Question No: 193 – (Topic 7)

An IPv6 overlay tunnel is required to communicate with isolated IPv6 networks across an IPv4 infrastructure. There are currently five IPv6 overlay tunnel types. Which three IPv6 overlay tunnel statements are true? (Choose three.)

  1. Overlay tunnels can only be configured between border routers capable of supporting IPv4 and IPv6.

  2. Overlay tunnels can be configured between border routers or between a border router and a host capable of supporting IPv4 and IPv6.

  3. Cisco IOS supports manual, generic, routing encapsulation (GRE), IPv6-compatible, 4to6, and multiprotocol Label Switching (MPLS) Overlay tunneling mechanism.

  4. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv4-compatible, 6to4, and Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) overlay tunneling mechanisms.

  5. A manual overlay tunnel supports point-to-multipoint tunnels capable of carrying IPv6 and Connectionless Network Service (CLNS) packets.

  6. Overlay tunneling encapsulates IPv6 packets in IPv4 packets for delivery across an IPv4 infrastructure.

Answer: B,D,F Explanation:

B:Overlay tunnels can be configured between border routers or between a border router and a host capable of supporting IPv4 and IPv6.

D. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv4-compatible, 6to4, and Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) overlay tunneling mechanisms.

F:Overlay tunneling encapsulates IPv6 packets in IPv4 packets for delivery across an IPv4 infrastructure.

Question No: 194 – (Topic 7)

Which statement about dual stack is true?

  1. Dual stack translates IPv6 addresses to IPv4 addresses.

  2. Dual stack means that devices are able to run IPv4 and IPv6 in parallel.

  3. Dual stack translates IPv4 addresses to IPv6 addresses.

  4. Dual stack changes the IP addresses on hosts from IPv4 to IPv6 automatically.

Answer: B

Question No: 195 – (Topic 7)

Which statement is true about the command ipv6 ospf 1 area 0?

  1. It must be issued in router global configuration mode to enable the OSPF process for IPv6.

  2. It must be issued in interface configuration mode to enable the OSPF process for IPv6.

  3. It must be issued before the network command to enable the OSPF process for IPv6.

  4. It must be issued after the network command to enable the OSPF process for IPv6.

Answer: B

Question No: 196 DRAG DROP – (Topic 7)

Question No: 197 – (Topic 7)

Which SNMP version provides both encryption and authentication?

  1. SNMPv4

  2. SNMPv2c

  3. SNMPv3

  4. SNMPv1

Answer: C

Question No: 198 – (Topic 7)

Refer to exhibit.

Dumps4Cert 2017 PDF and VCE

What is indicated by the show ip cef command for an address?

  1. CEF is unable to get routing information for this route.

  2. CEF cannot switch packet for this route and passes it to the next best switching method.

  3. A valid entry and is pointed to hardware based forwarding.

  4. CEF cannot switch packet for this route and drops it.

Answer: B

Explanation: Glean adjacency – in short when the router is directly connected to hosts the FIB table on the router will maintain a prefix for the subnet rather than for the individual host prefix. This subnet prefix points to a GLEAN adjacency.

Punt adjacency – When packets to a destination prefix can’t be CEF Switched, or the feature is not supported in the CEF Switching path, the router will then use the next slower switching mechanism configured on the router.

Question No: 199 – (Topic 7)

Which three items can you track when you use two time stamps with IP SLAs? (Choose three.)

  1. delay

  2. jitter

  3. packet loss

  4. load

  5. throughput

  6. path

Answer: A,B,C

Question No: 200 – (Topic 7)

Refer to the following configuration command.

router(conttg)# ip nat inside source static tcp 172.16.10.8 8080 172.16.10.8 80 Which statement about the command is true?

  1. Any packet that is received in the inside interface with a source IP port address of 172.16.10.8:80 is translated to 172.16.10.8 8:80

  2. Any packet that is received in the inside interface with a source IP address of 172 16 10 8 is redirected to port 8080 or port 80

  3. The router accepts only a TCP connection from port 8080 and port 80 on IP address 172 16 10 8

  4. Any packet that is received in the inside interface with a source IP port address of 172 16 10 8 8080 is translated to 172.16.10.8 80
