An ACL is applied inbound on a router interface. The ACL consists of a single entry: access-list 210 permit tcp 172.18.20.0 0.0.0.31 172.18.20.32 0.0.0.31 eq ftp . If a packet with a source address of 172.18.20.14, a destination address of 172.18.20.40, and a protocol of 21 is received on the interface, is the packet permitted or denied?
Permitted
Denied
What is a characteristic of the two-tier spine-leaf topology of the Cisco ACI fabric architecture?
The spine and leaf switches are always linked through core switches.
The spine switches attach to the leaf switches and attach to each other for redundancy.
The leaf switches always attach to the spines and they are interlinked through a trunk line.
The leaf switches always attach to the spines, but they never attach to each other.
Which two scenarios would result in a duplex mismatch? (Choose two.)
Connecting a device with autonegotiation to another that is manually set to full-duplex
Starting and stopping a router interface during a normal operation
Connecting a device with an interface running at 100 Mbps to another with an interface running at 1000 Mbps
Configuring dynamic routing incorrectly
Manually setting the two connected devices to different duplex modes
A network technician is configuring SNMPv3 and has set a security level of auth . What is the effect of this setting?
Authenticates a packet by a string match of the username or community string
Authenticates a packet by using either the HMAC with MD5 method or the SHA method
Authenticates a packet by using either the HMAC MD5 or 3.HMAC SHA algorithms and encrypts the packet with either the DES, 3DES or AES algorithms
Authenticates a packet by using the SHA algorithm only
What are two types of attacks used on DNS open resolvers? (Choose two.)
Amplification and reflection
Resource utilization
Fast flux
ARP poisoning
Cushioning
An ACL is applied inbound on a router interface. The ACL consists of a single entry: access-list 101 permit udp 192.168.100.0 0.0.2.255 64.100.40.0 0.0.0.15 eq telnet . If a packet with a source address of 192.168.101.45, a destination address of 64.100.40.4, and a protocol of 23 is received on the interface, is the packet permitted or denied?
Denied
Permitted
