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.)
- A. 10GBASE-T
- B. 1000BASE-LX/LH
- C. Cat 5e
- D. Cat 5
- E. Cat 3
What is a benefit for external users who consume public cloud resources?
- A. Implemented over a dedicated WAN
- B. All hosted on physical servers
- C. Accessed over the Internet
- D. Located in the same data center as the users
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?
- A. 255.255.255.248
- B. 255.255.255.224
- C. 255.255.255.0
- D. 255.255.255.252
Which key function is provided by the data plane?
- A. Originating packets
- B. Exchanging routing table data
- C. Making routing decisions
- D. Forwarding traffic to the next hop
When should an engineer implement a collapsed-core architecture?
- A. Only when using VSS technology
- B. For small networks with minimal need for growth
- C. For large networks that are connected to multiple remote sites
- D. The access and distribution layers must be on the same device
Refer to the exhibit. An engineer assigns IP addressing to the current VLAN with three PCs. The configuration must also account for the expansion of 30 additional
VLANS using the same Class C subnet for subnetting and host count. Which command set fulfills the request while reserving address space for the expected growth?
- A. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 265 255.255.252
- B. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 255 255.255.248
- C. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 255 255.255.0
- D. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 255.255.255.128
A client experiences slow throughput from a server that is directly connected to the core switch in a data center. A network engineer finds minimal latency on connections to the server, but data transfers are unreliable, and the output of the show interfaces counters errors command shows a high FCS-Err count on the interface that is connected to the server. What is the cause of the throughput issue?
- A. a physical cable fault
- B. a speed mismatch
- C. high bandwidth usage
- D. a cable that is too long
What is the difference between 1000BASE-LX/LH and 1000BASE-ZX interfaces?
- A. 1000BASE-LX/LH interoperates with multimode and single-mode fiber, and 1000BASE-ZX needs a conditioning patch cable with multimode.
- B. 1000BASE-ZX interoperates with dual-rate 100M/1G 10Km SFP over multimode fiber, and 1000BASE-LX/LH supports only single-rate
- C. 1000BASE-ZX is supported on links up to 1000km, and 1000BASE-LX/LH operates over links up to 70 km
- D. 1000BASE- LX/LH is supported on links up to 10km, and 1000Base-ZX operates over links up to 70 km
What are two reasons to implement IPv4 private addressing on a network? (Choose two.)
- A. To enable internal applications to treat the private IPv4 addresses as unique
- B. To facilitate renumbering when merging networks
- C. To expand the routing table on the router
- D. To provide protection from external denial-of-service attacks
- E. To conserve global unique IPv4 addresses
Which concern is addressed with the use of private IPv4 addressing?
- A. Lack of routing protocol support for CIDR and VLSM
- B. Lack of security protocols at the network perimeter
- C. Lack of available TCP/UDP ports per IPv5 address
- D. Lack of available publicly routable unique IPv4 address
