Q71. Which two BGP attributes are optional, non-transitive attributes? (Choose two.) 

A. AS path 

B. local preference 

C. MED 

D. weight 

E. cluster list 

Answer: C,E 

Q72. DRAG DROP 

Drag and drop the OSPF network type on the left to the correct traffic type category on the right. 

Answer: 

Q73. DRAG DROP 

Drag and drop the PPPoE packet type on the left to the corresponding description on the right. 

Answer: 

Q74. In which two situations is an EIGRP hello packet sent as unicast? (Choose two.) 

A. during neighbor discovery 

B. when link costs change 

C. when the neighbor command is used 

D. when an ACK is sent 

Answer: C,D 

Q75. Which two features are supported when Cisco HDLC is implemented? (Choose two.) 

A. error recovery 

B. error detection 

C. asynchronous links 

D. multiple protocols 

Answer: B,D 

Explanation: 

HDLC’s frame check sequence (FCS) is a 16-bit CRC-CCITT or a 32-bit CRC-32 computed over the Address, Control, and Information fields. It provides a means by which the receiver can detect errors that may have been induced during the transmission of the frame, such as lost bits, flipped bits, and extraneous bits. Cisco’s HDLC contains a proprietary field that is used to support multiple protocols.

Q76. 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:

Q77. Which three statements about VTP version 3 are true? (Choose three.) 

A. It supports other databases in addition to VLAN. 

B. It supports VLANs up to 4095. 

C. It supports the synchronization of switch configuration templates between switches in the domain. 

D. It supports the transfer of information about private VLAN structures. 

E. It supports the transfer of PVST+ configuration information. 

F. It supports RSTP. 

Answer: A,B,D 

Explanation: 

Much work has gone into improving the usability of VTP version 3 in three major areas: 

. The new version of VTP offers better administrative control over which device is allowed to update other devices' view of the VLAN topology. The chance of unintended and disruptive changes is significantly reduced, and availability is increased. The reduced risk of unintended changes will ease the change process and help speed deployment. 

. Functionality for the VLAN environment has been significantly expanded. Two enhancements are most beneficial for today's networks: 

– In addition to supporting the earlier ISL VLAN range from 1 to 1001, the new version supports the whole IEEE 802.1Q VLAN range up to 4095. 

– In addition to supporting the concept of normal VLANs, VTP version 3 can transfer information regarding Private VLAN (PVLAN) structures. 

. The third area of major improvement is support for databases other than VLAN (for example, MST).

Q78. DRAG DROP 

Drag and drop the argument of the ip cef load-sharing algorithm command on the left to the function it performs on the right. 

Answer: 

Q79. You are backing up a server with a 1 Gbps link and a latency of 2 ms. Which two statements about the backup are true? (Choose two.) 

A. The bandwidth delay product is 2 Mb. 

B. The default TCP send window size is the limiting factor. 

C. The default TCP receive window size is the limiting factor. 

D. The bandwidth delay product is 500 Mb. 

E. The bandwidth delay product is 50 Mb. 

Answer: A,C 

Explanation: 

1 Gbps is the same as 1000 Mbps, and 1000Mb x .0002 = 2 Mbps. With TCP based data transfers, the receive window is always the limiting factor, as the sender is generally able to send traffic at line rate, but then must wait for the acknowledgements to send more data. 

Q80. Which three options are characteristics of a Type 10 LSA? (Choose three.) 

A. It is an area-local, opaque LSA. 

B. Data is flooded to all routers in the LSA scope. 

C. It is used for traffic-engineering extensions to OSPF. 

D. It is a link-local, opaque LSA. 

E. Data is flooded only to the routers in the LSA scope that understand the data. 

F. It is used for traffic-engineering extensions to LDP. 

Answer: A,B,C
