0
Default gateway address: 0.0.0.0
Subnet mask: 0.0.0.0Correct
Incorrect
A client will first send the DHCPDISCOVER broadcast message to find DHCPv4 servers on the network. This message will have the limited broadcast address, 255.255.255.255, as the destination address. The client IPv4 address, the default gateway address, and subnet fields will all be 0.0.0.0 because these have not yet been configured on the client. When the DHCPv4 server receives a DHCPDISCOVER message, it reserves an available IPv4 address to lease to the client and sends the unicast DHCPOFFER message to the requesting client. When the client receives the DHCPOFFER from the server, it sends back a DHCPREQUEST broadcast message. On receiving the DHCPREQUEST message, the server replies with a unicast DHCPACK message.

1 pointsA client is using SLAAC to obtain an IPv6 address for its interface. After an address has been generated and applied to the interface, what must the client do before it can begin to use this IPv6 address?
Correct
Incorrect
Stateless DHCPv6 or stateful DHCPv6 uses a DHCP server, but Stateless Address Autoconfiguration (SLAAC) does not. A SLAAC client can automatically generate an address that is based on information from local routers via Router Advertisement (RA) messages. Once an address has been assigned to an interface via SLAAC, the client must ensure via Duplicate Address Detection (DAD) that the address is not already in use. It does this by sending out an ICMPv6 Neighbor Solicitation message and listening for a response. If a response is received, then it means that another device is already using this address.

37. Question
1 pointsA network administrator is implementing DHCPv6 for the company. The administrator configures a router to send RA messages with M flag as 1 by using the interface command ipv6 nd managed-config-flag. What effect will this configuration have on the operation of the clients?
Correct
Incorrect
Under stateful DHCPv6 configuration, which is indicated by setting M flag as 1 (through the interface command ipv6 nd managed-config-flag), the dynamic IPv6 address assignments are managed by the DHCPv6 server. Clients must obtain all configuration information from a DHCPv6 server.

1 pointsRefer to the exhibit. The users on the LAN network of R1 cannot receive an IPv6 address from the configured stateful DHCPv6 server. What is missing from the stateful DHCPv6 configuration on router R1?
Correct
Incorrect
When configuring a router interface for stateful DHCPv6, the router must be able to inform the host PC’s to receive IPv6 addressing from a stateful DHCPv6 server. The interface command is ipv6 nd managed-config-flag

1 pointsRefer to the exhibit. NAT is configured on R1 and R2. The PC is sending a request to the web server. What IPv4 address is the source IP address in the packet between R2 and the web server?
Correct
Incorrect
Because the packet is between R2 and the web server, the source IP address is the inside global address of PC, 209.165.200.245.

Question 40 of 50
40. Question
1 pointsWhat is a disadvantage when both sides of a communication use PAT?
Correct
Incorrect
With the use of NAT, especially PAT, end-to-end traceability is lost. This is because the host IP address in the packets during a communication is translated when it leaves and enters the network. With the use of NAT/PAT, both the flexibility of connections to the Internet and security are actually enhanced. Host IPv4 addressing is provided by DHCP and not related to NAT/PAT.

Question 41 of 50
41. Question
1 pointsRefer to the exhibit. R1 is configured for NAT as displayed. What is wrong with the configuration?
Correct
Incorrect
R1 has to have NAT-POOL2 bound to ACL 1. This is accomplished with the command R1(config)#ip nat inside source list 1 pool NAT-POOL2. This would enable the router to check for all interesting traffic and if it matches ACL 1 it would be translated by use of the addresses in NAT-POOL2.

Question 42 of 50
42. Question
1 pointsA network engineer is configuring PAT on a router and has issued the command:
ip nat inside source list 1 interface serial 0/1/0 overload
Which additional command is required to specify addresses from the 192.168.128.0/18 network as the inside local addresses?Correct
Incorrect
A standard access list with the appropriate wildcard mask specifies the inside local addresses to be translated. The ip nat inside source list 1 pool NAT_POOL command configures NAT to use a pool of outside global addresses, not a single outside interface address as required. The ip nat inside source static 192.168.128.0 209.165.200.254 command configures one-to-one static NAT, not PAT as the overload keyword specifies.

Question 43 of 50
43. Question
1 pointsRefer to the exhibit. A company has an internal network of 192.168.10.0/24 for their employee workstations and a DMZ network of 192.168.3.0/24 to host servers. The company uses NAT when inside hosts connect to outside network. A network administrator issues the show ip nat translations command to check the NAT configurations. Which one of source IPv4 addresses is translated by R1 with PAT?
Correct
Incorrect
From the output, three IPv4 addresses (192.168.10.10, 192.168.10.15, and 192.168.10.35) are translated into the same IPv4 address (10.0.0.28) with three different ports, thus these three IPv4 addresses are translated with PAT. The IPv4 addresses 192.168.3.33 and 192.168.3.35 are translated with dynamic NAT. The IPv4 address 192.168.3.5 is translated with static NAT.

Question 44 of 50
44. Question
3 pointsRefer to the exhibit. A network administrator has just configured address translation and is verifying the configuration. What three things can the administrator verify? (Choose three.)
Correct
Incorrect
The show ip nat statistics, show ip nat translations, and debug ip nat commands are useful in determining if NAT is working and and also useful in troubleshooting problems that are associated with NAT. NAT is working, as shown by the hits and misses count. Because there are four misses, a problem might be evident. The standard access list numbered 1 is being used and the translation pool is named NAT as evidenced by the last line of the output. Both static NAT and NAT overload are used as seen in the Total translations line.

1 pointsWhich requirement should be checked before a network administrator performs an IOS image upgrade on a router?
Correct
Incorrect
Before an upgrade process starts, the user must make sure that there is sufficient space in the flash to host the new IOS image file. An old IOS file does not have to be deleted as long as there is sufficient space available for the new IOS file. FTP is not supported for the IOS upgrading process. Instead, a TFTP server is used. The new IOS image should be downloaded and loaded to the TFTP server.

1 pointsA network administrator configures a router with the command sequence:
R1(config)# boot system tftp://c1900-universalk9-mz.SPA.152-4.M3.bin
R1(config)# boot system romWhat is the effect of the command sequence?
Correct
Incorrect
The boot system command is a global configuration command that allows the user to specify the source for the Cisco IOS Software image to load. In this case, the router is configured to boot from the IOS image that is stored on the TFTP server and will use the ROMmon imagethat is located in the ROM if it fails to locate the TFTP server or fails to load a valid image from the TFTP server.
