QUESTION 31
Which two Cisco Express Forwarding tables are located in the data plane? (Choose two.)
A. the forwarding information base
B. the label forwarding information base
C. the IP routing table
D. the label information table
E. the adjacency table
Correct Answer: AB Explanation
Explanation/Reference: http://www.pass4cert.net/70-480-dumps-download.html
The control plane runs protocols such as OSPF, BGP, STP, LDP. These protocols are needed so that routers and switches know how to forward packets and
frames.
The data plane is where the actual forwarding takes place. The data plane is populated based on the protocols running in the control plane. The Forwarding
Information Base (FIB) is used for IP traffic and the Label FIB is used for MPLS.
QUESTION 32
Which option is the most effective action to avoid packet loss due to microbursts?
A. Implement larger buffers.
B. Install a faster CPU.
C. Install a faster network interface.
D. Configure a larger tx-ring size.
Correct Answer: A Explanation
Explanation/Reference:
You can’t avoid or prevent them as such without modifying the sending host’s application/network stack so it smoothes out the bursts. However, you can manage microbursts by tuning the size of receive buffers / rings to absorb occasional microbursts.
QUESTION 33
Which two statements about packet fragmentation on an IPv6 network are true? (Choose two.)
A. The fragment header is 64 bits long.
B. The identification field is 32 bits long.
C. The fragment header is 32 bits long.
D. The identification field is 64 bits long.
E. The MTU must be a minimum of 1280 bytes.
F. The fragment header is 48 bits long.
Correct Answer: AB Explanation cisco-200-125 ccna pdf
Explanation/Reference:
The fragment header is shown below, being 64 bits total with a 32 bit identification field: Reference: http://www.openwall.com/presentations/IPv6/img24.html
QUESTION 34
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.
Correct Answer: AC Explanation Explanation/Reference:
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.
QUESTION 35
Which two pieces of information does RTCP use to inform endpoint devices about the RTP flow? (Choose two.)
A. the transmitted octet
B. the lost packet count
C. session control function provisioning information
D. the CNAME for session participants
E. the authentication method
F. MTU size changes in the path of the flow Correct Answer: AB
Explanation Explanation/Reference:
RTCP transports statistics for a media connection and information such as transmitted octet and packet counts, packet loss, packet delay variation, and round-trip delay time. An application may use this information to control quality of service parameters, perhaps by limiting flow, or using a different codec.
QUESTION 36
How many hash buckets does Cisco Express Forwarding use for load balancing?
A. 8
B. 16
C. 24
D. 32
Correct Answer: B Explanation Explanation/Reference:
In order to understand how the load balance takes place, you must first see how the tables relate. The Cisco Express Forwarding table points to 16 hash buckets (load share table), which point to the adjacency table for parallel paths. Each packet to be switched is broken up into the source and destination address pair and checked against the loadshare table.
QUESTION 37
Which three features require Cisco Express Forwarding? (Choose three.)
A. NBAR
B. AutoQoS
C. fragmentation
D. MPLS
E. UplinkFast
F. BackboneFast
Recognition.
QoS Features That Require CEF These class-based QoS features are supported only on routers that run CEF. Network Based Application Recognition (NBAR) provides intelligent network classification. For more information, refer to Network Based Application
The AutoQoS -VoIP feature simplifies and speeds up the implementation and provisioning of QoS for VoIP traffic. This feature is enabled with the help of the
auto qos voip command. CEF must be enabled at the interface or ATM PVC before the auto qos command can be used. For more information about this feature and its prerequisites, refer to AutoQoS – VoIP.
From MPLS Fundamentals – Luc De Ghein Why Is CEF Needed in MPLS Networks? Concerning MPLS, CEF is special for a certain reason; otherwise, this book would not explicitly cover it. Labeled packets that enter the router are switched according to the label forwarding information base (LFIB) on the router. IP packets that enter the router are switched according to the CEF table on the router. Regardless of whether the packet is switched according to the LFIB or the CEF table, the outgoing packet can be a labeled packet or an IP packet
QUESTION 38
Which two options are interface requirements for turbo flooding? (Choose two.)
A. The interface is Ethernet.
B. The interface is configured for ARPA encapsulation.
C. The interface is PPP.
D. The interface is configured for GRE encapsulation.
E. The interface is configured for 802.1Q encapsulation.
Correct Answer: AB Explanation Explanation/Reference: http://www.cisco.com/c/en/us/training-events/training-certifications/exams/current-list/ccie-routing-switching.html
In the switch, the majority of packets are forwarded in hardware; most packets do not go through the switch CPU. For those packets that do go to the CPU, you can speed up spanning tree-based UDP flooding by a factor of about four to five times by using turbo-flooding. This feature is supported over Ethernet interfaces configured for ARPA encapsulation.

QUESTION 39
Which three options are sub-subfields of the IPv4 Option Type subfield? (Choose three.)
A. Option Class
B. GET
C. Copied
D. PUSH
E. Option Number
F. TTL
Correct Answer: ACE Explanation Explanation/Reference:
Each IP option has its own subfield format, generally structured as shown below. For most options, all three subfields are used. Option Type, Option Length and Option Data.
