Q41. Which statement about the use of tunneling to migrate to IPv6 is true?
A. Tunneling is less secure than dual stack or translation.
B. Tunneling is more difficult to configure than dual stack or translation.
C. Tunneling does not enable users of the new protocol to communicate with users of the old protocol without dual-stack hosts.
D. Tunneling destinations are manually determined by the IPv4 address in the low-order 32 bits of IPv4-compatible IPv6 addresses.
Answer: C
Explanation:
Using the tunneling option, organizations build an overlay network that tunnels one protocol over the other
by encapsulating IPv6 packets within IPv4 packets and IPv4 packets within IPv6 packets. The advantage of this approach is that the new protocol can work without disturbing the old protocol, thus providing connectivity between users of the new protocol. Tunneling has two disadvantages, as discussed in RFC 6144: Users of the new architecture cannot use the services of the underlying infrastructure.
Tunneling does not enable users of the new protocol to communicate with users of the old protocol without
dual-stack hosts, which negates interoperability.

Q42. Which Cisco IOS VPN technology leverages IPsec, mGRE, dynamic routing protocol, NHRP, and Cisco Express Forwarding?
A. FlexVPN
B. DMVPN
C. GETVPN
D. Cisco Easy VPN
Answer: B
Explanation: Dynamic Multipoint Virtual Private Network (DMVPN) is a dynamic tunneling form of a virtual
private network (VPN) supported on Cisco IOS-based routers and Unix-like Operating Systems based on
the standard protocols, GRE, NHRP and IPsec. This DMVPN provides the capability for creating a
dynamic-mesh VPN network without having to pre-configure (static) all possible tunnel end-point peers,
including IPsec (Internet Protocol Security) and ISAKMP (Internet Security Association and Key
Management Protocol) peers. DMVPN is initially configured to build out a hub-and-spoke network by
statically configuring the hubs (VPN headends) on the spokes, no change in the configuration on the hub is
required to accept new spokes. Using this initial hub-and-spoke network, tunnels between spokes can be
dynamically built on demand (dynamic-mesh) without additional configuration on the hubs or spokes. This
dynamic-mesh capability alleviates the need for any load on the hub to route data between the spoke
networks. DMVPN is combination of the following technologies:
Multipoint GRE (mGRE)
Next-Hop Resolution Protocol (NHRP)
Dynamic Routing Protocol (EIGRP, RIP, OSPF, BGP)
Dynamic IPsec encryption
Cisco Express Forwarding (CEF)

53. Which traffic does the following configuration allow?
ipv6 access-list cisco
permit ipv6 host 2001:DB8:0:4::32 any eq ssh
line vty 0 4
ipv6 access-class cisco in
A. all traffic to vty 0 4 from source 2001:DB8:0:4::32
B. only ssh traffic to vty 0 4 from source all
C. only ssh traffic to vty 0 4 from source 2001:DB8:0:4::32
D. all traffic to vty 0 4 from source all
Answer: C
Explanation:
Here we see that the IPv6 access list called "cisco" is being applied to incoming VTY connections to the
router. IPv6 access list has just one entry, which allows only the single IPv6 IP address of 2001:DB8:0:4::32 to connect using SSH only.
Q43. Which PPP authentication method sends authentication information in cleartext?
A. MS CHAP
B. CDPCP
C. CHAP
D. PAP
Answer: D
Explanation:
Q44. Refer to the exhibit.
Which command only announces the 1.2.3.0/24 network out of FastEthernet 0/0?
A. distribute list 1 out
B. distribute list 1 out FastEthernet0/0
C. distribute list 2 out
D. distribute list 2 out FastEthernet0/0
Answer: D
Explanation:
Access list 2 is more specific, allowing only 1.2.3.0/24, whereas access list 1 permits all 1.0.0.0/8
networks. This question also asks us to apply this distribute list only to the outbound direction of the fast Ethernet 0/0 interface, so the correct command is "distribute list 2
out FastEthernet0/0."
Q45. Router A and Router B are configured with IPv6 addressing and basic routing capabilities using OSPFv3. The networks that are advertised from Router A do not show up in Router B's routing table. After debugging IPv6 packets, the message "not a router" is found in the output. Why is the routing information not being learned by Router B?
A. OSPFv3 timers were adjusted for fast convergence.
B. The networks were not advertised properly under the OSPFv3 process.
C. An IPv6 traffic filter is blocking the networks from being learned via the Router B interface that is connected to Router A.
D. IPv6 unicast routing is not enabled on Router A or Router B.
Answer: D

