第1题:

A. DHCPDISCOVER packets will reach the DHCP server.
B. The router will not forward DHCPDIS COVER packets because it has not been configured to do so.
C. This configuration is applied to interface Fa0/1.
D. DHCPDISCOVER packets will not reach the DHCP server because DHCPDISCOVER packets are broadcasts.
E. DHCPDISCOVER packets will not reach the DHCP server because ports 67 and 68 have not been explicitly allowed by the ip forward - protocol command.
F. This configuration is applied to interface Fa0/0.
第2题:
Which three statements are true about the data traffic characteristics of voice traffic? ()
第3题:
You are maintaining your database in Oracle10g. You are performing an incomplete recovery because the tablespace, DATA1, was dropped and purged from the Recycle Bin. After performing an incomplete recovery, you open the database with the RESETLOGS option. What will NOT be the impact of using the RESETLOGS option?()
第4题:
When troubleshooting a network, the output of the command show interfaces indicates a large number of runts. What is a runt?()
第5题:
The number of packets (or flows) dropped because they do not conform to the ASA/PIX security policy can be viewed using what command? ()
第6题:
Why is QoS important in a converged network?()
第7题:
Interface congestion is causing drops in voice packets and TCP packets. The drops result in jerky speech quality and slower FTP traffic flows. Which two technologies would proactively address the TCP transfer rate and the voice problems?()
第8题:
Perform Export before TSPITR and Import after TSPITR
Move objects to another schema that has the same tablespace assigned
Perform Incomplete Recovery before TSPITR with the Log Sequence Number (LSN)
Perform Incomplete Recovery before TSPITR with the System Change Number (SCN)
第9题:
latency must be kept below 150 ms
latency is not a concern as long as jitter is kept below 30 ms
voice packets do not require a specific type of queuing
voice packets are rather small
voice packets require TCP for rapid retransmission of dropped packets
voice packets require a fairly constant bandwidth reserved for voice control traffic as well as forthe voice payload
第10题:
packets per second
number of remote sites
throughput bandwidth
number of tunnels

What two statistics appear in show frame-relay map output?()
第20题:
the number of packets that are discarded because they exceed the maximum packet size of the medium
errors created when the CRC generated by the originating LAN station or far-end device does not match the checksum calculated from the data received.
the number of packets that are discarded because they are smaller than the minimum packet size of the medium
the number of received packets that were ignored by the interface because the interface hardware ran low on internal buffers
the number of times that the interface requested another interface within the router to slow down
第21题:

Move objects to another schema that has the same tablespace assigned
Perform Incomplete Recovery before TSPITR with the Log Sequence Number (LSN)
Perform Incomplete Recovery before TSPITR with the System Change Number (SCN)
第22题:
Video conferencing traffic tends to be much more bursty in nature and is more prone to have an impact on other traffic flows.
Latency requirements are less stringent for video traffic than for voice traffic.
Video traffic is less sensitive to dropped packets than for voice traffic.
Video traffic requires the retransmission capabilities of TCP whereas voice uses UDP.
Voice traffic tends to be much more bursty in nature and is more prone to have an impact on other traffic flows.
Voice traffic requires the retransmission capabilities of TCP whereas video uses UDP.
第23题:
Queuing introduces equal delays for packets of the same flow, resulting in jitter.
When congestion occurs, dropping affects most of the TCP sessions, which simultaneously back off and then restart again.
All buffers can temporarily be seized by aggressive flows, and normal TCP flows experience buffer starvation.
There is no differentiated drop mechanism. Higher priority traffic is dropped in the same way as best-effort traffic.
In TCP starvation, traffic exceeds the queue limit because of the bursty nature of packet networks. A router cannot handle multiple concurrent TCP sessions.
Global synchronization occurs because multiple TCP hosts reduce their transmission rates at random intervals in response to packet dropping
第24题:
QoS and IPSec should never be used together.
IKE/ISAKMP packets are DiffSERV codepoint CS6, so the traffic is never dropped.
Source IKE/ISAKMP packets off the loop-back address.
Classify IKE/ISAKMP packets so they are appropriately prioritized.
