CCDA 640-863 Real Exam Questions

This exam indicates a foundation or apprentice knowledge of network design for the Cisco converged networks based on SONA (Cisco’s Service-Oriented Network Architecture). CCDA certified professionals can design routed and switched network infrastructures and services involving LAN, WAN, and broadband access for businesses and organizations.

1: Which statement accurately describes one difference between a small office and medium office topology?
A.Small offices commonly use Rapid PVST+ for Layer 3 deployments.
B.Medium offices commonly use integrated route and switching platforms.
C.Medium offices use integrated 10/100/1000 interfaces as Layer 2 trunks.
D.Medium offices use external access switches to support LAN connectivity.
Correct Answers: D

2: Which three factors best justify WAN link redundancy between geographically dispersed sites? (Choose three.)
A.important traffic flows
B.lack of speed
C.high link utilization
D.uncertain reliability
E.excessive packet transmission rate
F.high expense of transmitting data
Correct Answers: A B D

3: Which two of these represent a best practice implementation of a Split MAC LWAPP deployment in a Cisco Unified Wireless Network? (Choose two.)
A.Each wireless client authentication type maps to a shared SSID which in turn maps to a common shared VLAN.
B.Each wireless client authentication type maps to a unique SSID which in turn maps to a unique VLAN.
C.Each wireless client authentication type maps to a unique SSID which in turn maps to a common shared VLAN.
D.802.1Q trunking extends from the wired infrastructure to the access point for translation into SSID(s).
E.802.1Q trunking extends from the wired infrastructure to a wireless LAN controller for translation into SSID(s).
F.802.1Q trunking extends from the wired infrastructure to a wireless LAN controller. Then the 802.1Q packet is encapsulated in LWAPP and sent to the access point for transmission over the SSID(s).
Correct Answers: B E

4: Which two statements represent advantages that the top-down network design process has over the bottom-up network design process? (Choose two.)
A.is able to provide the big picture
B.utilizes previous experience
C.takes less time to design a network
D.identifies appropriate technologies first
E.provides a design for current and future development
Correct Answers: A E

5: Which two of these are required for wireless client mobility deployment when using a Cisco Unified Wireless Network? (Choose two.)
A.assigned master controller
B.matching mobility group name
C.matching RF group name
D.matching RF power
E.matching security
F.matching RF channel
Correct Answers: B E

6: Which two VoIP characteristics are affected most by codec choice? (Choose two.)
A.voice quality
B.silent packet handling
C.voice packet header size
D.bandwidth required for voice calls
Correct Answers: A D

7: Which H.323 protocol controls call setup between endpoints?
A.H.225
B.H.245
C.RAS
D.RTCP
Correct Answers: B

8: A company is designing a worldwide IPv6 network with duplicated file servers at multiple locations. Each file server contains identical reference information. Which IPv6 address type would be used to allow each end station to send a request to the nearest file server using the same destination address, regardless of the location of that end station?
A.unicast
B.anycast
C.multicast
D.broadcast
Correct Answers: B

9: Which two techniques can reduce voice packet transfer delay across a link of less than 512 kbps? (Choose two.)
A.deploy LFI
B.increase queue depth
C.increase link bandwidth
D.extend the trust boundary
E.deploy software compression
Correct Answers: A C

10: Your company’s Cisco routers are operating with EIGRP. You need to join networks with an acquisition’s heterogeneous routers at 3 sites, operating with EIGRP and OSPF. Which describes the best practice for routing protocol deployment?
A.apply OSPF throughout both networks
B.apply one-way redistribution exclusively at each location
C.apply two-way redistribution exclusively at each location
D.apply two-way redistribution at each location with a route filter at only one location
E.apply two-way redistribution at each location with a route filter at each location
F.apply EIGRP with the same autonomous system throughout both networks
Correct Answers: E
