What does DDoS stand for?
Dynamic Denial of Service
Data Distribution over Secure
Direct Denial on Servers
Distributed Denial of Service
Distributed Denial of Service (DDoS) refers to an attack where multiple compromised systems are used to flood a target. This overwhelms resources and disrupts service, making other definitions inaccurate.
Which protocol is commonly used for secure remote management of Cisco devices?
Telnet
FTP
HTTP
SSH
SSH encrypts management traffic and provides secure authentication. Telnet, HTTP, and FTP transmit data in clear text.
Which Cisco IOS command sets an encrypted privileged EXEC mode password?
set password
enable secret
configure password
enable password
The 'enable secret' command configures an MD5-hashed password for privileged mode. The 'enable password' is stored in plaintext by default and is less secure.
Which type of firewall inspects traffic based on IP addresses and port numbers?
Packet-filtering firewall
Next-generation firewall
Application-layer firewall
Proxy firewall
Packet-filtering firewalls examine IP and port information to allow or block traffic. Other firewall types operate at higher layers or offer additional features.
What does VPN stand for?
Virtual Private Network
Virtual Port Name
Virtual Public Network
Variable Private Node
A Virtual Private Network (VPN) creates an encrypted tunnel for secure communications. The other terms do not reflect the standard abbreviation.
Which Cisco feature helps prevent ARP spoofing attacks on switches?
Dynamic ARP Inspection
VLAN Trunking Protocol
BPDU Guard
Port Security
Dynamic ARP Inspection (DAI) intercepts and validates ARP packets to stop spoofing. BPDU Guard protects against STP attacks and VLAN Trunking Protocol is for VLAN management.
Which ACL statement correctly permits traffic from 192.168.1.0/24 to any destination?
access-list 100 permit ip 192.168.1.0 255.255.255.0 any
access-list 100 permit ip 192.168.1.0 0.0.0.1 any
access-list 100 permit ip 192.168.1.0 0.0.0.255 any
access-list 100 permit ip 192.168.1.0 0.0.255.255 any
Cisco IOS uses wildcard masks, where 0.0.0.255 matches all hosts in a /24 network. Using a subnet mask instead of a wildcard mask or incorrect wildcard patterns will not yield the intended results.
Which IKE phase establishes the ISAKMP security association for an IPsec VPN?
Phase 3
Phase 0
Phase 1
Phase 2
IKE Phase 1 sets up the initial secure channel (ISAKMP SA) for negotiating IPsec parameters. Phase 2 negotiates the IPsec SA for data encryption.
Which encryption algorithm is considered more secure and efficient than 3DES for VPNs?
AES
MD5
DES
RC4
AES offers stronger security and better performance compared to 3DES. DES and RC4 are older and less secure, while MD5 is a hash function, not an encryption algorithm.
Which Cisco solution provides intrusion prevention through signature and anomaly-based analysis?
Cisco NAC
Cisco IPS
Cisco AnyConnect
Cisco IOS Firewall
Cisco Intrusion Prevention System (IPS) uses signature and anomaly techniques to detect and block malicious traffic. IOS Firewall provides basic stateful inspection, while NAC and AnyConnect focus on access control and VPN.
Which remote access VPN type uses SSL/TLS instead of IPsec?
DMVPN
GRE Tunnel
SSL VPN
IPsec VPN
SSL VPNs utilize TLS/SSL for secure connections through a web browser or client. IPsec VPN and GRE are different tunneling protocols and do not use SSL/TLS.
Which command disables the HTTP server on a Cisco router to reduce its attack surface?
disable httpd
shutdown http service
no ip http server
no ip secure http-server
The 'no ip http server' command turns off the built-in HTTP service on Cisco IOS. Disabling unnecessary services minimizes potential vulnerabilities.
What is the default action at the end of a Cisco IOS access control list if no other rules match?
Deny all traffic
Log all traffic
Forward traffic to CPU
Permit all traffic
Cisco IOS ACLs have an implicit 'deny all' at the end, which blocks any traffic not explicitly permitted. There is no default permit behavior for ACLs.
In IPsec, which mode encrypts only the payload of IP packets while leaving headers intact?
AH
Tunnel mode
Transport mode
GRE
IPsec transport mode encrypts only the payload and ESP trailer, preserving the original IP headers. Tunnel mode encapsulates and encrypts the entire packet with a new header.
Which best practice secures SNMP on Cisco devices?
Enable SNMP traps without encryption
Use SNMPv3 with authentication and encryption
Use SNMPv1 community strings
Allow SNMP from any host
SNMPv3 adds authentication and encryption, protecting management traffic. SNMPv1 community strings are sent in clear text, making them insecure.
Which security property ensures past encrypted sessions cannot be decrypted if long-term keys are compromised?
Symmetric Exchange
Session Reuse
Perfect Forward Secrecy
Key Rolling
Perfect Forward Secrecy generates unique session keys for each session so that compromising long-term keys does not allow decryption of past sessions. Key Rolling, Session Reuse, and Symmetric Exchange do not provide this guarantee.
Which Diffie-Hellman group is commonly recommended for a balance of strong security and performance in IKEv2?
Group 14
Group 1
Group 5
Group 2
DH Group 14 (2048-bit MODP) offers robust security with acceptable performance. Group 1 and 2 use weaker key sizes, and Group 5 is older and less commonly used today.
In DMVPN Phase 3, which NHRP feature enables direct spoke-to-spoke tunnel creation?
IPsec transform set
NHRP redirect
mGRE
NHRP registration
NHRP redirect messages allow the hub to instruct spokes to form direct tunnels, improving efficiency. NHRP registration is for initial spoke registration, while mGRE and IPsec transform sets configure tunneling and encryption.
In Cisco zone-based firewall architecture, which component defines the actions applied to classified traffic?
class-map
policy-map
service-policy
zone-pair
A policy-map associates classes of traffic (class-maps) with specific actions like inspect or drop. Zone-pairs bind zones, and service-policy applies these policies to interfaces.
Which protocol automates certificate enrollment for IPsec on Cisco routers using PKI?
LDAP
FTP
SCEP
RADIUS
The Simple Certificate Enrollment Protocol (SCEP) automates certificate requests and distribution in Cisco IOS. LDAP, FTP, and RADIUS do not handle PKI certificate enrollment.
