The implementations group has been using the test bed to do a `proof-of-concept' that requires both Client 1 and Client 2 to access the WEB Server at 184.108.40.206. After several changes to the network addressing, routing schemes, DHCP services, NTP services, layer 2 connectivity, FHRP services, and device security, a trouble ticket has been opened indicating that Client 1 cannot ping the 220.127.116.11 address. Use the supported commands to isolate the cause of this fault and answer the following question. What is the solution to the fault condition?
Under the IP DHCP pool configuration, issue the no ipdhcp excluded-address 10.2.1.1 10.2.1.253 command and enter the ipdhcp excluded-address 10.2.1.1 10.2.1.2 command.
Which statement is true about an IPsec/GRE tunnel?
GRE encapsulation occurs before the IPsec encryption process.
Which IPsec mode will encrypt a GRE tunnel to provide multiprotocol support and reduced overhead?

The implementations group has been using the test bed to do a `proof-of-concept'. After several changes to the network addressing, routing schemes, a trouble ticket has been opened indicating that the loopback address on R1 (2026::111:1) is not able to ping the loopback address on DSW2(2026::102:1). Use the supported commands to isolated the cause of this fault and answer the following questions. The fault condition is related to which technology?
IPv6 OSPF Routing
You have 2 NTP servers in your network - 10.1.1.1 and 10.1.1.2. You want to configure a Cisco router to use 10.1.1.2 as its NTP server before falling back to 10.1.1.1. Which commands will you use to configure the router?
ntp server 10.1.1.1ntp server 10.1.1.2 prefer
When troubleshooting an EIGRP connectivity problem, you notice that two connected EIGRP routers are not becoming EIGRP neighbors. A ping between the two routers was successful. What is the next thing that should be checked?
Verify that EIGRP is enabled for the appropriate networks on the local and neighboring router.
What is the result of configuring the logging console warning command?
Warning, critical, alert, and emergency messages will be logged on the console.
You have the followings commands on your Cisco Router: ip ftp username admin ip ftp password backup You have been asked to switch from FTP to HTTP. Which two commands will you use to replace the existing commands?
ip http client username admin
ip http client password backup
Refer to the shown below. %LINK-3-UPDOWN: Interface Serial0/0, changed state to up %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0/0, changed state to up What statement is correct regarding the output shown in the graphic?
The first log message is an error message with a severity level of 3.
In computer networking a multicast address is an identifier for a group of hosts that have joined a multicast group. Multicast addressing can be used in the Link Layer (OSI Layer 2), such as Ethernet Multicast, as well as at the Internet Layer (OSI Layer 3) as IPv4 or IPv6 Multicast. Which two descriptions are correct regarding multicast addressing?
To calculate the Layer 2 multicast address, the host maps the last 23 bits of the IP address into the last 24 bits of the MAC address. The high-order bit is set to 0.
The first 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.
You want to enhance the security within the Company LAN and prevent VLAN hopping. What two steps can be taken to help prevent this? (Select two)
Place unused ports in a common unrouted VLAN
Prevent automatic trunk configuration
FCAPS is a network maintenance model defined by ISO. It stands for which of the following ?
A MAC address flood attack is occurring on the Company LAN. During this attack, numerous frames are forwarded to a switch which causes the CAM table to fill to capacity. How does this action benefit the attacker?
All traffic is flooded out all ports and an attacker is able to capture all data.
Which three features are benefits of using GRE tunnels in conjunction with IPsec for building site-to-site VPNs? (Choose three.)
allows dynamic routing over the tunnel
supports multi-protocol (non-IP) traffic over the tunnel
simplifies the ACL used in the crypto map
The implementations group has been using the test bed to do a ,,proof-of-concept that requires both Client 1 and Client 2 to access the WEB Server at 18.104.22.168. After several changes to the network addressing, routing schemes, DHCP services, NTP services, layer 2 connectivity, FHRP services, and device security, a trouble ticket has been opened indicating that Client 1 cannot ping the 22.214.171.124 address. Use the supported commands to isolate the cause of this fault and answer the following question. What is the solution to the fault condition?
Under the IP DHCP pool configuration, issue the no ip dhcp excluded-address 10.2.1.1 10.2.1.253 command and enter the ip dhcp excluded-address 10.2.1.1 10.2.1.2 command.
The Company network is being flooded with invalid Layer 2 addresses, causing switch CAM tables to be filled and forcing unicast traffic to be transmitted out all switch ports. Which type of Layer 2 attack is being used here?
MAC address flooding
You enabled CDP on two Cisco Routers which are connected to each other. The Line and Protocol status for the interfaces on both routers show as UP but the routers do not see each other a CDP neighbors. Which layer of the OSI model does the problem most likely exist?
The following command is issued on a Cisco Router: Router(configuration)#logging console warnings Which alerts will be seen on the console?
warnings, errors, critical, alerts, emergencies
EIGRP is being used as the routing protocol on the Company network. While troubleshooting some network connectivity issues, you notice a large number of EIGRP SIA (Stuck in Active) messages. What causes these SIA routes? (Select two)
The neighboring router is too busy to answer the query (generally caused by high CPU utilization).
The neighboring router is having memory problems and cannot allocate the memory to process the query or build the reply packet.
A technician is troubleshooting connectivity problems between two routers that are directly connected through a serial line. The technician notices that the serial line is up, but cannot see any neighbors displayed in the output of the show cdp neighbors command. In which OSI layer is the problem most likely occurring?
The following commands are issued on a Cisco Router: Router(configuration)#access-list 199 permit tcp host 10.1.1.1 host 172.16.1.1 Router(configuration)#access-list 199 permit tcp host 172.16.1.1 host 10.1.1.1 Router(configuration)#exit Router#debug ip packet 199 What will the debug output on the console show?
All IP Packets between 10.1.1.1 and 172.16.1.1
What is the result if you configure two devices with the ntp server command?
The NTP protocol will determine which server is most reliable and will synchronize to that server.
Which two of the following options are categories of Network Maintenance tasks?
At which layer of the OSI model does the Spanning Tree Protocol (STP) operate at?
Refer to the configuration statements shown in the graphic above. R1(config)#access-list 199 permit tcp host 10.1.1.1 host 172.16.1.1 R1(config)#access-list 199 permit tcp host 172.16.1.1 host 10.1.1.1 R1(config)#end R1#debug ip packet 199 detail Which statement reflects what the effect is of this configuration sequence?
These commands turn on debug ip packet only for packets between hosts 10.1.1.1 and 172.16.1.1.
What are two approaches to maintaining a network?(Choose two.)
Which two statements about the Cisco Aironet Desktop Utility (ADU) are true? (Select two)
The Aironet Desktop Utility (ADU) can support only one wireless client adapter installed and used at a time.
The Aironet Desktop Utility (ADU) can be used to establish the association between the client adapter and the access point, manage authentication to the wireless network, and enable encryption.
