Refer to the exhibit. Company ABC expanded its business and recently opened a new branch office in another country. IPv6 addresses have been used for the company network. The data servers Server1 and Server2 run applications which require end-to-end functionality, with unmodified packets that are forwarded from the source to the destination. The edge routers R1 and R2 support dual stack configuration. What solution should be deployed at the edge of the company network in order to successfully interconnect both offices?
a manually configured IPv6 tunnel between the edge routers R1 and R2
140
Refer to the exhibit. Which statement correctly describes how Router1 processes an FTP request packet that enters interface S0/0/0, and is destined for an FTP server at IP address 172.16.1.5?
The router matches the incoming packet to the statement that was created by the access-list 101 permit ip any 172.16.1.0 0.0.0.255 command, ignores the remaining statements in ACL 101, and allows the packet into the router.
141
Which characteristic of VPN technology prevents the contents of data communications from being read by unauthorized parties?
confidentiality
142
Which technology is used to dynamically map next hop, network layer addresses to virtual circuits in a Frame Relay network?
Inverse ARP
143
Refer to the exhibit. A technician is teaching a trainee to interpret the results of various Frame Relay troubleshooting commands. What conclusion can be drawn from the output that is shown?
To reach 192.168.3.1, the Branch router will use the virtual circuit that is identified by DLCI 177.
144
Where does a service provider assume responsibility from a customer for a WAN connection?
demarcation point
145
A company has its headquarters office in Dallas and five branch offices located in New York, Chicago, Los Angeles, Seattle, and Atlanta. WAN links are used for communications among offices in six sites. In planning the WAN links, the network designer is given two requirements: (1) minimize cost and (2) provide a certain level of WAN link reliability with redundant links. Which topology should the network designer recommend?
partial mesh
146
Refer to the exhibit. A system administrator must provide connectivity to a foreign network for ten hosts in a small remote office. The commands that are listed in the exhibit were entered into the router that connects the foreign network. The users in the remote office report occasional failure to connect to resources in the foreign network. What is the likely problem?
The translated address pool is not correctly sized
147
An issue of response time has recently arisen on an application server. The new release of a software package has also been installed on the server. The configuration of the network has changed recently. To identify the problem, individuals from both teams responsible for the recent changes begin to investigate the source of the problem. Which statement applies to this situation?
It will be difficult to isolate the problem if two teams are implementing changes independently.
148
Which method is most effective in protecting the routing information that is propagated between routers on the network?
Configure routing protocol authentication
149
Refer to the exhibit. What happens if the network administrator issues the commands shown when an ACL called Managers already exists on the router?
The commands are added at the end of the existing Managers ACL.
150
Which statement accurately describes a role that is played in establishing a WAN connection?
Data link layer protocols like PPP and HDLC define how data is encapsulated for transmission across a WAN link.
151
What are two main components of data confidentiality? (Choose two.)
encapsulation
| encryption
152
When NAT is in use, what is used to determine the addresses that can be translated on a Cisco router?
access control list
153
Refer to the exhibit. Branch A has a non-Cisco router that is using IETF encapsulation and Branch B has a Cisco router. After the commands that are shown are entered, R1 and R2 fail to establish the PVC. The R2 LMI is Cisco, and the R1 LMI is ANSI. The LMI is successfully established at both locations. Why is the PVC failing?
The IETF parameter is missing from the frame-relay map ip 10.10.10.1 201 command.
154
Refer to the exhibit. RIPv2 has been configured on all routers in the network. Routers R1 and R3 have not received any RIP routing updates. What will fix the issue?
Enable RIP authentication on R2.
155
A network administrator can ping the Perth router, but gets a ‘Password Required but None Set’ message when trying to connect remotely via Telnet. Which command sequence must be applied to the Perth router to allow remote access?
Router(config)# line vty 0 4 Router(config-line)# login Router(config-line)# password cisco
156
A router does not load its configuration after a power failure. After running the show startup-configuration command, the administrator finds that the original configuration is intact. What is the cause of this problem?
The configuration register is set for 0×2142.