Q46. After a recent DoS attack on a network, senior management asks you to implement better logging functionality on all IOS-based devices. Which two actions can you take to provide enhanced logging results? (Choose two.)
A. Use the msec option to enable service time stamps.
B. Increase the logging history .
C. Set the logging severity level to 1.
D. Specify a logging rate limit.
E. Disable event logging on all noncritical items.
Answer: A,B
Explanation:
The optional msec keyword specifies the date/time format should include milliseconds. This can aid in
pinpointing the exact time of events, or to correlate the order that the events happened. To limit syslog messages sent to the router's history table and to an SNMP network management station based on severity, use the logging history command in global configuration mode. By default, Cisco devices Log error messages of severity levels 0 through 4 (emergency, alert, critical, error, and warning levels); in other words, "saving level warnings or higher." By increasing the severity level, more granular monitoring can occur, and SNMP messages will be sent by the less sever (5-7) messages.
Q47. Which three characteristics are shared by subinterfaces and associated EVNs? (Choose three.)
A. IP address
B. routing table
C. forwarding table
D. access control lists
E. NetFlow configuration
Answer: A,B,C
Explanation:
A trunk interface can carry traffic for multiple EVNs. To simplify the configuration process, all
the subinterfaces and associated EVNs have the same IP address assigned. In other words, the trunk
interface is identified by the same IP address in different EVN contexts. This is accomplished as a result of
each EVN having a unique routing and forwarding table, thereby enabling support for overlapping IP
addresses across multiple EVNs. Reference: http://www.cisco.com/en/US/docs/ios-xml/ios/evn/

Q48. A network engineer is configuring a solution to allow failover of HSRP nodes during maintenance windows, as an alternative to powering down the active router and letting the network respond accordingly. Which action will allow for manual switching of HSRP nodes?
A. Track the up/down state of a loopback interface and shut down this interface during maintenance.
B. Adjust the HSRP priority without the use of preemption.
C. Disable and enable all active interfaces on the active HSRP node.
D. Enable HSRPv2 under global configuration, which allows for maintenance mode.
Answer: A
Explanation:
The standby track command allows you to specify another interface on the router for the
HSRP process to monitor in order to alter the HSRP priority for a given group. If the line protocol of the
specified interface goes down, the HSRP priority is reduced. This means that another HSRP router with
higher priority can become the active router if that router has standby preempt enabled. Loopback
interfaces can be tracked, so when this interface is shut down the HSRP priority for that router will be
lowered and the other HSRP router will then become the active one. Reference: http://www.cisco.com/c/

Q49. Which switching method is used when entries are present in the output of the command show ip cache?
A. fast switching
B. process switching
C. Cisco Express Forwarding switching
D. cut-through packet switching
Answer: A
Explanation:
Fast switching allows higher throughput by switching a packet using a cache created by the initial packet
sent to a particular destination. Destination addresses are stored in the high-speed cache to expedite forwarding. Routers offer better packet-transfer performance when fast switching is enabled. Fast switching is enabled by default on all interfaces that support fast switching.
To display the routing table cache used to fast switch IP traffic, use the "show ip cache" EXEC command.

Q50. How does an IOS router process a packet that should be switched by Cisco Express Forwarding without an FIB entry?

Answer: B
