Q663. IP Connectivity
Which two outcomes are predictable behaviors for HSRP? (Choose two)
Choose 2 — select all that apply
AThe two routers share a virtual IP address that is used as the default gateway for devices on the LAN.
BThe two routers negotiate one router as the active router and the other as the standby router.
CEach router has a different IP address both routers act as the default gateway on the LAN, and traffic is load balanced between them. D. The two routers synchronize configurations to provide consistent packet forwarding.
EThe two routed share the same IP address, and default gateway traffic is load-balanced between them.
Correct Answer:AB
Q671. Network Fundamentals
Which action is taken by a switch port enabled for PoE power classification override?
AWhen a powered device begins drawing power from a PoE switch port a syslog message is generated.
BAs power usage on a PoE switch port is checked data flow to the connected device is temporarily paused.
CIf a switch determines that a device is using less than the minimum configured power it assumes the device has failed and disconnects.
DIf a monitored port exceeds the maximum administrative value for power, the port is shutdown and errdisabled.
Correct Answer:D
Explanation: PoE monitoring and policing compares the power consumption on ports with the administrative maximum value (either a configured maximum value or the port’s default value). If the power consumption on a monitored port exceeds the administrative maximum value, the following actions occur: – A syslog message is issued. – The monitored port is shut down and error-disabled. – The allocated power is freed.

Q681. Network Fundamentals
Which 802.11 frame type is association response?
Amanagement
Bprotected frame
Ccontrol
Daction
Correct Answer:A
There are three main types of 802.11 frames: the Data Frame, the Management Frame and the Control Frame. Association Response belongs to Management Frame. Association response is sent in response to an association request. Reference: https://en.wikipedia.org/wiki/802.11_Frame_Types
Q694. IP Services
Which two tasks must be performed to configure NTP to a trusted server in client mode on a single network device? (Choose two) A. Enable NTP authentication.
Choose 2 — select all that apply
BVerify the time zone.
CDisable NTP broadcasts.
DSpecify the IP address of the NTP server.
ESet the NTP server private key.
Correct Answer:AD
To configure authentication, perform this task in privileged mode: Step 1: Configure an authentication key pair for NTP and specify whether the key will be trusted or untrusted. Step 2: Set the IP address of the NTP server and the public key. Step 3: Enable NTP client mode. Step 4: Enable NTP authentication. Step 5: Verify the NTP configuration. Reference: Click here
Q703. IP Connectivity
Refer to the exhibit. The New York router is configured with static routes pointing to the Atlanta and Washington sites. Which two tasks must be performed so that the Serial0/0/0 interfaces on the Atlanta and Washington routers can reach one another? (Choose two.)
Choose 2 — select all that apply
AConfigure the ipv6 route 2012::/126 2023::1 command on the Washington router.
BConfigure the ipv6 route 2023::/126 2012::1 command on the Atlanta router.
CConfigure the Ipv6 route 2012::/126 s0/0/0 command on the Atlanta router.
DConfigure the ipv6 route 2023::/126 2012::2 command on the Atlanta router.
EConfigure the ipv6 route 2012::/126 2023::2 command on the Washington router.
Correct Answer:DE
The short syntax of static IPv6 route is: ipv6 route <destination-IPv6-address> {next-hop-IPv6-address | exit-interface}
Q712. Network Access
Which result occurs when PortFast is enabled on an interface that is connected to another switch?
ASpanning tree may fail to detect a switching loop in the network that causes broadcast storms.
BVTP is allowed to propagate VLAN configuration information from switch to switch automatically.
CRoot port choice and spanning tree recalculation are accelerated when a switch link goes down.
DAfter spanning tree converges PortFast shuts down any port that receives BPDUS.
Correct Answer:A
Enabling the PortFast feature causes a switch or a trunk port to enter the STP forwarding-state immediately or upon a linkup event, thus bypassing the listening and learning states. Note: To enable portfast on a trunk port you need the trunk keyword "spanning-tree portfast trunk"
Q721. Network Fundamentals
Refer to exhibit. Which statement explains the configuration error message that is received?
AIt is a broadcast IP address.
BThe router does not support/28 mask.
CIt belongs to a private IP address range.
DIt is a network IP address.
Correct Answer:A
Q733. IP Connectivity
When a floating static route is configured, which action ensures that the backup route is used when the primary route fails?
AThe floating static route must have a higher administrative distance than the primary route so it is used as a backup.
BThe administrative distance must be higher on the primary route so that the backup route becomes secondary
CThe floating static route must have a lower administrative distance than the primary route so it is used as a backup.
DThe default-information originate command must be configured for the route to be installed into the routing table.
Correct Answer:A

Q751. Network Fundamentals
Which network allows devices to communicate without the need to access the Internet?
A172.9.0.0/16
B172.28.0.0/16
C192.0.0.0/8
D209.165.201.0/24
Correct Answer:B
This question asks about the private ranges of IPv4 addresses. The private ranges of each class of IPv4 are listed below: Class A private IP address ranges from 10.0.0.0 to 10.255.255.255 Class B private IP address ranges from 172.16.0.0 to 172.31.255.255 Class C private IP address ranges from 192.168.0.0 to 192.168.255.255 Only the network 172.28.0.0/16 belongs to the private IP address (of class B).
