300-410 Device Management Practice Test 2 — 15 Questions

Question 1

A network engineer runs the following command on Router R1:

R1# show policy-map control-plane
  Control Plane

Service-policy input: CoPP
    class-map: MANAGEMENT (match-all)
      100 packets, 5000 bytes
      5 minute offered rate 0 bps
      police:
          8000 bps, 1500 limit, 1500 extended limit
        conformed 95 packets, 4750 bytes; action: transmit
        exceeded 5 packets, 250 bytes; action: drop
        conformed 0 bps, exceed 0 bps

class-map: ROUTING (match-all)
      200 packets, 10000 bytes
      5 minute offered rate 0 bps
      police:
          16000 bps, 3000 limit, 3000 extended limit
        conformed 200 packets, 10000 bytes; action: transmit
        exceeded 0 packets, 0 bytes; action: drop
        conformed 0 bps, exceed 0 bps

Based on this output, what is happening to traffic matching the MANAGEMENT class?

Accepted Answer

Some management traffic is being dropped because it exceeds the configured police rate.. The output shows that for the MANAGEMENT class, 100 packets were offered, 95 conformed and were transmitted, but 5 exceeded the police rate and were dropped. This indicates some management traffic is being dropped due to policing.

Answer

All management traffic is being transmitted without any drops.

Answer

The management traffic is being rate-limited but no packets are dropped.

Answer

The police rate is too high, causing all traffic to be dropped.

Question 2

A network engineer runs the following command on Router R1:

R1# show ip sla statistics
IPSLAs Latest Statistics:

Round Trip Time (RTT) for Index 1
   Latest RTT: 10 ms
   Latest RTT (milliseconds): 10
   Number of successes: 100
   Number of failures: 0
   Operation time to live: 3000
   Operation frequency: 60 seconds
   Next operation start time: 00:00:45

Based on this output, what is the status of the IP SLA operation?

Accepted Answer

The IP SLA operation is successful and has a low RTT.. The output shows 100 successes and 0 failures, with a latest RTT of 10 ms. This indicates the IP SLA operation is functioning correctly.

Answer

The IP SLA operation has failed 100 times.

Answer

The IP SLA operation is not configured correctly.

Answer

The IP SLA operation is about to expire.

Question 3

A network engineer runs the following command on Router R1:

R1# show flow interface GigabitEthernet0/0
Interface GigabitEthernet0/0
  FNF: enabled
  Ingress IPV4/IPV6 flow monitoring: enabled
    Exporter: EXPORTER1
    Monitor: MONITOR1
  Egress IPV4/IPV6 flow monitoring: disabled
  Ingress MPLS flow monitoring: disabled
  Egress MPLS flow monitoring: disabled

Based on this output, what is the state of NetFlow on this interface?

Accepted Answer

NetFlow is only monitoring incoming traffic on this interface.. The output shows that NetFlow is enabled on the interface for ingress IPV4/IPV6 traffic, with an exporter and monitor configured. Egress monitoring is disabled. This indicates NetFlow is collecting data on incoming traffic.

Answer

NetFlow is fully enabled for both ingress and egress traffic.

Answer

NetFlow is not configured on this interface.

Answer

NetFlow is only monitoring MPLS traffic.

Question 4

Given the following partial configuration on router R1:

router eigrp 100
 network 10.0.0.0 0.255.255.255
 network 192.168.1.0 0.0.0.255
!
interface GigabitEthernet0/0
 ip address 10.1.1.1 255.255.255.0
!
interface GigabitEthernet0/1
 ip address 192.168.1.1 255.255.255.0
!
interface GigabitEthernet0/2
 ip address 172.16.1.1 255.255.255.0

What is the effect of this configuration?

Accepted Answer

EIGRP will only advertise the 10.1.1.0/24 and 192.168.1.0/24 networks; the 172.16.1.0/24 network will not be advertised and no EIGRP adjacency will be formed on that interface.. The EIGRP configuration uses classful network statements with wildcard masks. The network 172.16.1.0/24 is not included in any network statement, so EIGRP will not advertise or form adjacencies on that interface.

Answer

EIGRP will form adjacencies and advertise all three interfaces because the network statements use classful boundaries.

Answer

EIGRP will advertise all three networks because the network 10.0.0.0 command includes all interfaces with an IP starting with 1, 172, or 192.

