HPE6-A85 HPE Network Campus Access Associate Practice Questions

In Rapid Spanning Tree Protocol (RSTP), an 'Alternate' port is a port that provides a redundant, secondary path toward the root bridge. It is currently in a discarding (blocking) state to prevent a loop but is ready to transition immediately to a forwarding state if the primary path (the Root Port) fails. This is a key enhancement of RSTP over legacy STP for faster convergence.

To prioritize traffic from a specific VLAN, the first step is to classify it. An administrator would create a policy that identifies traffic belonging to VLAN 50. Then, that traffic would be marked with a higher priority value (e.g., a specific CoS or DSCP value). Subsequent queuing mechanisms on the switch will then use this marking to give the SCADA traffic preferential treatment over the lower-priority data traffic, especially during periods of congestion.

The problem describes a classic DNS (Domain Name System) issue. The ability to successfully ping by IP address (10.1.1.1) confirms that Layer 3 connectivity exists between the PC and the server. The failure to ping by hostname (server1.example.com) indicates that the PC is unable to resolve the hostname to its corresponding IP address. This is almost always caused by an incorrect or unreachable DNS server configuration on the client.

WPA3 is the latest and most secure Wi-Fi security standard. For a corporate environment, WPA3-Enterprise is the recommended choice as it combines the strong encryption of WPA3 with 802.1X authentication, providing individual user authentication through a RADIUS server. This is significantly more secure than pre-shared key (PSK) methods. WEP and WPA are obsolete and highly insecure.

The command ip route 0.0.0.0/0 192.168.1.254 configures a static default route. The destination 0.0.0.0/0 is a special address that matches all possible IP destinations. The next-hop address 192.168.1.254 tells the switch where to send any packet that does not have a more specific match in its routing table.

A client needs its own unique IP Address and Subnet Mask to communicate on its local subnet. To communicate with devices on different subnets (i.e., beyond its local network), it must also have a Default Gateway address configured. The default gateway is the router interface to which the client sends all traffic destined for remote networks. DNS is needed for name resolution, not basic IP communication.

This statement is true. The core architecture of Aruba Instant APs (IAPs) is the Virtual Controller. In a cluster of IAPs on the same Layer 2 network, one AP is elected to function as the master, or Virtual Controller. The administrator connects to this single Virtual Controller to configure the entire cluster, and the configuration is then synchronized to all other member APs. If the master AP fails, another AP in the cluster is elected to take over the role seamlessly.

VSX is supported on the Aruba CX 6400 (and CX 8xxx/9300/10000), while VSF stacking is not supported on the 6400. A VSX pair keeps two independent control planes, synchronizes MAC, ARP and STP state over the ISL, and presents multi-chassis LAGs, so dual-homed devices get active-active links that survive the failure of either switch. STP blocks redundant links (active-passive), and VRRP only provides first-hop gateway redundancy. VSX does not apply to CX 6300 switches; on 6300/6200 access switches the equivalent resiliency option is a VSF stack.

In Campus AP (CAP) mode the AP is managed by an Aruba Mobility Controller/Gateway, and the forwarding mode is set per SSID in the virtual AP profile (forward-mode {tunnel | bridge | split-tunnel | decrypt-tunnel}). The employee SSID can use tunnel mode, so the AP sends that traffic in a GRE tunnel to the gateway for policy enforcement, while the guest SSID uses bridge mode and the AP forwards guest traffic directly onto the local wired network. (AOS 10 uses per-WLAN Tunnel or Bridge forwarding for the same result; its 'Mixed' mode means one WLAN whose clients are bridged or tunneled depending on the assigned VLAN.) Instant and standalone APs are not managed by a Mobility Gateway, and Spectrum Monitor is a non-serving analysis mode.

When a device does not have an 802.1X supplicant, it will not respond to the EAP requests from the switch, and dot1x authentication will time out. By configuring MAC Authentication as a fallback method, the switch will then attempt to authenticate the device using its MAC address against the RADIUS server. This is a common strategy for supporting devices like printers or IoT sensors on 802.1X-enabled ports.
