1、1.Which address provides an example of an IPv6 link-local address? FE80:1324:ABCD 2001:2345:AB12:1935:FEFF 2001:1234:0000:9CA:0876/64 1234:ABCD:5678:EF00:9234:AA22:5527:FC35 2.Refer to the exhibit. A network administrator has issued the commands that are shown on Router1 and Router2. A later review
2、of the routing tables reveals that neither router is learning the LAN network of the neighbor router. What is most likely the problem with the RIPng configuration? The serial interfaces are in different subnets. The RIPng process is not enabled on interfaces. The RIPng network command is not configu
3、red. The RIPng processes do not match between Router1 and Router2. 3.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
4、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 new
5、WAN service supporting only IPv6 NAT overload to map inside IPv6 addresses to outside IPv4 address a manually configured IPv6 tunnel between the edge routers R1 and R2 static NAT to map inside IPv6 addresses of the servers to an outside IPv4 address and dynamic NAT for the rest of the inside IPv6 ad
6、dresses4.Refer to the exhibit. PC1, PC2, and PC3 are configured with dynamic address assignments. PC2 is assigned an IP address from the DHCP server. What would account for the IP addresses that are currently assigned to PC1 and PC3? Switch S2 port Fa0/12 is configured for full-duplex. These address
7、es were included in the DHCP server pools. Router R1 has a misconfigured IP address on interface Fa1/0. R1 interface Fa0/0 is not in the same network as the DHCP server. R1 interfaces Fa0/0 and Fa1/0 do not include the ip helper-address command. 5.Refer to the exhibit. A host connected to Fa0/0 is u
8、nable to acquire an IP address from this DHCP server. The output of the debug ip dhcp server command shows “DHCPD: there is no address pool for 192.168.1.1“. What is the problem? The 192.168.1.1 address has not been excluded from the DHCP pool. The pool of addresses for the 192Network pool is incorr
9、ect. The default router for the 192Network pool is incorrect. The 192.168.1.1 address is already configured on Fa0/0.6.Refer to the exhibit. PAT has been implemented on router R2. PC1 and PC2 are unsuccessful when attempting to connect to Internet resources. What is a possible cause? No NAT pool is
10、configured. The “inside“ and “outside“ interfaces are switched. The access control list is configured with an incorrect access list number. The access control list is missing a statement for the 10.94.6.0 network. The ip nat inside source list 1 interface command is pointing to the wrong serial inte
11、rface. 7.When NAT is in use, what is used to determine the addresses that can be translated on a Cisco router? access control list routing protocol inbound interface ARP cache 8.What name is given to the location where a customer network interfaces with a network that is owned by another organizatio
12、n? CPE DCE local loop demarcation point 9.Which additional functionality is available on an interface when the encapsulation is changed from HDLC to PPP? flow control error control authentication synchronous communication 10.Refer to the exhibit. What statement is true about the core router devices?
13、 They use multiport internetworking devices to switch traffic such as Frame Relay, ATM, or X.25 over the WAN. They provide internetworking and WAN access interface ports that are used to connect to the service provider network. They provide termination for the digital signal and ensure connection in
14、tegrity through error correction and line monitoring. They support multiple telecommunications interfaces of the highest speed and are able to forward IP packets at full speed on all of those interfaces.11.Which encapsulation protocol when deployed on a Cisco router over a serial interface is only c
15、ompatible with another Cisco router? PPP SLIP HDLC Frame Relay12.Refer to the exhibit. Which data transmission technology is being represented? TDM PPP HDLC SLIP 13.Which combination of authentication and Layer 2 protocol should be used to establish a link between a Cisco and a non-Cisco router with
16、out sending authentication information in plain text? CHAP and HDLC CHAP and PPP PAP and HDLC PAP and PPP 14.Refer to the exhibit. The link between the CTRL and BR_1 routers is configured as shown in the exhibit. Why are the routers unable to establish a PPP session? The clock rate must be 56000. The usernames are misconfigured. The IP addresses are on different subnets. The clock rate is configured on the wrong end of the link. The CHAP passwords must be different on the two routers. Interfa
