QUESTION NO:39

Which two statements are correct about Nonstop Forwarding? (Choose two.)

A. It allows the standby RP to take control of the device after a hardware or software fault on the

active RP.

B. It is a Layer 3 function that works with SSO to minimize the amount of time a network is

unavailable to users following a switchover.

C. It is supported by the implementation of EIGRP, OSPF, RIPv2, and BGP protocols.

D. It synchronizes startup configuration, startup variables, and running configuration.

E. The main objective of NSF is to continue forwarding IP packets following a switchover.

F. Layer 2 802.1w or 802.1s must be used, as 802.1d cannot process the Layer 2 changes.

G. Routing protocol tuning parameters must be the same as the NSF parameters, or failover will

be inconsistent.

Answer: B,E

Explanation: Explanation

Cisco Nonstop Forwarding (NSF) works with the Stateful Switchover (SSO) feature in Cisco IOS

software. NSF works with SSO to minimize the amount of time a network is unavailable to its

users following a switchover. The main objective of Cisco NSF is to continue forwarding IP

packets following a Route Processor (RP) switchover.

QUESTION NO:13

Which two statements are true about traffic shaping? (Choose two.)

A. Out-of-profile packets are queued.

B. It causes TCP retransmits.

C. Marking/remarking is not supported.

D. It does not respond to BECN and ForeSight Messages.

E. It uses a single/two-bucket mechanism for metering.

Answer: A,C

Explanation:

QUESTION NO:4

Refer to the exhibit.

R1 has an EBGP session to ISP 1 and an EBGP session to ISP 2. R1 receives the same prefixes

through both links.

Which configuration should be applied so that the link between R1 and ISP 2 will be preferred for

outgoing traffic (R1 to ISP 2)?

A. Increase local preference on R1 for received routes

B. Decrease local preference on R1 for received routes

C. Increase MED on ISP 2 for received routes

D. Decrease MED on ISP 2 for received routes

Answer: A

Explanation: Explanation

Local preference is an indication to the AS about which path has preference to exit the AS in order

to reach a certain network. A path with higher local preference is preferred more. The default value

of preference is 100.

QUESTION NO:32

Which two tunneling techniques support IPv6 multicasting? (Choose two.)

A. 6to4

B. 6over4

C. ISATAP

D. 6PE

E. GRE

Answer: B,E

Explanation:

When IPv6 multicast is supported (over a 6to4 tunnel), an IPv6 multicast routing protocol must be

used

Restrictions for Implementing IPv6 Multicast

IPv6 multicast for Cisco IOS software uses MLD version 2. This version of MLD is fully backward-

compatible with MLD version 1 (described in RFC 2710). Hosts that support only MLD version 1

will interoperate with a router running MLD version 2. Mixed LANs with both MLD version 1 and

MLD version 2 hosts are likewise supported.

IPv6 multicast is supported only over IPv4 tunnels in Cisco IOS Release 12.3(2)T, Cisco IOS

Release 12.2

(18)S, and Cisco IOS Release 12.0(26)S.

When the bidirectional (bidir) range is used in a network, all routers in that network must be able to

understand the bidirectional range in the bootstrap message (BSM).

IPv6 multicast routing is disabled by default when the ipv6 unicast-routing command is configured.

On Cisco Catalyst 6500 and Cisco 7600 series routers, the ipv6 multicast-routing also must be

enabled in order to use IPv6 unicast routing

QUESTION NO:1

Which two commands are required to enable multicast on a router, knowing that the receivers only

support IGMPv2? (Choose two.)

A. ip pim rp-address

B. ip pim ssm

C. ip pim sparse-mode

D. ip pim passive

Answer: A,C

Explanation:

Sparse mode logic (pull mode) is the opposite of Dense mode logic (push mode), in Dense mode

it is supposed that in every network there is someone who is requesting the multicast traffic so

PIM-DM routers begin by flooding the multicast traffic out of all their interfaces except those from

where a prune message is received to eliminate the

QUESTION NO:34

In order to maintain security, with which hop count are IPv6 neighbor discovery packets sent?

A. 0

B. 1

C. 255

D. 256

Answer: C

Explanation:

QUESTION NO:26

Refer to the exhibit.

Why is AS 65333 in parentheses?

A. It is an external AS.

B. It is a confederation AS.

C. It is the AS of a route reflector.

D. It is our own AS.

E. A route map has been applied to this route.

F. The BGP next hop is unreachable.

Answer: B

QUESTION NO:35

Which command will define a VRF with name ‘CCIE’ in IPv6?

A. ip vrf CCIE

B. ipv6 vrf CCIE

C. vrf definition CCIE

D. ipv6 vrf definition CCIE

Answer: C

Explanation:

QUESTION NO:12

Which two options are contained in a VTP subset advertisement? (Choose two.)

A. followers field

B. MD5 digest

C. VLAN information

D. sequence number

Answer: C,D

Explanation:

Subset Advertisements

When you add, delete, or change a VLAN in a Catalyst, the server Catalyst where the changes are

made increments the configuration revision and issues a summary advertisement. One or several

subset advertisements follow the summary advertisement. A subset advertisement contains a list

of VLAN information.

If there are several VLANs, more than one subset advertisement can be required in order to

advertise all the VLANs.

Subset Advertisement Packet Format

This formatted example shows that each VLAN information field contains information for a different

VLAN. It is ordered so that lowered-valued ISL VLAN IDs occur first:

Most of the fields in this packet are easy to understand. These are two clarifications:

QUESTION NO:25

Refer to the exhibit.

After a link flap in the network, which two EIGRP neighbors will not be queried for alternative

paths? (Choose two.)

A. 192.168.1.1

B. 192.168.3.7

C. 192.168.3.8

D. 192.168.3.6

E. 192.168.2.1

F. 192.168.3.9

Answer: B,C

Explanation:

Explanation

Both 192.168.3.7 and 192.168.3.8 are in an EIGRP Stub area

The Enhanced Interior Gateway Routing Protocol (EIGRP) Stub Routing feature improves network

stability, reduces resource utilization, and simplifies stub router configuration.

Stub routing is commonly used in a hub and spoke network topology. In a hub and spoke network,

one or more end (stub) networks are connected to a remote router (the spoke) that is connected to

one or more distribution routers (the hub). The remote router is adjacent only to one or more

distribution routers. The only route for IP traffic to follow into the remote router is through a

distribution router. This type of configuration is commonly used in WAN topologies where the

distribution router is directly connected to a WAN. The distribution router can be connected to

many more remote routers. Often, the distribution router will be connected to 100 or more remote

routers. In a hub and spoke topology, the remote router must forward all nonlocal traffic to a

distribution router, so it becomes unnecessary for the remote router to hold a complete routing

table. Generally, the distribution router need not send anything more than a default route to the

remote router.

When using the EIGRP Stub Routing feature, you need to configure the distribution and remote

routers to use EIGRP, and to configure only the remote router as a stub. Only specified routes are

propagated from the remote (stub) router. The router responds to queries for summaries,

connected routes, redistributed static routes, external routes, and internal routes with the message

“inaccessible.” A router that is configured as a stub will send a special peer information packet to

all neighboring routers to report its status as a stub router. Any neighbor that receives a packet

informing it of the stub status will not query the stub router for any routes, and a router that has a

stub peer will not query that peer. The stub router will depend on the distribution router to send the

proper updates to all peers.