Answer

EIGRP will not form any adjacencies because the network statements must use exact subnet masks instead of wildcard masks.

Question 5

Consider the following partial configuration on router R2:

interface GigabitEthernet0/0
 ip address 10.0.0.2 255.255.255.0
 ip ospf 1 area 0
!
interface GigabitEthernet0/1
 ip address 192.168.1.2 255.255.255.0
 ip ospf 1 area 0
!
router ospf 1
 router-id 2.2.2.2
 network 10.0.0.0 0.0.0.255 area 0
 network 192.168.1.0 0.0.0.255 area 0

What is the effect of this configuration?

Accepted Answer

OSPF will form adjacencies on both interfaces as intended; the configuration is redundant but functional.. The configuration has OSPF enabled on interfaces both via the ip ospf interface command and via network statements under the router. This is redundant but valid; the network statement will enable OSPF on any interface matching the network, but the interface already has OSPF enabled. The network statement will also enable OSPF on additional interfaces that match, but here both interfaces are already covered. The configuration works as intended.

Answer

OSPF will not form adjacencies because the interface and network commands conflict, causing OSPF to ignore the network statements.

Answer

OSPF will form adjacencies on both interfaces, but the router-id 2.2.2.2 will be overridden by the highest loopback IP.

Answer

OSPF will only form adjacency on GigabitEthernet0/1 because the network statement for 10.0.0.0 is incorrect.

Question 6

Given the following partial configuration on router R3:

ip access-list extended FILTER
 permit ip 10.0.0.0 0.255.255.255 any
 deny ip any any
!
route-map RMAP permit 10
 match ip address FILTER
 set metric 100
!
router eigrp 100
 redistribute connected route-map RMAP

What is the effect of this configuration?

Accepted Answer

Only connected routes with a prefix matching 10.0.0.0/8 will be redistributed into EIGRP with metric 100; all other connected routes are not redistributed.. The route-map RMAP is configured to permit routes matching ACL FILTER (which permits 10.0.0.0/8) and set their metric to 100. However, the route-map is applied to redistribution of connected routes. Only connected routes that match the ACL will be redistributed; the set metric command will apply metric 100 to those routes. Routes not matching the ACL will be denied (since the ACL denies all other traffic) and not redistributed.

Answer

All connected routes will be redistributed into EIGRP with a metric of 100.

Answer

No routes will be redistributed because the route-map sequence number is not specified.

Answer

The redistribution will fail because the route-map must specify a metric for EIGRP redistribution.

Question 7

Consider the following partial configuration on router R4:

interface GigabitEthernet0/0
 ip address 192.168.2.1 255.255.255.0
 ipv6 address 2001:db8:1::1/64
 ipv6 ospf 1 area 0
!
interface GigabitEthernet0/1
 ip address 10.0.0.1 255.255.255.0
 ipv6 address 2001:db8:2::1/64
 ipv6 ospf 1 area 0
!
ipv6 router ospf 1
 router-id 4.4.4.4

What is the effect of this configuration?

Accepted Answer

OSPFv3 will form adjacencies on both interfaces as intended because the router-id is correctly set and OSPFv3 is enabled on each interface.. The configuration enables OSPFv3 on both interfaces using the ipv6 ospf command. However, OSPFv3 requires a router-id to be set; here it is set to 4.4.4.4. Without a router-id, OSPFv3 will not start. The configuration is valid and OSPFv3 will form adjacencies on both interfaces.

Answer

OSPFv3 will not form adjacencies because the router-id must be an IPv6 address.

Answer

OSPFv3 will only form adjacency on GigabitEthernet0/0 because the router-id is not configured under the interface.

Answer

OSPFv3 will not form any adjacency because the network type is not specified.

Question 8

Given the following partial configuration on router R5:

interface GigabitEthernet0/0
 ip address 10.1.1.1 255.255.255.0
 ip pim sparse-mode
!
interface GigabitEthernet0/1
 ip address 10.2.2.1 255.255.255.0
 ip pim sparse-mode
!
router ospf 1
 router-id 5.5.5.5
 network 10.0.0.0 0.255.255.255 area 0

What is the effect of this configuration?

