Q321. When deploying redundant route reflectors in BGP, which attribute can you configure on the route reflector to allow routes to be identified as belonging to the same group? 

A. ROUTER_ID 

B. CLUSTER_ID 

C. ORIGINATOR_ID 

D. PEER_GROUP 

Answer:

Explanation: 

Together, a route reflector and its clients form a cluster. When a single route reflector is deployed in a cluster, the cluster is identified by the router ID of the route reflector. The bgp cluster-id command is used to assign a cluster ID to a route reflector when the cluster has one or more route reflectors. Multiple route reflectors are deployed in a cluster to increase redundancy and avoid a single point of failure. When multiple route reflectors are configured in a cluster, the same cluster ID is assigned to all route reflectors. This allows all route reflectors in the cluster to recognize updates from peers in the same cluster and reduces the number of updates that need to be stored in BGP routing tables.

Q322. Which two options are actions that EEM can perform after detecting an event? (Choose two.) 

A. Place a port in err-disabled. 

B. Generate an SNMP trap. 

C. Reload the Cisco IOS Software. 

D. Send an SMS. 

Answer: B,C 

Explanation: 

action snmp-trap 

To specify the action of generating a Simple Network Management Protocol (SNMP) trap when an Embedded Event Manager (EEM) applet is triggered, use the action snmp-trap command in applet configuration mode. 

ction reload 

To specify the action of reloading the Cisco IOS software when an Embedded Event Manager (EEM) applet is triggered, use the action reload command in applet configuration mode.

Q323. Which component of the BGP ORF can you use to permit and deny routing updates? 

A. match 

B. action 

C. AFI 

D. SAFI 

E. ORF type 

Answer:

Q324. What is the purpose of EIGRP summary leaking? 

A. to allow a summary to be advertised conditionally on specific criteria 

B. to allow a component of a summary to be advertised in addition to the summary 

C. to allow overlapping summaries to exist on a single interface 

D. to modify the metric of the summary based on which components of the summary are operational 

Answer:

Explanation: 

When you do manual summarization, and still you want to advertise some specific routes to the neighbor, you can do that using leak-map. Please read more about leaking routes here.

Q325. Which two statements about SNMP traps are true? (Choose two.) 

A. They are sent by an agent after a specified event. 

B. They are sent when solicited after a specified event. 

C. They are equivalent to a community string. 

D. They provide solicited data to the manager. 

E. They are sent by a management station to an agent. 

F. Vendor-specific traps can be configured. 

Answer: A,F 

Explanation: 

The SNMP agent contains MIB variables whose values the SNMP manager can request or change. A manager can get a value from an agent or store a value into the agent. The agent gathers data from the MIB, the repository for information about device parameters and network data. The agent can also respond to a manager's requests to get or set data. An agent can send unsolicited traps to the manager. Traps are messages alerting the SNMP manager to a condition on the network. Traps can mean improper user authentication, restarts, link status (up or down), MAC address tracking, closing of a TCP connection, loss of connection to a neighbor, or other significant events.

Q326. You are installing a new device to replace a device that failed. The configuration of the failed device is stored on a networked server, and the new device has an RXBOOT image installed. Under which condition does the streamlined Setup mode fail? 

A. The last four bits of the configuration register are not equal to the decimal value 0 or 1. 

B. The startup configuration file was deleted. 

C. Bit 6 is set in the configuration register. 

D. The startup configuration is corrupt. 

Answer:

Explanation: 

The lowest four bits of the configuration register (bits 3, 2, 1, and 0) form the boot field. The boot field determines if the router boots manually, from ROM, or from Flash or the network. To change the boot field value and leave all other bits set to their default values, follow these guidelines: 

. If you set the configuration register boot field value to 0x0, you must boot the operating system manually with the boot command. 

. If you set the configuration register boot field value to 0x1, the router boots using the default ROM software. 

. If you set the configuration register boot field to any value from 0x2 to 0xF, the router uses the boot field value to form a default boot filename for booting from a network server. For more information about the configuration register bit settings and default filenames, refer to the appropriate router hardware installation guide.

Q327. DRAG DROP 

Drag and drop the MPLS term on the left to the function it performs on the right. 

Answer: 

Q328. Which two statements about OSPF are true? (Choose two.) 

A. External type 2 routes are preferred over interarea routes. 

B. Intra-area routes are preferred over interarea routes. 

C. External type 1 routes are preferred over external type 2 routes. 

D. External type 1 routes are preferred over intra-area routes. 

E. External type 2 routes are preferred over external type 1 routes. 

Answer: B,C 

Q329. In a nonbackbone OSPF area, all traffic that is destined to the Internet is routed by using a default route that is originated by the ABR. Which change in the configuration of the OSPF area type causes traffic from that area that is destined to the Internet to be dropped? 

A. The OSPF area changes from NSSA to totally stubby area. 

B. The OSPF area changes from NSSA to regular area. 

C. The OSPF area changes from stub area to totally stubby area. 

D. The OSPF area changes from stub area to NSSA. 

Answer:

Explanation: 

The ABR for the NSSA generates the default route, but not by default. To force the ABR to generate the default route, use the area <area id> nssa default-information originate command. The ABR generates a Type 7 LSA with the link-state ID 0.0.0.0 and is advertised inside the NSSA. This default route will be propagated inside the NSSA as Type 7 LSA

Q330. A floating static route appears in the routing table of an interface even when the interface is unusable. 

Which action can you take to correct the problem? 

A. Remove the permanent option from the static route. 

B. Correct the administrative distance. 

C. Configure the floating static route to point to another route in the routing table. 

D. Correct the DHCP-provided route on the DHCP server.
