IP Connectivity

Match each OSPFv2 network type or interface configuration on the left to its corresponding DR/BDR election requirement and default timer profile on the right.

When a router processes an incoming IP packet to make a forwarding decision, it evaluates matching candidate routes using a deterministic precedence hierarchy. Place the following routing decision criteria in the correct order of evaluation from first (1st) to last (4th).

Refer to the following routing table output from a Cisco router:

Codes: C - connected, S - static, R - RIP, O - OSPF
Gateway of last resort is not set

10.0.0.0/8 is subnetted, 4 subnets
O 10.1.1.0/24 [110/20] via 192.168.1.2, 00:04:12, GigabitEthernet0/0
S 10.1.0.0/16 [1/0] via 192.168.1.1, GigabitEthernet0/1
O 10.1.1.128/25 [110/30] via 192.168.1.3, 00:02:15, GigabitEthernet0/2
S* 0.0.0.0/0 [1/0] via 192.168.1.254

When the router receives a packet destined for host 10.1.1.130, which next-hop IP address will the router use to forward the packet?

Refer to the exhibit displaying an abbreviated routing table for router R1:

text
Gateway of last resort is 192.168.4.1 to network 0.0.0.0

S* 0.0.0.0/0 [1/0] via 192.168.4.1, Serial0/0/0
S 10.1.1.0/24 [1/0] via 192.168.1.1, GigabitEthernet0/0

O 10.1.1.64/28 [110/20] via 192.168.3.1, GigabitEthernet0/2

Router R1 receives an IP packet addressed to destination host $10.1.1.67$. Which next-hop IP address and outbound interface will R1 use to forward this packet?

An engineer wants to configure a floating static route on a Cisco router to serve as a backup for a primary route learned via OSPF (Administrative Distance 110). Which two statements correctly describe the requirements and operational behavior of this floating static route?

A network engineer is configuring a backup floating IPv6 static route on router R1 toward destination prefix $2001:\text{db8}:7410:\text{a1}::/64$. The next-hop router is identified by its link-local address $\text{fe80}::\text{cafe}:1$ over local interface $\text{GigabitEthernet0/0/0}$. The route must be configured with an administrative distance of $140$. Fill in the missing parameters in the command snippet below.

An enterprise router has populated its IPv4 routing table with the following entries:

text
D 10.50.0.0/16 [90/2560512] via 10.1.1.1, 01:12:40, GigabitEthernet0/0
O 10.50.12.0/24 [110/20] via 10.1.1.2, 00:45:12, GigabitEthernet0/1
S 10.50.12.80/28 [1/0] via 10.1.1.3
S 10.50.12.80/29 [250/0] via 10.1.1.4

The router receives a packet with a destination IP address of $10.50.12.85$. Which next-hop IP address will the router select to forward this packet?

A network technician is adding a secondary path on Router-HQ to reach the internal subnet $172.16.40.0/24$. The primary link currently learns this destination via EIGRP with an administrative distance of 90. To ensure the secondary static path through next-hop IP $10.1.1.2$ serves strictly as a backup when the primary link is down, which Cisco IOS command must be configured?

A Cisco router receives an IP packet and initiates a route lookup process to select the optimal path. Arrange the router forwarding decision logic steps in the correct sequential order from first to last.

Refer to the following IPv4 routing table snippet from a Cisco router:

text
Gateway of last resort is 192.168.100.1 to network 0.0.0.0

S 10.20.0.0/16 [1/0] via 192.168.1.1
D 10.20.30.0/24 [90/307200] via 192.168.23.3, GigabitEthernet0/0/2
O 10.20.30.64/27 [110/20] via 192.168.12.2, GigabitEthernet0/0/1
S* 0.0.0.0/0 [1/0] via 192.168.100.1, GigabitEthernet0/0/0

The router receives a packet with a destination IP address of 10.20.30.77. Which next-hop IP address will the router select to forward this packet?

A network operations engineer is provisioning IPv6 static routing on router Edge-Rtr. The design requirements specify:
1. All default traffic must be forwarded to the primary service provider gateway at global unicast address $2001:\text{db8}:1000:1::1$.
2. A backup static route for internal network $2001:\text{db8}:\text{abc}:10::/64$ must direct traffic to link-local next-hop address $\text{fe80}::2$ across exit interface GigabitEthernet0/0/1, functioning as a floating route to back up a primary OSPFv3 route (administrative distance 110).

Which TWO Cisco IOS configuration commands correctly fulfill these requirements?

An administrator is reviewing the following Cisco IOS command output from router HQ-R3, which is connected to a shared Ethernet LAN segment alongside other OSPFv2 routers:

HQ-R3# show ip ospf interface GigabitEthernet0/0
GigabitEthernet0/0 is up, line protocol is up
Internet Address 192.168.1.3/24, Area 0
Process ID 1, Router ID 10.3.3.3, Network Type BROADCAST, Cost: 1
Transmit Delay is 1 sec, State DROTHER, Priority 0
Designated Router (ID) 10.4.4.4, Interface address 192.168.1.4
Backup Designated Router (ID) 10.2.2.2, Interface address 192.168.1.2
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5

If both the current Designated Router (10.4.4.4) and Backup Designated Router (10.2.2.2) fail simultaneously, which statement correctly describes the operational outcome for HQ-R3 during the resulting election?

A network technician is configuring high availability on interface GigabitEthernet0/1 of a Cisco IOS router. The interface is currently assigned the physical IPv4 address $192.168.10.1/24$. The technician enters the command `standby 1 ip 192.168.10.1` under interface configuration mode. Which outcome will occur as a result of executing this command?

A network administrator intends to configure a backup floating static route on router R1 to reach destination network $10.50.0.0/16$ in the event that the primary route learned via OSPF fails. The administrator enters the following configuration command on R1:

`ip route 10.50.0.0 255.255.0.0 192.168.12.2 105`

What is the immediate impact of this configuration on router R1's routing table?

Router R1 learns routes to the remote destination subnet $172.16.50.0/24$ via OSPF, which operates with a administrative distance of 110. A network administrator wants to manually configure a backup floating static route toward $172.16.50.0/24$ using next-hop IP address $192.168.12.2$. This backup route must remain inactive in the routing table unless the primary OSPF route fails. Which command must be configured on router R1?

A network administrator is configuring IPv4 static routing on router R1. Router R1 currently learns the primary route to destination network $192.168.50.0/24$ via iBGP, which has an Administrative Distance of 200. The administrator must configure two static routes:
1. A standard static route to reach network $10.100.1.0/24$ via next-hop IPv4 address $172.16.1.2$.
2. A backup floating static route to reach network $192.168.50.0/24$ via next-hop IPv4 address $172.16.1.2$ that remains inactive until the primary iBGP route fails.

Which two `ip route` commands must the administrator configure on router R1?

A router receives its primary path to the 172.20.0.0/16 subnet via internal EIGRP. Which administrative distance value should be configured on a static route to ensure it functions as an inactive floating backup route until the primary path fails?

A network administrator is reviewing IPv4 static route syntax and operational characteristics on a Cisco IOS router. Which two statements regarding Cisco IPv4 static routing are correct?

A Cisco router receives an IPv4 packet destined for a remote network. Place the router forwarding decision and packet processing steps in the correct chronological order from first to last.

A network administrator needs to configure a static route on router R1 to reach the destination subnet $2001:\text{db8}:\text{fed}:10::/64$. The next-hop router's interface uses the link-local IPv6 address $\text{fe80}::2$ across the local GigabitEthernet0/0/1 point-to-point link. Which command must be entered on R1 to properly establish this route?
