Answer:
Q42. A company is deciding between an HVR and SVR solution in order to finalize a virtualization project proposal. Which is an advantage of a HVR solution versus a SVR solution?
A. A HVR solution implements dedicated data plane resources.
B. A HVR solution implements shared control plane resources.
C. A HVR solution introduces significant contention of resources.
D. A HVR solution implements dedicated chassis resources.
Answer: A
Explanation:
Comparison of Virtualized Routing Architectures
Category Hardware-Isolated Virtual Router Software-Isolated Virtual Router
Control plane resources (CPU, memory)
Dedicated
Shared
Data plane resources (forwarding engine, queues)
Dedicated
Shared
Chassis resources (power supplies, blowers, fabric)
Shared
Shared
Management, configuration
Dedicated
Typically shared, but varies depending on degree of virtualization
Connections between virtualized routing entities
Typically external
Typically internal, but possibly external
Per-chassis scalability (routing adjacencies, prefixes)
Increased with additional logical routers
Unaffected by additional virtual routers

Q43. Which OSPF configuration suppresses the periodic OSPF hello packets?
A. router ospf 1
area0
interface GigabitEthernet 0/1
passive
B. router ospf 1
area0
interface GigabitEthernet 0/1
C. router ospf 1
area 0
interface GigabitEthernet 0/1
stub-router
router-lsa r-bit

Q44. Refer to the exhibit. R1 and R2 are multicast routers running PIM over Serial1/0. The PIM adjacency on R1 is not forming with the given configuration. What command can be entered on R1 to resolve the issue?
A. no access-list 100 deny 103 any any
B. no access-list 100 deny udp any anyeq 103
C. no access-list 100 deny ip any host 224.0.0.1
D. no access-list 100 deny ip any host 224.0.0.2
Answer: A
Explanation:
All PIM protocols share a common control message format. PIM control messages are sent as raw IP datagrams (protocol number 103), either multicast to the link-local ALL PIM
ROUTERS multicast group, or unicast to a specific destination.

Q45. SSO was configured on a Cisco ASR 1006 Router by using two RPs. When the main RP failed, a service disruption occurred. What are two reasons that the SSO did not work? (Choose two.)
A. The standby RP has a different DRAM configuration than the primary RP.
B. HSRP and NSF are not configured.
C. The ESP that is installed in the Cisco ASR 1006 Router does not support SSO.
D. The standby RP was not ready to switch over when the primary RP failed.
E. The standby RP has a different IOS version than the primary RP.
Answer: B,E