Accepted Answer

OSPF will form adjacencies on both interfaces, and PIM sparse-mode will operate normally; the configuration is valid.. The configuration enables OSPF on both interfaces via the network statement (since both are in 10.0.0.0/8). It also enables PIM sparse-mode on each interface. This is typical for multicast routing. OSPF will form adjacencies and PIM will operate. There is no conflict.

Answer

OSPF will not form adjacencies because PIM sparse-mode is enabled on the interfaces.

Answer

OSPF will only form adjacency on GigabitEthernet0/0 because the network statement does not match GigabitEthernet0/1.

Answer

PIM sparse-mode will not work because there is no rendezvous point (RP) configured.

Question 9

Consider the following partial configuration on router R6:

router bgp 65001
 bgp router-id 6.6.6.6
 neighbor 10.0.0.2 remote-as 65002
 neighbor 10.0.0.2 route-map SET-MED out
!
route-map SET-MED permit 10
 set metric 50

What is the effect of this configuration?

Accepted Answer

The route-map will set the MED to 50 for all routes advertised to neighbor 10.0.0.2, and all routes will be advertised.. The route-map SET-MED is applied to outbound updates to neighbor 10.0.0.2. It sets the MED (multi-exit discriminator) attribute to 50 for all routes advertised to that neighbor. However, the route-map does not have a match clause, so it matches all routes. This is valid; all routes sent to that neighbor will have MED set to 50.

Answer

Only routes that match a specific prefix will have MED set to 50; other routes will not be advertised.

Answer

The configuration is invalid because the route-map must have a match clause.

Answer

The MED will only be set if the neighbor is also configured with a route-map for inbound updates.

Question 10

What is the default OSPF dead interval on an Ethernet broadcast network?

Accepted Answer

40 seconds. The default OSPF dead interval is 4 times the hello interval. On broadcast networks (like Ethernet), the default hello interval is 10 seconds, so the dead interval is 40 seconds.

Answer

10 seconds

Answer

30 seconds

Answer

120 seconds

Question 11

Which EIGRP metric component is disabled by default?

Accepted Answer

Reliability. EIGRP uses a composite metric based on bandwidth, delay, reliability, load, and MTU. By default, only bandwidth and delay are used; reliability and load are disabled (their K values are set to 0).

Answer

Bandwidth

Answer

Delay

Answer

MTU

Question 12

Which BGP attribute is considered the highest priority (most preferred) in the BGP best path selection process?

Accepted Answer

Weight. BGP best path selection considers many attributes in order. The highest priority (first checked) is the weight attribute (Cisco proprietary), followed by local preference, locally originated routes, AS path length, origin type, MED, etc.

Answer

Local preference

Answer

AS path length

Answer

MED

Question 13

Which TWO commands can be used to verify the SNMP configuration on a Cisco IOS-XE device? (Choose TWO.)

Accepted Answer

show snmp. The 'show snmp' command displays SNMP engine ID, community strings, and traps. The 'show snmp host' command lists the configured trap receivers and their associated community strings. The other options either show unrelated information or do not exist.

Answer

show running-config | include snmp

Answer

show ip snmp

Answer

show snmp community

Question 14

Which TWO statements about the Cisco IOS-XE SSH server configuration are true? (Choose TWO.)

Accepted Answer

The hostname and domain name must be configured before generating RSA keys.. SSH version 2 is the default and recommended version. The hostname and domain name are required to generate the RSA key pair for SSH. The 'ip ssh version' command is used to set the version, but version 2 is default. The 'transport input ssh' command is applied to the VTY lines, not globally.

Answer

The command 'ip ssh version 1' is required to enable SSH.

Answer

The command 'transport input ssh' must be configured globally.

Answer

RSA key modulus size must be at least 2048 bits for SSH version 2.

Question 15

Which THREE symptoms indicate that a device's NTP synchronization is failing? (Choose THREE.)

Accepted Answer

The output of 'show clock' does not have an asterisk (*) next to the time.. NTP synchronization failure is indicated by the clock being unsynchronized ('*' missing from 'show clock'), NTP associations showing '.' instead of '*' in 'show ntp associations', and syslog messages about NTP synchronization loss. The 'show ntp status' shows the clock is synchronized if working, and 'ntp peer' commands are for configuration, not symptoms.

Answer

The output of 'show ntp status' shows 'Clock is synchronized'.

Answer

The command 'ntp peer 10.1.1.1' is configured.
