Your colleague is new to networking and asks you about network devices. Which statements below would help your colleague understand this topic? (Select two.). a. You use switches to connect many end systems together, at layer 3 of the OSI model. b. Routers are often used in WAN environments, and forward packets based on IP address information. c. Multi-layer switches perform functions of a firewall and a router. d. Stateful firewalls have more intelligence than stateless firewalls, perhaps including application awareness features.

Which statements below accurately describe initial switch access and setup? (Select two.). a. You can make an out-of-band management (OOBM) connection to a switch using a serial connection. b. One advantage of making an out-of-band management (OOBM) connection to a switch using the management port is that it enhances redundancy for your data traffic. c. One advantage of making an out-of-band management (OOBM) connection to a switch using the management port is that it can mitigate bad actors trying to gain access to your switches. d. You connect to a switch via the console port, but you must configure that port with an IP address.

How would you properly identify the port indicated in Figure?. a. interface 1/48. b. interface 1/1/48. c. interface 48/1/1. d. interface 1/48/1.

When entering command line interface (CLI) commands on a switch, why might you use the <Tab> key?. a. To move up one level in the CLI prompt mode hierarchy. b. To access the context-sensitive help feature. c. To exit out of global configuration mode. d. To complete a CLI command that is partially entered.

Your colleague asks you about managing configuration files on an AOS-CX switch. Which statements below would improve their understanding? (Select three.). a. The running-config is stored in RAM. b. The startup-config is stored in flash memory. c. When the switch reboots, unsaved changes to the startupconfig are lost. d. AOS-CX considers both the startup-config and the running-config configurations to be “checkpoints”.

Which of the options below are advantages of Virtual LANs (VLANs) as compared to physical LANs? (Select two.). a. VLANs segment the broadcast domain to improve performance. b. VLANs are more scalable. c. Routing between VLANs does not require a router. d. Multiple VLANs can be defined on a single switch.

You use trunk ports to extend the range of VLANs supported on a switch. a. True. b. False.

Which of the following are true about the Link Layer Discover Protocol (LLDP)? (Select two.). a. It helps you discover, document, and troubleshoot networks. b. LLDP has a Media Endpoint Discovery (MED) enhancement to help with “plug-and-play” networking. c. LLDP operates at Layers 2 and 3 of the OSI model. d. LLDP is enabled by default on both Aruba AOS-CX switches and Aruba Mobility gateways.

Choose the options below that accurately describe link aggregation. (Select three.). a. It enhances both performance and reliability. b. Member ports in a LAG should have matching duplex, speed, and media for their connected ports. c. A static LAG configuration is preferred over other methods, due to its simplicity. d. Peers that use the LACP can automatically form a LAG between them.

Given the IP address 172.16.3.42, and a subnet mask of 255.255.255.0, what is the host portion of the address? (Fill in the blank.) ____________________________.

Match the TCP/IP stack layer to an appropriate description: Switching Port. Switch Virtual Interface (SVI). Routing Port.

Refer to the diagram in Figure. Server-1’s ping packet reaches Server-2. However, Server-2’s reply packet does not reach Server-1. Which of the options below is a likely cause of this issue? (Select two.). a. Server-1’s default-gateway is not properly configured. b. Server-2’s default-gateway is not properly configured. c. Core-1 has a route to reach Server-2 but lacks a return path to Server-1. d. Core-2 has a route to reach Server-2 but lacks a return path to Server-1.

Refer to the diagram in Figure. On router Core-1, your colleague has entered the command ip route 10.1.20.0/24 10.1.12.2. Which of the following options might you use to discuss this situation with your colleague?. a. It appears that Core-1 will be able to route packets to subnet 10.1.20.0, which uses a mask of 255.255.224.0. b. If devices on subnets 10.1.10.0/24 and 10.1.20.024 cannot communicate, it might be because you specified an incorrect next-hop route. c. If devices on subnets 10.1.10.0/24 and 10.1.20.024 cannot communicate, it might be because you need to configure a return path on Core-2. d. It appears that host 10.1.12.2 will be able to reach devices on subnet 10.1.10.0/24.

5. Which statements below are true about the Open Shortest Path First (OSPF) routing protocol? (Select two.). a. It is more scalable than RIP. b. For simplicity, it is best to let the router choose its own router ID (RID). c. You can leverage loopback interfaces to enhance OSPF stability. d. If you do not configure a router ID (RID), the OSPF router prefers to use the numerically highest IPv4 address assigned to a loopback interface.

Match an appropriate description to each of the OSPF entities below (neighbor table, topology database, routing table). neighbor table. topology database. routing table.
