第7题:
SCREEN options offer protection against various attacks
SCREEN options are deployed prior to route and policy processing in first path packet processing
SCREEN options are deployed at the ingress and egress sides of a packet flow
SCREEN options, you must take special care to protect OSPF
第8题:
The receiver acknowledges the final packet in each communications stream.
The receiver adds sequencing numbers to the packets received.
The sender adds sequencing numbers to the packets it sends.
The receiver acknowledges each packet it receives from the sending device.
第9题:
SCREEN options are deployed at the ingress and egress sides of a packet flow.
Although SCREEN options are very useful, their use can result in more session creation.
SCREEN options offer protection against various attacks at the ingress zone of a packet flow.
SCREEN options examine traffic prior to policy processing, thereby resulting in fewer resouces used formalicious packet processing.
第10题:
The filter will permit the packet and take no additional action.
The filter will reject the packet and send an ICMP message back to the sender.
The filter will discard the packet and take no additional action.
The filter will permit the packet and write a log entry to the firewall log.
第11题:
The source device will only retransmit lost packets on the request of the destination device.
The source device starts a timer when it sends a segment and retransmits if an acknowledgment is not received before the timer expires.
The destination device acknowledges receipt of a segment by sending a packet with a new sequence number and the ACK bit sent.
The destination device acknowledges receipt of a segment by sending a packet that indicates the next sequence number it expects.
If the destination device does not receive a segment, all segments are retransmitted.
The source device keeps a record of all segments sent and expects and acknowledgment of each.
第12题:
The FWSM supports up to 16 asymmetric routing groups.
If a matching packet is not found, the packet is dropped.
Asymetric routing of return traffic is enabled.
If a matching packet is found, the Layer 3 header is rewritten.
If a matching packet is found, the Layer 3 header is rewritten and the packet is forwarded to the default gateway.

The Junos OS performs policy lookup only for the first packet of a flow.
The Junos OS applies SCREEN options for both first and consecutive packets of a flow.
第19题:
It is a route to be used when the routing protocol fails.
It is a route configured by an ISP that sends traffic into a corporate network.
It is a route used when a packet is destined for a remote network that is not listed in the routing table.
It is a route manually configured for a specific remote network for which a routing protocol is not configured.
It is used to send traffic to a stub network.
第20题:
The PFE floods the packet out of all interfaces.
The PFE drops the packet and sends a destination unreachable notification back to source device.
The PFE forwards the packet to the routing engine for furtherprocessing.
The PFE queues the packet and sends are quest for a layer3 lookup to the routing engine.
