Which minimum configuration items are needed to enable Secure Shell version 2 access to R15?

Refer to the exhibit.

An administrator configures four switches for local authentication using passwords that are stored in a cryptographic hash. The four switches must also support SSH access for administrators to manage the network infrastructure. Which switch is configured correctly to meet these requirements?

Which MAC address is recognized as a VRRP virtual address?

Configure IPv4 and IPv6 connectivity between two routers. For IPv4, use a /28 network from the 192.168.1.0
/24 private range. For IPv6, use the first /64 subnet from the 2001:0db8:aaaa::/48 subnet.
1. Using Ethernet0/1 on routers R1 and R2, configure the next usable/28 from the 192.168.1.0/24 range. The network 192.168.1.0/28 is unavailable.
2. For the IPv4 /28 subnet, router R1 must be configured with the first usable host address.
3. For the IPv4 /28 subnet, router R2 must be configured with the last usable host address.
4. For the IPv6 /64 subnet, configure the routers with the IP addressing provided from the topology.
5. A ping must work between the routers on the IPv4 and IPv6 address ranges.

Refer to the exhibit.

Which action must be taken to ensure that router A is elected as the DR for OSPF area 0?
