Which WAN topology has the highest degree of reliability?
The correct answer is C. Option C: full mesh
What causes a port to be placed in the err-disabled state?
The correct answer is B. Option B: link flapping
A network engineer must configure an interface with IP address 10.10.10.145 and a subnet mask equivalent to 11111111.11111111.11111111.11111000. Which subnet mask must the engineer use?
The correct answer is A. Option A: /29
Refer to the exhibit. The switches are connected via a Cat5 Ethernet cable that is tested successfully. The interfaces are configured as access ports and are both in a down status. What is the cause of the issue?
The correct answer is A. Option A: The speed settings on the switches are mismatched
Which two IP addressing schemes provide internet access to users on the network while preserving the public IPv4 address space? (Choose two.)
The correct answer is A, B. Option A: IPv6 addressing Option B: PAT with private internal addressing
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. IPv6 uses 128-bit addresses and relies on Neighbor Discovery rather than ARP. PAT distinguishes many inside sessions on one public address by translating transport-layer ports.
The address block 192.168.32.0/24 must be subnetted into smaller networks. The engineer must meet these requirements: • Create 8 new subnets. • Each subnet must accommodate 30 hosts. • Interface VLAN 10 must use the last usable IP in the first new subnet. • A Layer 3 interface is used. Which configuration must be applied to the interface?
The correct answer is C. Option C: no switchport ip address 192.168.32.30 255.255.255.224
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead.
What are two reasons to deploy private addressing on a network? (Choose two.)
The correct answer is B, C. Option B: to reduce network maintenance costs Option C: to segment local IP addresses from the global routing table
Explanation
OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. This option keeps traffic private / properly secured as required.
Which property is shared by 10GBase-SR and 10GBase-LR interfaces?
The correct answer is C. Option C: Both require fiber cable media for transmission.
Which device permits or denies network traffic based on a set of rules?
The correct answer is B. Option B: firewall
What is the role of a firewall in an enterprise network?
The correct answer is A. Option A: determines which packets are allowed to cross from unsecured to secured networks
Refer to the exhibit. An IP subnet must be configured on each router that provides enough addresses for the number of assigned hosts and anticipates no more than 10% growth for new hosts. Which configuration script must be used? A. B. C. D.
The correct answer is C. Option C:
Which action is taken by a switch port enabled for PoE power classification override?
The correct answer is D. Option D: Should a monitored port exceed the maximum administrative value for power, the port is shut down and err-disabled
What is a function spine-and-leaf architecture?
The correct answer is A. Option A: Offers predictable latency of the traffic path between end devices.
Explanation
PAT distinguishes many inside sessions on one public address by translating transport-layer ports.
Which action is taken by the data plane within a network device?
The correct answer is B. Option B: Forwards traffic to the next hop.
What is the function of the control plane?
The correct answer is A. Option A: It exchanges routing table information.
Which two cable types must be used to connect an access point to the WLC when 2.5-Gbps and 5-Gbps upload speeds are required? (Choose two.)
The correct answer is A, C. Option A: 10GBASE-T Option C: Cat 5e
What is a benefit for external users who consume public cloud resources?
The correct answer is C. Option C: Accessed over the Internet
An engineer must update the configuration on two PCs in two different subnets to communicate locally with each other. One PC is configured with IP address 192.168.25.128/25 and the other with 192.168.25.100/25. Which network mask must the engineer configure on both PCs to enable the communication?
The correct answer is C. Option C: 255.255.255.0
Which key function is provided by the data plane?
The correct answer is D. Option D: Forwarding traffic to the next hop
When should an engineer implement a collapsed-core architecture?
The correct answer is B. Option B: For small networks with minimal need for growth
