An engineer is configuring a GRE tunnel interface in the default mode. The engineer has assigned an IPv4 address on the tunnel and sourced the tunnel from an Ethernet interface.
Which option also is required on the tunnel interface before it is operational?
A. tunnel destination address
C. IPv6 address
D. tunnel protection
What is the function of the snmp-server manager command?
A. To enable the device to send and receive SNMP requests and responses
B. To enable the device to send SNMP traps to the SNMP server
C. To disable SNMP messages from getting to the SNMP engine
D. To configure the SNMP server to store log data
The SNMP manager process sends SNMP requests to agents and receives SNMP responses and notifications from agents. http://www.cisco.com/c/en/us/td/docs/ios/12_2/configfun/command/reference/ffun_r/frf014.html#wp1022914
Which switching method is used when entries are present in the output of the command show ip cache?
A. fast switching
B. process switching
C. Cisco Express Forwarding switching
D. cut-through packet switching
Fast switching allows higher throughput by switching a packet using a cache created by the initial packet sent to a particular destination. Destination addresses are stored in the high-speed cache to expedite forwarding. Routers offer better packet-transfer performance when fast switching is enabled. Fast switching is enabled by default on all interfaces that support fast switching. To display the routing table cache used to fast switch IP traffic, use the “show ip cache” EXEC command.

Refer in the exhibit. A packet capture indicates that the router is not forwarding the DHCP packets that it receives on interface FastEthernet0/0.
Which command needs to be entered in global configuration mode to resolve this issue?
A. ip helper-address
B. ip DHCP relay
C. service DHCP
D. ip forward-protocol
A network engineer applies the command ip tcp adjust-mss <bytes> under interface configuration mode.
What is the result?
A. The probability of SYN packet truncation is increased.
B. The UDP session is inversely affected.
C. The probability of dropped or segmented TCP packets is decreased.
D. The optimum MTU value for the interface is set.
which two statement about GRE tunnel interface are true? (choose two)
A. A tunnel can be established when a source the source interface is in the up/down state
B. A tunnel Destination must be Routable, but it can be unreachable
C. To establish a tunnel the source interface must be a loopback
D. To Establish a tunnel the source interface must be up/up state
E. A tunnel destination must be a physical interface that is on up/up state
