Answer: A

Topic 5, Infrastructure Security

Question No: 53 – (Topic 5)

What is the benefit of deploying IPv6 in a campus network using dual stack mode?

  1. Dual Stack Mode takes advantage of IPv6 over IPv4 tunnel within a network.

  2. IPv4 and IPv6 run alongside one another and have no dependency on each other to function

  3. IPv4 and IPv6 share network resources.

  4. IPv6 can depend on existing IPv4 routing, QoS, security, and multicast policies.

Answer: B Explanation:

Deploying IPv6 in the campus using the dual-stack model offers several advantages over the hybrid and service block models. The primary advantage of a dual stack model is that it does not require tunneling within the campus network. The dual stack model runs the two protocols as ships in the night, meaning that IPv4 and IPv6 run alongside one another and have no dependency on each other to function except that they share network resources. Both have independent routing.

Question No: 54 – (Topic 5)

What two situations could require the use of multiple routing protocols? (Choose two)

  1. when using UNIX host-based routers

  2. when smaller broadcast domains are desired

  3. because having multiple routing protocols confuses hackers

  4. when migrating from an older Interior Gateway Protocol (IGP) to a new IGP

  5. when all equipment is manufactured by Cisco

  6. when there are multiple paths to destination networks

Answer: A,D Explanation:

Simple routing protocols work well for simple networks, but networks grow and become more complex. While running a single routing protocol throughout your entire IP internetwork is desirable, multiprotocol routing is common for a number of reasons, including company mergers, multiple departments managed by multiple network administrators, multivendor environments, or simply because the original routing protocol is

no longer the best choice. Often, the multiple protocols are redistributed into each other during a migration period from one protocol to the other.

Question No: 55 – (Topic 5)

Refer to the exhibit. Will redistributed RIP routes from OSPF Area 2 be allowed in Area 1?

Dumps4Cert 2017 PDF and VCE

  1. Because Area 1 is an NSSA, redistributed RIP routes will not be allowed.

  2. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1.

  3. Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1.

  4. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1.

  5. RIP routes will be allowed in Area 1 only if they are first redistributed into EIGRP.

Answer: A Explanation:

The following are several area types that are possible on OSPF:

Question No: 56 – (Topic 5)

A router is configured for redistribution to advertise EIGRP routes into OSPF on a boundary router. Given the configuration:

router ospf 1

redistribute eigrp 1 metric 25 subnets

What is the function of the 25 parameter in the redistribute command?

  1. It specifies the seed cost to be applied to the redistributed routes.

  2. It specifies the administrative distance on the redistributed routes.

  3. It specifies the metric limit of 25 subnets in each OSPF route advertisement.

  4. It specifies a new process-id to inject the EIGRP routes into OSPF.

Answer: A

Question No: 57 – (Topic 5)

Router E is configured with the EIGRP variance 2 command.

Dumps4Cert 2017 PDF and VCE

What path will Router E take to reach Router A?

  1. only E-D-A

  2. only E-B-A

  3. only E-C-A

  4. both E-B-A and E-C-A

  5. both E-B-A and E-D-A

  6. all available paths.

Answer: D Explanation:

By using the “variance 2 command we can share traffic to other feasible successor routes. But by default, EIGRP only shares traffic to 4 paths. So we need to use the “maximum- paths 6 to make sure all of these routes are used.

Question No: 58 – (Topic 5)

How is network layer addressing accomplished in the OSI protocol suite?

  1. Internet Protocol address

  2. Media Access Control address

  3. Packet Layer Protocol address

  4. Network Service Access Point address

  5. Authority and Format Identifier address

Answer: D Explanation:

OSI network-layer addressing is implemented by using two types of hierarchical addresses: network service access-point addresses and network-entity titles.

A network service-access point (NSAP) is a conceptual point on the boundary between the network and the transport layers. The NSAP is the location at which OSI network services are provided to the transport layer. Each transport-layer entity is assigned a single NSAP, which is individually addressed in an OSI internetwork using NSAP addresses.

D 150.150.0.0/16 [90/679936] via 116.16.35.5, 00:02:58, Serial2/0.1

Refer to the exhibit. Why is the 140.140.0.0 network not used as the gateway of last resort even though it is configured first?

  1. The last default-network statement will always be preferred.

  2. A route to the 140.140.0.0 network does not exist in the routing table.

  3. Default-network selection will always prefer the statement with the lowest IP address.

  4. A router will load balance across multiple default-networks; repeatedly issuing the show ip route command would show the gateway of last resort changing between the two networks.

Answer: B Explanation:

As you can see in the exhibit, 140.140.0.0 doesn’t appear in the routing table.

Question No: 60 – (Topic 5)

Refer to the exhibit.
