Network: 172.16.10.128, Broadcast: 172.16.10.255
Network: 172.16.10.0, Broadcast: 172.16.10.127
Network: 172.16.10.128, Broadcast: 172.16.10.191
Network: 172.16.10.0, Broadcast: 172.16.10.255
Which of the following best describes the primary purpose of a VLAN?
To encrypt data between two devices
To logically separate networks without additional physical switches
To increase wireless bandwidth
To replace the need for routing protocols
Which of the following characteristics belong to UDP? (Select TWO)
Connectionless communication
Reliable delivery with acknowledgments
Low overhead and faster performance
Three-way handshake before data transfer
Arrange the following DHCP steps in the correct order: DHCP Offer, DHCP Ack, DHCP Discover, DHCP Request
3 → 1 → 4 → 2
1 → 3 → 2 → 4
3 → 4 → 1 → 2
2 → 3 → 1 → 4
Which of the following scenarios would be the best use of a DHCP reservation?
Assigning IP addresses to mobile phones that change networks often
Ensuring a network printer always receives the same IP address
Preventing a group of addresses from being used by DHCP
Allowing devices to self-assign IPs when no DHCP is available
A technician notices a workstation has an IP address of 169.254.100.5. What does this most likely indicate?
The device is using SLAAC for IPv6 addressing
The device is configured with a static IP
The device could not contact a DHCP server
The device has duplicate IP detection enabled
Which of the following statements are true about SLAAC? (Select TWO)
It requires a DHCPv6 server to function
It generates IPv6 addresses using EUI-64
It supports Duplicate Address Detection (DAD)
It provides DNS server information automatically
Which of the following are advantages of using DHCPv6 compared to SLAAC?
Centralized control of address assignments
Simpler configuration with no need for servers
Ability to assign additional configuration such as DNS
Works only with IPv4 networks
A user reports they cannot access the internet. You run ipconfig and see the workstation has an IP address of 169.254.55.22 with no default gateway listed. What is the most likely issue?
The DNS server is unreachable
The DHCP server did not assign an IP address
The workstation has a duplicate IP conflict
The NIC is disabled
A Linux administrator runs ip addr on a server and notices the eth0 interface is down. Which command should they run to bring the interface online?
ip addr add eth0 up
ip link set eth0 up
ip route add eth0 enable
ifconfig eth0 -enable
A technician is troubleshooting network connectivity. They suspect a static ARP entry is causing incorrect routing. Which command would remove all entries from the ARP cache?
arp –a
arp –d
arp –s
arp –flush
You are configuring a new IPv6 host. The address begins with fe80::/10. Which of the following best describes this type of address?
A globally routable IPv6 address
A link-local address used for communication within a subnet
A multicast address used for one-to-many communication
A transition address for NAT64
A technician attempts to ping a remote server. The response is “Destination host unreachable.” What does this most likely indicate?
The remote host is powered off
A routing or gateway issue is preventing communication
The network cable is unplugged
ICMP is blocked by a firewall on the server
An organization is deploying IPv6 but must continue supporting IPv4-only applications. Which transition mechanism allows IPv6 packets to travel across an IPv4-only network?
Dual Stack
NAT64
SLAAC
Tunneling
Your company runs both IPv4 and IPv6 simultaneously during migration. Which method is being used?
NAT64
Dual Stack
6to4 Tunneling
SLAAC
Which of the following is a key advantage of dynamic routing over static routing?
Less memory usage on routers
Greater administrative control of each route
Adapts automatically to network changes
No configuration required on any device
Which of the following are common types of entries found in a routing table? (Select TWO)
Directly connected routes
Default routes
VLAN membership routes
DNS cache entries
A small organization is using the RIP protocol. Which limitation makes RIP unsuitable for large networks?
It only supports IPv6
Maximum hop count of 15
It does not use routing tables
It requires proprietary Cisco hardware
Which of the following best describes EIGRP?
A link-state protocol that uses Dijkstra’s algorithm
A legacy distance-vector protocol that only uses hop count
A Cisco-proprietary protocol using multiple metrics like bandwidth and delay
A gateway protocol used for routing between autonomous systems
Which of the following are characteristics of OSPF? (Select TWO)
Uses the shortest path first algorithm
Limited to 15 hops
More efficient in small, stable networks
Supports complex topologies within an autonomous system
Which statement best describes the role of Border Gateway Protocol (BGP)?
It finds the shortest path within a single organization’s network
It is a gateway protocol that exchanges routing information between autonomous systems
It is a Cisco-proprietary protocol for IPv4 and IPv6 routing
It only functions in small enterprise networks
Which of the following are features of a stateful firewall compared to a stateless firewall? (Select TWO)
Operates at the network layer only
Tracks the state of active connections
Filters only on IP addresses and port numbers
Provides stronger protection for corporate environments
How many bits are in an ipv4 address?
16
32
64
128
What is the default subent mask for the Class C network?
255.255.254.0
