Cisco 1 2022 Final Difficult Questions

Which destination address is used in an ARP request frame? - 01-00-5E-00-AA-23 - FFFF.FFFF.FFFF - 127.0.0.1 - 0.0.0.0 - 255.255.255.255

- FFFF.FFFF.FFFF The purpose of an ARP request is to find the MAC address of the destination host on an Ethernet LAN. The ARP process sends a Layer 2 broadcast to all devices on the Ethernet LAN. The frame contains the IP address of the destination and the broadcast MAC address, FFFF.FFFF.FFFF

An administrator is configuring a new router to permit out-of-band management access. Which set of commands will allow the required login using a password of cisco? (pick 3 or more) - Line Console 0 - Line vty 0 4 - password cisco - login - exit - service password-encryption - enable password cisco

- Line Console 0 - Password Cisco - login

T/F? The subnet ID field in a GUA must borrow bits from the interface ID

False

How does the ARP process use an IPv4 address? - to determine the amount of time a packet takes when traveling from source to destination - to determine the MAC address of the remote destination host - to determine the network number based on the number of bits in the IPv4 address - to determine the MAC address of a device on the same network

to determine the MAC address of a device on the same network The ARP process is used to complete the necessary mapping of IPv4 and MAC addresses that are stored in the ARP table that is maintained by each node on a LAN. When the destination device is not on the same network as the source device, the MAC address of the Layer 3 device on the source network is discovered and added to the ARP table of the source node

Which two situations are the result of excessive broadcast traffic? (choose two) - Slow network operations - Slow device operations - when devices are on all adjacent networks are affected - when the router has to forward an excessive number of packets

- Slow network operations - slow device operations

T/F: 4/5 RIRs no longer have enough IPv4 addresses to allocate to customers on a regular basis

false

Which two statements are correct about private IPv4 addresses? - Private IPv4 addresses are assigned to devices within an organizations intranet (internal network) - Internet routers will typically forward any packet with a destination address that is a private IPv4 address - 172.99.1.1 is a private IPv4 address - Any organization (home, school, office, company) can use the 10.0.0.0/8 address

- Private IPv4 addresses are assigned to devices within an organization's intranet - Any organization can use the 10.0.0.0/8 address

A PC is configured to obtain an IPv4 address automatically from network 192.168.1.0/24. The network administrator issues the arp -a command and notices an entry of 192.168.1.255 ff-ff-ff-ff-ff-ff. Which statement describes this entry? - This entry refers to the PC itself. - This is a static map entry. - This is a dynamic map entry. - This entry maps to the default gateway.

- This is a static map entry. The IPv4 address of 192.168.1.255 on 192.168.1.0/24 network is the broadcast address, which is statically mapped to ff-ff-ff-ff-ff-ff in the ARP table

What two protocols are used to determine the MAC address of a known destination device IP address (IPv4 and IPv6)? DHCP ARP DNS ND

ARP, ND Address Resolution Protocol(ARP) is used to determine the device MAC address of a known destination device IPv4 address. Neighbor Discovery(ND) is used to determine the MAC address of a known destination

What two methods a device can use to generate its own IPv6 interface ID? pick two SLAAC Stateless DHCPv6 stateful DHCPv6 EUI-64 randomly generated

EUI-64 randomly generated

Which part of a GUA is assigned by the ISP? Global routing prefix Global routing prefix and subnet ID Prefix RIR prefix

Global routing prefix

Which dynamic addressing method for GUAs is the one where devices rely solely on the contents of the RA message for their addressing information? Method 1: SLAAC Method 2: SLAAC and stateless DHCPv6 Method 3: Stateful DHCPv6

Method 1: SLAAC

Which dynamic addressing method for GUAs is the one where devices get their IPv6 configuration in a RA message and request DNS information from a DHCPv6 server? Method 1: SLAAC Method 2: SLAAC and stateless DHCPv6 Method 3: Stateful DHCPv6

Method 2: SLAAC and stateless DHCPv6

Which dynamic addressing method for GUAs is the one where devices rely solely on a DHCPv6 server for their addressing information? Method 1: SLAAC Method 2: SLAAC and stateless DHCPv6 Method 3: Stateful DHCPv6

Method 3: Statefull DHCPv6

Which two ICMPv6 messages are used in to determine the MAC address of a known IPv6 address? Router Advertisement Neighbor Advertisement Router Solicitation Neighbor Solicitation

Neighbor Advertisement Neighbor Solicitation

Which CLI mode allows users to access all device commands, such as those used for configuration, management, and troubleshooting? - Global configuration mode - Privileged EXEC mode - Interface configuration mode User EXEC mode

Priviledged EXEC mode The command "Router#configure terminal" allows a user to enter privileged mode from where the configuration, management, and troubleshooting commands can also be accessed

Where is the ARP table stored on a device? ROM flash NVRAM RAM

RAM The ARP table is cached temporarily in RAM

Which organization or group of organizations receives IP addresses from IANA and is responsible for allocating these addresses to ISPs and some organizations? - IETF - IEEE - RIRs - Tier 1 ISPs

RIRs

Which two ICMPv6 messages are used in SLAAC? Router Advertisement Neighbor Advertisement Router Solicitation Neighbor Solicitation
