What is the main purpose of DHCP?
The main purpose of DHCP is to provide network security protocols.
The main purpose of DHCP is to manage network traffic efficiently.
The main purpose of DHCP is to assign static IP addresses to servers.
The main purpose of DHCP is to dynamically assign IP addresses to devices on a network.
How does a device get an IP address from DHCP?
A device gets an IP address from DHCP through a process of discovery, offer, request, and acknowledgment.
A device obtains an IP address from DHCP through a manual setup by the user.
A device receives an IP address from DHCP via a static configuration process.
A device acquires an IP address from DHCP using a direct connection to the router.
What is a DHCP server?
A DHCP server is a firewall that protects network devices.
A DHCP server is a router that connects different networks.
A DHCP server is a network server that automatically assigns IP addresses to devices on a network.
A DHCP server is a device that monitors network traffic.
What is a DHCP lease?
A DHCP lease is a permanent allocation of an IP address to a device.
A DHCP lease is a protocol for managing network security settings.
A DHCP lease is a method for assigning static IP addresses to devices.
A DHCP lease is a temporary assignment of an IP address to a device by a DHCP server.
What happens when a DHCP lease expires?
The client must renew the lease or request a new IP address.
The lease is extended without any action needed.
The client automatically receives a new IP address.
The device loses network connectivity immediately.
Can DHCP assign static IP addresses?
Yes, DHCP can assign static IP addresses through DHCP reservation.
No, static IPs must be manually configured.
Yes, but only for devices that are offline.
No, DHCP only assigns dynamic IP addresses.
What is the difference between DHCP and static IP?
DHCP uses fixed IP addresses, while static IPs are assigned automatically.
Static IP addresses are assigned by a server, while DHCP is manual.
DHCP requires user input for every IP assignment, unlike static IPs.
DHCP assigns IP addresses dynamically, while static IP addresses are fixed and manually assigned.
What is a DHCP client?
A DHCP client is a server that assigns IP addresses to devices.
A DHCP client is a protocol for managing network security.
A DHCP client is a software that monitors network traffic.
A DHCP client is a device that requests IP address and network configuration from a DHCP server.
Why is DHCP important for networks?
DHCP is important because it provides a backup for all network configurations and settings.
DHCP is crucial for enhancing network security and preventing unauthorized access.
DHCP is essential for ensuring all devices have static IP addresses for better performance.
DHCP is important because it automates IP address assignment, reduces conflicts, and simplifies network management.
Which version of SSH should be enabled for maximum security?
v1
v2
both v1 and v2
v3
Which command generates RSA keys for SSH?
crypto key generate dsa
ip ssh rsa-generate
crypto key generate rsa
ssh keygen rsa
What ACL type filters traffic based on source IP only?
Standard ACL
Extended ACL
Named ACL
IPv6 ACL
Which port does SSH use by default?
22
23
80
443
What command applies an ACL inbound on an interface?
ip access-list inbound
access-class
ip access-group [number] in
apply acl in
Which command secures console access with a password?
enable secret
username console password
line con 0 → password [value]
set console pass
Which encryption type is strongest for user passwords in Cisco IOS?
Type 0
Type 4
Type 5
Type 9
What does the command “login local” do?
Uses VTY password
Uses console password
Uses local username database
Bypasses login
Which ACL range defines extended ACLs?
1–99
100–199
200–299
1000–1999
Which command forces password encryption for plaintext passwords?
enable password encrypt
service password-encryption
password secure mode
encrypt passwords
You configure a static route on Router R1:
ip route 10.10.0.0 255.255.0.0 192.168.1.2
But R1 still does not forward traffic to 10.10.0.0/16. Why?
The next-hop must be directly connected
An exit interface must be configured
R1 has no route to reach 192.168.1.2
The subnet mask is invalid
A router has multiple static routes to the same destination with different next hops. Which factor determines which route is installed in the routing table?
Route metric
Administrative distance
Lowest outgoing interface number
Hop count
A floating static route is primarily used to:
Reduce routing table size
Load-balance traffic
Provide backup routing when dynamic routing fails
Improve CPU efficiency
On Cisco devices, which command verifies whether a static route is active in the routing table?
show ip protocols
show ip static routes
show run | include route
show ip route
You configure two static routes to 0.0.0.0/0:
ip route 0.0.0.0 0.0.0.0 10.1.1.1
ip route 0.0.0.0 0.0.0.0 10.2.2.2 200
Load balancing occurs across both next-hops
Only the second route is installed
The first route is primary; the second is backup
Neither route is installed
Which static route type can cause routing loops if misconfigured?
Fully specified static route
Recursive static route
Directly connected static route
Default static route
A static route configured with an exit interface on a multi-access network can cause:
Faster convergence
ARP broadcast storms
Automatic load balancing
Higher AD values
Which of the following longest-prefix matches takes priority in routing?
10.0.0.0/8
10.10.0.0/16
10.10.20.0/24
10.10.20.128/25
A static route exists on R1 pointing to R2, but R2 has no route back to R1. What will occur?
Traffic will successfully flow both directions
R1 drops outbound traffic
Return traffic is dropped (asymmetric routing issue)
R2 automatically generates a reverse route
Which scenario requires a fully specified static route?
Point-to-point link
Multi-access network where next-hop ambiguity exists
Stub network
Default routing configuration
How many ICT staff all teachers are there in GSP?
