To a router, a flow is a(66)of packets that share the same Characterstics, such as traveling the same(67),using the same(68),having the same kind of security, and so on. A router that supports the handling of flow labels has a(69)table. The table has an entry for each active flow label; each entry defines the(70)required by the corresponding flow label.
A.sequence
B.stream
C.Queues
D.flow
第1题:
A.source IP address
B.source MAC address
C.egress interface
D.ingress interface
E.destination IP address
F.IP next-hop

第10题:
It configures a router to send all packets out interface serial 0/0.
It configures a router to block routing updates from being sent out interface serial 0/0.
It configures a router as a firewall, blocking all unauthorized packets from exiting serial 0/0.
It configures a router to send all packets for unknown destination networks out interface serial 0/0.
It configures a router to drop all packets for which the destination network is unknown.
第11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12题:
Fast switching reducesa routers CPU utilization, compared to process switching
All packets of a flow, except for the first packet, use the information in the fast cache
It can be enabled with the interface command ip route-cache
Fast switching uses a fast cache maintained in a router’s control plane
The fast cache contains information about how traffic from different data flows should beforwarded
Even though the fast switching is enabled, the first packet of a flow is still process switched

第17题:
You are the network consultant from Cisco.com. Please point out two statements correctly describe an IPS device()
第18题:
Users can define policy to control traffic flow between which two components? ()(Choose two.)
第19题:
Packets can arrive out of order.
Packets must take the same path to the destination.
Once packets are received at the destination router, the router performs sampling to ensure the quality of the voice traffic.
Packets can experience varying delays across the network.
Packets containing voice samples are sequentially numbered by default, allowing for reordering upon arrival at the terminal router along the path.
第20题:
Twenty bytes of header will be replaced with five bytes.
If the IPSec transform set includes Authentication Header, the receiving IPSec peer will discard the packets.
The IPSec packets will be dropped by Router A's compression logic.
The voice packets will not be compressed.
第21题:

The neighboring router starts receiving route updates from this router.
A failure causes traffic on a link between two neighboring routers to flow in only one direction(unidirectional link).
Th e neighboring router stops receiving ACK packets from this router.

A failure causes traffic on a link between two neighboring routers to flow in only one direction(unidirectional link)
The neighboring router stops receiving ACK packets from this router

classify the packets
flow manager emits an action for the packets
enforce the action determined by the flow manager
