HCIA TEST 2

When this router receives a packet with a destination IP address of 9.1.1.1, the router forwards the packet based on the route 9.1.0.0/16 because the matched bit number in this route is the largest.

The following figure shows a routing table. When this router receives a packet with a destination IP address of 9.1.1.1, the router forwards the packet based on the route 9.1.0.0/16 because the matched bit number in this route is the largest.

• True

• False

Layer 2 switches are data link layer devices that identify MAC addresses of Layer 2 data frames and forward Layer 2 data frames based on MAC addresses. In addition, they record mappings between MAC addresses and interfaces in the MAC address table.

• True

• False

In RSTP mode, both alternate and backup ports cannot forward user traffic but can receive, process, and send BPDU.

• True

• False

Which port will be assigned a designated port role?

The switch is operating using STP. All default parameters have been maintained. Which port will be assigned a designated port role?

• G0/0/1 of switch A.

• G0/0/2 of switch A.

• E0/0/1 of the hub.

• E0/0/2 of the hub.

After the keepalive function is enabled for a GRE tunnel, the local end of the GRE tunnel sends a keepalive packet to the remote end every 10s.

• True

• False

Which port will be blocked?

Both switches are operating using STP. With exception to those shown, all other default parameters have been maintained. Which port will be blocked?

• Port G0/0/1 of switchA.

• Port G0/0/2 of switchB.

• Port G0/0/1 of switch B.

• Port G0/0/2 of switch A.

According to the configuration of single-armed routing in the following figure, the administrative department and finance department can communicate with each other even the proxy ARP is disabled on the subinterface on R1.

• True

• False

What will occur as a result?

In the private network, RTA dynamically assigns a public address from the address pool to hosts without port translation. Host C wishes to access the public network while addresses are assigned to Host A and HostB. What will occur as a result?

• The first public address will be allocated to Host C, and Host A will be forced offline.

• The first public address will be allocated to Host C, and Host A will be forced offline.

• Host C will be unable to forward traffic over the public network.

• All hosts will have access to the public network through pool address swapping.

The authentication, authorization and accounting schemes and HWTACACS or RADIUS server templates created on AR routers take effect only after being applied to a domain.

• True

• False

Which SNMP version focuses on two main aspects, namely security and administration. The security aspect is addressed by offering both strong authentication and data encryption for privacy. The administration aspect is focused on two parts, namely notification originators and proxy forwarders.

• SNMPv1

• SNMPv2

• SNMPv2c

• SNMPv3
