C. Cisco IOS 

D. Host manager 

Answer:

Explanation: 

Some of the processes are listed in the table below: 

Process 

Purpose 

Affected FRUs 

SubPackage Mapping 

Host Manager

SIP (one instance per SIP) 

ESP (one instance per ESP) 

RPControl 

SIPBase 

ESPBase 

Interface Manager 

Provides an interface between the IOS process and the per-SPA interface processes on the SIP. 

RP (one instance per RP) 

SIP (one instance per SIP) 

RPControl 

SIPBase 

IOS 

The IOS process implements all forwarding and routing features for the router. 

RP (one per software redundancy instance per RP). Maximum of two instances per RP. 

RPIOS 

Forwarding Manager 

Manages the downloading of configuration to each of the ESPs and the communication of forwarding plane information, such as statistics, to the IOS process. 

RP (one per software redundancy instance per RP). Maximum of two instances per RP. 

ESP (one per ESP) 

RPControl 

ESPBase

Q62. Which two statements about redistribution are true? (Choose two.) 

A. When BGP traffic is redistributed into OSPF, the metric is set to 1 unless the metric is defined. 

B. When EIGRP routes on a CE are redistributed through a PE into BGP, the Cost Community POI is set automatically. 

C. When OSPF traffic is redistributed into BGP, internal and external routes are redistributed. 

D. When BGP traffic is redistributed into OSPF, eBGP and iBGP routes are advertised. 

E. iBGP routes automatically redistribute into the IGP if the routes are in the routing table. 

F. When EIGRP traffic is redistributed into BGP, a default metric is required. 

Answer: A,B 


Q63. DRAG DROP 

Drag each spanning-tree feature on the left to the matching statement on the right. 

Answer: 


Q64. On a network using RIPng, the prefix field of a routing table entry has a value of 0:0:0:0:0:0:0:0. What does this value signify? 

A. The next hop address is unknown. 

B. The next hop address is a site-local address. 

C. The neighboring router has IPv6 ND disabled. 

D. The next hop address must be the originator of the route advertisement. 

E. The associated route follows a default route out of the network. 

Answer:


Q65. DRAG DROP 

Drag and drop the fragmentation characteristics on the left to the corresponding protocol on the right. 

Answer:

Q66. Refer to the exhibit. 

Which two issues can cause the interface VLAN10 to be down/down? (Choose two.) 

A. The VLAN is inactive or has been removed from the VLAN database. 

B. STP is in a forwarding state on the port. 

C. A Layer 2 access port is configured with VLAN10, but is in a down/down state. 

D. The autostate exclude feature was used on interface VLAN10. 

Answer: A,C 


Q67. Refer to the exhibit. 

Which three statements about the R1 configuration are true? (Choose three.) 

A. The virtual circuit identifier is 1611 and the virtual circuit is down. 

B. The local label for the circuit is 4006. 

C. The targeted LDP session to the remote peer is up. 

D. The local label for the circuit is 1611. 

E. The virtual circuit identifier is 4006 and the virtual circuit is down. 

F. The circuit is using MPLS VC type 4. 

Answer: A,B,C 

Explanation: 

The number after the vc is the identifier, which is 1611 in this case. Here, the VC status is shown as down. 

As shown, the MPLS VC labels: local 4006, remote unassigned shows the local label used is 4006. 

The targeted LDP session is up as verified by the “Signalling protocol: LDP, peer 172.16.12.70 up” statement in the output. 


Q68. Which two statements about BPDU guard are true? (Choose two.) 

A. The global configuration command spanning-tree portfast bpduguard default shuts down interfaces that are in the PortFast-operational state when a BPDU is received on that port. 

B. The interface configuration command spanning-tree portfast bpduguard enable shuts down only interfaces with PortFast enabled when a BPDU is received. 

C. BPDU guard can be used to prevent an access port from participating in the spanning tree in the service provider environment. 

D. BPDU guard can be used to protect the root port. 

E. BPDU guard can be used to prevent an invalid BPDU from propagating throughout the network. 

Answer: A,C 


Q69. Refer to the exhibit. 

Which statement is true? 

A. It is impossible for the destination interface to equal the source interface. 

B. NAT on a stick is performed on interface Et0/0. 

C. There is a potential routing loop. 

D. This output represents a UDP flow or a TCP flow. 

Answer:

Explanation: 

In this example we see that the source interface and destination interface are the same (Et0/0). Typically this is seen when there is a routing loop for the destination IP address. 


Q70. Which two configuration changes should be made on the OTP interface of an EIGRP OTP route reflector? (Choose two.) 

A. passive-interface 

B. no split-horizon 

C. no next-hop-self 

D. hello-interval 60, hold-time 180 

Answer: B,C 

Explanation: 

The EIGRP Over the Top feature enables a single end-to-end Enhanced Interior Gateway Routing Protocol (EIGRP) routing domain that is transparent to the underlying public or private WAN transport that is used for connecting disparate EIGRP customer sites. When an enterprise extends its connectivity across multiple sites through a private or a public WAN connection, the service provider mandates that the enterprise use an additional routing protocol, typically the Border Gateway Protocol (BGP), over the WAN links to ensure end-to-end routing. The use of an additional protocol causes additional complexities for the enterprise, such as additional routing processes and sustained interaction between EIGRP and the routing protocol to ensure connectivity, for the enterprise. With the EIGRP Over the Top feature, routing is consolidated into a single protocol (EIGRP) across the WAN. 

Perform this task to configure a customer edge (CE) device in a network to function as an EIGRP Route Reflector: 

1. enable 

2. configure terminal 

3. router eigrp virtual-name 

4. address-family ipv4 unicast autonomous-system as-number 

5. af-interface interface-type interface-number 

6. no next-hop-self 

7. no split-horizon 

8. exit 

9. remote-neighbors source interface-type interface-number unicast-listen lisp-encap 

10. network ip-address 

11. end 

Note. Use no next-hop-self to instruct EIGRP to use the received next hop and not the local outbound interface address as the next hop to be advertised to neighboring devices. If no next-hop-self is not configured, the data traffic will flow through the EIGRP Route Reflector.
