Q:41-60 Flashcards
- Refer to the exhibit. What can be concluded about the configuration shown on R1?
R1 is configured as a DHCPv4 relay agent.
R1 is operating as a DHCPv4 server.
R1 will broadcast DHCPv4 requests on behalf of local DHCPv4 clients.
R1 will send a message to a local DHCPv4 client to contact a DHCPv4 server at 10.10.10.8.
R1 is configured as a DHCPv4 relay agent.
- Match the step to each switch boot sequence description. (Not all options are used.)
- Refer to the exhibit. R1 has been configured as shown. However, PC1 is not able to receive an IPv4 address. What is the problem?
The ip helper-address command was applied on the wrong interface.
R1 is not configured as a DHCPv4 server.
A DHCP server must be installed on the same LAN as the host that is receiving the IP address.
The ip address dhcp command was not issued on the interface Gi0/1.
The ip helper-address command was applied on the wrong interface.
- What two default wireless router settings can affect network security? (Choose two.)
The SSID is broadcast.
MAC address filtering is enabled.
WEP encryption is enabled.
The wireless channel is automatically selected.
A well-known administrator password is set.
The SSID is broadcast.
A well-known administrator password is set.
- What is the common term given to SNMP log messages that are generated by network devices and sent to the SNMP server?
traps
acknowledgments
auditing
warnings
traps
- A network administrator is adding a new WLAN on a Cisco 3500 series WLC. Which tab should the administrator use to create a new VLAN interface to be used for the new WLAN?
WIRELESS
MANAGEMENT
CONTROLLER
WLANs
CONTROLLER
- A network administrator is configuring a WLAN. Why would the administrator change the default DHCP IPv4 addresses on an AP?
to restrict access to the WLAN by authorized, authenticated users only
to monitor the operation of the wireless network
to reduce outsiders intercepting data or accessing the wireless network by using a well-known address range
to reduce the risk of interference by external devices such as microwave ovens
to reduce outsiders intercepting data or accessing the wireless network by using a well-known address range
- Which two functions are performed by a WLC when using split media access control (MAC)? (Choose two.)
packet acknowledgments and retransmissions
frame queuing and packet prioritization
beacons and probe responses
frame translation to other protocols
association and re-association of roaming clients
frame translation to other protocols
association and re-association of roaming clients
- On what switch ports should BPDU guard be enabled to enhance STP stability?
all PortFast-enabled ports
only ports that are elected as designated ports
only ports that attach to a neighboring switch
all trunk ports that are not root ports
all PortFast-enabled ports
- Which network attack is mitigated by enabling BPDU guard?
rogue switches on a network
CAM table overflow attacks
MAC address spoofing
rogue DHCP servers on a network
rogue switches on a network
- Why is DHCP snooping required when using the Dynamic ARP Inspection feature?
It relies on the settings of trusted and untrusted ports set by DHCP snooping.
It uses the MAC address table to verify the default gateway IP address.
It redirects ARP requests to the DHCP server for verification.
It uses the MAC-address-to-IP-address binding database to validate an ARP packet.
It uses the MAC-address-to-IP-address binding database to validate an ARP packet.
- Refer to the exhibit. Router R1 has an OSPF neighbor relationship with the ISP router over the 192.168.0.32 network. The 192.168.0.36 network link should serve as a backup when the OSPF link goes down. The floating static route command ip route 0.0.0.0 0.0.0.0 S0/0/1 100 was issued on R1 and now traffic is using the backup link even when the OSPF link is up and functioning. Which change should be made to the static route command so that traffic will only use the OSPF link when it is up?
Change the administrative distance to 120.
Add the next hop neighbor address of 192.168.0.36.
Change the destination network to 192.168.0.34.
Change the administrative distance to 1.
Change the administrative distance to 120.
- Refer to the exhibit. What is the metric to forward a data packet with the IPv6 destination address 2001:DB8:ACAD:E:240:BFF:FED4:9DD2?
90 128 2170112 2681856 2682112 3193856
2682112
- A network administrator is configuring a new Cisco switch for remote management access. Which three items must be configured on the switch for the task? (Choose three.)
IP address VTP domain vty lines default VLAN default gateway loopback address
IP address
vty lines
default gateway
- Refer to the exhibit. Which statement shown in the output allows router R1 to respond to stateless DHCPv6 requests?
ipv6 nd other-config-flag
prefix-delegation 2001:DB8:8::/48 00030001000E84244E70
ipv6 dhcp server LAN1
ipv6 unicast-routing
